I have a good news for LG Optimus L9 P760/P765/P768/P769 owners that after countless hours of searching on internet, finally I found the way to unlock bootloader on the device.
Instructions for unlocking Bootloader on LG Optimus L9
- Download the tool attached above and extract it to C:\
- Make sure you have USB debugging enabled. Phone should be in "Charge only" mode.
- Plug your LG Optimus L9 to the PC via USB cable.
- Go into the C:\UnlockL9 folder and run Flash_bootloader.bat your phone will then restart, now you have the bootloader unlocked
If you want to install CWM recovery:
- If your device unlocked, your will reboot in fastboot mode. Open again the same folder and run Flash_Recovery.bat this will flash the new CWM custom recovery and phone should restart again.
If you want to root the LG Optimus L9 Jelly Bean:
- Download the Supersu file and flash it in CWM, enjoy. http://www.lg-phones.org/how-to-root-lg-optimus-l9-android-4-1-jelly-bean.html
