  1. My phone shows me:

    AP: I747UCALG1
    CP: I747UCLG1
    SCS:I747ATTALG1

    Is this update going to brick my phone or something? Can’t find that answer anywhere.
    It’s indeed a SGH-I747 AT&T, but I’m worried about that SCS code as I’m going to use Odin to flash.

    1. If you are in the United States then you can manually upgrade thru Kies.
      If you are outside U.S regions, then you have no choice but manually upgrade via Odin.
      Odin will not brick your phone since it’s the software used to fix bricked Samsung devices.

  2. i have unlocked my phone unofficially and rooted it to have CM10.1 on it … now if i revert back to stock will thr be a chance of getting my phone locked

    1. I rebooted in update mode (Volume up + Home + Power) and did Wipe Factory Reset. Than I reboot again and it worked fine.
