    Unhappy iPhone 3GS update problem
    Guys..got a problem with my Iphone 3gs 16gb

    I updated my iphone 3gs 3.1.3 with the apple standard firmware from Itunes (by mistake). I checked the phone and it is running on old bootroom, but am now unable to update the phone to 4.0(custom firmware) or again update it with custom firmware 3.1.3. I am getting the error 1604 and at times 1603. I tried it in recovery mode but still get the same problem. I did my best to get it to dfu mode but i was unable to go ahead.

    Please help me guys..i am really stuck with this...

    To my knowledge, you cannot upgrade a 3Gs from stock 3.1.3 to iOS 4 custom jailbroken firmware until you have jailbroken your 3.1.3 with Spirit, then followed these steps: IOS 4 jaibreak for Spirit users with old bootroom

    I had to do those steps myself, because I was in the same situation as you.
    iPhone 3Gs, old bootrom, stock 3.1.3.

    Jailbreak your phone with Spirit first. Spirit Jailbreak Fix for iTunes 9.2 on iOS 3.1.3 and iOS 3.2 | Redmond Pie
