    If you are looking to unlock bootloader on LG phone then here is a very simple Step-by-Step guide on the same.

    I will be taking you through a simple easy Step By Step beginner’s guide which I bet to be a buttery smooth experience even for the first time users. Just make sure to follow each instruction and you must not SKIP any step unless stated in this guide.

    It is important to understand that there could be some serious impacts if the instructions are not followed properly.
    Keep this in mind that you will lose your data while unlocking the bootloader on LG Phone and hence before proceeding further you may consider backup all the data on your LG Phone.
    YOU are the only person making changes to your phone and I cannot be held responsible for the mistakes done by you.


    How to Unlock bootloader on LG Phone


    1. LG USB drivers
    2. LG Unlock Bootloader page
    3. A PC Installed with ADB and Fastboot.
      15 Seconds ADB Installer for Windows
      Minimal ADB and Fastboot for Windows


    Setting up the PC before you Unlock Bootloader on LG:

    1. Download the USB driver installer from above download links and Install it on your Windows PC.

    3. Install 15 Seconds ADB Installer or Minimal ADB and Fastboot for Windows.

    Create an LG account and get ready for LG Bootloader Unlock process:

    1. Register on LG website to start the Unlock Bootloader on LG phone or device.
      Confirm e-mail, login and setup your LG account.
    2. Then go to the LG bootloader link and click on Starting Unlocking the Bootloader link at the bottom of the page.
    3. If the LG Bootloader Unlock Legal Terms will be displayed on your screen, then click I Accept to proceed.
    4. Your name and email address will be displayed.
      Below that you select your device Model number
    5. In the next box enter the first 15 digits of your phone’s IMEI number.
      You can view the IMEI number by entering *#06# on your phone or selecting the Settings > About phone > Status > IMEI menu
    6. In the next box it asks for the Device ID for which you need to follow the below steps:
      – Enable Developer Options
      – Enable USB Debugging (in Developer Option Menu)
      – Enable OEM Unlock (in Developer Option Menu)
    7. First Enable Developer Options.
      Go to Settings > About phone > Software info and tap Build number 7 times. Return to the previous screen, select Developer options
    8. Then Enable USB Debugging and OEM Unlock from Developer Options settings menu.
    9. Next, you open the command window on your Windows PC.

      To open a command window in the current directory in Windows, press shift + Right Click anywhere on Windows explorer, or some folder. Then on the menu opened, just press the “w” key on the keyboard or select “Open command window here” to open a command window.

    10. Now connect your Android to the PC using a USB cable.
    11. Enter the following command on the command window opened:
      adb reboot bootloader

      to start your LG phone in bootloader mode where you can get the LG Device ID.
      If your device asks permission such as “Allow USB debugging” then just tap on OK to proceed.

    12. Now when your Android is on the bootloader mode just execute the following command on the console:
      $ fastboot oem device-id
    13. The above fastboot command will return a character string.
      This is the Device ID which is needed to generate your unique Bootloader unlock key for your LG phone.

      The dvice Id string from fastboot will look something like below:

      Example Device ID (PC User)$ fastboot oem device-id
      (bootloader) Device-ID
      (bootloader) CD58B679A38D6B613ED518F37A05E013
      (bootloader) F93190BD558261DBBC5584E8EF8789B1

    14. Now you have to copy only the Alpha-Numeric data by discarding the (bootloader) on Windows output

      So the Device ID will look something like the below:

    15. Copy that device Id in the LG Unlock Bootloader page and then click on confirm.

    If you have entered valid IMEI number and Device ID, then a Bootloader unlock code for your LG phone will be sent to you on your registered e-mail Id.

    Follow the next set of instructions to unlock bootloader on LG phone if you have got the unlock key on your e-mail.

    Finally, the actual LG Unlock Bootloader process:

    1. By now you will still be on the bootloader mode. If not, then reboot your LG phone into bootloader mode by connecting the phone to the PC and executing adb reboot bootloader on the Windows command window.

    3. Enter the following command in the bootloader mode to unlock the bootloader on LG phone:
      $ fastboot flash unlock UNLOCK_KEY

      UNLOCK_KEY is the LG bootloader unlock key that you have got in the e-mail.

      THAT’s ALL.

    By now you should already have an unlocked bootloader onyour LG phone.
    But to verify that the bootloader on your LG phone is really unlocked or not, you can follow the below instructions.


    How to verify if you have Unlocked Bootloader:

    1. By now you will still be on the bootloader mode. If not, then reboot your LG phone into bootloader mode by connecting the phone to the PC and executing adb reboot bootloader on the Windows command window.
    2. Run the following command on command window:
      fastboot getvar unlocked

      The above command will return “unlocked: yes” is the bootloader is unlocked and “unlocked: no” if it is not unlocked.
