Compare the HW revisions of RPi 4B/2GB and RPi 4B/4GB, also check / compare the bootloader versions and bootloader configs. Without any details shared it's hard to say what the root of the issue is.

So it looks like the firmware problem - thanks zehner for the link!

Is just a firmware downgrade usefull possible with rpi-eeprom-update?

I have tested to Installd LibreELEC 10.0.1 with different SD-Cards:

LibreELEC 10.0.1 works on RPI4b 2GB von summer 2019 and works not on my new (from last week) RPI4b 4GB -> Screen stays black

Both without changes for config.txt

If I try LibreELEC 9.x both RPI4b are working without problems (No change @ config.txt, same SD-Cards, same cables,...)

If I write

hdmi_force_hotplug=1

hdmi_drive=2

in the config.txt file the screen displays some text (@HDMI0) but stops soon while booting with

Trying partition: 0

lba: 8192 oem ...

"Bad cluster number 0"

Any idea what's going wrong?
