Preparation

Hardware Requirements:

• A Windows PC
• A 3DS on 9.2 or lower
• A SD Card reader or some other adapter to allow you to copy files from your PC to the SD
• A DS flashcard that works on 4.5 (R4i, etc),
• A SD Card (preferably 16 GB to hold games, but even 4 GB should work)

Software Download Links:

• Dev Menu CIA (Look for either BigBlueBox CIA or GovanifY’s CFW. Google is your friend, the file name will be either BigBlueBox.cia or DecMenu_2x.cia)
• Gateway 3.0+ Launcher.dat and DS Exploit files.
• Gateway Downgrade for your region
• Emunand Dummy Data Creator (credits to piratesephiroth) http://gbatemp.net/attachments/drag_emunand_here-zip.11716/
• Emunand Tool http://gbatemp.net/threads/emunand-tool-release-and-support-thread.359239/
• Palantine CFW http://jheberg.net/captcha/palantine-cfw-2/
• Network Scanner - http://www.nirsoft.net/utils/wireless_network_watcher.html

Part 1 - Downgrading

1. Copy the Gateway Launcher.dat and Gateway.dg file to your SD Card.
2. Turn off wifi and open the 3DS Browser. Go into the settings and delete cookies/cache.
3. Optionally, reboot your 3DS.
4. Navigate to the browser with wifi on this time, and go to go.gateway-3ds.com.
5. The exploit will now load. Go over the options using the D-Pad and backup your NAND.
6. After the NAND backup is done, power off the 3DS by holding down the power button. Put the SD Card into your computer, and copy the NAND.bin somewhere safe. This is your fail-safe, so don’t lose it!
7. Put the SD card back into the console, with the NAND.bin still on it.
8. Go run the downgrade process (it’s the last one in the menu). Wait for it to finish. Once it’s done, reboot your system. Put the SD card into the computer and ensure Launcher.dat is still on it. Do not delete NAND.bin just yet.

Part 2 - Installing CFW

1. Now, copy the GW Installer DS file to your DS flashcard. Pop it into the console and run that file from your flashcard. When it’s done, press home and go into System Settings. Go into other settings —> profile and tap DS Profile. The Gateway menu will load once again. This time, run the format emuNand process. When it’s done, shutdown your 3DS.
2. Pop the SD Card back into your PC. Run the emuNand tool you downloaded earlier and press “Extract emuNand”. Save the file as emuNand.bin somewhere.
3. Now, drag the emuNand.bin onto the bat file that was downloaded. After a while, a resulting REDNAND.bin will appear.
4. In the emuNand tool, press “Inject NAND into emuNAND”. Select the REDNAND.bin file, and just ignore the warnings about not finding NAND.bin.
5. After it’s done, delete everything on the SD card. It should only be a LAUNCHER.DAT file.
6. Now, copy everything from the SD Card folder in Palantine CFW onto the SD card. Delete the launcher.dat, and rename the launcher_gw.dat to launcher.dat
7. Insert the SD card into the console and boot up. It will create software management information. Take the SD card out again and open it on your computer.
8. Now, in your SD card, there should be a Nintendo 3DS folder. Open it, and open the folder inside that. There should be another, so open that too. You should see a exdata folder.
9. Make a new folder (not inside the exdata folder, but in the same directory as it) called “dbs”. Go into the folder and make a blank text file, named “title.db” or “import.db”. Doesn’t matter which.
10. Insert the SD back into the system and go into Settings —> Data Management —> Software. It’ll ask to reset your software management information, so allow it to do so.
11. Now, go into Other —> Profile. Hold down the L button, and tap DS Profile. If all goes well, the bottom screen will flash white and the CFW will load. If not, simply reboot the system by holding down power and trying again. Make sure to hold L while you do it.
12. Now, once you’ve gotten into CFW, you’ll need your 3DS’ IP Address. You can use the tool you downloaded earlier (the network scanner) to find the devices from Nintendo. Note the IP (usually looks like 192.168.1.1xx)
13. Edit the run.bat file in the Palantine CIA folder. Replace the DevMenu_2x.cia part with the name of your CIA, and the IPTOMODIFY with your IP.

installcia IPTOMODIFY 1 DevMenu_2x.cia

installcia 192.168.1.155 1 DevMenu_2x.cia

22. Now execute run.bat by double clicking on it. It should return result-code of 0.

• If you get a failed to connect, make sure the IP is correct and the 3DS is connected to the Internet.
• If there’s another return code, try steps 8 and onward again.

23. Once you’ve succeeded, press Power —> Home and unwrap your new gift. You can now enter the CFW without holding L using the regular way.

Installing CIAs

1. Find a CIA to install. Google is your friend.
2. Copy the CIA to your SD Card.
3. Use the standard method to get into the CFW. Open the DevMenu and import away.

