Change these things(bottom of post) in build.prop. Go to the cache and delete the update that has probably already been downloaded. Reboot. The notification should still be there, hit it, it will run and fail and won't come back after that and won't download any more updates. You basically just need to clear out the notification that's already there after you change the build.prop. Otherwise change build prop after a clean install and you'll never get notification in the fist place.
