Motorola Droid Razr users have been having a frustrating time trying to root their devices since the official 4.1 JellyBean OTA update, which began rolling out at the end of last year. For some reason root access was lost when upgrading to the new version of Android, and previous methods of rooting the handset became obsolete. The situation irritated some users so much that a $450 bounty was raised, to be awarded to the first person who could crack the problem.
Well, Dan Rosenberg recently announced that he has successfully achieved root access on Razr and Razr Maxx devices, and so he claims the bounty. Just to go one step further, Dan has also made the root exploit simpler than ever to install — it can be done with just the double click of a BAT file.
Installing the exploit is very simple, but before starting make sure that your device is recognized by your computer and that you have the latest Motorola USB drivers installed. Then all you need to do is download and extract the required zip file to your desktop, enable USB debugging mode on your handset, connect your phone via USB, and then double-click “run.bat”.
If you're in need of root access on your Razr handset then you'll need to head over to the original thread and register before the download links become visible.
