Hmm...First I would try to re-download cf-auto-root just in case something got corrupted. Then be sure to re reboot into bootloader mode before you try again.
If that doesn't work, try WugFresh's toolkit. Unfortunately it is 10x the download size...

Re:Rooting Kit Kat
I have a Nexus 7 (2013) model after reading up on it and playing around with it. I sold my Nexus 2012 and decided to purchase the new model. I installed all of the updates then manually updated to Kit Kat. In regards to rooting I just used Wug's Toolkit and it worked perfectly I was able to re-root my device and install the TWRP Recovery.
I used Nexus Root Toolkit 1.7.6 to root push the official kitkat factory image to my Nexus 7, and right after that, root + flash TWRP. Took no time at all and was painless. Just ensure you allow the toolkit to download the secure boot .img and custom recovery for the device when prompted.
Try it out. http://www.wugfresh.com/nrt/

This is what I did, sideloaded with TWRP, and it worked like a charm.
I can confirm last 5 replies.
if you are already unlocked, all you have to do to root any nexus device is flash a custom recovery then flash supersu. and if youre not unlocked already. all you have to do is unlock your bootloader, flash a recovery, then flash supersu. thats all, for any nexus. nothing complicated needed, ever. no root toolkits are ever needed unless you want to make sure that you wont learn a thing.

I lost root after manually updating to 4.1.2 by flashing the zip.
I tried re-rooting but nothing happened and it would just boot back to system.
It is still unlocked though.
Please advise.

You can use WUGs tool kit to root after 4.1.2 update.
For version, just pick custom ROM (JB).
Search for that thread and follow his second....super easy.

Thanks. Yes Wug's toolkit is easy to use. Unfortunately that's one of the first things I tried and didn't work for me.
What ended up working was using Wug's to UNROOT, then unlock and re-root. For some reason that worked. Also fortunately I had a feeling I needed to backup my TWRP backups onto my computer as the Nexus 7 was COMPLETELY wiped after re-unlocking. After this was all done, I moved my backups back to my N7 and restored. Back to 4.1.1 for now. Whew!
didn't work for me either, I could not get ANY custom recovery images to successfully boot on the new bootloader and 4.1.2. Going back to 4.1.1 allowed root again.
Big waste of time going back to stock, locking, unlocking, sideloading 4.1.2 then trying to root.
Had to wipe once more, go back to stock, unlock/lock, root and leave it on 4.1.1
No idea how people are getting custom recoveries to boot on 4.1.2, mine will just restart itself within about 10 seconds of trying to boot an image.
Wug's toolkit makes a folder called ! Ready to flash ...
You will find support su and busy box there....boot to recovery flat the two zips and it roots...
If you did a full wipe they may not be there anymore...
Run the Wug script, when it boots to recovery, install the two zips manually.

Why not try before you give up? Nothing I suggested is even remotely challenging.
With your tablet booted normally plug it in to your computer and copy the superuser zip in my previous post to the Download directory on your Nexus 7 from Windows.
Judging by the first provided screenshot I can see that option 6 in that toolkit is for flashing recovery. Why not try that?
As far as how to install the zip from ClockworkMod (CWM), there are literally hundreds of threads and YouTube videos that will show you what to do. The better option is to spend a few minutes (literately. It only takes a few minutes.) to learn some basic fastboot commands. If you're willing to learn there are many people who will help.

But in the Nexus7 ToolKit can be done but is ClockworkMod must first rename (recovery restore files) but with da only when I have ROOT.
And why unnecessary to install CWM and resolve other problems I'll eat a connection. If "simply" can I ROOT who create me rich enough.

Choose #1 in your first screenshot.
After you install CWM make sure you boot recovery before a standard boot. On rebooting from CWM it will say something like "ROM may flash stock recovery on boot." and prompt with yes or no. Choose yes - this renames /system/recovery-from-boot.p and prevents the ROM from restoring stock recovery.

I tried quite a few times to root my Nexus 7 with the Nexus 7 toolkit, it hung every time when it was supposed to be installing SuperSU and BusyBox.

I'm also having this same problem but here's my story:
Using the Nexus 1.5.4 Toolkit, I Unrooted + Flashed jzo54k, success. I locked OEM, success. I unlocked again, success. Then I ran the root process again, and it keeps freezing at the android recovery screen. Following the prompt in the toolkit, I walked away for a few hours hoping time would resolve the issue.
If you're wondering why I unlocked + rooted, and decided to unroot, lock, unlock, and root again, its because I'm super-noob to anything android related after version 1.5, I wanted to learn the processes after I found out I was having troubles with certian things after my Nexus 7 updated from 4.1 to 4.1.2
I am having the same issue as you. 4.1.2 is not rooting for me. I can't install CWM or TWRP because it needs to rename recovery files, and to do that you need to be rooted. If I boot in recovery I always get stock
Having the same issue with a stock 4.1.2. I can unlock no problem but I cannot get it rooted. Everything appears to have worked, but it is not rooted. If I revert back to 4.1.1 I can unlock, root, etc. without issue. I was able to root 4.1.1 and use the root keeper app to then update to 4.1.2 and I was rooted still. However, it would not let me install CWM or anything. ROM Manager says it was installed, but booting to recovery always too me to stock.
Any ideas?
Can you point me into the direction to downgrading?

