I have a 4.2U modded wii that I didn't back up the NAND on. I just got a game cube controller today and wanted to create a backup. I tried launching the BootMii from the Homebrew Channel but just got a black screen.
So in my infinate wisdom if figured I would Erase the Homebrew Channel and just re-install it from the SD...
Problem is that now whenever I attempt to go to the SD card, the Wii freezes and I have to reboot.
Any ideas on what I should do next would be greatly appreciated.
So I managed to get everything back and functioning by using the SD Card Icon instead of through Data Management. I think I may have had Bootmii installed both as boot2 and IOS before...all good now though just as IOS.
