    You must not be doing the count down right.

    Try this thread...

    I am assuming you have an Old Bootrom...

    3GS old bootrom custom 4.2.1 ipsw

    Look at post #3 for IPSW...

    And

    post #27 for how-to....

    Check your baseband with TinyUmbrella... It may already be baseband updated.

    I had issues until I used above.

    ALSO no other IPSW seamed to work apart form the one in post #3...
