It's been a long, long time coming, but the official Android 4.2 update for the Verizon Galaxy Nexus is here. The black sheep of the Nexus family has waited for four months to get updated to the latest release, and while Verizon is currently testing the software for a probable release later this week or month, you don't have to wait that long. Long-time Android tipster WinDroidGuy got his hot hands on the update ZIP package, and eager users can download it right now.
Google has just published the fully flashable image for the 4.0.4 update to the Verizon Galaxy Nexus (mysid). This allows users who either have been unable to receive the OTA due to using a custom ROM, or simply haven't updated, to flash their devices with a complete OS image, as opposed to using an incremental update file.
This will erase all of your data, so if you do flash it, be sure to back up your stuff.