What I'm asking is, I use a 32gb SD Card that I share with my sister for her camera. As off right now she's not here so I don't have the 32gb SD to try this tutorial, but I do have the old SD that came with the 3DS, but since its capacity is 4gb, I don't have all the digital games that my 32gb has.
Can I use the 4gb SD for this exploit and then when I have the 32gb memory back use it too? Or should I just wait?

oh sorry.. yes, you can use this exploit now with the old sd card

 

[jomaper]

oh sorry.. yes, you can use this exploit now with the old sd card

And what happens if tomorrow I put the 32gb sd card?
Won't it conflict since it's supposed to be 9.2?

 

[ewin00]

Now you're able to install cia

wo ho ho its works now, can you recommend me some first cia file that i should add?

 

[Arras]

So what are the limitations? Can this allow you to install any 3ds game, 3dsware dsiware, homebrew? Is the emunand updatable as it is in Gateway?

I'm wondering this myself. Does any CIA work, or only ones that can be run on 4.5 or lower? And can the emulated CFW nand be updated?

 

[-LuCas-]

And what happens if tomorrow I put the 32gb sd card?
Won't it conflict since it's supposed to be 9.2?

You need to format emunand in the 32gb sd card

 

[jomaper]

You need to format emunand in the 32gb sd card

Oh okay, then I'll just wait
is it possible to use emunand with this?
Sorry for all the questions D:

Sorry for all the questions D:

with old sd ?

 

[jomaper]

with old sd ?

Without gateway, really. I'm already waiting for mine, but I have a few friends that won't get one so this might be helpful for them since I can lend them my DSTwo for this exploit.
So, yeah, can we get emunand on 9.4 with this? :B
I missed the days when I knew stuff about the scene, never really liked being the one making so many questions, but as much as I try and read, I don't really learn a lot ;_;

I think yes but I'm not sure.. Try asking those who have created the guide

 

[Chaldron]

Nope, no emuNand. There's no Gateway card. This only allows a 4.x sysNand + 4.x CFW for installing CIAs that either are less than 4.5 or patched CIAs.

 

[Drak0rex]

So then I -don't- want to use this.

 

[TheFlash-55]

My pc cant see my 3ds's ip how can i fix this ?

 

[TheFlash-55]

I think i screwed up about installing cfw.How i restart to install cfw again? But i want fresh install.Should i format system memory than i start to installing cfw steps? (I'm on 4.5E) Sorry for my english

 

[Drak0rex]

So what happens when you update the nand while in CFW?

 

[thuytinh266]

Hello, everyone

I have question I do extract like the guide on page one

however, I can not install CFW. there is two step I think something wrong:

is step 4
In the emuNand tool, press “Inject NAND into emuNAND”. Select the REDNAND.bin file, and just ignore the warnings about not finding NAND.bin. For this step I did not see the warning sign. It just finish 100% and I just close it up. I also wonder I did this step in my computer when my SD card still insert in my CPU. ( Is it right ? or do I need to copy REDNAND.bin to my SD and do this step?

in step 10 I think something wrong here

Insert the SD back into the system and go into Settings —> Data Management —> Software. It’ll ask to reset your software management information, so allow it to do so.

After I go to Data Management —> 3ds>>> Software it write there is no accessible software data DId I do some thing wrong I did everything the step above said.

so I just stop at step 10.

can someone please help me.

Is this as safe as using a GW? Heard this is dangerous :s

 

[AdityaNese]

So, if I have any game that has 4.X keys or lower (like games listed in the 4.X of this page) and install them as .cias, will they function/play?

 

[Chaldron]

So, if I have any game that has 4.X keys or lower (like games listed in the 4.X of this page) and install them as .cias, will they function/play?

Yep, along with any firmware-spoofed games. Newer games with 7.x+ save encryption won't work, however.

Is this as safe as using a GW? Heard this is dangerous :s

It's not dangerous per se, just more tricky to setup and has less benefits than GW.

Format the SD Card completely and restart from Step 1.

So what happens when you update the nand while in CFW?

The CFW is just sysNand, if you update it, you'll end up with a 9.4 3DS. Bad idea.

I think i screwed up about installing cfw.How i restart to install cfw again? But i want fresh install.Should i format system memory than i start to installing cfw steps? (I'm on 4.5E) Sorry for my english

Format system memeory, format SD Card.

My pc cant see my 3ds's ip how can i fix this ?

Can you show me the output of the wifi scanner? Ensure your 3DS has wifi on and connected.

So then I -don't- want to use this.

Maybe if you have no eShop games and no money for a Gateway, then yes. Or if you're just bored, yes. But as a long-term solution? Not until we get a higher version CFW, or the ability to install CIAs on a bootable emuNAND without GW.

 

[AdityaNese]

Thanks! SMTIV will allow me to pass time while waiting for gateway.

 

[dingooooo]

Finally got this to work.
I was getting a failed to connect error, but after temporarily disabling the WiFi password on my router it finally connected and installed.
