Got my 360 last week and was prepping to sell my old xbox. Having played lots of games it has profiles on there and xbox live information (credit card numbers, etc) i wanted to make it nice and clean on the hard drive. So in my wisdom i formatted it without giving it a thought now it wont boot in to the Xbox dashboard. It can boot the X3 mod chip menu no probs. How can i get it back to the way it was? Thanks for any help....
