I was running 4.2U and had the newest homebrew channel installed with priiloader 0.29. I hadn't touched my wii in a while but when I tried to play a new game I recieved a 002 error. I figured I needed some new ios and I read that the new homebrew channel can run on 4.3 so I changed my priiloader settings to allow me to update. I didn't update through the system menu but through the prompt it gave me when trying to read the disc. After the update, now I get a screen that reads "The system files are corrupted. Please refer to the Wii Operations Manual for help troubleshooting." I can still boot up using priiloader but I can't boot into the homebrew channel from it. Help is greatly appreciated.
