SYSNAND-ONLY USERS: DO NOT BOOT GW MODE ON 11.3+ - YOU WILL LOSE B9S AND BE LEFT ON A STOCK FIRMWARE
I highly advise against the use of GW on SysNAND-Only Setups.
GW currently DOES NOT support firmwares 11.3//11.4 - B9S does not change that!
If you're on 11.3+ - Don't even try to use GW. Use Luma3DS or any other CFW that has confirmed support for 11.3+ firmwares.

Setting up GW with Luma3DS' chainloader

Requirements: SysNAND or EmuNAND on 11.2 or lower!
Tested and working on B9S 1.2 (Luma3DS 8.0)

1. Download the v2gw.zip attached to this post.
2. Extract the "arm9loaderhax.bin" from v2gw.zip to your /luma/payloads/ folder.
3. Rename that very "arm9loaderhax.bin" you just extracted to "v2gw.bin" or to whatever you want. However, step 12 will assume v2gw.bin was used, you can edit that reference to meet whatever you decided to name it.
4. Download GW's ‘arm9loaderhax.bin.zip‘ file.
   • On their main home page. Under the post titled: "GATEWAY 4.0B PRIVATE BETA #2"
   • Or on their openly public Private Beta Program page, on this page it'll be under the "» arm9loaderhax for users with existing a9lh installs" section.
5. Extract GW's "arm9loaderhax.bin" file from their zip file to your /luma/payloads/ folder.
6. Rename that very "arm9loaderhax.bin" you just extracted to "gateway.bin"
7. Make sure you have the latest GW's Launcher.dat on the root of your SD Card.
8. This dev-build of BootCTR9: https://gbatemp.net/threads/release-the-bootctr9-release-thread.435347/page-3#post-7370533
9. Extract the "boot.firm" file from the BootCTR9-firmv2.zip to your /luma/payloads/ folder.
10. Rename that very "boot.firm" you just extracted to "down_BootCTR9.firm" or to whatever you want that is allowed by Luma3DS' payload chainloader.
    - Other button options: https://github.com/AuroraWright/Luma3DS/wiki/Other-features-and-notes#payload-chainloading
11. Extract the "boot_config.ini" file from from the BootCTR9-firmv2.zip to the root of your SD Card.
12. Open the "boot_config.ini" file and overwrite everything with the following:
    

    [BOOTCTR9]
    key_delay = 1000
    
    [DEFAULT]
    path = /luma/payloads/v2gw.bin

13. You are now done. If you followed this tutorial, holding DPAD-DOWN at boot time, will load up Gateway Mode.
    - SysNAND-Only Users on 11.2 will be prompted to press 'L+R+SELECT' to boot SYSNAND. DO NOT PRESS THE BUTTON PROMPT ON 11.3+
    - GW EmuNAND users will automatically boot into their GW EmuNAND.

FAQ

Q: How do I boot into the GW Menu?
A: Hold L+Select, as soon as you see the Dragon Logo.

Q: Can I use my GW Blue Card?
A: Yes, but only while using Luma3DS. It will not work in GW Mode.

Q: Can I play online while in GW Mode?
A: Yes, sort-of. But you have to either:

• Use CTR-HTTPWN: https://github.com/yellows8/ctr-httpwn/releases
• or use this guide

Q: I'm getting a black screen!? HELP!?
A: Multiple reasons for that below:

• Modified SecureInfo_A - GW does not patch this. You'll need an untouched donor file of this.
• Using a RedNAND - GW only supports GW EmuNAND, it cannot boot RedNAND. Use the GW Menu or GodMode9 to make one.
• On SysNAND-Only Setups - Not having properly removed EmuNAND//RedNAND. Use GodMode to properly format your SD Card. But I advise you set one up.
• Trying to boot an 11.3//11.4 EmuNAND - GW does not support anything higher than 11.2
• If it's not listed, then who knows. Do you have a modified Home Menu or font? Those might not work at all in GW Mode.

Spoiler: Old Guide

I highly advise against the use of GW for SysNAND-Only setups.

11.3&11.4 Break GW. GW currently DOES NOT support 11.3 or 11.4. You will either brick or lose A9LH. More than likely it seems you will just lose A9LH.

Again, if you attempt to boot GW Mode, on a SYSNAND-Only Setup while on 11.3 or 11.4, you will lose A9LH. It does not matter if you safely updated to this firmware via another CFW that safely protects FIRM.

If you want to use 11.3+, you will not be able to use GW. Don't even try. Only use Luma3DS or other CFW that support 11.3+

If you are a Gateway3DS user, and have recently finished Plailect's A9LH Guide, then you should be on v2 A9LH. Unfortunately, at the time this thread was made, GW's a9lh.bin file is incompatible with Luma3DS' payload chainloading feature while on v2 A9LH.

