iPhone not recognized by any computer after trying to restore
So I am here out of desperation. I received an iPhone 3g 8Gb model from a relative when they upgraded and had it jailbroken and running fine for several months. Recently went to restore it back to the default iOS software using itunes under Windows Vista and was only able to get partway through, there was an error at the very end, can't recall what it was unfortunately.
Since then, all I can see on the iPhone is the initial connect to itunes graphic but the phone is never recognized(shows up as unknown device even after ensuring the apple drivers are used for that device) after trying everything possible to ensure the correct drivers are installed and even trying several computers that recognize other iPhones. To complicate things even more the power button functionality is intermittent at best.
Seeing as I can't even get new software installed on the phone, I come to you seeking any advice on accessing this device through other means such as hardware hacking as I have access to university electronics equipment and am a electrical engineering major or perhaps some trouble shooting I could do. I would rather not spend any money sending it into Apple to fix this issue and appreciate any sort of advice you can offer. If you need more info please say so.
