Devices from Google are not only great at official software support but also have just as great unofficial support. It’s a fact almost every Android enthusiast probably knows. While official software support is great, many of us still feel the need to mod it. Mostly because stock Android is just a little too bland. Luckily, the Google Pixel 2 and Pixel 2 XL, being so modder-friendly can easily be rooted. Before you can root them, or install a custom recovery or ROM, you’ll need to unlock the bootloader. Fortunately, it is just as easy to unlock bootloader on the Pixel 2 and Pixel 2 XL.

In case you’re not aware, the bootloader is a piece of software that loads up the OS and acts as an OS. It’s a thin interactive layer between the hardware and the OS, much like the BIOS on a Windows PC. The bootloader is locked by default to only load up official software from the hardware manufacturer. Which is why it becomes necessary to unlock the bootloader in order to install a custom recovery and thus a custom ROM. In this case, it is necessary to even root.



Unlocking the bootloader and rooting your phone will void your warranty. Worst case scenario, you may even end up with a non-usable device. DroidViews cannot be held responsible for your actions. Proceed at your own risk.
