Ok y'all I'm just going to come out and preface this by saying that I'm a noob when it comes to rooting phones and don't quite understand it. What is rooting exactly? What are the benefits to rooting? Does it void the phone's warranty? And what is the best method for rooting the Droid RAZR M running 4.1.1 Jelly Bean? Is there any way to un-root a phone?
