Is there a list of things that can brick your ds somewhere? lol someone should hop on that n get it stickied. Im curious myself. if youve set up the mset exploit to load gateway on a 9.0 n3ds would making a back up of the nand be bad then? like would the fact that the mset stuff is installed muff with the back up? lol im just thinking i havent backed my nand up in a while and im gna have to go looking for my most recent back up.
