Motorola’s new lineup today got root and thanks to Dan Rosenberg, aka @djrbliss at XDA for this root on various new Motorola device. The devices which attained root are Motorola DROID RAZR HD, RAZR M, Atrix HD, Photon Q, and RAZR i. We’ve heard that not only does this root method work with the shipping Ice Cream Sandwich that is on the phones, but also the Jelly Bean leak for the DROID RAZR M, which means it should work on the final Jelly Bean over-the-air update for these phones.
It involves hooking up your device to a Windows PC, downloading a zip (found below), extracting that zip, installing current Motorola drivers, and then running a run.bat file which gives you simple instructions.
Head over to XDA for More and instructions.
