The Motorola Droid RAZR and RAZR MAXX can now be updated to the official Android 4.1 Jelly Bean using the instructions that I have listed in this article. Make sure to read the entire post and note that you can even use this post for Droid RAZR and RAZR MAXX phones that are rooted and preserve their current state. If you cannot complete the update, then you should ask for more help in our comments field and we will try to come up with solutions for any problems that you encountered in the process.
Android 4.1.2 Jelly Bean has been sent OTA for the Motorola devices but not all users got this update because they are rooted. Installing this update will roll your device back to stock Android 4.1.2 JB and Motorola UI. However, the new update doesn't feature the former Motorola bloatware and you will see that the Google Chrome is now the default browser, while the Social Location, Alarm and Timer have been removed completely. The new OS looks much more like the stock Android OS.
Read the guidelines below to learn what steps you need to take in order to make sure that you flash the firmware update at your first attempt. Here's what you need to know:
- Use this tutorial only for the Motorola Droid RAZR and Motorola Droid RAZR MAXX phones with the model number XT912. The files you find in this post will not work with any other smartphone or tablet device.
- Also, the OS currently installed on your Droid RAZR / RAZR MAXX should be running the 100% stock Android 4.0.4 ROM with build number 6.16.211 and for the Android 4.1 Jelly Bean build number 98.72.8 that was leaked in December 2012. Check the 'build number' in by going through Settings > About Phone options.
- Note that this guide will work for rooted phones also but not for those devices running custom ROMs. The tutorial will temporarily unroot your device and then you will be able to flash the new update. After the update is installed you can easily restore the root status.
- Create backups of all the files that are currently stored on your smartphone. The tutorial shouldn't wipe any data from your device but you should be prepared in case something goes wrong.
- IMPORTANT: you need to have a microSD card installed on your device as you cannot use the internal SD card storage to install the new update.
- Enable USB debugging option from the Android Developer Options.
- Make sure that your phone's battery has at least 50% power left in it. This will prevent it from powering off during the installation process of the new update files.
- This is a guide for advanced Android users and you shouldn't attempt to use this tutorial in case you're a novice. Read all the instructions listed and ask for extra help in comments.
- We cannot be held responsible in case you lose data or you brick the device.
