Android 4.3 was officially unveiled and released today to the Android Open Source Project. In a surprisingly timely fashion, Google also released both the factory images and OTAs to the Nexus 4, 7, 10, and the Galaxy Nexus.
In this post, I will show you how to easily update your Nexus 4 to Android 4.3 JWR66V without losing data or needing root, whether because you are having trouble flashing the OTA, because one is simply not available to you yet (these notoriously take weeks to propagate to everyone), or because you're running something else and want to return to stock.
