nexus 7 - Can 4.3 update notification be removed?

I just got a new 2012 Nexus 7 16 GB Wifi tablet today & setup it up. It is originally running 4.2.1. In a few minutes, I got the message that System update downloaded (4.3 Jelly Bean) & that I should touch to install it. Can I make the notification about the system update downloaded disappear? Unlike other notifications, this doesn't seem to go off when I try to slide it to the right.

Reason: There are various reports that screws up your Wifi - and my Nexus 7 is Wifi only (no 3G). I don't want to risk to install this by accident.

Update: I think another new update arrived and was downloaded (probably KitKat 4.4.3). And the notification showed up and didn't disappear even if Show Notifications was unchecked in Google Services Framework. Had to this uncheck 'Show Notifications' in 'Google Play Services' to make the notification disappear.

Answer

Try disabling the notification then restart your tablet and see if it reappears:

Go to Settings > Application Manager > All > Google Services Framework and then uncheck "Show notifications".

Are you rooted? If so, and if disabling the notification doesn't work, try freezing or uninstalling the update apk:

Use Root Explorer or ES Explorer and go to phone memory system/app/ and delete or rename UpdateCenter.apk. Alternatively, you could freeze this application in Titanium backup application.

You could also try modifying your build.prop file to trick the tablet into thinking it's already updated (root required). This was also mentioned in an answer to a previous question.

To prevent the update notification, you will probably just have to change the build.prop values. So, change:

ro.build.description=voles-user 2.2.2 FRG83G 91102 release keys to

ro.build.description=voles-user 2.2.3 FRK76 185902 release keys

and

ro.build.fingerprint=verizon/voles/sholes/sholes:2.2.2/FRG83G/91102:user/release-keys to

ro.build.fingerprint=verizon/voles/sholes/sholes:2.2.3/FRK76/185902:user/release-keys

Note that this quote is referring to old software versions and that the ro.build.description and ro.build.fingerprint lines will need to look different for you than those quoted. Check out this answer for more information on making such a change.

For me and my 2012 N7 I just lived with the notification until I couldn't stand it any more, then I just upgraded anyway.
