So i accidentally upgraded my system, here's the short story: I left my o3DS on my bed, right? Okay, I had powered up my system, and every once and a while it will notify me that there is a new update. My cat activated the update, and yeah. I am not joking, I am angry with my cat. I still have old sysnand and emunand backups, as well as normal NAND.bin backups, is there a way i can restore those on my system?? *No hardmod suggestions please, I am going for a vanilla structure for my system.
