Finally, all the Official Android 4.4 OTA Update zip files are available for download for all the Google Nexus devices.
If you’re tired of waiting for Google to push the Android 4.4 KitKat OTA notification to your Nexus 4, 7 or 10, then you can flash the full OTA zip files yourself via adb sideload or using a custom Recovery image such as CWM or TWRP. This type of process will take only several minutes to complete.
The Nexus 4 KRT16S OTA Update zip file measures 239 MB, while the other files for the 2012 Nexus 7 3G and Wi-Fi, 2013 Nexus 7 LTE and Wi-Fi are measuring somewhere around the same size. Flashing the OTA Update manually doesn’t require you to have a rooted or an unlocked bootloader. Installing the file will not wipe your device, as a factory image installation does.
Android 4.4 KRT16S OTA zip files will not install in case you’ve changed in any way the system partition. If you own a Google Nexus 4 and you cannot flash the OTA Update because of such system errors, then you can use our guide here and learn how to install the factory image here. Users with bootloader locked devices will lose all data in the process, but if you have an unlocked bootloader then you can go around ‘data wipe’ and flash it without losing files.
Download the OTA zip files for your Nexus device, then put the file in the Android SDK folder> Platform-Tools, run a command prompt and use adb sideload to push the files. Remember that your device has to be in Bootloader Mode and the USB Debugging option enabled in Settings.
If your device is rooted but it runs on stock Android ROM, then you can simply download the OTA zip file, then move it to your device and then flash the file just like you would do with any other ROM via stock / custom Recovery.
