Uh-oh, what if I didn't back up the sysnand? I think I only backed up emuNAND...

Let me clarify, after following all the steps in the guide, I only have one NAND backup. I think that means I only backed up by SYSNAND, not my emuNAND.

The backup of the sysnand is the first step of the guide. With the gateway launcher you backup your SYSnand and with the emunand tool you backup your EMUnand. But maybe nothing is lost, take a look at this https://gbatemp.net/threads/my-health-and-safety-app-vanished-after-rxtools.399367/page-2

Ok, I tried to reinject sysNAND with success, the hs app is there, but it's icon is that of bbm. I went ahead and followed the rest of step 4a, creating a new hs.app through universal injector. After I injected it into my sysNAND, it appears without a title and no preview on home menu, and upon selecting, it says "error, please redownload form eShop."

Same for me with the h&s after the restore. Have you tried booting on rx-sysnand and launching bbm?

I will try it. But I'm having trouble launching rxtools from my system without internet. I've set it to the ctrb method, but I can't seem to launch rxmode: pressing R when the rxtools logo screen only force the system to shut down. I'd rather not do it through the browser, but it's extremely difficult to pull of when booting.

I already went ahead and started to restore my sysNAND, sorry for being hasty! But I will try to boot it up into rxmode. The thing is, my emuNAND and sysNAND are already unlinked. I don't really know what my state is at this point: two unlinked NANDS, but I can't get bbm to show up or inject and I have no access to cias. Both NANDs are on firmware 9.2, btw

Launching into rxmode worked! Thank you!

Now it says importing bbm failed b/c file is invalid?!!! (0xC8804478)

As a matter of fact, I can't install ANY cias through bbm on sysNAND. Any advice? You have gotten me quite far, I thank you for that!

jAquaD · Jan 11, 2016

Ok, I hate to keep double posting, but something different keeps happening each stage and I don't know how to fix it.

First, after being booting sysNAND into rxMode, I am finally able to access bbm. First time installing fbi and other cias, it failes. I shut down, rebooted into sysNAND rx mode again and try to reinstall those cias again, but now it tells me "program already exists, import canceled" when all of them are nowhere to be found.

This happened before, and I tried restoring my previous NANDS (emu and sys). I'm back to where I started, except no bbm on emuNAND, just sysNAND.

Any help would be greatly appreciated. I think this all happened because I was trying to update that damn Pokemon Bank... Everything was perfect yesterday until I updated that one software...

Another note, these cias do appear as installed on my system settings under software for sysNAND. I have gone back to my sysNAND system settings and deleted all cias that don't show up on homemenu. I don't know what that could have done, other than create a possibility to reinstall said cias.

Hello there !

I did the the update on the Emunand and the displayed version is the 10.3.0-28E. There's no RX prefix in front of it. Have I done something wrong ?
NB : When I'm going back to the Sysnand settings, displayed version is 9.2.0-20E.
Edit : Ok, I went into RXtools, injected in the Emunand, started Emunand, now RX-E is displayed.

What if my NANDs are linked? I've been injecting the NAND into both, emuNAND and sysNAND, but emuNAND always launches as rx 9.2

Should I try deleting one or both of my long alphanumerical character folders under the "Nintendo 3DS" folder, and reinjecting a NAND? Is that even possible?

Interesting to note, both emuNAND and sysNAND now have the same friendcodes and cartridge game update status. I have a feeling that's why BBM might not be installing, because the emuNAND is linked to sysNAND?

In the guide, I'm not supposed to even have an emuNAND when installing BBM, so I'm wondering if that's why my case is being so difficult.

Yes, I can launch gateway. I can do pretty much anything up to the point of getting H&S to launch without giving me an error message. How safe is downgrading to 4.5 then updating again? What do you mean by pretty much perfect? In that it's more refined? Sorry for all the questions, I don't want a brick.

I say "safe" because there were no bricks (that I can remember). And I say "perfect" because it is refined, as you say; the opposite of how buggy the downgrader to 9.2 is right now (is it better now? I haven't caught up yet).

EridiumMiner said:
But do I need to install the normal AGB firm anyway ?

The patched one. You shouldn't need it, but I do in fact have it patched and have had little problems (only 1 game hasn't worked for me).

Akira said:
Hi, got some few questions:

• I already installed RXTools 3.0(part2) before backing up my nand (part1), can i still do the part1, which is "nand backup" safely?
• It seems for emunand back up, the link(tool) you have is only for windows, I've searched and found this is it safe to use this as an option for OSX (Mac user here)
• I might use another entry point using HBL, so which is better Pasta or mini-pasta? (i'm a 9.2 user btw)
• If i decided to use PastaCFW, which version should i use? The version 1.3 beta or 1.2.1?

Sorry if this questions been asked already, just want iron out the doubts/questions in my head before proceeding with this.

1) Yes!
2) Yes that is good too!
3) It really depends on which one works better for you; it doesn't hurt to try both is what I'm saying

4) The latest I'd assume; I haven't used PastaCFW myself so I can't really say.

Deeptrap said:
I see more ppl , who have problems to execute the browser hax after running mini pasta.

is there a work around ? dont have a gateway card of ninja cube game

If you are following the Pasta part of the Tutorial then you don't ever need to use the browser. The Pasta section is pretty much the whole tutorial (yes, having the HBL makes it that easy)

Please help! I'm using an old American 3DSXL, which I just downgraded to 9.2.0-20U.
I was able to get through step 3 with seemingly no issues. However, in the step 4a, I can't get the system to boot into RxTools. Even if I hold L at startup, it just boots to the system menu.

In Part 4a, you are booting Decrypt9WIP, not RxTools. Is that what you mean?

DinckelMan said:
I noticed that my "Nintendo 3DS/Sysnand ID" folder has a new folder in it, with a new string there. Is that fine?

That should be okay, although I'm not really sure to be honest.

Pachko said:
Okay guys, have everything setup as showed in this tutorial, rxtools boots automaticly, i set it so that i boot into sysnand when i hold R during launch, installed 3ds cia game works good. My question is - how do i install GBA cia games from BigBlueMenu ( Title Manager), cause people say i have to install them both on Emunand and Sysnand? How do i even run BigBlueMenu from sysnand? I dont get what i am supposed to do.

