On Thursday, Google announced Android 4.4.1 and it began rolling out to various Nexus devices. We also posted the download links for the Nexus 7 2013 LTE and the Nexus 5 for those that are impatient for the OTA to come through. Now we've got our hands on the Nexus 7 2013 WiFi's update. This one is about the same size as the OTA for the Nexus 7 2013 LTE and the Nexus 5. Weighing in at about 52MB in size. We've got the download link down below as well as instructions on how to sideload it onto your device.
To install this update, all you need to do is simply download the update on your computer. Make sure you've got the Android SDK installed and open up a command prompt window inside sdk/platform-tools. First use the "adb devices" command to make sure your device shows up. You should see it show a serial number and "device". If it says "unauthorized", you'll need to go to your Nexus 7 and authorize it, which is very simple and easy to do. Then type in "adb reboot bootloader". Once you're rebooted, you will need to use the power and volume buttons to boot into recovery (you'll need to be rooted for this to work). On stock recovery, go down to "apply update from adb" and then from your computer type in "adb sideload <filename.zip>". Within a few minutes you should be on Android 4.4.1 and your device should be rebooting. Its just that simple.
Of course if you don't want to do all of that, you can simply wait for the OTA. And remember that clearing Google Services Framework hurts and doesn't help you get the OTA faster. Same with hitting the "Check for updates" button in "About Phone". Or in this case "About tablet".
For those that do attempt to sideload this update, be sure to let us know in the comments below how this works out for you.
