Yes RPi 4B itself consumes over 1A so with 850mA adapter you can probably see a lightning bolt flashing in top right screen's corner which means undervoltage. A more powerful adapter is necessary for sure.

I would say 2 GB SD card is not enough, use at least 4 GB SD card or USB flash.
-
Just for instance - this is a netboot tutorial for RPi 3B / 4B: Network boot your Raspberry Pi - Raspberry Pi Documentation
It's up to everyone to decide if it's convenient for him or not ... I prefer booting from an USB flash / hdd.

The "getedid" script works exactly like the one on x86,
Ìt's not exactly the same, at least "gpu" parameter is missing at RPi 4 and "help" does not work.`
LE:~ # getedid
/usr/bin/getedid create|delete|help
LE:~ # getedid help
/usr/bin/getedid create|delete|help

I am running latest LE 10 Nightly build on RPi 4B / 2GB and have a strange issue with Live TV as Kodi does not show subtitles on some TV channels.
The issue is related to Tvheadend Server 4.3 (Alpha) but subtitles are working in VLC on the same channel when connected to the same TVH 4.3.
When I switch to Tvheadend Server 4.2 (by disabling the TVH 4.3 Add-on and enabling the TVH 4.2 Add-on) without any other change, subtitles are working in Kodi again.
The Tvheadend HTSP Client Add-on version is 8.3.0.1
Could it be a Tvheadend HTSP Client's bug or a Kodi's bug? What can I do to fix that?
BTW. in past, subtitles were also provided as TELETEXT hidden page but it's already discontinued and DVBSUB is now in use at all channels.
The Service details attached.

In LibreElec 9.2.6 it was done like this: settings-> System-> Audio -> Audio output device, and then you had to select -> Pi: HDMI and analogue. LibreElec-RPi4.arm-9.95.1 doesn't have that, which is a pity
Yeah this combination is not possible anymore as the audio drivers has changed.

The bootloader config is stored in EEPROM on RPi 4B so it's still the same regardless of OS (if the OS does not modify it).
I don't see anything strange, it looks like a default but you may play with some options (especially BOOT_ORDER) to see the difference.
See this page for details: Raspberry Pi 4 bootloader configuration - Raspberry Pi Documentation
Also make sure you are using the proper image file ( LibreELEC-RPi4.arm-9.2.6.img.gz ).
You may also try some multiboot (aka NOOBS) image.
BTW. 2GB USB stick is too small AFAIK... Use at least 4 GB.

you should remove all tvheadend server first
This shouldn't be necessary, AFAIK it should be enough to disable Tvheadend Server 4.2 Add-on and install and enable Tvheadend Server 4.3 Add-on instead.
At least on my RPi 4B this works and it's possible to switch between Tvheadend servers 4.3 / 4.2 "online".

You are welcome, so please EDIT this thread's header and Mark it as Resolved.

Once again - Check / share here the bootloader config (output of vcgencmd bootloader_config )...
-
Check Kodi Settings - Interface - Regional - Timezone country

Just discovered, that first time (after upgrade to LibreELEC-RPi4.arm-10.0-nightly-20210415-23234b9.tar ) the long EPG header is rotating in Kodi - TV / Channels view.
That's a great improvement as earlier it was just cut so a part of EPG text was missing.
The bad is that it works just for a short time, then stops working and Kodi restart is necessary to have it working again.
Also in TV Guide (Kodi- TV / Timeline) there's still just a part of long EPG headers.

Don't you have any bootable device connected to USB port?
Read this: Boot hang after "random: crng init done" - Raspberry Pi Forums
I would try to disconnect anything from your RPi except display and try to boot.
Check / share the bootloader config - maybe there's a boot preference incompatible with older firmware (which is in older LE image). If this is the case, perhaps it could be possible to replace the RPi firmware in your older LE with the working firmware from the working LE image.
Also try to compare the cmdline.txt files from working / not working images if there's any difference.

Just FYI - some TVs does ignore the CEC power off command. It may also depend on TV settings.
In fact, there's nothing like a CEC standard existing among devices, even on basic functions. I have tested it with several HDMI devices and stopped using CEC as it was a one big pain.
-
Which bootloader version do you have installed? Check / upgrade it to latest from working OS as described here.
-
So don't hesitate to EDIT THREAD and Mark as Resolved...
-
You may also try the Raspberry Pi Imager ( Raspberry Pi OS – Raspberry Pi ).
If it's the same issue and you don't have the latest bootloader version installed, you may experience some SD card incompatibilities.
Then I would try to image Raspberry PI OS to the same SD card and test if it works. If not, try to use USB flash key instead of SD card, this should be more reliable.
In case RPi OS works, check the bootloader version and if it's obsolete, upgrade to latest as described for instance here.
Then try to image LE 9.2.6 again (I would not go back anyway...).

This is not a file but a socket. Read this post again and more carefully until you understand, I can't explain it better. Also keep in mind the post is 4 years old so some things may be different in LE 10.
As described, the original irserver daemon uses the same LIRC socket (/run/lirc/lircd) , the custom irserver daemon from old LibreELEC & OpenELEC uses a different socket (/run/lirc/lircd.irtrans). The difference is explained, I don't know if Kodi can work with original irserver daemon without any changes as apa was using the custom one and therefore described the changes necessary for alternate socket.
You need to test yourself.
