Cardano on the rocks does not follow documented steps

I am trying to setup my Cardano on the rocks device. Everything is in place, the rockpi without internet connection flashes red. When I insert a cable for Internet connection (that is working - tested on laptop), the led does not blink blue/green, nothing. Display doesn’t show anything.
Can you please help me with this?

I connected HDMI and i get "rockpi login: ". Did I not flash correctly?

see there, it is already discussed.
In basic image there is loosing script for setup the led. Script has to be transfer to the Rockpi and manually started.
But after that follows next problem, LCD-124x64also did not work and is not solved yet.
