What is Bootloader Unlock?

Before we dive into the process, let’s first understand what bootloader unlock means. A bootloader is a program that runs when you turn on your device and is responsible for loading the operating system. By default, the bootloader of your phone is locked by the manufacturer to prevent users from making unauthorized changes to the software. Bootloader unlock is the process of unlocking this security feature to gain access to the system files and install custom firmware on your device.


Before you start the process, there are a few things you need to prepare:

  • Make sure your LG Stylo 4 is fully charged.
  • Back up all your important data as the process will wipe your phone’s data.
  • Enable developer options on your device. You can do this by going to Settings > About phone > Software information and tapping on the build number seven times.
  • Enable USB debugging by going to Settings > Developer options > USB debugging.
