As always, Google has released factory images for their latest Android 4.4.2 update. They’re available for the Nexus 4 and 5, as well as both versions of the Nexus 7 and the Nexus 10. These images are basically simple ways to flash your device back to completely stock Android, so this doesn’t mean they’re being pushed out OTA yet.
4.4.2 brought a handful of fixes, most notably a patch for an SMS vulernability and some voicemail delivery and notification improvements. If you need any of the factory images, you can find them at the source link below.
