How To Unlock Bootloader On LG G6 H870 European Variant

After the lackluster performance of the LG G5 last year, LG launched its highly anticipated flagship, the LG G6, at the Mobile World Congress (MWC) in Barcelona in February this year. Following the commercial failure of the LG G5, which faced consumer resistance due to various controversies and boot loop issues causing the device to shut down on its own, LG incurred financial losses and even faced a lawsuit. Eager to put the past behind them, LG introduced the impressive bezel-less design of the LG G6, effectively capturing the attention of consumers.

If you own the LG G6 H870 European variant, you now have the opportunity to unlock the bootloader using a straightforward method. However, it’s important to note that officially unlocking the bootloader on the LG G6 H870 will void the device’s warranty. Therefore, if you are considering unlocking the bootloader, it’s advisable to wait until your warranty period has expired. In the event that you have already unlocked the bootloader on the European LG G6 variant, know that you can always re-lock the bootloader on your device at any time.

This guide is specifically for the LG G6 Variant (H870). Please do not attempt to use this guide on any other model, as it may not work and could potentially damage your device. Below, you’ll find a comprehensive, step-by-step guide on how to unlock the bootloader on your LG G6. While the process can seem a bit complex, we’ve simplified it as much as possible to make it easy to follow.

What is a Bootloader?

A bootloader is a program that runs when you power on your device. It initializes the hardware, loads the kernel and ramdisk, and starts the boot process. This concept is not unique to smartphones but applies to all technology, including laptops and PCs. Most Android device manufacturers lock the bootloader to prevent unauthorized modifications, even though Android itself is an open-source platform. Unlocking the bootloader allows you to install custom ROMs, root your device, flash TWRP recovery, and make other modifications that are otherwise impossible. However, unlocking the bootloader will void your device’s warranty, as manufacturers want you to stick with the stock ROM.

Prerequisites

  • Battery Charge: Ensure your phone is charged to at least 70%–80% to avoid any interruptions during the process.
  • Warranty Disclaimer: Unlocking the bootloader will void your warranty.
  • Data Backup: Unlocking the bootloader will wipe all data on your device, so make sure to back up everything important before proceeding.
  • Follow Instructions Carefully: Follow each step carefully. Skipping steps or incorrect execution may damage your phone, and we are not responsible for any such damage.
