Freezing indicates that you don't have the cIOS you're trying to load.
Go HERE, and install cIOS249 with a base of 56.
pretty new to the wiihacks scene, so obviously not very experienced.
I've been using usb loader gx latest version fine for about a week or so, then today it seems to keep freezing on startup when trying to load cIOS 249.
Will I have to update this IOS? If so can someone point me in the direction of how to do that?
thanks, sorted it
