Default [Q] i9505 still running on 4.3

Hi, my i9505 is still running 4.3 android. I didnt get the update to the 4.4 OTA. Kies only shows message, that the device is running the latest firmware.
When I bought i9505, I rotted the 4.2. Than the android was updated to 4.3 (gets unrooted), I dont remeber, if I get the update OTA/Kies, or if I updated it via odin
How can I get the latest android updates?
Thank you.

[if any other info needed, please ask]

edit: so I updated it to 4.3 via odin with an german FW.
