Good news everyone!
New images for H3 boards with onboard Realtek WIFI driver (RTL8189FTV) with 5.3 kernel fixes are ready. If someone need WIFI like me here are images for H3 boards.
Images tested only for Orange Pi plus 2E. I had one problem after installation. I wouldn't be able to see wireless networks in setup wizzard, but it was listed in LibreELEC connections menu.

Thanks jernej for your support. I have no time to start new thread with new independent build. I believe you won't mind me publishing it here
