Did you backup your saves with Checkpoint and/or JKSM? → Easy restore
Else, in case your SD data is still intact and you have access to your
movable.sed you can decrypt them (and re-encrypt for the new device).
Getting movable.sed:
- The one you got from the bruteforce service if you used a *miner method for installing B9S should contain the key.
- The embedded essentials.exefs in a NAND-backup created with GodMode9 contains movable.sed (gives the embedded version is up to date)
Use ninfs for accessing the data.
Good luck!
