Although Motorola has recently released the Android 4.4 update on the Moto X, it may take a while before the manufacturer manages to launch the update on other devices in its line-up. In fact, the highest priority right now is probably given to Verizon's new Droid Ultra line-up. There's also the Droid RAZR HD to consider, so in other words, it could take a long time before RAZR owners will be abne to enjoy the KitKat release. There's also a possibility that the older RAZR line-up will never receive the official update.

But, fret not, because there are ways to experience KitKat on the RAZR (XT910) with the use of custom ROMs. This is a guide that will allow you to flash the recently released CM 11 custom ROM on the Motorola RAZR. As most of you know, CM 11 is based on Android 4.4, but the firmware also includes several extra features, such as, battery and performance optimizations, an upgraded web browsing experience and more.

NOTE: Please keep in mind that this particular CM 11 ROM for the RAZR is not an official CyanogenMod release. In fact, it's a "port" developed by XDA members and developers. As such, you may run into certain bugs with this build.

  1. Download the necessary CM 11 ROM for the Motorola RAZR XT910 by visiting this link
  2. Since the ROM does not include Google apps, you'll need to download a separate Gapps package from this link
  3. Save both files on your computer. Don't unzip them
  4. Connect your Droid RAZR to your computer using the USB cable. (Keep in mind that "USB debugging" should be enabled at this point)
  5. Copy and paste the downloaded files onto your phone's SD storage
  6. Once the files have been copied, unplug your smartphone from your PC
  7. Boot your smartphone in recovery mode (refer to the guide above)
  8. You will now create a NANDROID backup of your current ROM. Assuming that you don't like CM 11, or if you experience issues with the ROM, this backup will allow you to return to your current ROM. To create a backup, select "backup and restore", name to the file and then save it

    • NOTE: If your smartphone takes more than 10 minutes to reboot after the flashing, or if the device is stuck in a boot loop, then you will need to repeat the guide from the beginning. Don't skip any steps.
  14. Congratulations! You can now add your Google account and perform restores from the backup apps

NOTE: If you wish to return to the previous ROM, you can use the NANDROID backup in order to do so. Reboot your handset in recovery mode (as instructed above) and then select "backup / restore". Follow any additional instructions as they pop-up on the screen.