If you did Part 4a, then you already have BBM in Sysnand. And if you did Part 5 after that, then you also have it in EmuNAND. You can use either Rxmode sysnand or emunand to run BBM in sysnand or emunand, respectively.

kedest said:
Is there a way to get the firm folder without using python?
I just like to keep my system clean, don't want to install something that I'll ony use once.

Other than someone sending you their own firm folder, then there's no other way.

Welcius said:
What exactly are we doing here? I don't understand (this is the end of part 1)

That part creates EmuNAND after installing BBM onto Sysnand. This way you have BBM on sysnand and emunand and can install cias to either nand. Then all you have to do after that is Part 2, which is setting up the rxTools files.

Ratatapa said:
Dumb questions

1) How do i check which version of RXtools i currently have installed?
2) IF there is a new update of Rxtools do I just take the new files and overite the old files on my Micro SD?

1) There's no way right now other than to look at the name of the rxtools zip you downloaded (rxtools 10-02 build in this tutorial's case)

AidanLumina said:
I have numerous reports that launching sliderhax twice in a row always results in an error. This does not happen to you, @samiam144 ?

Sliderhax doesn't work for me on the first try anyways so I can't really answer this lol. BTW, based on what urherenow said I'm thinking of updating the guide yet again, and I will probably point to your complete CFW zip if that's still okay with you

skullpatch said:
can't access 3ds internet browser at the moment is it alright to access EmuNAND9 through the HBL instead?

Yes!

urherenow said:
TL;DR whole thread but...

The tutorial needs to be fixed. I am tired of helping newbs out in private because they are setting up menuhax to autoboot without unlinking nands first, then wondering why emunand black screens on them......

urherenow said:
@samiam144 No offense, but I just started reading this tutorial myself... and it really sucks. It's incoherent. The very beginning of the tutorial repeats itself within the first minute of reading.

You leave it up to a newb to decide which nand to format, then you go into other stuff without explaining how to install a cia manager back into emunand, if that's what was formatted. It goes directly to "now you're ready to install .cia files!". Really?

"How to install Games, Updates, Patches, DLC, Homebrew, etc. using a BigBlueMenu / Title Manager / BBM"

pretty vague, and doesn't really belong in a tutorial that really should be to get people started. For instance... if everyone here starts using FBI to install DLC, they'll be pissed off and frustrated when they get no installation errors, yet don't see any DLC they installed (SSB, for example...)

You are also missing an important step after unlinking the NANDs. How to link the NNID again, if one was already set up (which is most likely) . This will make problem posts pop up all over the place the first time someone who used this tutorial tries to download something from the e-shop.

You're right man, it seems like it's been problem after problem after the influx of new users. I already have an idea of how I will reorganize and rewrite the guide and will definitely take your constructive criticism (seriously, no offense taken!) into consideration. The guide was written with the idea that the user will have more freedom in what they want to do rather than "do exactly what is written in exactly this order", but I think I will have to go that route now.This freedom is definitely not working out with regards to menuhax and unlinking nands, and so on.

Also I got one question about your last point: are you talking about linking the NNID to emuNAND? Because that has never caused any problems for me personally. I created emuNAND, updated it, and was able to use the eShop right away. Unless there's some problem I am not aware of (very probable lol).

And thanks for the N3DS tip (although I'd prefer if N3DS users follow the other guides I linked to in the OP, since I have no experience with the N3DS anyways and would probable be of no help in those cases

)

WOW! After loosing count of how many times I swaped the SD card between the PC and the 2DS, I finally managed to get this working! First downgraded from 10.3, then followed this tutorial and bam! CIA installation working as a charm!

THANKS A LOT!

General requirements:

The web browser app OR a way to use Ninjhax OR a Gateway flashcard

A DS flashcard only if your system is on 4.X or 6.X and you have no web browser

Firmware version requirements:
Old 3DS/XL
USA & EUR & JAP: Firmware 4.X-9.2
Each method's level of difficulty from Easiest to hardest:
Gateway > *hax (Homebrew Launcher) > FBI Injection > Downgrading + Palantine/PBT CFW

2DS
USA & EUR & JAP: Firmware 6.X-9.2
Each method's level of difficulty from Easiest to hardest:
*hax (Homebrew Launcher) > Gateway > FBI Injection
(*hax and Gateway are switched because Gateway is known to sometimes have issues with the Multirom menu loading on a 2DS)

N3DS/XL (not covered in this guide, read below)
USA & EUR & JAP: Firmware 8.X-9.2
Each method's level of difficulty from Easiest to hardest:
Gateway > *hax (Homebrew Launcher)
(Gateway is first only because it works even on browser-less N3DS models.)

------------------------------------------------------------------------------

Instructions for users that don't have the browser app on their system
For Old 3DS and 2DS models only.

If you do not have a browser, you will need to be on either 4.x or 6.x firmware, and you will need a DS flashcart that works on your 3DS.
If you are below 4.x and don't have a browser, you must use a physical game to update to either 4.x or 6.x.
If you are on 5.x and don't have a browser, you must use a physical game to update to 6.x.
You can use 3DSDB to see which games contain a 4.x or 6.x update.
If you are above 6.x firmware and you don't have a browser, your only chance to get CFW is to find someone that can setup Ninjhax for you. Ask in this thread or the official thread for more info.

Now, since you don't have a browser, you will need to follow this guide in a different order. It is recommended that you use two tabs to follow this tutorial; one to keep track of the following steps, and another to go the sections indicated.

Go to Part 2 and follow the instructions. This step will have you place the proper rxTools files on your SD card.

Go to the section Launching rxTools through the System Settings app - MSET! and do the steps for your specific firmware version (4.x or 6.x). This step will setup the MSET entrypoint on your 3DS. Ignore the steps that require the browser.

Now MSET should be setup. You should be able to access rxTools now by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile.

If rxTools works, congrats! Now we will try to get a cia installer on your sysnand.

Go to Part 4a and follow the instructions, but instead of choosing EMUNAND in lines 2, 7, and 8, choose SYSNAND.

You should now have FBI in sysnand! FBI is what you will use to install .cia files. Think of CIAs as a zip folder; when you install it, it will extract all its contents to the "Nintendo 3DS" folder on your SD card. Once a cia is installed, you can delete the .cia file.

