Hello, my 3DS is soft bricked. I modded my old 3DS till eventually I booted up the 3DS's GBA mode one day and then when it loads into the 3DS home menu, it doesn't work, it would show just black and the Rosalina menu, Luma and godemode9 would work, I tried every solution I could find, I didn't care about all my files going missing so when I found a guide that explained how to recover a 3DS when every single file was gone, I figured I could just delete a lot and start from scratch because at least then I wouldn't be looking for what the problem is, and instead taking a different approach. That didn't work out so well, and at this point I've tried everything I could from research, I loaded up saftB9SInstaller several times and many times it didn't work but eventually I fixed that part, I got CTR transfer and used it several times, doesn't work. When it could still load the Rosalia menu I put in the combinations for the 3DS's safe mode and let the normal software update, it actually showed something boot that was from Nintendo for a bit, but the update didn't work. One person has said to mount the CTR transfer tool and copy the files in it to 1: sysnand CTRNAND, that at least fixed the fact that almost all the files from there were gone. I know should be able to recover my 3DS, I still have perfectly saved files of my Movable.SEd, SecureInfo_A and LocalFriendCodeSeed_B. So from what I understand as long as I have those, it's still possible to fix it. I also heard that selecting Godmode9's "fix CMACs for drive" option can likely fix a problem, that didn't work as well. As of right now, if I let the 3DS boot into it's native menu, it will show:
"An Exception occurred
processor: Arm9
Exception type: data abort"
And then a lot of what looks like Hex code. That error was supposed to be fixed by at least something I had done so far according to a few guides I followed.
If anyone can help me recover my 3DS's ability open the home menu I would deeply appreciate it.
