    i am trying to jb a 3gs running 3.1.2/05.11.07 (simlocked, never jailbroken before) using custom firmware. i've downloaded iPhone2,1_3.1.2_7D11_Custom_Restore.ipsw, but whenever i try to restore it, i get 16xx errors from itunes (mostly 1604).
    i get these errors in dfu or recovery mode, too.
    ireb does not work.
    what am i doing wrong? is blackra1n the only option for 3.1.2?

    You need to use Blackra1n or already be jailbroken or use PwnageTool.

    why do i need pwnagetool if i can just download the custom ipsw off the internet (e.g. from iphonefix.de)? isn't it the same? i haven't got a mac nearby.

    You need to use pwnage if as you´ve never JB before... The first time it uploads a custom payload so that you can use pwned IPSW´s...

    For a 3GS, you can only restore to a custom firmware if you're already jailbroken. As you're not, and you're on stock 3.1.2, you won't be able to restore to a custom firmware.

    Instead, as mentioned above, blackra1n is your best bet, which should jailbreak your phone without having to restore to anything. This will run on Windows.

    I had a hell of a time trying to JB a 3Gs with the custom firmware.

    I restored to 3.1.2 then JB using Blackra1n and after that went back and restored/JB with the custom firmware without any 16XX errors.
