Using a black wii with no gc support, I performed a NAND backup but somehow missed the part about needing priiloader. I successfully installed ios 36 and 236 but while attempting to install d2x cios the system froze, the controller became unresponsive and I was forced to turn the system off. Since then it has become locked in the health and safety warning page without a command prompt and will not respond to any commands associated with the maintenance mode, leaving it unplugged over night also had no affect.
