Unlocking the LG Optimus L9 bootloader is possible in several ways. I will say right away that these methods may not work. I can’t even guess what this might depend on; for some, everything loads quickly, and for others, it doesn’t load at all.

There is one “but” in the bootloader - without Jelly Bean firmware, and on ICS it is impossible to unlock it. Let's look at options for unlocking the L9 bootloader. First of all, the preparatory step should be to make backups of all necessary data and applications, since during unlocking the bootloader all user data will be deleted.

Then you need to install the official Jelly Bean 4.1.2 firmware. If you already have it installed, then you don’t need to do this. After installing the firmware, we update the phone using any of the following methods: OTA, LG Mobile Support Tool or KDZ.

The next step is to install the driver for LG. To do this, download the driver and connect the phone to the computer.

Download LGUnitedMobileDriver

After installing JB, the phone with the SIM card must be turned on for at least 30 minutes. It is important that the phone does not reboot before the unlocking process begins. Otherwise, nothing may work out. Plus, you may be left with your phone locked forever.

If all of the above has been completed, then you can proceed to the unlocking itself. It should be noted right away that an unlocked bootloader cannot be reverse-locked, which means that after this procedure you can no longer count on the phone’s warranty.

Method I: Unlocking the bootloader using the Rom toolkit utility.

Download Rom Toolkit

This utility allows you to additionally install recovery.

First of all, you need to install and open the Rom toolkit. After this, you need to perform USB debugging by selecting the developer options settings. In this case, you need to connect the phone to the computer in the “LG Software” mode. By selecting “Unlock bootloader”, a black screen should appear with a warning about loss of warranty. If you also need to install recovery, then you need to press “Volume Up”, which will confirm your consent and unlock the bootloader. To refuse, you need to press the On button. Entering recovery is done by simultaneously pressing the volume up button, the Home button and the power button, which must be held until it vibrates. After this, you need to click “Flash recovery”, which will automatically reboot the phone. IMPORTANT: while performing all of the above steps, do not turn off or disconnect the phone.

Method II. Unlocking the bootloader using the LG Optimus L9 ToolKit utility.

Download LG Optimus L9 ToolKit

The peculiarity of this utility is that it works exclusively on P760 firmware, therefore, if you have P765 or P768 firmware installed, then first you will need to install P760 firmware. You can return to the previous firmware after unlocking the bootloader.

You need to start unlocking with USB debugging (select Settings, then Developer Options), connect the phone in charging mode to the computer. After this, we install LG Optimus L9 ToolKit, open it, find Unlock The Bootloader, and select Unlock BootLoader. A black warranty warning screen appears. In order to agree and unlock the bootloader, you need to press the volume up button (the on button to refuse). When installing recovery, it is important that the phone does not turn off or become disconnected. In the program, we find the Flash Recovery tab, and select from the list the recovery that is needed.

The result of a successful installation will be an automatic reboot of the phone.

3. Method III. Owners of P765 and P768 need to install the firmware from P760 to unlock their phone.

This will also allow you to install a custom recovery.

First of all, to unlock the bootloader, you need to download the UnlockL9.rar archive and unpack it to the root of the C:\ drive on your computer.

Download UnlockL9

After this, you need to perform USB debugging (select Settings, then Developer Options). Connecting mobile device in the “LG PC Suite” mode or in the charging mode to the computer, run Flash_bootloader.bat (for this you need to have administrator rights). After the window with information about the loss of warranty appears, enter confirmation of the unlocking (by pressing the Volume Up key, to refuse - the On key).

After unlocking, the Fastboot message should appear on the phone screen. For installation custom recovery, you need to run Flash_recovery.bat as an administrator. Upon successful unlocking, the phone will automatically reboot.
