For customers who want to participate in Android development using LG smartphones, we offer a method to unlock the bootloader on some of our devices. After this unlock, the device will also execute code that was not verified by LG, a mode which creates some risks but is useful to develop custom operating software.

Please be advised that this feature is intended for developers only.

Therefore, we strongly recommend not to unlock the bootloader unless you fully understand what you are doing.

For normal operation of the device it is NOT necessary to unlock the bootloader!

LG devices have a fully optimized, certified and tested version of Android, and unlocking the bootloader will change the software. Therefore, it is important that you take time to read and that you keep the following in mind before unlocking the bootloader to customize your device.

1. Once your phone is unlocked, it will no longer be covered by LG warranty.

As we cannot guarantee the proper operation of our hardware with custom software, we are not able to maintain the full scope of warranty for your device after you have unlocked the bootloader.

Because of that we have a responsibility to let you know that defects which may result from, or were caused by custom device-software may not be covered by LG warranty.



LG can no longer guarantee the full functionality of your device after you unlock the bootloader. Unlocking your device may cause unexpected side effects that may include but are not limited to the following:

- Your device may stop working.

- Certain features and functionalities may be disabled.

- Your device may become unsafe to the point of causing you harm.

- Your device becomes physically damaged due to overheating.

- The behavior of your device may be altered.

- Some content on your device may no longer be accessible or playable due to invalid DRM keys.

- All your user data, settings, and accounts may disappear. (Therefore, we recommend that you backup all your data).

- Software updates delivered via LG FOTA (Firmware Over the Air) or Web Download services may not work on your device anymore.



LG will not be responsible for the damages caused by any custom software being flashed to your phone.

2. Some features and services might not be supported anymore after the bootloader is unlocked.



When unlocking the bootloader, applications which require a trusted execution environment (TEE) to operate will not work properly because after unlocking the bootloader the device will no longer be trusted.

Unlocking the bootloader will also affect the DRM protection of your device, therefore some applications which require DRM protection may not work anymore or block certain functions due to this untrusted state.

Common examples for affected applications are services which offer download/streaming of paid multimedia content like music and movies or services offering mobile payment.

3. Unlocking the bootloader may make your device become vulnerable.

Using custom ROM may lead to monetary damages due to viruses, malwares, and leakage of personal information from hacking. You will be responsible for all such damages that occur after unlocking the bootloader.



Unlocking the bootloader could cause unexpected side effects. Therefore, we strongly recommend that you do not unlock the bootloader without understanding of all the risks involved.

If you still want to unlock the bootloader and understand the potential result of doing it, then we confirm that your device can be unlocked and you should proceed with the following unlocking Instructions:

- For step by step unlocking instructions, see the ‘How to Unlock the Bootloader’.

- For a complete list of supported devices, see the ‘Supported Devices’.
