recently i was installing arm 9 loader hax to get luma and fbi on my n3ds. i got the failed to mount ctrnand error and then, backed that copy up over my good sysnand backup. and after finally fixing the system by installing 9.2 and updating to 11.2, i realized that some of my downloads were corrupted. but with a quick reinstall they were fixed no problem. my sound app also would crash upon loading the contents of the sd card, but if i remove said sd card before opening up 3ds sound it works fine. also face raiders and 3ds camera (full and lite) crash upon opening. would a system format fix this, or should i restore my backup of 9.2 and update again? its not a big deal that its gone but its a sense of incompleteness, ANY HELP?
