Google has just posted Android 5.0.1 factory images for the WiFi only models 2013 Nexus 7, Nexus 9 and Nexus 10 for those adventurous souls who are comfortable flashing the image to their devices. If you’ve got a 2012 Nexus 7 you’re out of luck for now, but I hear that Lollipop doesn’t run on that device so well so don’t be too bummed. Lollipop is still young, and will undoubtedly go through a bunch of small incremental updates before it begins to run smoothly across all Nexus devices.