At this point, you have two choices.

A) You can find a .cia of a browser that is compatible with your firmware. I do not know if it is safe to install the 7.1.0-16 to 9.5.0-22 browser on a lower firmware, so I will not tell you how in this guide. If you do decide to do this, you will then be able to do Part 1 normally and create your nand backup and Emunand. After that, you can do whatever other steps in the guide that you haven't done yet, such as setting up Menuhax (autobooting RxTools). I highly suggest you don't go this route, and instead choose the following choice.

B) You can update to 9.0.0-20 firmware now (and yes, a browser is included!). The only downside is that you will not have a backup of your current firmware in case you mess up. However, I have guided a handful of people through the process and am confident that you can do it if you follow the instructions carefully. The advantages is that you will be on a complete firmware (that many people are on) with the proper browser, and you will be able to setup Menuhax (autobooting RxTools) much quicker.

If you chose to go with option A, stop now! If you chose to go with option B, then let's continue!

Go to the section How to Update your 3DS/2DS to 9.0 or 9.2 and follow the instructions very carefully.

Once that's done, you should be greeted with a new Home Menu! You are now on 9.0, and you now have a browser.

Finally, you can go ahead and do Part 1 and do just the Old 3DS and 2DS users - No gateway or cubic ninja? Try FBI Injection! section.

Now you have Emunand and your nand backup!

OPTIONAL BUT RECOMMENDED: you can now unlink your nands. See why and how in the Emunand Information section.

OPTIONAL BUT RECOMMENDED: you can now update your Emunand. I recommend doing so after unlinking nands, but it is your choice. See why and how in the Emunand Information section.

Congrats! It was long, but it was worth it in the end right? Now you can install Menuhax to finally be able to autoboot rxTools. Just follow the Launching rxTools at boot - Menuhax! section.

One last thing: be sure to read the Understanding FBI section to get a better understanding of how to install games. Also check out the Dsi/GBA/NES/etc. support and Have a DS flashcard? sections for other cool stuff!

Updated for: rxTools 3.0 nightly
Date: 12-05-15_08-48(December 5, 2015 @ 8:48UTC)
Git commit: a08cfdd

Part 1 - Making your Nand Backup!

No Gateway or Homebrew Launcher? We got you covered!

1. Download EmuNAND9 (latest release)
Put Launcher.dat in the root of your SD Card

2. In your SD card, there should be a Nintendo 3DS folder. Open it, and open the folder inside that (has a long name of random numbers and letters); that is your Sysnand's ID folder.

If there are two or more ID folders, then do the following steps for both folders. One folder belongs to your 3DS. If there is another similar folder, it probably belongs to another 3DS that you inserted your SD card into. Ignore the "private" folder if there is one.

There should be another folder within, so open that too. You should now see an "extdata" folder. If you don't see a "dbs" folder as well, download this zip folder and put the "dbs" folder beside the extdata folder.

*Again, if the dbs folder already exists, and you have a title.db and import.db file inside, do not replace them!

3. Boot the 3DS/2DS and go into Settings —> Data Management —> Software. It’ll ask to reset or repair your software management information or sd card, so allow it to do so. Again, you do NOT have to do this if you already had the dbs folder and the two files inside your SD card.

4. Open your 3DS/2DS internet Browser and go to http://go.gateway-3ds.com/ to launch EmuNAND9.

5. Once in EmuNAND9, navigate to EmuNAND Manager Options and then Dump SysNAND to NAND.bin. This will create a NAND backup of your 3DS.

6. Turn off your 3DS. Find NAND.bin on your SD card and transfer it to your PC for safe-keeping (seriously). You don't need to keep it on your SD card.

Continue to Part 2.

Gateway card users:

If you have emunand set up and already installed a few CIA's, please note:
Gateway and rxTools use the EXACT SAME emunand, so any CIA you install in GW emunand will be seen and boot-able in rxTools.
You cannot launch rxTools while in GW emunand, and vice versa.

You only have to install a cia installer (FBI, BBM, Devmenu) to Emunand (and Sysnand if you want) using your Gateway, then follow only Part 2 of this tutorial.
Then just launch Rxtools by following Part 3 and that's it! CFW without needing the Gateway card, plus the ability to play GBA and DSi cias.

Users with access to the Homebrew Launcher:

Download EmuNAND9 (latest release)
Put Launcher.dat in the root of your SD Card
boot up your 3DS
Open your 3DS internet Browser and go to http://go.gateway-3ds.com/ to launch EmuNAND9.

Once in EmuNAND9, navigate to EmuNAND Manager Options and then Dump SysNAND to NAND.bin. This will create a NAND backup of your 3DS.

Turn off your 3DS. Find NAND.bin on your SD card and transfer it to your PC for safe-keeping (seriously.)

Now, in your SD card, there should be a Nintendo 3DS folder. Open it, and open the folder inside that (has a long name of random numbers and letters). There should be another folder within, so open that too. You should now see an "extdata" folder. If you do not see a "dbs" folder as well, download this zip folder and put the "dbs" folder beside the extdata folder.

*Again, if the dbs folder already exists, and you have a title.db and import.db file inside, do not replace them!

Put the SD back into the 3DS.
Boot the 3DS and go into Settings —> Data Management —> Software. It’ll ask to reset or repair your software management information or sd card, so allow it to do so. Again, you do NOT have to do this if you already had the dbs folder and the two files inside your SD card.

Setting up Ninjhax/*hax & PastaCFW:

For 3DS' between 4.0.0-7 and 9.2.0-20 (Ninjhax 1)
Go here and select your SYSNAND version
Follow ALL the steps under the "How do I run Ninjhax?" section. This will install Ninjhax Version 1.

For 3DS' between 9.0.0-X and 9.2.0-X (Ninjhax 2.5)
If using Cubic Ninja:
Go here and select your SYSNAND version
Follow ALL the steps under the "How do I run Ninjhax?" section. This will install Ninjhax Version 2.5

If using any other method to access the HBL:
Go here and select which game/app you will use to access the HBL. Then follow the instructions.

