So the other day, I hacked a friend of mine's 3DS using a DSI downgrade. Once I installed A9LH, I formatted his 3DS (Which had my nintendo account because of the system transfer) and reinstalled a backed up nand that i made on my 3DS (The source 3DS). However, after doing this, I can no longer access the eshop like i could before the system transfer. When i check system setting and go to my ID settings, i get the error listed in the title. Does anyone know how to fix this?
