Hello! My friend was on his 3DS that I exploited for him, he went to an FTP app on the home menu to transfer a .cia, then he held the power button down to force shut-off while in the app. Now he boots into a black screen! So I told him to restore the NANDmin.bin that I made during the guide, he did that and there is still a black screen when he boots up! I am kinda worried, as I don't know if it may be a hardware issue. His camera didn't work before this happened either. What can I do to help him? Thanks!
