Well, for now all it can affect is emunand. The software actually has more functions but you can't damage your 3DS if you follow the instructions posted here.does this cfw stuff modify the actual 3ds at all or only the emunand?
if it does modify the actual 3ds, has anyone that can restore their nand tried to update after installing the mod? does the update still work like normal or does it brick/fail to install kind of like a bad wii u mod?
