finally... it worked. I did not find the elements app but was able to switch "LED" in factory settings to another color ("R"). This was showing "RGB" wich actually means white color.It doesn't matter. Change from RGB to red or blue, then reboot and see if you have a new settings menu option. If not go back to factory settings and change back to RGB and reboot. Keep trying.
Shame on me, why this took such a lot of effort. THX for your assistance!
