I have a LU64+ Wii with system menu 4.2. The Wii was semi-bricked while it was on system menu 4.1. I tried updating it to 4.2 to fix the problem, however it didn't do anything. When I try to load a channel, it just goes straight to a black screen. However, I can still run bannerbomb, so I can run whatever I'll need from there. How should I go about fixing this?
