    Default Please help me downgrade my iphone to 3.0
    I'm stuck here i downloaded wrong firmware for my Iphone 3gs it's called Golden Master 3.0 firmware build 7A341 for developers and now I am trying to downgrade it to regular 3.0 and I get an error in itunes that my phone isnt eligible for that firmware. And i dont want to install 3.1 on my 3gs cause i wont be able to unlock it. Please help me cause I'm really stuck here.

    This is what I did not read before installing the right software:
    This version of iPhone OS 3.0 should only be deployed on devices dedicated for iPhone OS 3.0 GM Seed software development
    . By installing iPhone OS 3.0 GM Seed software on your Authorized Test Devices, these Devices are permanently “locked” into testing mode and cannot be restored to an earlier release of iPhone OS. Bear this in mind before installing the software.

    The ONLY option as of right now for the 3G[S] is 3.1, until Saurik tells us how he downgraded. for now you are stuck.

    Sorry
    So long, and thanks for all the fish

    Yeah I guess I will have to wait until Saurik tells how to downgrade from 3.1 to 3.0. Thank you guys.

    Hi,
    I followed saurik's instructions to the "T" here's how I did it. BTW - I'm using Vista
    Computer-CWindows\System32\drivers\etc\hosts. Well, here's the problem when I get to hosts HOW do I add and WHERE? THE 74.208.105.171 gs.apple.com according to saurik. Please I hope someone can help me. Thank you.

    Code:
    ipconfig/flushdns
    If you just tried updating before adding in the entry in your host file.

    HTH

    Icehacker,

    Thanks for the reply. However when I try to type in the ipconfig/flushdns per your instructions, a box would pop up as quickly as it's gone. Could you please give me a step by step guide on how to apply the information from saurik. Thanks again.
