    Change firmware country CHN to XEF ?

    Hello,

    I will need your help to change firmware to another region.

    The motherboard of my SM-T820 tablet failed and I replaced it with a new motherboard but I did not notice that the new motherboard was on Chinese firmware (T820ZCU3CTD1, CSC: CHN) and would like to put the firmware of my region (T820XXU3CTD5, CSC: XEF)

    So I download the firmware T820XXU3CTD5, Odin 3.14.4 but the flash does not want to do this, error message on the tablet and on Odin.

    How can I change the firmware for another region?

    Hi there

    You can't flash French firmware (XEF) on a Chinese device.

    Great, thanks for your reply.

    Do you think flashing a custom ROM might solve my problem?
    To have all the google services and have a tablet entirely in French.
    Currently, the play store is very limited and some applications are in Chinese, even when downloading APKs from apkmirror.

    That I don't know, because we don't support ROOT and/or Custom ROM's

    Thank you for your response and help

    I will already try to fix the missing "oem unlock" in "Developer options", but for now after trying several methods that I found on the net, I cannot find the right method.
