    im trying to unlock the bootloeader of my lg g7, im follwing this steps here


    but now im stuck in the step 19 when i type fastboot oem unlock i can get 3 results

    FAILED (remote: 'unknown command')
    FAILED (remote: ' Set device unlocked! failed: 00000050')
    FAILED (remote: ' Device already : unlocked!') (it says its unlocked but in my screen it show that is locked)

    "fastboot devices" works, it shows my device

    (bootloader) Device unlocked: false
    (bootloader) Device critical unlocked: false
    (bootloader) Charger screen enabled: false
    OKAY [ 0.005s]
    Finished. Total time: 0.005s

    here, 3 attempts, you can see the results

    the waiting for device appeared because the device wasn't connected when i typed the command.

    your last ccommand entry seemed close to what it says in the guide:
    try using usb 2.0 and keep trying

    well, i disconnected my printer and speaker to use another usb 2.0 port, in the speaker port, im having this response

    FAILED (Write to device failed (no link))
    fastboot: error: Command failed

    anyway, still doesnt work.


    this message is shown even if you disconnect the phone, seems like a bug, it was needed to restart the pc for this message stop to show up

    Yes, im back,

    its been a few weeks trying to solve this but finally got a solution

    here is what i did

    execute the fastboot oem unlock with the unplugged phone

    the prompt will show <waiting for any device>

    restart your phone using the "Restart Bootloader", right after the screen turn black, plug the phone on usb 2.0
    and it will work, at least worked for me.
