    raman0424, Apr 17, 2019 :
    After performing the fastboot command to lock the oem its showing done on cmd and even on my phone it's showing the warning screen where we have to select Yes and No to lock the bootloader.

    I select the Yes option were it say lock the bootloader and restart the phone.

    My phone restart but when i go in developer option it's showing me OEM is Unlocked and the option is grey.
    Everytime i restart my phone its showing me the warning screen of OEM is unlocked.

    I'm on stock rom and stock recovery

    Need Help.

    Thanks in advance

    Never run the ADB command to relock your bootloader on a OnePlus device. So many things could go wrong. Best thing to do is run the MSM Download tool and it'll flash it back to full stock for you

    Follow the guide step by step and remember that you're doing this at your own risk. Don't forget to back up your device first

    Thanks for the tag.

    Hitting the MSM tool already? Looks like that's a straight jump. Let me know if you still need help with this.

    Can you say what's the command you're running to lock bootloader?

    "fastboot oem lock" this is the right command to relock your bootloader.

    You've hit the right spot! No idea as to why it doesn't work.

    Try this once

    Factory reset device
    Flash stock recovery
    Reboot system
    Boot to bootloader
    Lock boot loader - "fastboot oem lock"
    Reboot with "fastboot reboot"

    Check if bootloader is locked or not

    In TWRP go to the mount section and make sure the "mount system partition read-only" option is ticked

    Flash oxygenos and reboot

    Wait for it to fully boot

    Now check if your recovery was replaced by oxygenos recovery

    After that lock the bootloader

    You can only lock the bootloader if both the boot and recovery partition contain a signed image which is signed with the same key
