 I've found newer CX-A39 H3 firmware has been released.

 It works fine on opi plus. and more stable.

 You can burn to sdcard or EMMC.
 It works with some ploblem
 
 Work :
 1. ethernet
 2. video playing : up to 4K@30fps (1080P@30fps, 1080P@60fps, 4K@30fps)
 3. It supports DTS, AC3(stock firmware for opi plus doesn't support)
 4. Google Playstore, youtube and other apps works fine.
 5. Not Rooted
 6. 4 usb port
 
 Problem :
 1. wifi doesn't work.
 2. I/O Speed is still slow( I got only 12MB/s. Debian server works over 30MB/s)
 3. no 4K 30Hz output through hdmi(max is 1080P 60Hz)
 4. otg works but low power.
 5. Through OTG port can not be connected to a PC. (It's big problem. I can't use adb and rooting)
 
 It's amazing video play.
 It also played 4K 60fps(with some frame drop), in my PC not be played .
 
 I've tried roothing but failed.
 I can unpack and repack on ubuntu.
 But, I don't know how to mak rooing image.
 I googled all day long, but haven't found.
 
 Is there anybody can tell me how to?
