The leaked build of Android 4.2.2 for the Verizon Galaxy Nexus we first saw over the weekend has just hit the internet courtesy of a member at XDA that has pulled the build directly from a Google OTA server. The update is meant to bring Galaxy Nexus users on big red up from 4.1.1 to 4.2.2 -- build JDQ39 -- directly, with no fancy hoops. As we noted, this is an actual OTA file meant to be applied to stock and unrooted devices. This still doesn't mean the update is finalized or ready for release just yet, but it does give a whole bunch of legitimacy that the update is in its testing phases.
If you're interested in giving this update a go and have your Galaxy Nexus running on stock 4.1.1, you'll need to be rooted with a custom recovery -- or be able to temporarily boot a custom recovery -- to apply the update. If you're unsure on the process to accomplish either of those, head to the forums where we have some fantastic guides to walk you through it.
