Here's what I've tried so far with knowitall's help
Knowitall If you downgraded with IOS Downgrader then you have a cIOS installed. BTW, you might want to try installing the ios16. Then, you want to use the new cIOS_fix that can be found on this thread. After this, use cIOS Uninstaller. Next...
Alright I did all that and got my wii back to 3.2U, and now I wanna install wiigators 0.3 loader, but the cios installer thing keeps giving me trouble, the same error i got when i tried it with 3.3u. help!
Can't find any threads about this particular issue on GBAtemp or the wider intarwebz. Saw one video on YouTube that seemed relevant, but it was some dude with the same issue, no solutions offered in the comments. :/
