Download ADB tools
Download Android 4.4 for the Nexus 7 - only if you have the current build version JSS15R.
Extract adb tools, navigate to adb-tools folder. In a blank area of the window, hold Shift and right click, select open command window here. Copy the KitKat firmware file into the adb-tools folder and rename it something like: nexus7-kitkat-ota.zip
Get your Nexus 7 into Recovery Mode. If you don't know how, follow these steps:
Turn it off.
Hold down Power and Volume Down button.
Select Recovery mode using the volume buttons, hit Power button to enter.
Once on the Android robot screen, press Power and Volume Up to get into Recovery Menu.
Select ''apply update from ADB'' and hit Power button to enter
Connect your Nexus 7 to your computer with a USB cable.
Go to the Command prompt window and type: adb sideload nexus7-kitkat-ota.zip
Let the firmware install, then restart by selecting ''reboot system now''.
Voila. All done. Check out our article on Google Search and the Google Experience Launcher to complete your KitKat transformation. (This step is also optional as the updates will be pushed out soon too) or just download the following APKs:
Download Google Search 3.1.8 APK
Download Google Experience Launcher APK
