Venu 3 stuck on 8.28

Hi guys

is it anyway to force update from 8.28 to newest stable (or beta Disappointed ) version? I tried do it via pc and using wifi on my watch. It doesn't matter if I'm opt-in to beta or not. 

I saw that it should be able to do it using GUPDATE.GCD directly on watch memory but i cannot find it for venu 3 Disappointed
