I have an iPhone 3G 8GB. It is not Jailbroken or Unlocked. Basically the iPhone was accidently run down to 0. Then when I came to turn if back on it wouldn't. Basically, if I plug in a connector cable that is connected to a USB the silver Apple logo appears on screen for a minute or so, then the display disappears apart from a very faint Apple logo (almost like screen burn) until I unplug the cable, and it disappears completely. By the way, this is the only way I can get any responce from the iPhone If I try and put it into DFU mode, it comes up with the Connect to iTunes graphic. I connect to iTunes, iTunes recognizes a device is in DFU mode. I try and restore but it fails instantly with an Error 23. It then disconnects itself. I have this procedure of three different Macs, all with the same outcome. Anyone have any ideas? Is this iPhone completely dead? Is there anything else I can try?
