So, this problem has been happening with my homebrewed Wii for the past few months. Whenever I open the homebrew channel, it will either crash the Wii immediately or startup and look like it's loading and connecting to the internet, and then crashes. None of the homebrew channels that I've installed on the home screen load either. I have BootMii installed, not sure if it's on a boot2 though. The SD card is 8GB. The standard functions of the Wii work just fine, I just can't access the homebrew channel or any homebrew apps on the home screen. I'd like to get this fixed as soon as possible so I can have the experience of playing on an original Wii again.
