Just wondering, what happens to your nnid once you setup a rednand? will it work as normal? or will we need to format sysnand in order to use the same nnid on rednand?I haven't heard of a sysNAND brick yet. Unless you are literally messing with sysNAND from iosuhax. You should be good to be honest. If you do brick, used Wii U's aren't that much.
