Last weekend, a lucky user finally saw the much awaited Android 4.2.2 update arrive on his Verizon Galaxy Nexus, but it seems Verizon is not yet ready to push out the update to everyone. However, the aforementioned user grabbed the OTA update’s link from the official Google servers and it is now available for downloading and installing manually.
With Android 4.2.2, users will see quite a few new features, including a new keyboard with gesture typing, Daydream screen saver mode for displaying images and other content when phone is idle, faster performance and smoother app switching, 360 degrees panorama mode and a new camera interface, and many other small but useful changes. The update also includes new radios for the device, which are reported to improve the network strength.
We have prepared a guide to help you update to Android 4.2.2 manually if you don’t want to wait around for dear old Verizon to make it available. There are two versions available – one is the official OTA update that you can install on a stock unaltered Android 4.1.1 ROM, and the other is a custom version that is pre-rooted and has to be installed from a custom recovery.
All right then, once you’ve decided whether you want the official Android 4.2.2 update or the custom rooted version, follow the respective instructions below to install it on your Verizon Galaxy Nexus.
Compatibility
The procedure described below is only for the Verizon Galaxy Nexus. Do not try it on any other device.

This is the official OTA update that you can install if your phone is on 100% stock Android 4.1.1 ROM (build number JRO03C, which you can confirm from the Settings » About phone menu). It will also install the new radios along with the update, and should be used by anyone simply wishing to update from Android 4.1.1.

You will need to unlock the bootloader on your device to install it, which will wipe all data from your device (unless you’re already on an unlocked bootloader). This doesn’t include the new radios from the update, but those can be manually installed later if needed.
The procedure to flash this ROM involves unlocking the bootloader on the device, which causes all the data on the device to get wiped, including everything on your internal storage. So, backup installed apps and other data such as contacts, messages, bookmarks, etc, by referring to our Android Backup Guide for help. Then, copy everything from the SD card to your computer, which will also include the apps and data you backed up.Your phone’s bootloader will need to be unlocked to flash the ROM and you also need ClockworkMod (CWM) recovery installed on it.

Then, reboot the phone after wipe is complete.Installing New Radio
