Using Luma3DS + Gateway on B9S


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:
    Code:
    [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:

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.

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.

thats the one you wanted you should be able to use this guide now to setup gateway on your emunand

--------------------- MERGED ---------------------------

actually wait you should unlink your emunand from your sysnand first . . . (format one or the other)

boot into emuNAND then format it like I would as if I were just normally formatting a 3ds?

I screwed it up somehow. I booted into emuNAND but somehow formatted my sysNAND. The settings menu differentiates between sys and emu now but I lost luma3ds and fbi tiles on the homescreen, does that matter?

**edit**I can still access luma3DS and godmode on launch

you can use rosilina to reinstall fbi (but you dont need it installed you can use it via rosilina if you so choose)

I can boot gateway mode now, it shows the gateway logo, but the card doesn't show up... if I boot GW mode without the card it tells me to insert it to boot GW mode, so the card works. The SD card shows up on my computer and shows the files on it as they were the last time I used it. I can press select to choose the game for the cartridge and it reads the games on it but when I select one it doesn't do anything.
there was a couple things that were slightly different:
the version of BootCTR9 the tutorial pointed to me is named differently than it is referred to in the tutorial,
and it said to use the latest GW launcher.dat, so there was no specific version
I had to select the game a few times before it loaded, but it finally worked.
I can't thank you enough for your help! :)

**edit** I've run into some trouble again. Whenever I try to load a game from gateway the system crashes. default 3ds error has occurred screen.

i am sorry i only have a limited knowledge base when it comes to gateway my honest advice would be to (ditch gateway) try re-downloading the files from this guide and replacing them on your sd card

after installing a game via .cia it worked perfectly. not sure why but I figured I'd mention it in case anyone else is ever having the same issue.

Thanks again for all your help, and thank you to anyone else who helped along the lines.

What game was it? Are you on 11.2 EmuNAND?

would you like a japaneese emunand for gateway or usa . . . if usa then do what i said above . . . if japaneese then you will need to downgrade your emunand to 11.2 . . . but either way to use a gateway you need a 11.2 emunand

If he has 11.8 that means he's already patched it as a frankenfirmware. I think what he may need to do is follow this guide, create a new emuNAND from US sysNAND, update it to 11.8 as frankenware, then inject his jap emuNAND backup into it.

Another option would be repatching sysNAND back to JAP (or restoring from backup), create JAP emuNAND and patch as frankenware, inject his emuNAND backup to it again, then repatch sysNAND back to US.

I'm not certain if any of that would work however since I don't have experience with multi-region NAND's.

i have gateway booting along side my luma cfw. if i boot into gateway mode i can press select and boot the games off the card but no online play. and if i let the system boot regular it boots into luma sys 11.9. Think of it as a dual boot but the only reason is to be able to launch the gateway games on the red card. otherwise the card is useless. i followed some guides online and got it running smooth on two systems i bought the 60 dollar gateway card for. id hate to throw them away. serves as a space to store some games???? at the cost of a 1gb emunand on your sd card you get the gateway mode. i can vouch it works. do it if you got a card laying around and want to just mess around. otherwise.... luma on your sd card. hit install and let the sucker sit overnight.

Hello! I am new here. So yesterday I somehow managed to accidentally wiped my gateway entrypoint (DS profile exploit) and have no way to access emunand now nor have the way to use the gateway red card.
I have an 8.1.0-0J sysnand new 3ds with 9.3 emunand before. Unlinked.
Its been years since I've last paid any attention to 3ds hacking scene.

My question is
is it possible to downgrade from 11.9?
if i want to use the inscripted AIO, what is the steps required for 8.1 sysnand?
