So I formatted it, but everything was on my sd card after the format? I just couldn't see the games that I installed before the format on my home menu. Logging in with my NNID worked , so now injecting back the nand backup.
Logging in inte shop worked, but I can't see my installed CIA's after putting back the backup? How can I do that?
the only thing that formatting in emunand removes is content in the Nintendo 3ds/randomletters and numbers folder that corresponds to your emunand.
which is why i told you to back up said nintendo 3ds folder and to put it back on the sd after the format.
you should be able to copy everything back over, overwriting existing files in the process.
