    I was playing to know how can I lock my bootloader on my mi6 by those command : fastboot oem lock and I end up with this message in boucle when the phone start : the system have been destroyed ! I can't do get to the recovery. Just on fastboot mode but unlocked. I have try all my effort to flash and I fail. I bring it to chinese shop outside and no one still can't make it. Lucky that I'm China and can get to the Xiaomi official repair store to Fixe it for free. So be carefully friends

    No with miflash you can reinstall your ROM and after the installation he blocks the bootloader if you want, there is a command called flash and lock

    fastboot oem lock
    this is the locking command from the script.
    See it for your device first, before using it.

    After some reading on EN.Miui's forum, there's a post mentioning that relocking bootloader is ****ONLY safe, IF stock recovery is installed**** (no custom recovery like TWRP). Is this true?

    How to do it ? I mean to stock recovery and the room ? On the mi6 it's completely block the cellphone of showing that the system have been destroyed. Can't flash it with miflash and can't unlock it.

    You can try to flash it via Chinese Mi PC suite.
    And there is nothing to lose if you try to unlock it via "fastboo oem unlock-go".
    Wait for another opinion for this method, before try.

    Another try is with engineer cable or button combination to enter in EDL Mode to flash the phone

    I already flashed back to stock ROM & stock recovery; what is the next step to re-lock the bootloader? 'Fastboot oem lock'?
