My Xperia Z 6603 still using 4.1.2.
Wandering why there still no update for that?
Already check firmware everytime, but find nothing.
I'm live in indonesia btw.
The update is rolling.Try with sony update service too.
the release is difirent if your phone is under a carrier subscription then you gota wait for carrier to release the 4.3 update to your xperia z.