After all that is done, download FBI Cia installer and put the 3ds folder on the root of your SD card root.
Also download BigBlueMenu from the Digiex link here and place the BigBlueMenu.cia file on your SD card root.
SD:\3ds\FBI
SD:\BigBlueMenu.cia

If using Ninjhax 1, setup PastaCFW.
Download the latest zip and put the 3ds folder on the root of your sd card (merge if necessary)

If using Ninjhax/*hax 2.5, setup Mini-Pasta.
Place the "miniPasta" folder inside the "3ds" folder on your SD like this: SD:\3ds\miniPasta\

Now, boot the HBL, and select Pasta CFW/Mini-Pasta
Once you boot into Pasta, run the HBL AGAIN and start the FBI application
Next, select the BigBlueMenu.cia you put on your SD earlier and press A to install it (make sure on the top screen it says "destination: SD" and "Mode: Install CIA"
This installs BigBlueMenu to your home menu in sysnand.

Now that you have BBM on your sysnand, make a backup of your sd card!!!

Open your 3DS internet Browser and go to http://go.gateway-3ds.com/ to launch EmuNAND9.
Once in EmuNAND9, navigate to Complete EmuNAND Setup. Follow the instructions, and ignore the starter.bin warning. Wait for the EmuNAND creation process to finish.

Once that's done, you can put all your SD card contents back on your card.
You don't need to put NAND.bin back on your sd card unless you want to downgrade to 4.X

Proceed to do Part 2 and Part 3. Skip Part 4a, Part 4b, and Part 5, and read the rest of the guide.

Part 2 - Preparing rxTools!

Download the recommended RxTools build for this guide here
TEMPORARY MIRROR LINK: Here

If you choose to use rxTools 2.6 or 2.5.2, just follow the instructions in the readme found in the rxtools download. After doing so, you can skip to Part 3.

Download Python version 2.7

Direct Windows installer link

If you are using Windows, right-click the rxtools.rar and open Properties. If at the bottom, it says the file is blocked, check "Unblock" and Apply. This should take care of any problems you have with the following steps.

Mac users: If you're having problems running rxtools (black screens, Installation Suite errors, etc.) try extracting the rxtools zip using a reputable .zip extractor or a Windows PC (or virtualbox).

Backup and delete any "rxtools" folder that you may have on your SD card before doing the following steps!

1. Put the "rxtools" folder on your SD card root.

2. Run cdn_firm.py in the "Tools" folder. It will generate a firm folder in the same folder that cdn_firm.py is in. The firm folder must go into the rxTools folder like so: SD:/rxtools/firm
3. If your 3DS is below 7.x firmware: Get "slot0x25KeyX.bin" (Hint: google it, download link should be in the description of a certain youtube video ) (MD5: 817FD1BFFBA60F79CF8CDF19CAF28923). Put this file on your SD card root.

For ninjhax users, you also need to get the "rxtools" folder (found inside the ninjhax folder from the rxtools zip) and put it alongside your other homebrew apps, like FBI.

Part 3 - Launch rxTools for the first time!

To launch from the internet browser: boot up your 3DS
Open your 3DS internet Browser and go to https://dukesrg.github.io/?rxTools/sys/code.bin (you should bookmark this. To do so, turn off your WiFi, then attempt to connect to the URL. It will fail; now you can open the browser menu and bookmark it.)
If it fails or gives you an error, click the wrench icon and clear cookies and history before trying again. If that doesn't work, clear all save data as well (should be at the very bottom of the browser settings).

To launch from Cubic Ninja, start the game and go into the QR option to boot the homebrew launcher. Select rxtools!

If you installed the MSET exploit for rxTools, you can launch it by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile. For instructions to do this, see the section below, titled "Launching rxTools through the System Settings app - MSET!"

Hold L when the bottom screen glitches to get into the menu if it is sending you back to the homemenu!!!

It should show you an Installation Data Suite. Press A when it completes; it should then tell you that EmuNAND is not found; this is normal, we didn't create EmuNAND yet.

To setup rxTools to launch when your 3DS turns on, see the section titled "Launching rxTools at boot - Menuhax!" after completing Part 5.

Part 4a - Installing a CIA Installer
Only for users without a Gateway card or a Cubic Ninja game

Adapted from this thread (thanks @d0k3 and co.!)
Please visit that thread if you have any issues with this section.

Download BigBlueMenu from the Digiex link here and place the BigBlueMenu.cia file on your SD card root.

SD:\BigBlueMenu.cia

Download Decrypt9WIP all-in-one, the latest version.

Place the Launcher.dat on your SD card, overwriting the old one.

Go to http://go.gateway-3ds.com/ to launch Decrypt9WIP.

Navigate to SysNAND File Options and then Dump Health & Safety. Let the process finish.

Turn off your 3DS.

Download the Universal Inject Generator.

If you are using Windows, right-click the zip and go to Properties. If there is an option to unblock the zip, do that and press OK.

Extract Universal-Inject-Generator-master.zip and place the folder somewhere on your PC.

Insert your 3DS SD into your PC.

Find the hs.app file on your SD and place it in the Input folder that is inside the Inject Generator.

Place a copy of BigBlueMenu.cia in the Input folder as well.

Run go.bat. If there are no issues, you will find that there are two inject-ready .app files in the Input folder.

To finally inject BigBlueMenu into SysNAND, rename the BigBlueMenu-with-banner.app file to hs.app and place it on your SD, overwriting the one that is already there.

Launch Decrypt9WIP again, and navigate to SysNAND File Options.

Choose health&safety inject to inject the hs.app. Don't worry, it's not as dangerous as you may think.

Now, launch the rxTools menu (hold L during launch), and boot RXMODE SysNAND.

You will be booted to what appears to be regular SysNAND.

Navigate to the H&S app and it should now be the BigBlueMenu app (Title Manager)!

Launch BigBlueMenu.

Go to the SDMC tab. Basically, this is your SD card it is looking at.

Navigate to BigBlueMenu.cia and press A. Press A again to confirm.

You just installed your first CIA!

Continue to Part 5 now.

Download FBI.cia

1. Boot up your 3DS and launch rxTools. Hold L when the bottom screen glitches to get into the menu.

2. Press dpad RIGHT to go to Advanced Options -> Press A -> Install FBI -> Press A -> choose EMUNAND, then select "check TMD version".

