System transfer allows you to fully unban your console, and it should act like a regular functioning 3ds. If you dont do the system transfer, everything is fine, but you cant make an nnid. The same thing happens to the source 3ds after a system transfer.Optional is to do a system transfer. Is that required to unban? I would be getting my seed from an O3DSXL and I can't system transfer that to an N3DSXL. Thanks!
