The wait is finally over guys! After wasting three darned months to do something this simple (Verizon?), Google has ultimately managed to out the Android 4.4.4 KitKat OS update for the 4G-LTE variant of Nexus 7 tablet (codename “razorg”). Disappointingly enough, this update still isn’t over OTA and has to be downloaded and installed as a factory image that has been downloaded manually.
Manually updating your Nexus device to the new Android 4.4.4 KitKat (KTU84P) update is extremely simple. Once you’ve download the right factory image file for your device, you can easily apply that update using a simple procedure given below. Currently, Android 4.4.4 OTA update is available only for Nexus 4, Nexus 7 2012 Wifi & cellular, Nexus 7 2013 (Wifi) and Nexus 10 devices.
