How to root Motorola RAZRi XT890 running Android 4.0.4

This procedure is only valid for Motorola RAZRi model XT890 (Intel inside) running Android 4.0.4 (system version 81.5.39001.XT890.Retail.en.GB). The following instructions refer to rooting the RAZRi from a Windows 7 PC.

You need to download the Android SDK 

Go to the Android Developer web site and download the Android SDK for Windows.
Make sure you then set the PATH environment variable to the <sdk>\platform-tools directory where all the tools can be found from the command line.

Install the latest Motorola USB drivers for you phone

Install the latest Motorola USB Drivers. Get them here.

Your phone should be factory unlocked

This is a must or else rooting the device will fail with the phone stuck on the bootloader. Go to the Motorola Web site and follow the step by step instructions. Basically open a Command Prompt window and get your Device ID by running the fastboot command. The instructions from Motorola are the following:


  1. Put your device in fastboot mode (press the power button and volume down button at the same time and connect your device to your computer with a USB cable).
  2. On your computer, open a command prompt or Terminal session.
  3. Go to the Directory where you installed the Android SDK tools, and type:$ fastboot oem get_unlock_data
  4. This fastboot command will return a character string. This is the Device ID which you will be using to generate your unique unlock key.

    Example Device ID (PC User)$ fastboot oem get_unlock_data
    (bootloader) 0A40040192024205#4C4D3556313230
    (bootloader) 30373731363031303332323239#BD00
    (bootloader) 8A672BA4746C2CE02328A2AC0C39F95
    (bootloader) 1A3E5#1F53280002000000000000000
    (bootloader) 0000000

At this point if you submit the device ID to the web form, Motorola will send you the unlock code via e-mail (after warning you that the warranty will be void if you do so).
To unlock the device:


  1. Turn off your device.
  2. Start your device in fastboot mode. To do this on most Motorola devices, push and hold the power and volume down at the same time, release the power button then release volume down. The device will power up in fastboot mode
  3. Connect the device to the computer with a USB cable. You'll get a confirmation message on the device will indicate that it's connected.
  4. Open a command window or terminal on your computer.
  5. Change field to show the path to the tools folder within the Android SDK folder.
  6. Verify that the desktop and device are connected by entering the following in the command field:$ fastboot devicesYou should see that your device is connected.
  7. Now you will unlock the bootloader. Simply enter the following in the command line:$ fastboot oem unlock UNIQUE_KEYThe UNIQUE_KEY is the code you received in the email. It is case-sensitive.
  8. If the line was entered correctly, your device's screen will confirm that your device is unlocked. You have just unlocked your device's bootloader.


Root the device

Get the RAZRi rooting utility for Windows. Get it here.
Extract the zipped files and from a Command Prompt or terminal window, change directory to the location of the utility. Make sure your RAZRi is connected to your Windows PC via the USB cable. Finally run the Root.bat command, follow the instructions, and cross your fingers.
After rebooting at least three times the phone should be rooted.

    1. I don't think so. These instructions will only allow you to become root on your phone so that you will be able for example to install programs in the /system directory (for example by running "adb shell" and then "su -"). Try to search the web for how to recover you razri.
