The full factory images for Android Lollipop 5.0 were released today, and the first image up is the one for Nexus 9/ Volantis. Even if most of you are probably not helped by it, at least you know things are moving along.
UPDATE: Nexus 5, Nexus 7, Nexus 4, Nexus 10 , Nexus Q, Nexus S, Nexus maguro, Nexus toro and Nexus toroplus images included.
The factory images are important because they let Nexus device users undo anything they may change or mess up on their device. They are also good for getting back to the stock Android before an OTA update. In case you’re an avid modder, you can now be assured you will have a certain way to go back to stock Android just in time for that OTA next time!
