Hope someone can help, I have just bought a second hand Zenfone 8 and on bootup I noticed that the bootloader has been unlocked, as I have no intention to root my phone I wanted to know if anyone knows of an easy(ish) way to re lock the bootloader?, any help will be greatly appreciated.

    The bootloader can be relocked, you will gain most of the features back (except the automatic updates, you will need to download the file manually from the zenfone 8 support page, Bios and firmware tab) then move that file to the phone's "internal storage". Reboot, then wait a few minutes, it should prompt you to update to a newer firmware.


    To relock the bootloader, here is what you need to do:

    MAKE SURE YOU ARE ON THE STOCK ASUS FIRMWARE BEFORE PROCEEDING

    Plug in your phone to a computer

    Open a command prompt/Terminal

    type:

    adb reboot bootloader
    

    Then do this, if you use Windows 10-11 you might need to install the Asus USB Drivers (if you get a waiting for fastboot devices prompt) If you are on Linux or MacOS, it should be easier, simply exectute the fastboot command as root (sudo fastboot...)

    fastboot oem asus-csc_lk
    
  • @PhaGWiZ , many thanks, this worked like a charm once I'd downloaded the ASUS USB drivers
