This latest root method works on all current Android versions of multiple Motorola phones
Yesterday we witnessed a Motorola milestone (no pun intended) when Dan Rosenberg announced he had found a method to unlock the bootloaders of multiple non-OMAP Motorola phones, including the Attrix HD, Droid RAZR HD/HD Maxx, and the Droid RAZR M. The unlock method would require root access, which unfortunately left Droid RAZR HD users out in the cold if they had already accepted the latest OTA update to Android 4.1.2.
Coming to the rescue of those disenfranchised Droid RAZR HD owners, Dan has released a new exploit that roots the following Motorola phones, regardless of what Android version they're currently running:
Droid Razr HD
Droid Razr Maxx HD
Droid Razr M
The above phones are the only ones that are officially supported with this new root method. However, Dan has stated that this exploit will likely work with other phones -- including non-Motorola devices.
