I am helping my friend play the new super mario bros. I updated his wii to 4.2u but during the process the screen went upside down. I reloaded iso36 from nintendo and than preceded to finish updating to 4.2. I than installed cioscorp 3.5. I had no problems but the wii programs would occasionally lock up. Than i installed rev 15 and than downgraded to 4.1. When i tried to install preloader .29 it would get an error message and won't install. I tried to virginize by upgrading back to 4.2 but now nothing works. Homebrew works and i can play new super mario bros but a bunch of homebrew apps won't load. Truchna bug won't work and wad manager 1.5 won't run in 249. I can't downgrade back to 4.1 or modify 4.2. Can somebody help me
