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. Kindly note below mentioned 10.5.A.0.227 firmware ROM is specifically for unlocked bootloader Xperia Z C6603 / C6602 handsets, don’t cross flash it on Xperia ZL, ZR or Tablet Z ( doing so will hard brick your device ).

[ UPDATE – 30 April Is Xperia Z KitKat 10.5.A.0.230 firmware rolling now ?

All features seen on Xperia Z leaked KitKat ROM are almost similar to what we saw on Xperia Z1 KitKat update. Below you can see the about phone detail. Firmware is still very laggy, so if you want to test it, do it at your own risk.

    So far it runs ok but it doesn’t carry an embedded PlayMemories Online in the Album app probably because it’s a internal release.
