How to root Google Pixel Smartphone, Flash TWRP

    As a strategic move, Google decided to ditch their Nexus series and came up with an all-new lineup of Pixel devices. The current gen flagship of this pixel range comprises of Pixel and Pixel XL. Both the smartphones are manufactured abiding by the stringent guidelines set by Google. These devices receive the latest security patches related to Google every month, bug fixes and software updates directly from Google, making sure you always have the latest and the greatest.

    Being a Google device, it surely attracts a lot of attention from the developer community, meaning you’ll have access to a ton of custom ROM, custom kernels, and mods/tweaks.

However it should be noted that unlocking the bootloader, which is a primary and mandatory step involved in the rooting process could open up the device to a lot of vulnerabilities and rooting a device could make the device stop receiving OTA updates pushed by the manufacturer.

    Unlike most devices which require flashing of images, Pixel devices need to be rooted by writing the boot image using a fast-boot command.

    • This should reboot the device to TWRP, now go to install and select the zip to start the installation process. Swipe right to confirm installation.
    • Choose the SuperSU zip to install root.
    • On successful installation it is recommended to go to the wipe page and wipe cache and art cache for smooth operation and to avoid any bugs.
