Sorry I got tied up. If it doesn't list any devices you don't have adb set up yet. First go into settings on your device, you have to enable developer options by going into about tablet and scroll down to bottom and tap build number about seven times, it will tell you when your getting close. Then go into developer options and enable android debugging. Now plug your tablet into computer and you should get a pop up asking you if this computer is ok for debugging or something like that so enable it or say yes what ever the option is. Sorry doing this from memory so can't tell you exactly verbatim what those popup prompts say. Now for debugging on the computer end. I don't know how long you've had the sdk on your computer so just make sure its up to date by opening the sdk manager and check for any updates. In order for adb to work with 4.2.2 you need the latest tools. Ok so with all that done now open a cmd window and navigate to your platform-tools folder and try adb devices again. you should get a read out of some numbers after that. Let me know if that works and we can proceed. Good luck!

This helped me..Thank you underwaterjr:laugh:

Dumb question... read this...

Flash Su

1. Go back by pressing power button​
2. Install the zip in the sdcard​

Reboot and your device is now rooted!!

But when I look at SuperSU it clearly states that it requires root to work.

How can flashing this per the instructions above provide root when the developer says root is needed to use it?

What am I missing?

Thanks for humoring the ignorant (me)... !!

It means:

After you have flashed the custom recovery of your choice, acquire the SuperSU zip file from this site, and place this zip file in your device's internal memory.

There should be an option in your custom recovery to flash a zip file. Pick this option and direct it the location of your SuperSU zip file you placed in your device's internal memory.

Once successfully flashed, reboot your device and go into your app drawer. SuperSU should be in there.

So I got the new Nexus 7 today. CWM probably doesn't support it yet right? Is my only option to just unlock it at this point? I imagine I have to wait for a new root method as well thanks to 4.3.

Yeah, unlocking it would be the only thing you could do until they come out with CWM for your device. CM is coming out for the device really soon since they already have it booting on the other nexus devices. I'd Just wait until then.

Nexus 7 Root Question

Possibly the wrong area to post this but...

I have a Nexus 7 (2012)
running 4.4.2 - Build KOT49H

Is it possible to root? I've looked at numerous sources for guides and information and I haven't found anything solid yet.

I'm no stranger to root and custom ROM's & Recovery

I just want to make sure I do things the correct way if it's at all possible?
I'd like to be able to root and install twrp recovery. I'll keep the stock ROM I actually quite like it, it just needs tweaking

Any help would be much appreciated.
Thanks all & Merry Christmas!

Not yet, but I'll give it another look tomorrow at some point and let you know what I find.
I'm not sure if this thread is just stale or it's just not possible...
Check back soon :good:

Sorry for not being active here, this is a thread back from I/O 2012 when we first got our Nexus 7s. If you have the og Nexus 7, then this will work. It may be a bit outdated, but just get the new cwm recoveries as well as a new super su package.

After a lot of consideration, decided to sell my Samsung Galaxy S 4, and purchase a Nexus 5. So waiting for that to arrive :victory:

Drawing my attention back to my 2012 Nexus 7.
Running 4.2.2 KOT49H and wishing to root, I've found a few methods that should solve the problem...

http://www.teamandroid.com/2013/12/10/root-nexus-7-android-442-kot49h-kitkat-install-cwm/2/

or

http://www.ibtimes.co.uk/nexus5-android442-kitkat-kot49h-root-update-release-529012

My only problem here is I'm not familiar with CWM, I've always used TWRP...

Does anyone have a guide for this build using TWRP?
More to the point, has anyone rooted the device on the KOT49H build?

Yes I've rooted using the same procedure as in your first link from team android. Do everything the same except just put the full filename for the version of TWRP that you downloaded and placed in platform tools directory after the command "fastboot flash recovery"

Did I just break my nexus? had it for an hour :c

did fastboot oem unlock and flashed CWM for Flo, and didn't have SU on my sd, when i press reboot it asks:

"The stock rom may flash a stock recovery, fix?" and i clicked no, then it says "do you want to root from /system/xbin/su"? i click no because i have not yet installed SU to my /sdcard. Now when i boot I'm stuck on the X screen.

