If you're still rocking a 2013-era Nexus 7 with LTE, or a 2012 mobile version, we've got some great news today. Google has just dropped the Lollipop factory images for the both devices, and they're version 5.0.2 to boot.
This particular build is labeled as LRX22G, the the very same build deployed a couple of weeks ago for the Nexus 10 and Nexus 7 Wi-Fi versions. This marks the official jump from Android 4.4.4 KitKat to Lollipop for both devices.
You can grab the images from the links below if you decide you can't wait for the OTA to arrive. If you need a little assistance with doing so, also be sure to check out our guide on the subject here.
