awesome. This is exactly what we needed to see. Nice work.
that is the correct way to make a backup.
this is the correct way to move your backup to the restore folder
This should have worked. It seems your backup might not be good.
One thing we can try is to use
EmuTool on your PC to copy your partition based emunand to a files based Emunand so you can copy it off your old SDcard to your new SDCard as regular files and then use Hekate to switch over to a files based emunand to see if we can get it to work. You will be able to swap back to partition based emunand by just reversing the steps in Hekate. It’s a long shot but we might get lucky. If it works we can use
JKSV to dump your saves, switch back to partition based emunand then use JKSV to import your saves back to the fresh emunand partition you just made. A bit of work for sure. You will still have to reinstall your games again but at least you would have your saves.
Another way would be to simply use
NXNandManager on your PC to dump the game saves from the USER/saves partition. You will need to dump your prod.keys using
Lockpick_RCM to enable the yellow explorer folder so you can browse the mounted USER partition. You would reinstall your games and import them with
JKSV just the same but with fewer steps.
