  1. My smartphone(SM-J200F) Developer options and OEM unlock are disable,
    and i did flash it already and now it is blocked and shows FRP error.

    • Flash the ROM with stock firmware and then Root again. Never disable developer options and OEM unlock after root it.

  2. Thank you for your attention,
    I want to flash it but Odin shows this error:

    File analysis..
    Get PIT for mapping..
    Firmware update start..
    NAND Write Start!!

    Complete(Write) operation failed.
    All threads completed. (succeed 0 / failed 1)

    and unfortunately one more thing :
    Samsung Kies and Smart Switch do not support my smartphone!
    I do not think anybody have been had these problems Together !.

    • Download the firmware that match with your model number : SM-J200F from sammobile dot com then flash the ROM

    • Try to use other firmware update, I think the firmware does not compatible with your hardware. If you sure your model number is SM-J710FN, try download other firmware from sammobile website. There are many date update try to use old date update of the firmware.
