So I just picked up this device couple days ago. It's running 4.4.2
This has surely been asked before but how do I root this build? I only found TUTs for 4.3 here on xda

Thanks

PS. This is my first nexus device

Fastboot commands to unlock bootloader and install TWRP. Then flash a root zip.

I know the BL is unlocked cause I see the lock symbol at the Google screen
I tried both cwm and twrp

It sounds like you still have the stock recovery installed instead of the custom one you're trying to flash. What command are you using to flash the custom recovery? It should be:

fastboot flash recovery [insert recovery filename here].img

Then, use the volume buttons to boot into recovery from the bootloader. Your custom recovery should boot up.

Yeah I used that command. I have used it before on my Optimus 3D

Are you using the proper TWRP? You may try the command again.

Edit: In order to flash you have to CD from a folder containing adb.exe and fastboot.exe. Otherwise nothing will flash. Download this folder https://docs.google.com/file/d/0B_nizg6yUZ0NbWNvZHFMR1h6LVE/preview?pli=1 and Stick TWRP in the folder.

@lzzar Glad you got it figured out.

Short story for anyone who might find this thread after seeing the Red Triangle.

I saw an article on Android Police that there was 32gb refurbs for sale for $170. So, clearly we (XDA members) are not the same as normal users when it comes to troubleshooting and fixing problems. So, I bought my 2 sons 1 each and my wife 1 as well. While my sons are very young (single digit ages), I've taught them how to run code. The N7's arrived yesterday and after they went to bed, I fired up the computer and had all 3 tabs going at once updating from 4.3 to 4.4.2, charging, downloading,....

Unlocked all 3 Bl's and proceeded to install TWRP and ROM/Kernels. Point to remember is that I had too many things going on at once. On the very first recovery.img flash, I got the laying down android with red triangle. Flashed the recovery.img again and again the red triangle, all the while I was downloading ROMs and Kernels on my PC.

Then I realized what I was doing wrong. After flashing the recovery.img, I booted into the OS, then powered off and used the key combo to boot into recovery. Wrong!! What step did I miss? After flashing fastboot flash recovery recovery.img, I had forgotten to Volume up and boot into recovery from straight from there.

Once I realized my blunder, I was much happier. After that, it took me under an hour to install recoveries on all 3, flash ROMs and Franco r13, boot and reflashed SuperSU. Too many things going on at once and maybe a few too many drinks as well.
