    4.2.1, 3.10.01, SHSH blob saved only with iFaith

    Just got this phone used. I tried to do a factory reset. Green Poison didn't like this, and the phone got stuck in a reboot cycle. I put it in DFU and restored the custom 4.2.1 - still stuck in reboot cycle. Tried several times and nothing. The last time the phone stayed in DFU and wouldnt come out.

    I had to go out of town and when I got back the battery was dead (because it stayed in DFU mode the whole time - couldn't turn it off). Now when I plug into my PC, I get a "USB device not recognized message." I tried manually installing the USB driver as directed here to no avail. When I plug into the wall I get no screen display presumably because it is still in DFU.

    Now what!?

    Have you tried to trigger in recovery mode : Turn it off, while holding Home Button, plug iphone in until itunes cable logo appears.

    How can I turn it off? It seems to always reboot into DFU after holding home and power. Though I'm not 100% sure since there is nothing on the display.

    Forgot to mention, I might have used iReb or RecBoot incorrectly. Maybe that is causing my phone to not be recognized by USB?

    Still waiting for the battery to die so I can try holding the home button when plugging it in, though I'm not holding my breath.

    So I just plugged in my other iPhone (3gs) into my computer. I'm getting the same USB error, so I guess that is a good sign. But, I can't seem to get either to read properly even after reinstalling iTunes and drivers.

    iPhone cable was broken, using a new one. Also had to completely remove all iTune and apple software from my computer, reboot, and reinstall. One can find proper uninstall order here: Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7.

    Now my iPhone 3gs reads normally and the 4 is in recovery mode... now what?

    I had tried several times - always resulted in the infinite boot loop. Guess I will try some more unless someone has specific suggestions.

    Using a custom ISPW from iFaith gives me error 37. Will try TinyUmbrella/Sn0w later. Can I still do this method if my current SHSH and firmware are not stored in TU?

    Solved. Here is what I did in case someone needs help in the future.

    Restored to 4.3.3 using TinyUmbrella to preserve baseband. Directions are here.
    Then used Fix Recovery. Directions here.