So one way around this was to either forego using Luma3DS' payload chainloading, and use a boot manager that does work in initializing GW's a9lh.bin correctly. Like BootCTR9. Either you let BootCTR9 handle all payloads, or you set it up to chainload into Luma3DS and from there let Luma3DS do all the work.

Either way, some people might not like BootCTR9 (Big fan of BootCTR9, seriously thing is amazing~!)

So if you don't want to use the BootCTR9 method, then @Hayleia made a very stripped down boot manager that only loads /luma/payloads/gateway.bin. You still need GW's a9lh.bin in addition to this stripped down bootmanager, but that's all you need, these two files! No need for messy configs if you just want to stick with Luma3DS' payload chainloader.

Now on to the damn tutorials already~!​

Gateway Logo

1. Download the v2gw.zip attached to this post.
2. Extract the "arm9loaderhax.bin" from v2gw.zip to your /luma/payloads/ folder.
3. Rename that very "arm9loaderhax.bin" you just extracted to "down_v2gw.bin" or to whatever you want that is allowed by Luma3DS' payload chainloader.
Other button options: https://github.com/AuroraWright/Luma3DS/wiki/Other-features-and-notes#payload-chainloading
4. Download GW's ‘arm9loaderhax.bin.zip‘ file.
You have to get this directly from Gateway's site. Which is either:
A) On their main home page.
B) Or on their openly public Private Beta Program page, on this page it'll be under the "» arm9loaderhax for users with existing a9lh installs" section.
5. Extract GW's "arm9loaderhax.bin" file from their zip file to your /luma/payloads/ folder.
6. Rename that very "arm9loaderhax.bin" you just extracted to "gateway.bin"
7. Make sure you have the latest GW's Launcher.dat on the root of your SD Card.
8. You are now done. If you followed this tutorial, holding DPAD-DOWN at boot time, will load up Gateway Mode.
However, if you are a SysNAND Only User, and on 11.1 and using the 4.2 Launcher.dat, you will be prompted to press 'L+R+SELECT' to boot SYSNAND.
GW EmuNAND users will automatically boot into their GW EmuNAND.

Notes: To Boot into the GW Menu: Hold L+Select, as soon as you see the Dragon Logo.
To Force a Manual Gateway3DS RedCard Update: Hold R+Select as soon as you see the Dragon Logo.



No Gateway Logo (Not Recommend - Only for those allergic to the dragon logo - USE AT YOUR OWN RISK)

Notes: This version will de-init the screen by default, and as such you won't see the Gateway Logo. Don't worry it'll init once you land on the Home. Due to how this works, only GW EmuNAND users should consider using this. This is because SysNAND users will land on the SysNAND prompt nag.

1. Download the v2gw-de-init.zip attached to this post.
2. Extract the "v2gw.bin" from v2gw-de-init.zip to your /luma/payloads/ folder.
3. Rename that very "v2gw2.bin" you just extracted to "down_v2gw.bin" or to whatever you want that is allowed by Luma3DS' payload chainloader.
Other button options: https://github.com/AuroraWright/Luma3DS/wiki/Other-features-and-notes#payload-chainloading
4. Download GW's ‘arm9loaderhax.bin.zip‘ file.
You have to get this directly from Gateway's site. Which is either:
A) On their main home page.
B) Or on their openly public Private Beta Program page, on this page it'll be under the "» arm9loaderhax for users with existing a9lh installs" section.
5. Extract GW's "arm9loaderhax.bin" file from their zip file to your /luma/payloads/ folder.
6. Rename that very "arm9loaderhax.bin" you just extracted to "gateway.bin"
7. Make sure you have the latest GW's Launcher.dat on the root of your SD Card.
8. You are now done. If you followed this tutorial, holding DPAD-DOWN at boot time, will load up Gateway Mode without the Gateway Logo.

Tested on N3DS and O3DS by me, 2DS by @Hayleia.
Should work on either screen-init or non-screen-init v2 A9LH.



Important Note: Never update your SysNAND in Gateway Mode. It does not matter what Launcher.dat version you use, if you go ahead and update while in SysNAND Mode, you will either brick or lose A9LH+CFW and be on the latest stock firmware. This is because GW Mode does not offer FIRM protection in A9LH. Updating your GW EmuNAND is fine and safe, and is what Gateway actually recommends you do and use even when using A9LH.



