When Google announced KitKat, they confirmed that the Samsung Galaxy Nexus had officially reached the end of its support life and that it would not see the update from 4.3 to 4.4. Of course, the entire reason many people buy these Nexus devices is so they don’t have to settle for “official” updates and can take care of it themselves, and the Galaxy Nexus is no different. Thanks to developer PlayfulGod on XDA, the Gnex finally has a fully functional KitKat ROM available so it can join the Nexus 4 and Nexus 5 with up-to-date software.
The ROM is built off of Cyanogenmod 11 source, and every major thing works, including data, phone calls, camera, etc. There are a handful of bugs left to iron out, including panorama being broken and a graphical glitch when taking screenshots (although the screenshots turn out fine) but neither of those things are going to affect the ROM in a major way.
If you’re interested, you can find the ROM below. Remember, unlocking your device and flashing custom software can void your warranty, so flash at your own risk.
