I have just rooted a Nexus 7 with Android 4.2.2. I now receive a notification for system upgrade to 4.3. I don't want to do this, probably ever, as I want to keep 4.2 for app testing purposes. In Settings > About tablet > System updates and in there it says:
Android System 4.3 Update
[Restart & Install]

How do I prevent the upgrade, ie how to I get rid of that Restart & Install button and to I prevent future upgrades & notifications?

    I don't know the answer to your question but Google provides system images for testing purposes so that you can restore to any supported Android version for your Nexus device: developers.google.com/android/nexus/images Commented Aug 29, 2013 at 19:30

    @wawa The system images will try to upgrade again.

Go to this XDA-Developers thread and follow the instructions. You have to download an APK from there and install it as a system app.
