As you can see both have completely different hardware in them therefore they must be treated & flashed differently. What I mean by differently is that roms or rooting for the 2012 model Nexus is different than the 2013 model Nexus. Using wrong roms or root methods will cause you to brick your Nexus.

Reason I rooted my Nexus 7 FW Version:4.1.2 a year back long before latest FW update Kit-Kat is because I wanted to use the Blue globe default browser that pretty much all Android based phones/tablets use. Well the Nexus 7 2012 doesn’t atleast not stock it forces Google Chrome on you.
So I went ahead and only Unlocked bootloader and rooted my Nexus 7 just to get the browser. The good news is if you haven’t rooted or unlockled your Nexus and updated to latest KitKat Version:4.4.2 you can now go ahead and download the browser in google play store. Note:“I did NOT install a custom ROM”. Before KitKat it wouldn’t allow it to install unless you rooted it.
To check what version your Nexus has open settings scroll down to About tablet. In About tablet you will see Android version. If you see 4.4.2 congratulations just go ahead and download the blue globe browser it actually supports almost all plugins. Google Chrome just isn’t that great.
If you have already rooted your tablet on a previous version of Android you will not be able to update your version OTA or by manual install. Not until you first unroot your device.
This is the reason I decided to add this to my blog spot.

The application I used to Unroot is called Nexus Root Toolkit.
It’s the one I used but still scan with AV.

Here is a link on how to Root your Nexus 7 2012 Wifi version.

That is just to root but should also be about same to unroot just look at the Nexus Root Toolkit application when it’s running it has unroot options to select.
If your uncomfortable going ahead and trying to unroot by following NRT do a google search that will give you plenty of results for doing it. That’s why I won’t bother posting another walkthrough for how to unroot your Nexus 7.

With the info I posted and download w a root link you should be well on your way to either rooting your Nexus 7 or unrootimng it to update to latest Android version KitKat V.4.4.2:-)
