When I try to download apps from the Homebrew channel it freezes and I have to shut down the wii. I've tried formatting the system and reinstalling it, but it didn't work. I have a 4.2U wii. I used bannerbomb to install hombrew. I didn't need to usethe Twilight hack or any other form of hack. I just installed it fromt the SD card. There are other problems I'm having, but I'll start with this.
