Motorola is really pushing hard for the updates of its devices that run on Android OS. Since the start of 2013, Motorola has been rolling out updates for Droid RAZR and RAZR Maxx, but still a lot more needs to be done to finish updates for all devices that belong to the RAZR family.

For those who are waiting for the update of Jellybean 4.1.2 on RAZR M, there is a good try from the developers of Cyanogen Mod. The developers released a Jellybean 4.1.2 custom ROM firmware under Cyanogen Mod 10 for the Motorola RAZR M for users who cannot wait to feel and enjoy the Jellybean features.

As usual, this is a custom ROM which means, the device must be ROOTED to be able to do this. To check if your device is rooted, download an app called Root Checker from the Play Store to determine your RAZR M root status.
