Not at all. Backups are only in emergency should something bad happen to you Sysnand. As long as your Sysnand is bootable we can make as many copies as we want for Emunand. Game saves are the only things we really care about. Games are likely corrupted and homebrew is relatively easy to recover with the homebrew App Store.Yes I agree I just backed up and will be reformatting the sd and starting over. I think you’re right it’s corrupted. Do you know if I have to do anything else before setting up again, other than formatting? My switch is banned, so I orginally set it up on sysnand instead of emunand. I have my backups of the sysnand (pre cfw), but I don’t think I need To restore them right now, right?
e: if your SDCard is large you will need Rufus or another 3rd party FAT32 formatter.
