a friend asked me to do his wii and it was a lu70 also it was running 4.0 . now i used simplisticmod to hack it . i updated to 4.2 like it said to, the only problem im having is all back up loaders are freezing.emulators and other dols work fine. im woundering if this is a lu70 problem or a combo of lu70 and 4.2
