    Hi all. I am trying to fix a coworkers iphone. It is stuck in recovery. I thought I might be able to do so using my iTunes account. It downloads the software and then extracts it. And then I get this message. The iPhone "iPhone" could not be restored. An unknown error occurred (21). I believe the phone screwed up after downloading an iOS 7 update. Does anyone have any ideas on how to get it working again? Do I have to use her iTunes account on her PC? I also wonder if I can get it working by jail breaking it? Thanks in advance for any help.

    Have you tried this, while being plugged int hold in both buttons until the Plug Logo comes up and see if it will restore that way.
