First of all, I am in no way responsible for anything you do to your tablet period.
I have seen a couple of people asking how to return the Nexus 7 to stock after it has been unlocked, rooted and so on, so I figured I would write a quick guide as its super easy to do. Also, please make sure you make a backup of anything you don't want to lose. This is important.
1) Make sure you have your ADB and Fastboot drivers installed and working.
2) Download the factory image for the Nexus 7 here
3) Unzip the factory image into the same directory as your Adb and Fastboot drivers.
4) Plug in your device. With the device on the home screen, type "ADB reboot bootloader" or if your device is off, press and hold both volume keys and press the power button. After holding all three buttons for a couple of seconds, your bootloader should launch.
5) This should reboot you into the bootloader. Now type "fastboot flash bootloader bootloader-grouper-3.34.img"
6) Next type "fastboot reboot-bootloader"
7) Now type "fastboot -w update image-nakasi-jrn84d.zip"
8) Optional: If you would like to relock your bootloader for warranty purposes, make sure you are in your bootloader screen again and type "fastboot oem lock"
9) I don't remember if the tablet automatically reboots at this point but if it doesn't just type "fastboot reboot"
That should do it. You should now be on stock Android 4.1 and ready to send in your tablet for warranty purposes.

I'm not sure what happened but the last thing I did was flash a recovery then a fastboot reboot. After that only Google logo no matter what I do. Actually had to pull back cover off and pull the battery cause it wouldn't turn off any other way
Went back through my terminal session and the exact commands went like this.
./adb reboot bootloader
./fastboot flash recovery ~/Downloads/openrecovery-twrp-2.2.1-grouper.img
./fastboot reboot
thats it.
