I had LibreELEC 9.2.1 on Raspberry Pi 3 without any hardware or software modifications.
I make update to 9.2.3 (copy .img.gz to Update folder and reboot).
I have BLACK SCREEN on boot now.
How can I downgrade to 9.2.1?
9.2.3 is not working on RP 3.
P.S. I downloaded LibreELEC-RPi2.arm-9.0.2.img.gz.
Then upgrade to 9.2.1 and RP is working well.
