Google posted the Android 5.0.2 factory image for the 2013 Nexus 7 not too long ago. And now, you can download and install it yourself, instead of waiting impatiently for Google to issue the update. This is coming straight from Google, so you have nothing to worry about as far as security is concerned.
The update is for users coming from the LRX22C ROM, so if you’re running an older build, head over to the Google support forums to flash the LRX22C update and then move on to LRX22G. Flashing an update file isn’t usually complicated, but it requires you to wipe data from your device and have some knowhow. So make sure you know exactly what you’re doing before going ahead with the process.
Android 5.0.2 is expected to bring a couple of Nexus 7/Nexus 10 related bug fixes and isn’t available for Nexus smartphones. The Nexus 10 is also expected to receive the update, although the update file isn’t available yet.
