Google's servers has rolled out the official Android 4.1.2 with landscape support. If your Nexus 7 is running Android 4.1.1 build JRO03D, you could use ADB sideload method to flash it to the latest OS version or do that directly with custom recovery.

* First download the zip file that is about 32Mb on your computer.
* Power off your device and connect to your computer by USB cable. Hold the Volume Up, Volume Down, and the Power Button to get fastboot menu, navigate to the Recovery Mode using volume button and confirm that by pressing the Power Button, then press Power + VolUp and select "Apply update from adb".
* Make sure your PC has enabled adb. Go to your adb directory, right-click in the window , and select "open command prompt here" and type in the following commands
 adb devices
 adb sideload {location of file}
I put the file on C:\update\ota.zip, so I type in "adb sideload C:\path-to-ota\ota.zip". If the processing is finished, it will display "sending: 'sideload' 100%". Now reboot again.
