    I have bought a used iPhone 3gs, it was working fine when i bought it.
    When i came home it was boot looping in recovery mode.

    Then i googled about it and thought of installing and upgrading the ios.

    I currently dont know what is the ios version or the baseband because it is not letting me go past the recovery loop.

    I tried to install the official ios 5 but iTunes gave me errors like,

    1) 3194 (I updated host files and it was fixed)
    2) 1600 (Used iReb)

    And a few more errors, i also have tinyumbrella with me.

    I am all messed up with these things.

    Mostly my ios version is something like ios 3. I am sure its not greater than 3.

    Most of these softwares want you to have some shsh blobs, i dont know what they are and i cant save them because
    my phone isnt booting at all.

    Can anyone please guide me on how to install some version of iOs which can be unlocked and jailbroken,
    so atleast my phone is functional.

    Then i can like save my shsh and update to ios 5 or something.
    Also I have Windows 7 Ultimate x32

    Any help will be greatly appreciated folks.

    Plz help

    Have you tried restoring it to 4.1? Apple is still signing that specific firmware version for some reason. I had a 3Gs come in about 2 weeks ago that was doing the same exact thing. I could not get it to do a fresh restore to iOS 5. The only way I could get it going was to put it in DFU mode and restore to 4.1. After it was successfully running 4.1, I was able to update it to 5.0.1.

    I don't know why it worked for me but that's the only thing I could do to get it working. I've never had another phone do that before either. Try that and if it won't restore to that either, you may very well have a hardware issue.