3. Take note of the console region and the TMD version, and turn off your 3DS.

4. Open the rxtools download and open the "Tools/fbi_injection/[region]/[version]" folder and copy the "fbi_inject.app" and "fbi_inject.tmd" files to the SD card root dir.

5. Put the FBI.cia from the FBI download onto your sd card

6. Boot up your 3DS and launch rxTools. Hold L when the bottom screen glitches to get into the menu.

7. Press dpad RIGHT to go to Advanced Options -> Press A -> Install FBI -> Press A -> choose EMUNAND, then select "Install FBI". When it's done, it will ask what you want to do with the source. Select "keep" if you want to install FBI to sysnand later.

8. Now, return to the rxtools main menu and select RXMODE -> EMUNAND and launch the Health & Safety Information app, it should boot FBI instead

9. Select FBI.cia and press A to install it.

In your SD card, there should be a Nintendo 3DS folder. Open it, and open the folder inside that (has a long name of random numbers and letters); that is your Sysnand's ID folder.

If there are two or more ID folders, then do the following steps for both folders. One folder is for your Sysnand and the other is for your Emunand; if there is another similar folder, it probably belongs to another 3DS that you inserted your SD card into. Ignore the "private" folder if there is one.

There should be another folder within, so open that too. You should now see an "extdata" folder. If you don't see a "dbs" folder as well, download this zip folder and put the "dbs" folder beside the extdata folder.

*Again, if the dbs folder already exists, and you have a title.db and import.db file inside, do not replace them!

Should look similar to this:

Now, boot the 3DS/2DS and go into Settings —> Data Management —> Software. It’ll ask to reset or repair your software management information or sd card, so allow it to do so. Do this in Sysnand and Emunand!

10. You should now have a new FBI app on your home menu, use that to install your CIAs!

Part 4b - Gateway card users only

You are pretty much done. If you want to have a CIA installer in sysnand so you can install stuff (I recommend GBA and DSi only), then:

Download FBI (I recommend version 1.4.2 at least) and put the .3ds file on your gateway 3DS flashcard, and the .cia file on your 3DS SD Card

Launch the GW exploit, but hold L to get into the menu

Highlight the first option, "Boot Gateway Mode"

Hold B, and the text should change to "Boot Gateway Sysnand Mode"

While still holding B, press A.

Press X at the confirmation screen to boot into Sysnand with signatures patched.

Once in sysnand with sigs patched, press Select to bring up your Rom Multiloader

Select FBI

Use FBI to install FBI.cia to destination=SD

Now you can install any cia while in Sysnand rxMode without needing the GW card.

Part 5 - Creating EmuNAND!

We will now create EmuNAND!

Backup your SD card now.

Go back to the EmuNAND9 zip that you downloaded in Part 1.
Again, place the launcher.dat on your SD card, overwriting the other one.
Open your 3DS internet Browser and go to http://go.gateway-3ds.com/ to launch EmuNAND9.
Once in EmuNAND9, navigate to Complete EmuNAND Setup. Follow the instructions, and ignore the starter.bin warning. Wait for the EmuNAND creation process to finish.

Once that's done, you can put all your SD card contents back on your card.
You don't need to put NAND.bin back on your sd card unless you want to downgrade to 4.X

Let's recap.

This is what we've done up to this point:

We made a NAND backup - this is important in case you ever brick your 3DS.

We set up rxTools for accessing via the browser - this is not the only way to access rxTools, and it is actually the most inefficient way to do it. Read the rest of the guide for details.

We injected BigBlueMenu to Sysnand and used it to install BigBlueMenu again - this is beneficial because:

You can use it to install GBA and DSi games

You won't lose BBM when you update your EmuNAND.

We are now able to update EmuNAND to the latest version - this allows the highest game compatibility, and eShop access. Read the next section for instructions on how to do this, as well as what you should and shouldn't do regarding updating EmuNAND. I also highly recommend unlinking your nands before updating EmuNAND, to prevent accidental sysnand updates and issues with CIAs and Menuhax.

EmuNAND Information

Some users report their sysnand still being updated following the below steps. Unlinking your nands before attempting to update may avoid this. Please read this post before deciding to unlink nands: http://gbatemp.net/threads/guide-the-emunand-save-data-mega-guide-gbatemp-doesnt-deserve.378491/(Please, please, pleasseee read this!).

If you have an update nag on sysnand, follow these short steps to delete the update from your system first, reducing any risk of updating sysnand to be EXTREMELY unlikely. Do not do step 4 obviously, click "no"!

To update your emunand, only do so through the System Settings app.
Do NOT update if it asks you if you're "ready to start system update" or whatever it says whenever you boot your 3ds, OR through the Eshop. It will update your sysnand instead.

How to properly update emunand: Boot into Emunand, and launch System Settings. Make sure it says RX-E or RX3D in front of the version number to be sure that you are in emunand, and go straight to Other Settings -> System update without exiting the System Settings app.

If you need Emunand tool (for backing up your emunand), then you can find it here.

How to unlink nands (Requires formatting one of the NANDs):

Download TinyFormat

Place the .cia on your SD card

Boot into rxmode SysNAND if you want to format SysNAND, or rxmode EmuNAND if you want to format EmuNAND

Don't know how? Hold L when booting rxTools to get into the menu. From there you can select which rxmode you would like to access. Note: 2.5.2 users have to hold R instead.

Personally I formatted sysnand, so that all the stuff I had on my sysNAND that was transferred to my EmuNAND stays there.

Once you're in the specified, launch BigBlueMenu (injected version or .cia version)

Install the TinyFormat.cia

Press HOME and choose to launch TinyFormat

Follow the instructions to format the NAND you are in, and thus unlinking your NANDs

Turn off your 3DS after the process is finished

Reboot into SysNAND or rxmode EmuNAND and complete the Initial 3DS Setup.

Nands are now unlinked!

How it will look on your SD card:

The folder with the smallest size belongs to the nand you just formatted. Grab the database zip again and put the title.db and import.db in YourFormattedNandFolder/RandomNumbersAndLettersFolder/dbs, just like you did in Part 1: Line 2 & 3! Don't forget to go to Data Management in the Nand you formatted to let the 3DS "repair" your software management information!