!~Getting Black Screen After Dragon Logo and After Following This Guide~! (PLEASE READ)
Sounds like someone hasn't properly removed their EmuNAND//RedNAND with EmuNAND9. The Black Screen problem is common to people who skipped doing it properly and used a third-party tool like EaseUS or any other partition manager.

Since EmuNAND//RedNAND wasn't removed properly, traces were leftover and GW by default sees it, and tries to boot into this non-existent EmuNAND//RedNAND and fails. So how do we fix it? We use EmuNAND9 to preperly remove traces of it.

Part 5, Section V of the old A9LH guide covers this. However, I will list all relevant steps here.
Link: https://github.com/Plailect/Guide_R...ax)#section-v---removing-rednand-from-your-sd

The new guide also sort of mentions if in this new page, and does show you how to setup EmuNAND9:
Link: https://plailect.github.io/Guide/move-emunand

Files we'll need:
Latest release of EmuNAND9: https://github.com/d0k3/EmuNAND9/releases/latest

1. Copy EmuNAND9.bin from the EmuNAND9.zip to the /luma/payloads/ folder on your SD card and rename EmuNAND9.bin to y_EmuNAND9.bin
2. Backup every file on your SD card to a folder on your computer, all files will be deleted in the following steps
3. Reinsert your SD card into your 3DS
4. Hold (Y) at boot time to open EmuNAND9
5. Go to "SD Format Options...", then select the "Format SD (no EmuNAND)" option, and wait for it to finish
6. Press (B) to return to the menu, then press Select to safely eject your SD Card
7. Put your SD card back into your computer, and copy all the files you backed up previously, back into your SD Card
8. Reinsert your SD card into your 3DS, then press (Start) to reboot



Additional Note: You will still have to look into BootCTR9 if for some reason you want GW to be the default, as opposed to Luma3DS. This tutorial is meant more for the people who want Luma3DS as their main//default, and want to use Luma3DS' payload chainloader to boot into GW Mode.
Go to the following link for the tutorial on setting up GW as your main with BootCTR9.

Hi, this method work if I try to use Gateway in the latest fw support un emunand AND the sysnand for luma ?
Now I have my 3ds with Gateway but i want to install luma AND with luma enter to my emunand un Gateway .

Gateway will not work on the newest firware in EmuNAND and can brick your SysNAND. Gateways last fully compatible firmware is 11.2... People update 3 or 4 files in the EmuNAND firmware to 11.6 (AKA Frankernfirmware) to get Gateway playing a few extra titles but this is not really worth the effort. Use Gateway in a 11.2 EmuNAND and play the few incompatible games in Luma SysNAND.. I personally recommend going mostly Luma and putting all your favorite games in SysNAND and only using your Gateway for extra storage and games you don't play but might want to someday....

Use last supported fw for GW and not update it. Install luma and you have both, all games that I try work. Online play with spoof work

What is this games?
Never met them...

 

[JamieL]

Does anyone have a link to a working download for the gateway files you need for this method? Their site has disappeared and I can't seem to find arm9loaderhax.bin.zip.

 

[wawnord]

So, after a long time away from my N3DS i updated from A9LH to B9S including Luma to 10.01 and the SYSNAND to the latest 11.13.
My EMUNAND is further on 11.2
But my Gateway wont boot in EMunand now, there is no GW Splashscreen when i press Dpad down any more.
What i've forgotten or what i'm doing wrong?

 

[urherenow]

Weird... I could swear I replied last night, but now it's not here, and I have no notification that my post was deleted and I have no warning. I guess I'll try again.

This tutorial is too long. Assuming your default payload is Luma, and you don't have a payload set to "down" (change it if you do), simply extract the attached .zip to the root of your card. Now just hold "down" while you first hit your power button, and let go of it when you see the bootCTR screen. Done. On rare occasion, GW won't fully boot to the home screen and you'll just have to force a power off and do it again. I've never had to try more than twice. It seems a bit slow, so wait at least 30 seconds before you decide that it got stuck.

I've been using this setup for years and I'm on B9S. At some point, Luma stopped being able to boot the Gateway.firm directly, but BootCTR9 works. I haven't tried on fastboot3ds.

 

[Theone5000]

I've been using this setup for years and I'm on B9S. At some point, Luma stopped being able to boot the Gateway.firm directly, but BootCTR9 works. I haven't tried on fastboot3ds.

Is this tutorial both methods work. Botting up Gateway is not the problem when pressing down. However... When I boot up Gateway it gives me this wonderfull message:

You want to boot GW FASTBOOT: SYSNAND?
Press L+R+SELECT to continue.

Press (B) to go back.

Pressing B will do nothing.. Well obviously you don't want to goot GW Fastboot or you will lose your current setup (if I understand correctly).

