What is Bootloader?

The bootloader is something that starts up whenever you start your device. The bootloader is responsible for sending the instructions to the operating system for booting up the device. The Android device packs all the system files in one place and all the other application files in the other storage space. And, this is the reason why the bootloader is locked on any smartphone. If you by accident or deliberately messed up the bootloader file then, you might permanently damage your device. Moreover, unlocking the bootloader will void your warranty and also wipe out your internal memory. So, if you are considering unlocking the bootloader of your device then, always make sure to make a backup of your device memory.


Once you are equipped with all the information regarding the bootloader, you need to have the below-mentioned files and tools ready before heading to unlocking the bootloader;

  • Make Sure your device is charged at least 70%.
  • We would recommend you to use the original USB cable that came in the box with the device.
  • Download ADB and Fastboot tools.
  • Make sure you have proper USB drivers installed for the Google Pixel 3a and 3a XL.
