Google has posted the factory images for Android 4.4.4 Release 2 — but only for a few specific carriers in a few select countries. And only for the Nexus 5. The release, which carries a build number of KTU84Q, is available for download from Google's Android factory images page, is only good for the Nexus 5 on Telstra in Australia, 2Degrees in New Zealand, and unlocked in India.
