One of the reasons rooting the Google Nexus 6P by using the SuperSU application via a custom recovery is so advantageous is because it allows you to think about installing custom ROMs right away without having to do any additional work. There are many custom ROMs worth checking out for what is one of the most popular smartphones in the world today — the Google Nexus 6P.

REQUIREMENTS

• The following guide is made for the Google Nexus 6P. Ensure that you have the 6P variant in your hands, or else you risk bricking the device.

BEFORE WE BEGIN

• You will need to backup the data and turn on the USB Debugging Mode on your 6P’s settings before you can use this guide. Those of you who are unable to find the Developer Options menu to check the box for the USB Debugging Menu might need to unlock it from the About Device menu first.
• Note that rooting your Google Nexus 6P smartphone will void the warranty on your device. You can get the warranty working again by unrooting and removing any of the customization options from your device.

11. Once you have installed the SuperSU, choose the option to reboot the system fro the recovery menu.
