Also do you see any present icons on your home menu? Sometimes they might end up in that present state for whatever reason.

Unless you have unlinked your nandsDONT DO THIS IN SYSNAND. IT WILL DELETE ALL OF YOUR GAMES IF THEY ARE DOWNLOADED FROM THE INTERNET.
Good point. Still not a good idea lol.Unless you have unlinked your nands