Please help ASAP:crying:

Will this work on a 2013 model? I just decided to upgrade because I found a deal for $130 and figured I can get at least $50 for my 2012 model. I do have access to a windows netbook that's collecting dust in a corner but, would prefer to use my ubuntu desktop with adb and fastboot installed from the repos. Hate to bump but, I'm interested in doing this when I wake up in the morning. Will this work for the new model?

Just wanted to say thanks, I have been able to root and install clockworkmod on my Nexus 7 2012 which is running much better with Lollipop 5.1.1
If followed the first post but I could not flash SuperSU zip because the oem unlock command had wiped all data.
The device reboot and took about 5 minutes to load into Lollipop, be patient.
A free root checker from the app store confirmed the device was rooted but SuperSU app said there were no binanries which I guess is because I had not yet intalled the zip file.
Put the superSU zip back on the Nexus and did a checksum check on the file.
Anyway getting back into clockworkmod meant I could install the superSU zip file. (though I had to use fastboot flash again as CWM had not stuck).
Job done, Nexus is rooted and SuperSU is happy.
Thank you., I am glad I went for the manual method using Androind-SDK tools as I had a better handle on what I was doing.
Off to build it now with the KitKat gallery apk file I found and other nice things that rooting brings..

    I found less detailed guide on rootzwiki created by birdman, but i decided to repost it here in more detail.

    * Disclaimer: I do not take any responsibility for anything you do to your phone, whether be brick, break, or somehow mess it up.


    Requirements
    1. You must have the sdk installed and you are able to access, and use adb and fastboot.
    2. You must have debugging enabled on your Nexus 7.
    3. Download Su here (Chainfire's thread for supersu) (Thanks Eric_Eric_Eric)
    4. Download CWM here. Scroll down to Nexus 7 and choose whether touch or regular.

    Pre-Steps
    To make this easier, you should put the su zip on the sdcard for later.

    1. In terminal, cd to the directory you have your sdk in. Then cd into platform-tools.
    2. Type adb push path-to-zip/JB-SuperSU.zip /sdcard


    Unlocking Your Nexus 7

    To unlock your device
    1. cd to platform-tools
    2. Reboot to the bootloader - adb reboot bootloader
    3. Unlock your device* -
    fastboot oem unlock
    *You will have to accept and erase all the user data on the tablet.
    *You must run this as sudo in Linux


    Flash Clockwork Mod Recovery
    (You're still inside the bootloader)

    4. Flash CWM -
    fastboot flash recovery path-to-img/CWM-grouper-recovery.img​
    5. Make CWM Permanent -
    1. Boot into recovery​
    2. Go to Mounts and Storage​
    3. Mount /System​
    4. Type in Terminal*​
    adb shell
    cd /system
    mv recovery-from-boot.p recovery-from-boot.bak

    If your having trouble gaining shell, try "adb kill-server" then "abd start-server". Couple of my friends had this problem, and this should hopefully fix it.
    * For some people, it has been reported that you don't have to replace recovery-from-boot.bak. The flash is enough to make the recovery stick.

    Flash Su

    1. Go back by pressing power button​
    2. Install the zip in the sdcard​

    Reboot and your device is now rooted!!

    For anybody having trouble trying to use fastboot and come up with a no-permissions error or adb ????????? problem, I created a guide to fix the problem here: [GUIDE]Fix Fastboot and USB

    I do not know of a driver right now. I'm using Ubuntu so I guess it just worked for me. If i come across any drivers, I'll post them in the thread, but until then, i'm not too sure :/

    sorry man. :(

    If you find them, please tell me so i can post them to help others with the same problem.

    Though, i would think that windows would pick it up automatically being that it's just adb drivers.

    When I updated the Android SDK it also had an update for the "Google USB Driver". When I look at this driver it now includes the Nexus 7.

    I have attached the new Windows drivers for those who don't have the SDK installed.
    EDIT: It appears there are some problems with XDA uploads lately (at least for me) so I have shared it here

    what would unlocking do? isnt that for phones so you can put other simcards??

    It is technically "unlocking the boot loader" but unlocking was short and sweet for the title.

    Umm, this no way to do this without adb. I'm working on a one click script which i will be posting later. I am currently in IO Sessions and should have it in the next couple of days.

    But an answer, again, no, there isn't. You need to download the sdk, and install the tools. then just cd to platform-tools, and use adb like i said. If your in windows, use adb.exe then the arguments, but if your in linux, just use ./adb. Same thing with fastboot.
