It’s been a long wait, but at long last Lollipop is ready for the Nexus 7 (2012 and 2013) models with mobile data.
When Lollipop was initially released, just the WiFi-only tablets received the update and so owners of the 3G and LTE models were understandably pretty annoyed. With no word from Google no one really knew when to expect the update. Until now.
The 5.0.2 factory images for both the Nexus 7 2012 3G model (Nakasig/Tilapia) and the Nexus 7 2013 LTE (Razorg/Deb) are now live along with the updated driver binaries to match. These images carry the build number LRX22G which is the same build as the recent updates for both WiFi-only Nexus 7 models as well as the Nexus 10.
You can flash these factory on your device if you wish (assuming you have an unlocked bootloader) but unless you edit the flash-all shell script (Linux/Mac) or batch file (Windows) to remove the “-w” from the update line, doing so will wipe your device completely.
It’s probably best then, for most people at least, just to wait for the OTA. There have been no sightings of OTA updates hitting either device just yet but with the factory images now live it is surely only a matter of days at the most before the roll-out commences. The wait is almost over.
If you do want to flash the factory images or you are a developer and want the you can get them from links below.
