Google has started releasing Android 4.2.2 for its Nexus 10 tablet, Nexus 7 tablet and the GSM Galaxy Nexus. Google is sending out the update OTA but if you're too impatient and want it now, you can choose between two ways to install it manually.

As with the Nexus 10, you'll need to be running stock JOP40D on your Nexus 7 in order for this to work. You can check the build by going to the Settings app, then tap About phone, scroll down to the build number and you'll see if your Nexus 7 is on JOP40D. If it is you can now proceed to download Android 4.2.2 for your tablet.

Once again, Droid-Life has posted detailed instructions on where to get Android 4.2.2 for the Nexus 7 and is providing two different methods of installing Android's latest update. You'll need to download the zip file here and proceed to installing it via Custom Recovery or Without Custom Recovery.

Instructions (Custom Recovery):

1. Download the file noted above to your internal storage.
2. Temporarily flash a custom recovery if you haven't already.
