I have a brother in law who serves in the military, well about a year ago he bought a Wii while on tour, and it's a Korean Wii that was hacked.

Well apparently it wasn't properly protected . There were no nand or keys came with it. Well he went to try a newer game in it and it asked for an update, so he did so.

Well I tried to do the gamecube controller trick, and it showed 4.3U down at the bottom, so I am assuming it's been updated to that SM. But now of course it's only showing black screen, anyone know how to fix this?
