So I have a 3.2U softmodded wii. I would like to update to 4.0U so I can have the SD channel. I modded this Wii a long time ago with the Twilight Hack, and now want to update it so I can play ISO's off of my hdd and such. Can someone point me in the best direction from here please. I have the HBC and everything already installed from over two years ago. Thanks!
