    Exclamation iphone 1.1.2 modem firmware 04.03.13_g???
    Hello ppl,
    i accidentlly updated my phone to 1.1.2 and then later followed the following tutorial:

    Everything went right untill unlocking the phone using anysim 1.2.1.
    I also saw that my modem firmware had been changed to 04.03.13_G..
    I really cant understand what i should be doing. Searched alot of forum for 1.1.2 with 04.03.13_g modem firmware but couldn't find anything..

    Please let me know what i can do to fix or unlock or whether it can be unlocked in the first place..
    And also if can anyhow downgrade the firmware to what it was before.


    the phone was unlocked and running 1.1.1 and then performed an update.

    add the source to the, under unlocking tools select baseband downgrade, then put your phone in restore mode (hold the power and home button until the apple logo appears and just let go of the power button, you should still be holding the home button until you see the apple logo) restore the FW to 1.0.2, then restore the phone again to 1.1.1 and proceed to unlock using which ever anySIM program that works with the firmware you want to use, if you have any questions PM me
