    hi, I have done everything as it was said, however there is nothing on my Iphone, I get the message Done at the end but there is no data streaming on my iphone. as it was shown in video. What is next?

  • Missholsinger says:

    I did all of these instructions just like they were written and my phone goes through the whole process and then at the end ends on the recovery mode screen. I cannot get it off recovery even when I re-do the process it still always goes back to the recovery screen and when I sync it with itunes, itunes wont restore with custom or factory ipsw. Any solutions to this problem? I have heard a lot of people are having the stuck in recovery mode just like me and cannot get out, But I have not heard of any or tried any solutions that actually help or fix it. Thanks

    I did this and it worked great except my battery was draining constantly, constant data usage, and overheating. The fix involves using SAM to create a virtual SIM that will spoof iTunes so it will activate properly and not drain your battery: http://ideavein.com/2010/12/28/fix-battery-drain-gps-iphone/
