For those of you who want to root your Nexus 6, remember that in order to root a Nexus device, you will have to unlock the bootloader first. Unlocking your bootloader WILL ERASE EVERYTHING on your phone so we highly recommend you to root your Nexus 6 as soon as you receive it in the mail. Also, copy EVERYTHING (all your photos/videos) to your computer so you don’t lose them.
