@feerlessleadr I have this exact same issue, EVO+ card, MINIX U9-H, it shows LE splash screen and then goes black and nothing else shows up. I'm using the file that wrxtasy posted.
How were you able to install to the device? I can see the assigned IP address in my router as LibreELEC but it won't let me SSH into it, keeps refusing the connection.
ETA the LE computer shows up in Windows Explorer and I can now navigate the directories but I still can't SSH into it, screen is still black.
Adding more info I just tried another display, time time a 1080P instead of my 4K and it does the exact same thing, LE splash screen then it goes black. Once the screen goes black the only way to reboot or turn off the U9 is to unplug it.
I just tried a USB drive and the exact same thing happened.
I tried just booting into the stock OS and it appears my remote is DOA as I can't navigate at all
So a couple things, I was getting the black screen using wrxtasy's dtb on both my EVO+ & usb drive, so I decided to try the default dtb in the OP 1 more time on both. This time on the EVO, I got the couldn't mount Libreelec Disk error on the splash screen. However, using the OPE dtb and my sandisk usb drive, it booted right into LE. Keep in mind, I had tried a few other USB drives before (I had a few kingston laying around that I had used for LE in the past) and I always either got the black screen with wrxtasy's dtb, or the diskmount error using the OP dtb.
This was the first time I had tried this thumb drive and it worked straight away, so the U9 must not have liked something with my other thumb drives and the EVO to not be able to mount the LE disk.
I have since installed LE to the internal memory however, since running LE from the thumb drive had a 'crazy long startup time' according to my wife.
The model usb stick that ended up working was a sandisk SDWS4. I hope this helps somewhat.
