Only when I got a dead touch I figured out that it has a different chip: FT5336GQQ (see photo included).
So, now I'm able to use it only with the mouse connected via OTG-cable. Tried to use some other bin files, but no success. Touch screen is fully inactive.
I guess if I find the right bin file - I could solve that - or am I wrong?
Any ideas, guys, how to solve that problem? Please, HELP.