I used Nexus Root Toolkit v1.5.4 and selected the "Flash Stock + Unroot" option. When prompted I choose the default 4.1.1 option and away it went.
To root my 32Gb on 4.1.2 I had to unlock the boot loader, flash the boot loader back to version 3.34, and then I successfully rooted using the nexus 7 toolkit.

My 7 is unlocked and rooted, using Nexus Root Toolkit. I did an OTA to get to 4.2.1 some time ago and that went well. Root and unlock persisted. I am now getting OTA options for 4.2.2 from the System menu. First time I got and error in Android's belly. I restarted and was still in 4.2.1. System then said that I was up to date. A week or so later System told me again that OTA was available and I got the same result.
Any suggestions as to how I can do the update?

You have two choices
1. Flash the stock 4.2.2 image using fastboot from here https://developers.google.com/android/nexus/images
Or
2. Flash this in CWM recovery (note this link is for the wifi model) http://android.clients.google.com/p....signed-nakasi-JDQ39-from-JOP40D.6ece895e.zip

Search this forum for "OTA debugged"
There are only a few threads - read them all before you take any action.
This particular problem appears to be caused by StickMount.
You don't need to delete everything, nor do you need to flash the ENTIRE stock image - only the boot.img and system.img (via fastboot) without doing a factory reset or any other wiping.
This will unroot the ROM, and (of course) prevent StickMount from working. So you should over flash a SuperSU root kit afterwards (via custom recovery).
This very same problem may recur on the next OTA - so for goodness sake's, make a nandroid backup before you re-install StickMount and give it root privileges.

Sorry for being a numpty... can someone put the above into a mini step by step guide for me.. I'm stuggling with the terminology.
I rooted my Nexus and have since forgotten anything techie regarding it. I have StickMount and cannot update to 4.2.2..
How do i flash boot.img and system.img via fastboot, where do i get these files from, what versions etc do i need? And over flash SuperSU root kit?
What is OTA?
Basically, I think i need a newbie guide. I am techie enough to achieve most things normally.. i just don't know the android system at all, and what i did know to be able to root it i have completely forgotten!
Any guidance would be very much appreciated. Cheers.

You don't need to flash the stock image and lose your data, but even if you are on stock 4.3 you still need two things: stock recovery (if you don't already have it installed) AND you need to unroot! Being rooted will throw the Status 7 error.
Here's what I did:
First flash the stock recovery for JWR66V in fastboot.
Then use the "Full unroot" option inside SuperSU.
Apply the JWR66Y update using ADB sideload.
Then reinstall TWRP and install UPDATE-SuperSU-v1.51.zip using TWRP.
After rebooting you may be surprised to see that the SuperSU app needs to be installed again (seems to be a quirk a lot of us are having). Just head over to Google play and after that all should be good.

Check out this thread. I flashed the Grouper.zip file, which is the OTA modified by commenting out the validation check that results in the Status 7 error. I copied it to /sdcard along with the Supersu 1.51 zip. The ota flashed perfectly using TWRP recovery. After booting and going back into TWRP, I flashed the supersu1.51 and regained root. You do not need to unroot or flash stock recovery to get this update. No data loss. I'm stock rom & kernel, rooted with TWRP recovery.

You won't lose data if you repeat the steps I took. However since you are asking how to flash a recovery in fastboot I would seriously be careful and do a bit of homework on how fastboot works. All the instructions you'll ever need can be found by searching xda. It really isn't as daunting as it sounds but you definitely need to understand how it works before trying it.
Or you could try the link that Groid posted if you aren't concerned about skipping the validation check. The process is definitely is simpler if you're "new to all these things".
I'm not opposed to using WugFresh's toolkit, he's a brilliant developer, but it's never a bad idea to learn about what happens in the background and see it with your own eyes.

Hi, rdefino...
Yes... don't use a toolkit. Use fastboot instead. It's much easier, and less prone to error.
Rooting the Nexus 7 is relatively straightforward...
-----------------------------------------------
1). Unlock the bootloader (I assume you've already done this).
2). Fastboot flash a Custom Recovery... with fastboot flash recovery name-of-recovery-file.img.
- Custom Recoveries available here...
- TWRP for 'grouper'
- TWRP for 'tilapia' or alternatively,
- CWM versions for both 'grouper' and 'tilapia' - it's important you get the right version for your device.
3). Boot into that Recovery, and flash Chainfire's SuperSU root updater.
4). Reboot, and you're rooted.
-----------------------------------------------
Takes about 5 minutes.
Good luck.

Ged.

Nexus root toolkit 1.7.2 already support 4.3.
Your problem may be due to the toolkit cannot download the needed files to root.
Try to run toolkit again and make sure the updater successfully download all the files needed.

There are some ways to root the Nexus 7. And the toolkit was made to make it easy.
Furthermore, I can root my Nexus7 without flashing custom recovery. This way I can OTA update (if any) without falling back to stock.
