Getting back to stock .211 can be accomplished by using the Droid RAZR Utility by Matt L Groff, found here (Droid Razr Utility 1.82 [Windows] For Verizon Droid Razr And Droid Razr Maxx Only - DroidRzr.com). The first link for the download is by registration only, but the second link is completely free and will start immediately. Once you download the utility, you'll also need to make sure you have the proper drivers installed on your computer. Then run the utility and follow directions in that thread to flash back to .211. If you are rooted or wish to root and retain root once you update, you'll need to also install the Voodoo OTA Rootkeeper from the menu and then run it, protect root, then temp-unroot before installing Jelly Bean. Then you can install the new Jelly Bean update (if you wish). Once Jelly Bean is fully installed and working properly, you will run the Rootkeeper again and restore root.
Remember, proceed at your own risk.
