This happened to me before because of cioscorp lol... can you download the old ios36 as a wad using nusdownloader and install it with wad manager? I think that's what I did.
I really just want to rid myself of cIOScorp and I was told to update my wii with wii update, but it gives me an error when I try to do that... what's the next best way to go about removing cIOScorp?
