Hacking 2DSaver (Beta) - Fix your 2DS format brick - Testers needed

[heiyu04]

Here is how to fix the 3D slider brick using ntrboot without doing a full ctrtransfer:
A second working 3DS is needed, or you can have someone dump the file in step 1-3 from their console and share it. Would this file be allowed to post here? If so it could be added to the instructions. Should be fine, right? It's just system config savedata.

Instructions

1. Load GodMode9 on the working console from ntrboot/B9S
2. From the root GodMode9 menu, navigate to [1:] SYSNAND CTRNAND -> data -> {a folder with random numbers} -> sysdata -> 00010017
3. Select 00000000, then select Copy to 0:/gm9/out
4. Press START+R to power off the 3DS and copy this file to the SD card in the bricked console
5. Load GodMode9 on the bricked console
6. Navigate to [0: ] SDCARD and find the file you copied
7. Press Y on the file to copy it
8. Back out until you are back at the main screen and again navigate to [1:] SYSNAND CTRNAND -> data -> {a folder with random numbers} -> sysdata -> 00010017
9. Press Y again to paste and unlock writing according to the onscreen instructions, relock when done
10. Press A on the file you just copied and select Calculate CMAC
    
11. Press START to reboot
12. Go in System Settings and change anything that's wrong such as birthday, nickname etc. since the settings will be cloned from the working console.
13. ( ͡° ͜ʖ ͡°)

Thanks to @TurdPooCharger for testing the steps to make sure they work and for pointing out that you also need to fix the CMAC.

According to your steps, all of them are cloned except WiFi. Isn't WiFi information stored in this file

It didn't say that anywhere in the steps. I don't know the answer to your question, though.

hi,
I just found my old 2ds stuck in 2017 on 3d calibration and today I decided to buy the cubic ninja card to unlock it, hoping that this works, once unlocked how can I get the screen back to normal and no more stretched? then I read that by updating the console you can run into another brick regarding the black screen, so how do I update the console? I would like to point out that I don't have the nand backup and that I lost the sd card with the modification so do I have to start again with another sd? Im sorry for the english and I wait your reply. Thank you

2DSaver appears to no longer be working. On my OG 3DS I see this error:

"2DSaver - zoogie ( luma)
configInit: 00000000
getConfig: res-00000000 val-00010001

Press A to fix 3d slider brick, START to exit

getConfig: res-00000000 val-00010001
There's a time and a place for config modding, but not now."

Some notes:
- I'm using Luma 13.2
- I noticed in the 2D slider's latest release, the config.ini has the incorrect titleid for hbldr_3dsx_titleid:

;2DSaver options
;USA
hbldr_3dsx_titleid = 0004001000021000

The homebrew launcher titleid is 000400000D921E00

I tried updating that value in the config.ini but still see the same issue. I also noticed the guide says 2DSaver will appear automatically when you restart the 3DS, but it only appears when Homebrew Launcher is launched. Setting Homebrew Launcher for autoboot also didn't help resolve the issue.

Any ideas?
