There is finally a root for the Jelly Bean 4.1 OTA for Motorola Droid RAZR and MAXX.

Per reports, the previously touted ‘unrootable’ Jelly Bean 4.1 OTA for Motorola Droid RAZR and MAXX has finally received a highly requested and massively anticipated root, thanks to Dan Rosenberg.

Rosenberg is noted for rooting a number of devices in the past. “Some readers are likely familiar with Mr. Rosenberg's work, as he's rooted everything in sight from the Droid RAZR/MAXX HD to the RAZR M, all the way back to the LG Spectrum. As a security researcher, he's even given (and published) a helpful presentation on rooting and modding for the security conscious,” the Android Police states.

Recently, Rosenberg found a successful root method for the phone's 4.1 Jelly Bean OTA, which began rolling out last Christmas Eve. At that time, users reported that the original Droid RAZR (and also RAZR MAXX) was getting an update roll out that would upgrade the device to Jelly Bean (Android 4.1.2).

This update was 331.7MB in size and needed a WiFi connection before the start of the download. Later, after updating to the latest Jelly Bean, a few users complained that they were unable to root the devices as soon as the Jelly Bean was introduced in the phone. However, now with Rosenberg’s root, it seems like this highly anticipated root is possible.

“So our fearless root master, Dan Rosenberg (djrbliss), has successfully achieved root for the JB OTA and it's here first on DR.com! This root exploit is applicable to the RAZR and RAZR MAXX (XT912). This means all of you who lost root through the OTA update will now be able to root your devices once again,” the official thread states.

“A huge thanks to Mr. Rosenberg for all his hard work and dedication! He is the first one to achieve root so, as promised, the bounty is his.”

In order to run this new exploit (only available for Windows, at the moment), users will need to download and extract the entire zip file, while ensuring the device is connected via USB. Users will need to make sure that they have the latest Motorola USB drivers installed, with the USB debugging mode enabled.

Once that is done, users will just need to double-click "run.bat" to perform the process.
