Need help with Pibus and RPi3B+

[TooEasyL2P]

Installed v19 image, tried to install beta addon from zip and it failed. Updated OSMC and tried again. Again failed to install.
Tried to use v19 with addon that came with it. No sound, screen buttons doesn't work even if I set up them to go to home, fulscreen and so on.

Didn't forgot to change serial device to custom and board to pibus.
Installed bluetooth support from osmc forum.

Edit: I have empty button 6 hold. And if I hold it says that there's no action. So it sees button, but on press there "home" and it doesn't work.
