This Guide assumes you have the SDK setup and know how to use adb

Download the OTA zip

Rename it to

Move to your platform-tools folder, I have the android studio installed so I put it in /home/MYUSERNAME/android-studio/sdk/platform-tools/

Plug in your Nexus 7 with USB debugging enabled (in Developer options)

open up your terminal and type

adb devices
You should get something like

015d3248d95bea10    	device
Now type

adb reboot bootloader
and you're Nexus 7 will reboot into the bootloader, at which point you must use the volume up and down buttons until the screen displays "Reboot Recovery" in the top right. Now press the power button to reboot into recovery: You will see the Google logo as normal, then a green Android with a red warning sign with an exclamation mark inside.

Press the volume up button and the power button at the same time ONCE (do not hold them down) and this screen will disappear and you will be in recovery. Use the volume buttons to move between options and highlight “apply update from ADB.” and press the power button to choose.

Back to your terminal, cd into your platform-tools directory where your is located, e.g. for me:

cd ~/android-studio/sdk/platform-tools/
Now type

adb sideload
Your terminal should tell you it's sending the update package, and once that's finished your Nexus 7 should begin applying it.


This did not work for me. If you get the message

error: insufficient permissions for device
Then type:

sudo ./adb kill-server

sudo ./adb devices
and you should get a message such a

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached 
015d3248d95bea10	sideload
Now type

 sudo ./adb sideload
and all should go well


After the update has finished applying, you have 2 options: reboot, or wipe cache and reboot. I personally chose to wipe cache to be on the safe side, and your Nexus 7 will reboot automatically after this anyway. You can reboot as normal if you want, however. Simply choose which option you want with the volume buttons and press power to apply.

I hope this has helped the impatient amongst us
