I'll try pastekodi again.
I also get a black screen on a clean flash of 10.0.1 and 10.0.2 (normal builds). Same never happened with 10.0.0 and before. But thanks I'll do a search.
This looks like the same issue:
after the LE 10.0.1 update of my clean installed LE 10.0.0 from the LibreElec menu and a reboot i get no picture anymore. Only the blue screen of my Onkyo AV.
LE 10.0.0 runs fine since 6 Weeks.
Switched to the other HDMI out of the Rpi4.
Completely shutdown and start again the TV, AV Receiver and the RPi4.
Nothing special added in my config.txt.
Tried to add in cmdline.txt:
I can still reach Kodi via SSH and the Android Yatse app. Playing media, controlling CEC via TV…
Unfortunately no real fixes came out of it (yet..).
Not really sure what else to do. It's just too bad really I can't use the newer builds anymore. The problem occurs on both Pi4's here. Both are connected to LG 4k tv's.
