Sony rolled Android 4.4.2 KitKat on Xperia Z1, Z Ultra and Z1 Compact a month back and made promise that soon it will roll for Xperia Z, ZL, ZR and Tablet Z in mid May 2014 hopefully. For all Xperia Z users who are waiting for official Sony KitKat update, leaked Xperia Z KitKat 4.4.2 10.5.A.0.227 firmware ROM is now available to install on Xperia Z unlocked bootloader handsets only, courtesy of legendary XDA developer DooMLoRD.

There is no specific info that 10.5.A.0.227 firmware will hit as official update for Xperia Z but now you can test in on your Xperia Z if you don’t want to wait anymore.
