Thread: Downgrading 4.1 to 3.1.3 question.

    Default Downgrading 4.1 to 3.1.3 question.
    My iPhone 3Gs is currently running 4.1 with baseband 5.14.02.

    Now is there anyway to downgrade it to 3.1.3 again and unlock it?

    I downloaded TinyUmbrella and it looks like I have the SHSH saved from 3.1.3

    Just use TinyUmbrella to run the TSS Servers and downgrade back to 3.1.3. However, once you attain the 5.14.02 baseband, that cannot be downgraded. Even after you downgrade to 3.1.3, you'll still have the same baseband.

    You'll have to wait until the next unlock is released; hopefully around when 4.2 is out.
