The official update to Android 4.2.2 Jelly Bean has been leaked for the Verizon Galaxy Nexus earlier today. There were already some rumors regarding this imminent release and now it seems like they were tru and you can download and flash the Android 4.2..2 ROM using a custom Recovery or using the ADB sideloading method.
A link to the tutorial guide is posted at the end of this post and you should use it to learn how to easily flash the JDQ39 Android 4.2.2 firmware for your Galaxy Nexus. The Verizon variant of the Galaxy Nexus family is the last one to receive the update to the latest Jelly Bean build. Since this is a leak, then you should expect Verizon to launch the OTA Update of Android 4.2.2 Jelly Bean JDQ39 firmware some time this month. However, we expect it to be available already at the end of this week.
You can use the leaked JDQ39 zip file and install it on your Verizon Galaxy Nexus phone only if your phone is currently running the Official / Stock Android 4.1.1 JRO03O OS. This means that in case your phone is currently on a custom ROM or on an AOSP ROM then you will have to restore your device to stock Android 4.1.1 JRO03O ROM and, only after that you can flash the new Jelly Bean 4.2.2 build.
JDQ39 Firmware come with new radios and it should provide better signal and network quality. It would be great if you’d confirm this in the comments section.
This new update firmware will bring some stability improvements, tweaks to other areas of your phone’s UI. It isn’t a major update but you should still upgrade your device with it. If you don’t know how to use the Recovery mode or you cannot flash it via ADB Sideload commands, then you shouldn’t attempt to update the phone with JDQ39 JB 4.2.2 ROM. Instead you can wait until Verizon pushes the official OTA Update notification to stock Galaxy Nexus phones.
