Root Nexus 6 on Android 5.0 Lollipop via Chainfire's One-Click Root

Chainfire, the developer of popular rooting tools for Android, has just rolled out his popular One-click rooting tool aka CF Auto Root (CFAR) on Google's flagship Nexus 6, which has surprisingly been the last among Nexus devices to receive this privilege.

Though the CF Auto Root was available much earlier than Google's official release of Android 5.0 Lollipop update, it took some time for Chainfire to fix inherent bugs with root apps before releasing the final build of his one-click rooting tool across all the Nexus devices.

It is imperative to unlock your device's bootloader before you proceed, although the rooting tool will attempt to unlock the bootloader prior to installing root access on your Nexus 6.

However, you must remember to enable OEM unlock via Settings > developer options before the bootloader can be unlocked.

Note: Rooting any device will void its hardware warranty, as you will be modifying system files to unlock OEM restrictions on the device. Nevertheless, you can easily unroot the device and restore it back to factory settings to regain your warranty status.

How Does CFAR Work or Enable Root Access on Nexus 6?

CFAR flashes a modified boot image (included in the package) to inject root and install SuperSU app into the system folder.

During the process of flashing the modified boot image, you might notice a red Android icon on your Nexus 4 screen that stays on for around 10 seconds before rebooting.

It must be noted that the device may reboot a couple of times before the root installation completes, and this is normal.
