How to Unlock Bootloader on MetroPCS LG Optimus L70 MS323

Quick and easy tutorial for unlocking the bootloader for MetroPCS LG Optimus L70 MS323.

Do this AT YOUR OWN RISK and I don’t guarantee it will work on all MetroPCS LG Optimus L70 (but successfully done on my phone).

Warning: Make backup before unlocking bootloader. This procedure will wipe the /data partition of your phone, so you will loose all your stored data, settings. SDCARD will BE WIPED!!!


NOTE: Must have busybox installed on your device, have USB debugging enabled, and the phone plugged in and set as charge only.

  1. Download the and extract it to your PC
  2. Install fastboot and adb. All of which is included in the
  3. Run script:

      • laf_script.bat

  4. Power off your device, plug in your usb to your computer, power on and hold volume up until in fastboot mode. If your phone boots to download mode then something didn’t work right, be sure you followed every instruction.
  5. Open Command prompt or terminal and cd to the same directory as your scripts, once there, type:
    • fastboot devices
  6. Be sure that your device is listed, it should be random numbers.