Is there (years later) now fix available for the firmware i'm using:

SysNAND: 11.13.0-45E
Luma3DS: v10.0.1
GodMode9: v1.9.1
Boot9strap (B9S): 1.3

I believe my GW firmware is: GW3D 11.6.0-39E

at this point. gateway is useless. its likely best to grab what saves ya want and just fitch gateway.

No. GW only works up to 11.2. You can have 11.13 sysnand and boot 11.2 emunand (or 11.2 sysnand and use 11.13 for your emunand with Luma, even). 11.6 will never work, because the GW software will never be updated again. It's really only useful for the cheat engine now. And, I guess any game carts that work (if you really need more space for more games).

at any rate, I don't think you're using the correct files. You should see nothing about Fastboot. GW fastboot was an a9lh thing...

 

[Theone5000]

at this point. gateway is useless. its likely best to grab what saves ya want and just fitch gateway.

I am aware of that. I have Luma 3DS running and all, but the question was if there is a solution. Just for the sake of it.

No. GW only works up to 11.2. You can have 11.13 sysnand and boot 11.2 emunand (or 11.2 sysnand and use 11.13 for your emunand with Luma, even). 11.6 will never work, because the GW software will never be updated again. at any rate, I don't think you're using the correct files. You should see nothing about Fastboot. GW fastboot was an a9lh thing...

I don't need to update GW. It was working on 11.6 before I started using Luma. And I agree that Luma is better.I only have not found a solution to install multiple Pkmn CIA's. The EUR and US version overwrites and I want different versions. On Gateway this was wayyyy better. I had to just have a .3ds version and that's it. It could have 4 different pokemon versions next to eachother and create saves. On Luma the CIA overwrites it. If you know how to avoid this I don't need Gateway and can ditch it.

 

[urherenow]

Only way possible to work on 11.6 is by using a franken-firmware, so your emunand was all jumbled to begin with. I guess you could try avoiding it by decrypting and editing the .cia dumps to use different product IDs. Can’t promise saves will work after doing so though...

 

[lazyguy]

Been out of the 3ds scene for 3 or 4 years.

I'm wondering where I left off:
The last thing I've done with my n3ds (if I remember correctly) is gateway had some experimental hack where you it can inject code to one of the system apps to launch the hack.
Then it would install exploit during bootup where I hold L-trigger during power on and it will boot to homebrew launcher. My homebrew launcher is 1.1.0.
From the homebrew launcher, I can launch the gateway app and into gateway emunand cfw. (My system is on 9.2 and emunand is on 11.2)

I'm wondering how the gateway modifcations on sysnand affects potentially upgrading my system.

I've done a bit of reading and it seems like emunand is obsolete now.
The current latest fw is 11.13, how much am I missing between cfw and going from 11.2 -> 11.13. The only feature I've read so far that interests me is applying 60fps cheats.

Anyways, I would like the best of both worlds approach (cfw and gateway) and I don't care to be on latest firmware or anything.
Where do I go from here if I'm set on continuing gateway.

 

[SJWPURITAN]

I don't have my hands on a gateway card yet (soon I will).

Is it possible to test this without Gateway, or will I need it the card? I am using Emunand 11.2.

I have everything in place but when I try to boot the BootCTR payload, I get the error below then the ds shuts down:

[PANIC] Failed to load the [DEFAULT] se
Press any key to shutdown
[DEBUG] shutdown

I did as instructed and modified the ini file to only have the following:

[BOOTCTR9]
key_delay = 1000

[DEFAULT]
path = /luma/payloads/v2gw.bin

Your not going to get a lot of help regarding gw. esp when you just yap something redundant like that. Its best to either say what youre doing so actual help can be applied. or just stay quiet and move on with it.

Cool. I'm not obligated to offer any help, and I would say I was fairly polite, as I legitimately am curious as to why you'd want a Gateway and could perhaps show you alternatives that would not require buying one depending on what you meant to use it for. But you want to act like that? Alright then. Have fun.

 

[rickson]

with the following title setup, does it mean the luma sysnand can have the latest firmware 11.13+ and emunand on 11.2, for the gateway to work in harmony?

 

[SJWPURITAN]

Damn. I'm able to access GW 4.0b menu but when I boot gateway mode after inserting the red card, I get a "An error has occurred. Power Down" error message.

Using B9S.
Sysnand is 11.8
Emunand is 11.2 created via GodMode9
Emunand is set to Autoboot via Luma3DS config (v9.0).

 

[Arnold101]

i have 11.2.0.35 and works. when using gateway mode the text sys before the firmware disappear.
