What is the best way to root a 2012 Nexus 7 running 5.1.1 Lollipop? I have had my N7 for about 5 or 6 months now, and I am considering rooting it. I would like to know the best one click rooting methods to use. I've heard of kingoroot, but I don't know if it roots 5.1.1 yet. Thank you
Use the Nexus Root Toolkit. It is the easiest method, and will walk you through all the steps (setting up drivers, etc.)
