Now i have this wii on 4.0, i installed hbc and it went black screen, ergo doesn't load. the only channels that do not load are the Hbc and the mii channel. however my question is this. i found a mii channel wad and was wondering if i install this will it work, leaving me with a bad mii channel and a good one. also i can probably get hbc to work via bannerbomb of some sort,but was just curious about other ways to get mii channel working......updates and reformats by the way were useless.Could i possibly use a nand backup of my good wii and swap it with the nand backup of this wii? is there a way to encrypt it with the bad nand's key? i know alotta questions......any help would greatly be appreciated.
