    Happened to me. Be super careful cause it can get really hard to get out of restore mode. What happened to me is that it put the iphone in restore mode, then gave that error. Then it was stuck in restore mode and not recognizable by itunes. My suggestion if everything is still working for you is to just leave it at 1.1.1
