Step 2. Enable USB-Debugging on your phone. USB-Debugging is required for the commands “adb” and “fastboot” to work. To enable USB-Debugging follow the steps from the screenshots bellow or click here.


Step 3. Enable OEM unlock on your phone. Activate the “Enable OEM unlock” on your phone from Settings > Developer options > check Enable OEM unlock . This is necessary for the bootloader unlock.

Step 4. Open Command Prompt or Terminal and enter the following ADB command, so the phone will reboot into the bootloader:

adb reboot bootloader

Note, if ADB is not detecting your device try switching your phone’s USB mode from Charging to MTP or PTP. Click here to read more about MTP and PTP.

Step 5. Once in the bootloader, use the following fastboot command to obtain Device ID:

fastboot oem device-id

Fastboot command will return a string. This is the Device ID which is needed to generate your unique unlock key. For example:

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

To generate your unlock key, you will need to paste together the 2 lines of output into one continuous string without “(bootloader)” or white spaces. In the example above, the Device ID would be:

CD58B679A38D6B613ED518F37A05E013F93190BD558261DBBC 5584E8EF8789B1

Step 6. Copy Device ID and IMEI into the LG developers unlock site and hit the confirm button. In a few moments the unlock.bin will be emailed to you. Download unlock.bin to computer. While the phone is still in fastboot enter the following command to unlock the bootloader, Nothe that: This will unlock your phone AND factory reset your device wiping all data!
