Tutorial  Updated

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.

Okay, I more or less followed this so I have the way to load Gateway for A9 from 4.1b. I see now that they finally released 4.2b for handling system 11.1.

What, if anything, from the GW 4.2b files to I need to update on my O3DS XL to reap its benefits? Just the launcher.dat? Or is there anything more I should concern myself with?

You should only need the updated Launcher.dat. Also, keep in mind to not update in GW Mode on a SysNAND-Only setup, if you have an EmuNAND, then you should be good to update regardless of whether you use Luma3DS or Gateway, just make sure that on an EmuNAND setup, that you are actually updating the EmuNAND and not SysNAND in GW-Mode.

Anyone found how to go directly into Gateway mode, using the A9LHAX with LUMA 3DS on 11.1, using 3.7.1 on 11.0 you could acces just using one direction key. Now you need a direction key and L, R or Select once it goes into a gateway menu that asks if you want to go into GATEWAY FASTBOOT mode on Sysnad. I have no emunand, just sys9nand.

Been away for 8months now and was only doing gateway cart for the past 2 years.

I dont think you can with their 11.1 launchers now unless I missed something too.

Cenk Akbaba, both 4.2b and 3.7.2b are the same, sadly, since the 3.7 version allowed you to use just one direction payload command to go direclty into gateway mode on 11.0. Sadly, on 11.1 you still have to go into that menu you state. Dunno why are you having this black screen issue. Actually you dont need to press all button, but one, well al least it works for me, selct, l or r. Hope we have a solution for this, I manage to send an email to Gateway for a 3.71 version that can go into the menu directly, hope many sum to the cause.

Thank you for the guide.
I revived my Gateway 3ds. I have a lot of .3ds games from glorious days.

But sad i can't use both of arm9 and gateway. Because i cant take risk to update sysnand while in gw mode.

Should be a way to use the red cart while luma3ds. Its so boring to boot gw mode always when i want to use My Gw

You have to press one button to boot into GW mode. What's boring about that? LOL

@Temptress Cerise @Hayleia

good day, just want to ask some questions cuz i cant go to gateway menu using GW 4.1/4.2...

my current set up is:
-no init a9lh
-luma 6.3.1 auto boot sysnand (emunand hold L on boot)
-gateway enabler = luma/payload/y_v2gw.bin
-gateway a9lh payload = luma/payload/gateway.bin
-gateway 4.0 = root/launcherdat.bin

my settings above:
pressing y + power button brings me to red dragon GW logo
A. without pressing L on red dragon - boot to emunand
B. while pressing L on red dragon- brings me to Gateway Menu...

BUT ON 4.1/4.2
A. without pressing L - boot to emunand
B. while pressing L - boot to emunand
How can i go to Gateway Menu on my setup if i use 4.1/4.2?

With 4.1 and 4.2, you have to press L and SELECT to access the Gateway menu, not just L.

From GW's website, about 4.1:
From now on, any system installed with GATEWAY FASTBOOT (formerly known as `A9LH’) will require holding down L+select in order to get to the GATEWAY menu. This is to prevent the younger users of our system from accidentically triggering unintended actions from the GATEWAY menu. (Think of format emunand and such)

I am not really aware of any guide's to it. You'll just need to find that donor secureinfo file on that iso site. If that's still doesn't make sense tho, then yeah, you'd need to undo your region change and revert back to use Gateway.

I came to believe donor file is not needed as we can already edit the secureinfo using GodMode9 and so I not quit sure where the problem lies since I tried using both region of EUR and JPN anyways I ended up just flashing my old SYSJPN NAND and be happy with it...thanks for all the help maybe some guide will pop up after weeks or so that I can follow through as I really wanted a N3DS with english language... :) cheers mate

You can use edited SecureInfo only with Luma or other scene CFW, but not with Gateway.
By editing SecureInfo you break its signature and Gateway doesn't patch signature checks for it.

Exactly what redunka said. Gateway doesn't do any patching at all on the SecureInfo file, because it doesn't do patching on it, then the signature breaks if it has been edited and you will black screen. Luma3DS does do the necessary patching if has been edited and because it does, you will boot fine. Because of this functionality when it comes to Luma3DS, is why the Region Changing Guide on Plailect's Guide tells you to do this, it assumes you will only ever be using Luma3DS.

Alright, guide updated, finally. Sorry, real life is a real bee word.

Black Screen After Dragon Logo after following this guide section has been updated with actual steps. Since, those links keep getting changed//updated//moved, and it's tiring keep up with whatever//wherever the new links move to lol, so hopefully with those steps added, it's less messy for people to look for that info.

New button commands to boot into GW Mode has also been mentioned.
