Lots of people are having problems with the Android 4.2 update. They lose root or they can't get back into recovery. So BEFORE you flash 4.2 or if you already did and are having issues. Download this utility I whipped up. It will flash (or reflash) the 4.2 update (Including system, kernel and bootloader). It'll flash the latest 4.2 compatible ClockworkMod Touch Recovery. And then it'll get you all set up to re-root your N7 within the latest CWM. Instructions are included in the README file. PLEASE READ IT!

You DO NOT need to be on a stock rom to run this and it will NOT erase your data. But it is recommended when you get into CWM recovery for obvious reasons.

If anyone is having any issues and you get caught at the Google splash screen. You can use Power, Vol - to hard shut down the tablet, then Power, Vol +, Vol - to get into the bootloader. From here you can install the factory images from google. Once you're back up and running, you can run this tool to gain root and CWM back.

Updated 11/14/2012: Replaced SuperSu.apk with the latest version designed for 4.2
Updated 11/14/2012 14:41EST: This package will now contain 3 different runme files. One of them will not erase your data, one will erase your cache only and the last one will erase your data and cache. It seems people coming from some roms are having bootloops or hangs because of a lack of data wipe. You can attempt to run the one with no data wipe, but if you run into trouble, try one of the others. Some have made it through with only a cache wipe. See what works for you.
Updated 11/14/2012 16:53EST: Removed full data erase option as I forgot it will erase your SD card and therefor erase the root zip before it gets a chance to flash. There is only 1 runme file now and it will erase your cache, but leave your data alone. If you're having problems, or you want to avoid problems. Erase your data in CWM before you flash the supersu zip included in the package.

For Now - Windows ONLY, Sorry.
Linux version, on the way

Anyway:
Download and PLEASE READ the Read Me!

Ok, I tried this and got stuck on the boot screen. Guess Ill try it again. I was on AOKP before.Can I just run this from there? I should I have wiped before?

Im not getting something. After I press runme.bat my Nexus goes to clockwork recovery, its not touch, I have to choose from options like Start, Recovery Mode, etc. It doesnt match the instructions. Im super confused, any help?

Ugh. now my device is stuck at the google start screen, and not going anywhere. Android is too complicated sometimes for dumb people like me...

Its booting you in fastboot. just follow the instructions in the window that comes up when you run the runme.bat.

When it boots in fastboot just hit the space bar. It will take a couple times of hitting the spacebar before you reach the CWR stage where you flash the PlaceMeOnYourSDCardSuperSu.zip

When I click runme, it opens up the cmd window, starts the daemon, and then just sits there with a blinking cursor. Tried this few times already, nothing is happening.

EDIT: My nexus 7 is connected and has usb debugging turned on.

Do you have ADB set up on you computer?
Did you make sure you have USB debugging selected on your nexus 7 in developer options?

Figured it out. My computer recognizes the Nexus 7 as a portable device, but not recognizing it in the usb debugging mode (shows "Nexus" under Other Devices with a yellow triangle). Tried to update the driver, but it failed.
