I switch on my wii and i just get a black screen, the health & safety screen does not even appear. This happened after installing wii update for wii sports game. I don't have bootmill or preloader installed. I have try savemiifriii but it doesn't seem to work, all i get is a black screen with no version number at all. I don't have a modchip install yet. Is there any possible way to get it to work again.
