In the main menu, did you select the proper version of your tablet?
The N7 has several variants, such as nakasi, Nakasig, and so on.
You need to know your version, such as 'GROUPER'
Your best bet is to first UNLOCK the bootloader, then attempt root.
You will notice several menus pop up, just follow the steps as they appear.
Once you acquire the unlocked notification on our device, then proceed to root your tablet in the next step.
NRT is easy to follow along with, and Wug made the process quick and painless, all you need to do, is follow the instructions and you should have an unlocked bootloader and root access.
Warning, many versions of apps like rom Toolbox give a false 'unrooted' indicator, and if you use Titanium Backup, you may get that same notification on that also, simply download the latest Superuser from CHAINSDD from the play store and grant access through SU.

I already unlocked it and device is nexus 7.
