Thread: "Bricked" 1.0.2 PLEASE HELP!!

    Default "Bricked" 1.0.2 PLEASE HELP!!
    Hey guys,

    I posted on here last night on this same issue- I still havent figured it out.

    Basically, i get the activation screen with an error message that says "Incorrect SIM- Insert an unlocked and valid sim to activate phone"

    It says I have Version: 1.0.2 (1C28)

    Firmware: 04.02.13_G


    I am an AT&T customer, but i unlocked or jailbroke the phone when i first got it to add other applications. Then I accidentally updated it through itunes and it made it inoperable...

    I really can't seem to figure out what I have to do, if anyone can help me out i would really really appreciate it.

    Default Lower the Baseband
    Your going to need to use Mobile Terminal and lower(flash) the baseband(modem firmware) from 04.02.13_G to 3.14.08_G.

    Use this guide. I used and it works perfect.

    Once you lower the baseband. Your SIM card will work.

    I would recommend reading Step 2.
