I have been searching on the internet for ways to do this, but so far I have only come across the TimeMachine in .rar format which I can't use, and something about pandora batteries which I don't trust. So what I would really like is if somebody with any program or guide(that explains how to downgrade and if there is a program have a link for the download) to answer here or email me (whichever you prefer).
