Trying to help out my friend, he accidentally updated his wii and we're stuck on this one part. Everytime we try to change the revision to IOS15 to 0 we come across this error. Installing ticket... Setting the revision to 0... Error: ES_AddTitleStart returned -1035, maybe you need an updated downgrader Error: Could not set the revision to 0 Downgrade failed Press any button to exit... any help/ideas? I've tried the TBRs from http://gbatemp.net/index.php?download=7340 http://gbatemp.net/index.php?download=7305 and the simplistic guide, none work.