----------------You are now ready to install CIAs! Read further to learn about RxTools' other features and capabilities!----------------

How to install Games, Updates, Patches, DLC, Homebrew, etc. using a BigBlueMenu / Title Manager / BBM

Download any .cia file. Don't ask where to get them. There is a certain iso site for 3DS games that you can find on Google though.

Place the .cia file(s) on your SD card. I recommend placing them in a CIA folder to avoid clutter.

Open RXMODE EmuNAND or SysNAND (depending on which nand you would like to access the .cia from).

Launch BigBlueMenu / Title Manager, or any other CIA Installer that you have installed.

Go to the SDMC tab.

Go to the location of the .cia file(s)

Highlight the .cia and press A.

Press A once more to confirm the installation.

Wait for it to finish.

If you want to delete the .cia file after installation (since it isn't needed anymore once installed), highlight the .cia and press X, then A to confirm.

Press HOME and you should get a notification that you have a new app.

This only happens if it's a new game, app, or homebrew that you installed. There is no notification if you just installed DLC, a game update, or a System App.

Unwrap the gift and enjoy!

DSi/GBA/NES/etc. support

The patched AGB_FIRM is no longer needed (but if you already have it, you can keep it, doesn't matter)

DSi games can be ran through sysNand, and reportedly emuNand as well. Install to sysNand to play them in sysNand; install to emuNand AND sysNand if you want to play them in emuNand. DSi cias must be installed to NAND destination (if using FBI).

GBA games can be ran through emunand, or sysnand. They still have to be installed to both emunand and sysnand if your nands are unlinked! GBA games should be installed to SD (if using FBI).
Personally I just install them to Sysnand and play them from there.

Have a DS flashcard?

If you have a DS flashcard that was able to be used on a 3DS at some point before Nintendo blocked it, you may be able to use it again! Note: The following method will not work for old DS flashcards that were blocked since the release of the original 3DS.

Note: You need to use a CIA installer other than BigBlueMenu. Use FBI or Devmenu_2x
Please read the Understanding FBI at the very bottom of this guide before using FBI.
If you don't want to read that, use Devmenu_2x, it is simpler to use.

Open the Gateway Ultra download and go into the "Blue Card Fix" folder.
There will be a bluecardfix.cia inside; put it on your 3DS sd card.
Insert your SD back into your 3DS.

On your 3DS:

Launch RxMode Sysnand and open FBI or Devmenu_2x

If using FBI: Press L to change Destination to Nand

Select bluecardfix.cia and press A to install it.

If using FBI: Choose to overwrite the title when it prompts you.

Once done, exit the CIA installer.

You should now able to use your DS flashcard on your 3DS.
Things to note:

If your DS flashcard still doesn't work, then it will probably never work on your 3DS.

You should be able to use your DS flashcard in any mode (Sysnand, RxMode, Devmode/Pasta Mode), but exiting the card will bring you back to regular sysnand.

Running a DS flashcard will remove your MSET exploit if you have one (see the next section).

You can use a DS flashcard to easily install the MSET exploit (see the MSET section).

Launching rxTools at Boot - Menuhax!

These steps will setup Menuhax, which we will configure to allow rxTools to boot the moment you turn on your 3DS/2DS! IMO this is the best way to launch rxTools.

Note: You must be on 9.0 - 9.2 firmware. This means your sysnand has to be on or between 9.0 to 9.2 system version. To update to 9.0 or 9.2, scroll down to the section How to Update your 3DS/2DS to 9.0 or 9.2 and follow the instructions, then come back here.

Second note: This will only work with rxTools 3.0 nightly (from September onwards I think). No one has found a way for it to work with rxTools 2.6 and under.

Download the Homebrew Starter Pack and extract the contents to your SD card root.

Download the Homebrew Launcher cia by yellows8 and place hblauncher_loader.cia on your SD card.

Put the SD card back in your 3DS.

Set a random theme on your 3DS, then change it back to the default theme.

Launch rxmode SysNAND (Hold L when booting rxTools to access it)

Open BigBlueMenu (or any other CIA installer)

Install hblauncher_loader.cia

Exit to the HOME menu; there will be a new gift. It is the Homebrew Launcher cia.

Launch the Homebrew Launcher via the Homebrew Launcher cia you just installed in SysNAND.

Once in the homebrew menu, run the menuhax_manager v2.1 installer and install menuhax.

(At this point, I also set a custom button setup so that it loads sysnand only when I hold R. This is Type 2 in the config menu.)

After all that, test if menuhax boots you into the homebrew menu at cold boot. Just turn off your 3DS and turn it back on. Be sure to hold a button (or not), depending on what config you chose. The default is to hold L during boot. In my example above, I don't have to hold anything to launch menuhax, but if I hold R, then menuhax won't launch.

Now to set it to boot rxTools instead, download the latest CTRBootManager. Extract the zip and rename the boot.3dsx that is in the download to ctrb.3dsx. Then place the ctrb.3dsx and boot.cfg from the CTRBootManager download onto your SD card root.

On your SD card, look for the file which name starts with "ropbinpayload". Open it with HxD or Notepad++. Maybe plain old Notepad will work too.

Press CTRL+F and search for boot.3dsx. There will be two results.

Change both to ctrb.3dsx and save the file.

Open up boot.cfg with notepad and change boot_hb.3dsx to boot.3dsx and save the file.

OPTIONAL: Open up boot.cfg with notepad and change this:

to this:

Now save the boot.cfg, eject your SD, and put it in your 3DS

When you turn on your 3DS, you should see the red screen, followed by the rxTools splash screen. If you chose a custom button setup in the Menuhax installer, keep that in mind. By default, you must hold L when booting to let Menuhax run at boot-up. In my case, I chose TYPE 2, and selected the button R. This means that Menuhax will always run at boot unless I hold R (which would bring me to sysnand instead of rxTools).

Launching rxTools through the System Settings app - MSET!

These steps will downgrade your System Settings in your sysNand to the 4.x or 6.x version, which is where we will install the exploit. It is the second best entrypoint to booting rxTools, in my opinion.

Note: You need to use a CIA installer other than BigBlueMenu. Use FBI or Devmenu_2x
Please read the section Understanding FBI at the very bottom of this guide before using FBI.
If you don't want to read that, use Devmenu_2x, it is simpler to use.

