Hey everyone. My friend has been having a problem with his 3DS where it will boot to a black screen, as if the console is in Sleep Mode. I have access to Recovery Mode and updated it to 9.9. Even after that, its still booting to a black screen. On a side note, the 3DS is preowned and has been modded to have a Blue and Black shell. I'm thinking that either the 3DS died during an update(Though, it should've been fixed when I performed the update) or the NAND is is somehow damaged. All help is appreciated. Update: FIXED IT! Launched it into recovery to update(L+R+A+UP+Power On) then, I formatted the Home Menu(found this out by accident, L+R+X+UP+Power On), and then it booted back to the Home Menu, just like new! Nothing got formatted internally, all downloads were there, same FC, everything was there.
