The latest build (KTU84Q) of Google’s recently updated operating system, 4.4.4 KitKat Release 2, is now officially available to download for Nexus 5’s in Australia (Telstra), New Zealand (2Degrees) and India. However, this update doesn’t use Android’s standard over-the-air (OTA) upgrade process. Instead, you will need to download the 4.4.4 factory images and install them on your device via the search engine giants Developer Platform.
