    Default Downgrade 1.1.2 OTB to 1.0.2 ??????

    Hello,
    I bought a China 3Gpp sim to unlock an US 1.1.2 OTB but in the instructions it says it is needed to downgrade to 1.0.2

    I tried to restore 1.1.2 to 1.0.2 and get Error 1 (it can't restore).

    Then downgraded to 1.1.1 and tried to restore to 1.0.2 and still get Error 1 (it can't restore).

    How can I downgrade to 1.0.2 and why it's needed to do this ?

    The Sim I purchased is http://cgi.ebay.es/ws/eBayISAPI.dll?...MEWN:IT&ih=017

    THANKS!!!

    you don't have to downgrade to 1.0.2 in order to make the sim work, you just have to restore the phone to 1.1.1, then jailbreak and upgrade to 1.1.2, also you have to jailbreak this one and then insert you sim and it should work.

    What would happen if you put your sim and the 3Gpp sim in before you start the process?
