This is the guide i followed
http://timashley.me/?q=node/6 everything was going fine, i had to download and install IOS35-64 v1040.wad due to a freeze when i tried to Downgrade IOS35 it then said i installed it already. When I got to the step where i ran WMIOS35 to install cIOS249 rev9.wad. I kept getting an error when trying to install it. So, then i switched to wad manager 1.4 to try and install it and i got the same problem. I figured it wasn't working because i had to downgrade. i ran cIOSdowngraderv1 downgraded was complete to 3.2u and thats the last time i saw my wii working.
