    Question Change CSC from XSG to MID

    Hello,
    Hope you all are doing well.

    I have a Samsung A51 that came with the MID firmware. When android 11 came out for Russia, I have decided to flash it and I did. Few days later, I have flashed the UAE firmware. Now, If I wanted to flash the MID firmware back (once android 11 is out for it) and since the XSG and the MID are part of the same multi-csc, which is OJM, will my CSC change back to MID or does it stay as XSG until I flash another multi-csc and come back again for the MID?

    Here is a screenshot of my A51:

    Just more thing, what does the XSG/XSG,XSG/MID actually mean?

    Btw, my device is not rooted and I have erased everything every time I have flashed.

    Thanks in Advance!

    Hi there

    You should not have flashed the Russian Android 11 firmware with not your Multi-CSC.

    Russia has Multi-CSC OXM, while the your device had Multi-CSC OJM (where MID is part of).

    As XSG (United Arab Emirates) is also part of Multi-CSC OJM, and when you flashed that firmware while your SIM-card was in your device, your device should have gone back to MID.
    Nut I see nothing has changed and is still XSG. I'm afraid, your device will stay at XSG and can't go back to MID anymore.

    Thanks a lot for the reply!
    I forgot to mention that my sim card was not in the device when I flashed back to the XSG. I have inserted it and it did change back to MID, Here is a picture:

    If possible, could you please explain what does XSG/XSG,MID/MID actually mean?
    As far as I know, the last MID stands for the original CSC of my device, but I don't know what the other codes mean.

    Thanks a lot!

    Have you put it in SIM-2? You've to put it in SIM-1 (but your device will RESET when you do it)

    XSG = Active CSC (United Arab Emirates)
    XSG = SIM-1 CSC (United Arab Emirates
    MID = SIM-2 CSC Iraq
    MID = Product-code Iraq

    Yep, I put it in SIM-2. After changing it to SIM-1, I got the following:

    So, the Active CSC is related to the firmware itself right? that is, it will only change if I flash a different CSC?
    And I assume the product code is original CSC the came with the device?

    Also, does it really make a difference whether I flash with the SIM card inserted or not?

    Thanks a ton!

    The first CSC will only change when you flash a different MULTI-CSC (NOT CSC from a different country).

    i.e. XSG & MID are both part in Multi-CSC OJM.

    The product-code is indeed the original CSC of your device.
