@Bad_Ad84 no idea what a nand is but the wifi was working perfect prior to this, and I rarely use it. And the Wii actually powers on with the Wii remotes, so I don't think it's the bluetooth. And the light only goes once; I've never seen it blink twice. Serial number is LU301200260
Yes, I do have a gamecube controller and I've tried the savemiifrii method but I must be doing it wrong because nothing happens- is there a way to mod a controller to make it easier?
