So my iPhone 5 develops a fault, within warranty, and Apple agree that it needs replacement. They tell me the best option is drive to an apple store and they will swap it out. So I wait a week for a genius appointment then drive for 2.5 hours to store and swap it out - then drive home for 2.5 hours. A long expensive trip, but so far so good... But when I get home I can't get any service. So, by the advice of Apple, I restore it. But then the problems start; its in recovery mode, but it won't restore. Throws up the error code -1. Even DFU mode (and yes I am in DFU mode with black screen) won't work. Apple won't help, they say I have to return it to them. So before I go insane, is the ANYTHING I can try to restore it? TIA.
