Root Nexus 7 on Android 4.4 KitKat

To Root your Nexus 7, you will need to unlock your bootloader and Install CWM recovery. To do so for Nexus 7 2012, follow this and for the Nexus 7 2013, follow this.

Well, most of us here would prefer this! Yes, to root your Nexus 7 running the latest, full-featured version of Android; KitKat 4.4. Its because of talented developers like Chainfire, that we’re able to take the pleasure of Root access on our Android devices, just in a few countable steps. Once you have successfully flashed the factory image, you can perform the further steps to gain root.

  1. Download the latest SuperSU flashable package: Download
  2. Connect your device to the PC via USB cable and transfer the UPDATE-SuperSU-vXXX.zip (here XXX resembles the latest version) to an apt location on your device’s storage
  3. Disconnect your device
  4. Power off. Now press Volume down and power button altogether until you see the bootloader screen. Use the volume (+ or -) keys to highlight Recovery Mode and select it using the power button. The device will boot itself into CWM recovery.
  5. Tap on Install zip from sdcard > choose zip from sdcard and select the UPDATE-SuperSU-vXXX.zip (here XXX resembles the latest version). Tap on Yes, when prompted to initiate the flashing process.
  6. Once done, tap on Reboot System Now to reboot your device.

Enjoy the taste of KitKat on your Nexus 7 along with Root access! Stay tuned! If you have the Nexus 10, the guide for the same is coming too.

  1. Thanks for the reply. Yes, I got it now. Extracting the contents as I wrote above did work, I just needed to extract a second time for some reason. Anyway, it’s OK now. It was probably something strange at my end. Regards.

  2. Guess you got it already. Apologies for being late.
    Everything seems right at your side but I’m kind of worried for the 2nd question of yours. I have the same .tgz file and once I extract that, I get a folder holding all the files, instead of what you stated. May be your download was left incomplete. The same happened to me too at the starting. So, I advice you to use another Download Manager (if any) or browser.

  3. Hi There,

    When I try this, I receive an error saying “‘fastboot’ is not recognized as an internal or external command, operable program or batch file”. Do you have any idea what this means? I believe I installed the Android SDK in the past to get my Nexus 7 on 4.3. Perhaps it is an issue with drivers?

    Also, in step 3:

    “Power off the device. Press and hold on to the Volume down and power key altogether until you see the bootloader screen. This screen is what we know as bootloader mode or fastboot mode.”

    I have ClockworkMod installed. Do I boot into ClockworkMod then choose something? Or do I simply have to be at that page where I can select ‘Start’, ‘Restart Bootloader’ or ‘Recovery Mode’?

    Finally, the link for the 2012 Wifi downloads a .tgz file. When I unzip that, I get a .tar file. When I unzip that, I then get a folder with contents. Is this the correct process? The instructions simply state “Extract the contents of the downloaded file to the desktop. So now you have a new folder viz nakasi-krt16oholding all the required files.”. Perhaps this should be clarified a little to be more specific.

    Thanks in advance 😀
