    I've heard that there's a way to downgrade a Wii thats 4.0U if you have only the Homebrew Channel installed. But how? I've searched everywhere but I can't find it.

    You also need a cIOS.

    Is cIOS downloaded onto the Wii or is it just some program on the SD card? And if it's downloaded on the Wii can it work on 4.0U?

    You can search on you tube. They got tutorial videos. I downgrade my 4.0U to 3.2U.
    But remember, all steps need to be done without errors. If you got any error, just try until you got the process work...

    I stopped on step 10 though, and ran some homebrew (WiiSCU among others) to add truscha sign-bug back into a lot of IOSes.
