Every country has different link. I went to Sony Finland https://www.sony.fi/electronics/support/televisions-projectors-lcd-tvs-android- and there in the search field it put KD-65XF9005 and voila. Latest version. I think if you change .fi in the link abowe to your countrys, you'll get there. Edit: Works. I tried Sony Sweden and put .se instead .fi Just remember to put your exact model in the search field. Mine is a 65" and I don't know if every size of tv has a different file or not. So caveat emptor.

Here is the Swedish link for 65" https://www.sony.se/electronics/support/televisions-projectors-lcd-tvs-android-/kd-65xf9005/downloads

And German version. https://www.sony.de/electronics/support/televisions-projectors-lcd-tvs-android-/kd-65xf9005/downloads