All users:
Want to launch rxTools via MSET so that you don't need to connect to the internet? Select your system version:

4.X

Use one of the following methods:

EASIEST METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download and put the .nds file (rxinstaller.nds) on your DS flashcard's SD card. Now run it with your DS flashcard and select "rxtools 4.x".

To install MSET with FBI, you need to have FBI 1.4.14 or higher on your sysnand. Simply launch rxmode sysnand, launch FBI, and press SELECT. Now, select "rxtools3.x 4.x". MSET should now be installed.

To install MSET with the internet browser, simply put the rxinstaller.bin (from the MSET folder) on your SD card root. Then launch the browser and go to http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin . It should freeze and crash, and send you back to the home menu. MSET should now be set up.

To launch rxTools via MSET, just turn on your 3ds, go to System Settings-> Other Settings-> Profile-> Nintendo DS Profile, and rxTools should boot.

5.X

If you don't have a DS flashcard: grab the rxinstaller.bin for rxTools from the "mset" folder and put it in your sd card root.

Go HERE (click the "CIA Format DLC's, Themes & Updates" link. Name of the thread is "[MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions)")

Download one of the following cias according to your region:

MSET-USA-4.0 0004001000021000
MSET-EUR-4.0 0004001000022000
MSET-JPN-4.0 0004001000020000

Place the .cia anywhere in your sd card.

Launch RXMODE SysNAND (Hold L when rxTools is booting to get into the menu first)

Launch Devmenu_2x or FBI

Install the .cia you downloaded above and then exit to the HOME menu.

EASY METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download and put the .nds file (rxinstaller.nds) on your DS flashcard's SD card. Now run it with your DS flashcard and select "rxtools 4.X DG". Then skip to step 11!

Note: the "DG" beside the system version number means "downgraded".

Open the 3DS browser, and enter this URL: http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin

Wait for a bit (it should crash and send you back to the home menu). If it doesn't crash after a minute, press HOME and it should crash.

If the next step (8) doesn't work, try clearing your cache and history before entering one of the above links.

Now you can launch rxtools by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile

6.X

If you don't have a DS flashcard: grab the rxinstaller.bin for rxTools from the "mset" folder and put it on your sd card root.

EASY METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download and put the .nds file (rxinstaller.nds) on your DS flashcard's SD card. Now run it with your DS flashcard and select the 6.X MSET option. Then skip to step 4.

Note: the "DG" beside the system version number means "downgraded". So if you are on 9.x using the 6.x mset, you would use "6.x DG". If you are on 6.x system version, you would use simply "6.x".

If you have FBI installed in sysnand, you can run it, press SELECT, and choose "rxtools3x 6.x" to install the exploit. Then you can skip to step 4.

If you used a DS flashcard in step 1, then skip to step 4! Open the 3DS browser, and go to one of these URLs: http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin

Wait for a bit (it should crash and send you back to the home menu). If it doesn't crash after a minute, press HOME and it should crash.

If the next step (4) doesn't work, try clearing your cache and history before entering one of the above links.

Now you can launch rxtools by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile

7.X - 9.2

If you don't have a DS flashcard: grab the rxinstaller.bin for rxTools from the "mset" folder and put it on your sd card root.

Go HERE (click the "CIA Format DLC's, Themes & Updates" link. Name of the thread is "[MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions)")

Download one of the following cias according to your region:
6.X MSET (2DS users must choose one of these or you may brick your 2DS!):
MSET-USA-6.0 0004001000021000
MSET-EUR-6.0 0004001000022000
MSET-JPN-6.0 0004001000020000

4.X MSET:
MSET-USA-4.0 0004001000021000
MSET-EUR-4.0 0004001000022000
MSET-JPN-4.0 0004001000020000

Place the .cia anywhere in your sd card.

Launch RXMODE SysNAND (Hold L when rxTools is booting to get into the menu first)

Launch Devmenu_2x or FBI

Install the .cia you downloaded above and then exit to the HOME menu.

EASY METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download and put the .nds file (rxinstaller.nds) on your DS flashcard's SD card. Now run it with your DS flashcard and select "rxtools 4.X DG". Then skip to step 11!

Note: the "DG" beside the system version number means "downgraded".

Open the 3DS browser, and enter this URL: http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin

Wait for a bit (it should crash and send you back to the home menu). If it doesn't crash after a minute, press HOME and it should crash.

If the next step (8) doesn't work, try clearing your cache and history before entering one of the above links.

Now you can launch rxtools by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile

How to Update to a Newer rxTools Version

Download the recommended RxTools build for this guide here
Download Python version 2.7 if you don't have it

Direct Windows installer link

If you are using Windows, right-click the rxtools.rar and open Properties. If at the bottom, it says the file is blocked, check "Unblock" and Apply. This should take care of any problems you have with the following steps.

Backup and delete any "rxtools" folder that you may have on your SD card before doing the following steps!

Place:
1. the "rxtools" folder on the SD card root.
2. the "firm" folder inside of the "rxtools" folder. How to get it:

Run cdn_firm.py in the "Tools" folder. It will generate a firm folder in the same folder that cdn_firm.py is in. The firm folder must go into the rxTools folder like so: SD:/rxtools/firm

For ninjhax users, you also need to replace the rxtools.3dsx and rxtools.smdh found inside the ninjhax folder in the rxtools download zip.

How to Update your 3DS/2DS to 9.0 or 9.2

If you want to boot rxTools as soon as you turn on your 3DS, then you need to set-up Menuhax; and to use Menuhax, you need to be on 9.0 - 9.2 firmware.
Warning: This can brick your 3DS if done incorrectly! Be sure that you follow the instructions carefully!

Requirements:

BigBlueMenu installed in sysnand (Part 4a if you don't have Gateway or Ninjhax) OR any other cia installer on Sysnand.

A rxTools 3.0 nightly (preferably the one linked in Part 2)

Also works on rxTools 2.5.2 (for those that can't launch 3.0)

Let's get started.

