If you’re an owner of a Nexus 4, 7, or 10, and are impatient, the good news is that Google has released the official factory images for those devices. Do bear in mind that the downside of flashing these factory images, instead of waiting for an over-the-air (OTA) update from Google, is that your device will be erased.
This is also a sad reminder that the older Galaxy Nexus won’t be part of this party. Not officially anyways.
The one device that won’t be joining the KitKat party is the Galaxy Nexus. The official excuse is that the Galaxy Nexus is over 18 months old, but the real reason is that Texas Instruments, the company that made the SoC in the Galaxy Nexus, quit the smartphone business about a year ago. Official support for the chip has dried up, so there won’t be a KitKat port for anything with a TI OMAP processor. A lack of official support has never stopped the modding community before, though, so if you have a Galaxy Nexus and really want KitKat, some Googling should be able to turn something up.
