Well, i unban my 3DS, can use online+eshop, but can make a new nnid account in the 3DS. I delete my 3DS nnid from the Wii U, but that don't resolve the problem. Creating new nnid keep giving the same error: Error Code: 22-2812 You cannot access Nintendo Network services using this system. Please make a note of the error code and visit support.nintendo.com. --- --- Try to do a new nnid on the Wii U and linked to the 3DS, but in the end, gives the same error. Any solutions? Maybe if i can edit the nnid.save file on the pc with the data of my new nnid on the wiiu, the 3DS will let me use the friend list.
