So I wrote to BenF through PM here on forum and I a send message to seller of Chinese DSO clone if they could send me source code for their firmware. If only we could get latest BenF source code and working “new LCD model” firmware source code it hopefully could get married.
New hardware is permanent/persistent issue and it won’t go away until we find a way around it. Help me out here if you can please.
Hello everybody BTW 
[EDIT]
I found a hint on Chinese forum:
Previous LCD driver: 7781
Current LCD driver: 9341
