Motorola and Verizon released an offical DROID RAZR and RAZR MAXX update for Android Jelly Bean 4.1.2 last Thursday. Although the update added several new features like Google Now and Smart Keyboard, it's hardly the cutting edge, since we all know a Jelly Bean 4.2.2 is already out there.
Now you can get the update by way of an AOKP Build 4 Custom ROM for the Droid RAZR. If you've been thirsting for the latest Nexus-line features, this step-by-step guide will deliver you to the promised land.
Preparations
One does not simply update an Android.
First, go to the official Motorola website to download official Android drivers. Then, connect your device and create a backup. Remember to enable USB Debugging on your device and as always, make sure it's unlocked.
Make sure your battery is charged to at least 80 percent before proceeding.
Step 1: You'll need the AOKP Build 4 Android 4.2.2 Jelly Bean Custom ROM for the Motorla RAZR XT912. Download links for the package tend to go dead quickly, so do a little Googling to find it.
Step 2: Connect your RAZR to the computer and transfer the ROM file to the SD card.
Step 3: Go to the Google Play store and download the ROM Manager.
Step 4: Open ROM Manager and select "Reboot into Recovery."
Step 5: Enter the CWM recovery mode. Delete all data from the device, then select "flash zip from SD card" by pressing the Power key.
Step 6: Press "choose zip from SD card" again. Then select the "Android 4.2.2 ROM" using the Volume keys to navigate. Press the Power key to install it.
Step 7: Hit "Go back" and then reboot your RAZR through the recovery menu.
Step 8: The device will restart, which will take about 5-10 minutes. Do nothing until this process completes.
Your phone is now rooted. Kudos.
