2. Reboot your device into ClockworkMod Recovery. To do this, turn on the device when you see the red Moto logo, wait for two seconds and then press and hold down only the Volume Down key until you see ‘Android Recovery’ on the screen. Then press the Volume Up button to enter recovery.
3. You should make a nandroid backup at this point via CWM if you want to go back to your previous ROM.
4. Use the Volume Up and Down keys to navigate and select Wipe cache partition by using the Power button. Confirm on the next screen by selecting Yes – Wipe cache.
5. Go back to the previous menu and select Advanced > Wipe Dalvik cache. Confirm on the next screen by selecting Yes – Wipe Dalvik cache.

Once your device restarts, it should be running the latest and the greatest from Google plus you’ll still have your root!!
