i want to downgrade cause my smash mods crash on 11.4 and my little brother updated it not knowing he is autistic and 3 years old so i doubt he knew what he was doingif you have A9LH you wont need to downgrade. did your brother really update it, or do you not want to admit it was you?
thanksrestoring your nand is safe no matter what firmware you are on. As long as the nand backup is from the same console and is not corrupted. Although you may need to reinstall the tickets to any new games you added since the backup
It is safe to update anyway on a9lh
