i tried installing arm9loaderhax, but i always got the secret_sector.bin not found error, even though it was in the a9lh folder. all the files were in the right place. I tried updating to 11.4 and just wait for a new hack, but i got an error saying i couldn't update. I tried recovery mode, it failed. So i formatted my 3DS, still got the secret_sector.bin error. tried updating and recovery mode again, both failed. I can't play cartridge games on it anymore. Can someone please help me? Also, reinstalling and redownloading my files also failed.