Click HERE

Click the CIA Format DLC's, Themes & Updates [Archive] result

Click View Full Version : CIA Format DLC's, Themes & Updates at the top of the page

Find the thread titled [MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions)

Scroll down to the section titled Updates

Download either the 9.2 modified update pack for your region, or a 9.0 or 9.2 Full Update Pack for you region

Once downloaded, open the archive and find the "updates" folder; place it on your SD card. There should be many cia files in that folder.

Example: SD:/updates/0004013000008003.cia

Download Sysupdater

Open the archive and put sysUpdater.cia on your SD card

Insert your SD card in your 3DS

Hold L while launching rxTools to get into the rxTools menu. If using rxTools 2.5.2, hold R instead.

Press DPAD RIGHT until you highlight ADVANCED OPTIONS, then press A. Skip this step if using rxTools 2.5.2

Go down to DEVMODE or PASTA MODE and press A

After a few seconds, you should now be in sysnand; firmware spoofing is disabled but cias can still be launched in this mode.

Launch you CIA installer

Install sysUpdater.cia (Destination: SD if using FBI)

Once installed, press HOME to see sysUpdater wrapped as a gift; unwrap it.

Launch sysUpdater

sysUpdater will ask you if you are sure you want to go ahead with the update; choose to accept it.

It will also tell you that you shouldn't be in Gateway mode, or have firmware spoofing. Do not worry about this, DEVMODE / PASTA MODE has no firmware spoofing, so sysUpdater will work as intended. Just be absolutely sure you are in DEVMODE / PASTA MODE (line 13), not RXMODE SYSNAND!

Wait for sysUpdater to finish. When it is done, your 3DS will reboot into 9.0 or 9.2 firmware! You can now follow the steps to use Menuhax if you'd like.

How to move Games, Saves, Themes, and Emunand to a new SD card

Get Emunand Tool

Insert your old SD card in your PC

Open Emunand Tool and select "Extract EmuNAND"

Save it somewhere on your PC (as "emunand.bin" if you want)

Backup all your SD card files to your PC

Eject your old SD card

Put Gateway's launcher.dat on your new SD card

Format emunand on your new SD card via the gateway menu

Turn off your 3DS

Insert your new SD card in your PC

Open Emunand Tool and select "Inject NAND to emuNAND"

Select the emunand.bin you made in step 3 & 4

Close Emunand Tool when done

Put backup of SD card files (from step 5) on your new SD card

Done, emunand and files (saves, games, etc.) have been transferred to your new SD card!

Understanding FBI

Unlike other cia installers, FBI allows the user to install to either Nand or SD. 3DS games, game updates, DLC, GBA games, and homebrew, are meant to install to SD. System titles (such as the Internet Browser, or MSET), and DSi games install to Nand. To better understand Nand and SD destination, take a look at these infographics, courtesy of @pakrett and @Hashtastrophe respectively:

-----------------------------------------------------

F.A.Q

If you get the "022-2634" when trying to access the eShop on the latest EmuNAND, try this (thanks to @Nestar):

1. Backup your emuNAND.
2. Backup all emuNAND files (ticket.db etc.) with rxTools.
3. Backup the content of your SD card.
4. Format emuNAND.
5. Recover your SD card content and boot rxTools in emuNAND.
6. Update to 10.3.0-28X and boot into emuNAND again.
7. Go to system settings and to NNID at the top; follow instructions.
8. Boot emuNAND and start the eShop; simply restart the 3DS if it keeps looping after the password input.
9. Once in the eShop, close it and shut down.
10. Recover your whole SD card once more. *
11. Inject emuNAND backup.
12. Inject all emuNAND file backups.
13. Start the eShop in emuNAND and it should refresh your software.
14. And now you should have emuNAND eShop access without any loss ofStreetPass/Save/Friend/etc. data.

Yes you will be able to access the eShop in EmuNAND, using your NNID.

I am actually editing the guide right now, but if you ever need an older version I can send it to you. I don't know when I'll be done but I can tell you that the guide will be very different (reorganized mostly).

Yes, as long as you use TinyFormatter in SysNAND (thus, formatting SysNAND).
No problem

Also I got one question about your last point: are you talking about linking the NNID to emuNAND? Because that has never caused any problems for me personally. I created emuNAND, updated it, and was able to use the eShop right away. Unless there's some problem I am not aware of (very probable lol).

And thanks for the N3DS tip (although I'd prefer if N3DS users follow the other guides I linked to in the OP, since I have no experience with the N3DS anyways and would probable be of no help in those cases )

When you format ANY NAND through system settings, your NNID is unlinked from your CONSOLE (not just the NAND) on Nintendo's servers. So when you format sysnand, then try downloading a demo or purchasing a game from eshop on emunand, it doesn't ask you to set up your NNID because it thinks it is setup already, but instead errors out on the server side, because the NNID your emunand is using is no longer associated to your console on their end...

Very weird, I haven't had this problem when I formatted my sysNAND..
I legitimately had no idea; do you think you can send me a link or provide an overview of what must be done?

I've never tried this tinyformatter thing that you speak of. If it unlinks your nand without talking to Nintendo's servers, then that's all you will ever need, as long as people actually follow your tutorial and use it, instead of system settings.

Through system settings, You need to re-setup your NNID (so you must not be using 4.x mset, unless you have a way into the eshop via that nand). I can't remember the exact steps off the top of my head, but you should be able to just use the NNID button from system settings. If that method happens to complain about updating your system (again, I'm not sure at this point and I don't feel like formatting any of my sysnands right now) Then you either need to install the latest Nver and launch freemultipatcher, before using that button, or if that doesn't work, you'll need to follow any guide that will help you access eshop from whatever nand you just downgraded.

Downloading a demo with no NNID set up, will ask you to configure an NNID. Both nands will work in eshop once you do this. They will both throw errors out if you don't (when entering the shop on the nand that thinks it is still set up, or when you try to download with the nand that you just formatted)

Alright thanks for the info bro. I've updated the guide but made no mention of linking NNIDs for now. Hopefully TinyFormat bypasses this issue (I haven't used it either).
Please let me know of any more suggestions you have, it's appreciated. I too am getting tired of all these questions haha.

@hudhair Just letting you know I've updated the guide now. If there are any issues or typos please let me know

And once again @wormdood and @Nestar you both have been a big help, thank you very much.
