Some of the Google Nexus 10 and Wi-Fi variants of Google Nexus 7 (2012/2013) are still waiting to receive the latest Android 4.4 Kitkat OS update, which was previously a Neuxs 5 exclusive.

Since Google is taking a long time to roll out the updates on each and every handset, some of the Android enthusiasts have come up with a method to install Android 4.4 Kitkat on the device manually.

Following are some of the steps, which would help the users to manually install Android 4.4 Kitkat OS on their Google Nexus tablets (Wi-Fi variants only).

What You Need

  • A Wi-Fi Google Nexus 7 (2012/2013) or Nexus 10 with drivers installed.
  • A microUSB cable
  • Windows PC/Linux/Mac
  • A Nexus 7 (2013) running the latest Android 4.3 jelly Bean with build number "JSS15R", Nexus 7 (2012) and Nexus 10 with "JWR66Y" (must be running the stock ROM, not a custom one).
  • Latest Android SDK version. Check fromhere.
  • Zip file containing the Android 4.4 Kitkat OS for the device.
  • Clickherefor Nexus 7 (2012).
  • Clickherefor nexus 7 (2013).
  • Clickherefor nexus 10 file.

(Files have been taken from Google servers and are safe to run.)

  • Laptop connected to a power point or fully charged. Tablet also fully charged.
  • Create a backup data before beginning (Optional).

This method will not clear any data and the user shouldn't lose any apps or settings.

How to Flash the Update

  • Go to Settings > About Phone > Tap on Build Number several times till the message shows "You are now a Developer".
  • Exit from "About Phone" and find the "Developer Options" settings. Enable USB debugging.
  • Connect the tablet to the computer and unzip the Android SDK which should have been already installed before connecting the device.
  • Find the related Android 4.4 Kitkat ZIP file and rename it to something easy, for instance "Kitkat". Move the file to Android SDK in the folder "Platform tools".
  • Power the tablet back on by holding Power and Volume Down buttons at the same time. The user will then witness the fastboot mode.
  • Click Volume Up button until it shows "Recovery Mode". Press the Power button to accept. A Google Logo would be shown followed by an Android with the words "No Command Written". Connect the tablet to the computer via Micro USB.
  • Hold the Power button down first, and then quickly hold the volume up button while holding the power button. The user will then see the Android system recovery files.
  • Use the volume down button to scroll down and hit the power button on "apply update from ADB" to accept. The user will then see this "Now send the package you want to apply to the device with 'adb sideload..."
  • Return to the computer > Open folder containing Android SDK and open the "platform-tools" folder. If the user is using Windows Vista/7/8, hold shift and then right click on the empty space. The option "Open command window here" can be seen. If the user is using Linux or OSX or Windows XP, open a command prompt and navigate to "platform-tools".
  • In the command window, type "adb sideload Android KitKat", without quotation marks and substituting Android Kitkat for the renamed ZIP file mentioned above.

Note: Remember to add the extension ".zip" to the end of the file name for the zip file.

  • Let the device install the update by itself followed by booting up of the device by the user.

Same steps can be applied for Google nexus 4, Nexus 7 (2012) 3G and (2013) 4G. The following ZIP files can be downloaded from here.
