Or, join the 'hitting a nail with Mjolnir' fellowship, and follow the debricking stuff to downgrade to 4.0.x.
Thanks for the clarification, I'm a bit of a noob to this kind of stuff and probably shouldn't have used such a complex method in the first place like you said. I'll try the methods you suggested if I can work out how to do them :P
