I just want know if there is a way to downgrade 3ds firmware 10.5 to 9.2. I tried using sysUpdater and it keeps saying "failed to get CIA file info. I just want to restore my NAND from gateway (only works on 9.2) because my nnid doesn't want to work (error 022-2634)...as of this time i dont have either sysnand or emunand, my sd got corrupted, got a new one and im left with 3ds 10.5 (my games and save files are sill here) :/
