A few of us are in the same boat, with Pi 4s that can’t run LE. There is no solution afaik and it looks like the dev team is too busy with LE 10 to look into it.

Same issue with 9.2.7, tested just now.

Just tried with 9.2.7 and it's the same behaviour.

It's really strange. Do you have a customized bootloater config / did you also changed it when replacing bootloader versions? What's your current?
Are you sure the SD card / USB key imaging was done properly?
Also this is strange:
I am running LE 10 Nightly builds but never had an issue with wired ethernet nor kernel panic when rebooted from menu.
Didn't you try to overclock your RPi?
If not, I am out of ideas and perhaps there could be really a compatibility issue with RPi 4B v1.4 but I am afraid it won't be ever analyzed in LE 9.2.6. Move to LE 10 Nightly builds and you won't be sorry. Despite there are some issues, in general it works fine and the progress is every day.
I tried 9.95.3 and it works better indeed. Ethernet worked, CEC as well (some of it, play/pause/skip doesn't work, and other keys I programmed for subtitles don't either).
The main issue for me is that subtitles don't seem to work on 4K content but work fine on other content. That's a deal breaker for us so I'm stuck with 9.2 stable until 10 is released/fixed.
Any guess about when LE10 will be ready? Are we talking weeks, or 6 months, or 1 year?

I also tried every older bootloader all the way down to 2020-04-16 (2019-09-10 doesn't work in the Pi 4 v1.4, I guess the revision is more recent that the bootloader) and still the same result: it always freezes.

Make sure you are using HDMI0 output (next to the power connector).
Also try with another HDMI device (a PC display with FHD resolution if possible) to test if there's any change.
Done and done, same outcome.

We saw that before, most of the times it was a problem with the SD card (the one or the other way).
Try a SD card writing software that verify that everything is correctly written to SD card - balenaEtcher.
If this is not working try a different SD card. Borderline power supplies can have similar effects.
I sincerely think it is something else:
- I've tried 3 SD cards: they all work fine with Ubuntu, RetroPie, Pi OS, LE 10, but not 9.2.6 on the same RPi4
- I've tried 2 USB keys to boot from: they all work fine with Ubuntu, RetroPie, Pi OS, LE 10, but not 9.2.6 on the same RPi4
- I'm using the official 15W PSU but I've also tried with an Apple Macbook Pro USB-C PSU, still freezes at boot
The fact that it hangs with the official PSU and with an Apple MBP PSU (which is rated for about 90W I think?), with three different SD cards, two different USB keys, but only when running LE 9.2.6 but not other OSes makes me very strongly suspect something is wrong with LE 9.2.6 rather than the Pi or SD or PSU.

I'm assuming you are just putting a blank card in to your PC, using Balena to install Libre and then putting that card into your PI, no other weird and wonderful things in between.
If thats the case you could have a faulty Pi, which is causing the issue,
I'm not sure the Pi is faulty because there are others with the issue on the forum, and the same Pi, AC adapter, TV, SD card, etc but with Pi OS or Ubuntu or RetroPie or even LE 10 work just fine.

As a last ditch effort, I tried the 9.2.6 image with LE10's boot partition. It sorta boots but drops me into an emergency shell. I can't really see what's going on because it uses 4096x2160 and my TV is 3840x2160 so most of the output is truncated and invisible.
Anyway, that doesn't make 9.2.6 functional either so I'm back to where I started.

Id be trying a different Pi4 as i've been through various versions of Libreelec on mine with no issue. If the same card works on other Pi models it does take the focus away from the card, OS, media centre and points towards hardware. have you got someone local with a PI4 that you can put their working card in your PI to see if it works?
Unfortunately not. But the same cards work in that Pi with other images/OSes, so it would show everything is working but LE 9.2.6 on my RPi 4.
-
have you tried the newly created cards on an older PI to see if they work, if they do it would suggest its a PI issue rather than software.
These cards in three other Pi (model 1 and 3): works
These cards with Pi OS/LE10beta in that Rpi 4: works
These cards with LE in that Rpi 4: hangs
A USB dongle with Pi OS/LE10beta in that Rpi 4: works
Same USB dongle with LE in that Rpi 4: hangs
The Pi is fine but only with certain images. LE 9.2 isn't one of them.

Same problem here, brand new 9.2.6 image on a Pi 4 2GB with bootloader v2021-04-29 and it just won't boot. Hangs at a black screen with a frozen cursor on the top left corner. Pi OS works, RetroPie works. LE10 beta works but is unusable for me (no wired ethernet connection, CEC stops working randomly, it's in the family room, I need it to just work so beta software is not a good fit there)
-
Still no luck. I tried everything I could think of: all 9.1 and 9.2 images, 9.2.6 but with the boot partition files from Pi OS (as this one boots normally), different SD cards (brands and sizes)... It just won't work.
-
This is what happened on my latest try with explicitly setting `hdmi_group` and `hdmi_mode` in the config.txt
-
I tried the 10 beta, and it could boot properly. But it's too unstable (I'm getting no wired ethernet, CEC doesn't work reliably, reboot via menu gives a kernel panic...) so it's not a solution I can live with.
-
Maybe check 10 beta?
Or archive.libreelec.tv Index of /
News page tells that they had to release 9.2.5 as bugfix for RPi4. So older versions are likely not to work.
Thanks. I'd like to avoid running the beta version... This is in the family room and we just want it to work with no fuss.

I have upgraded to a Pi 4 today, so I backed up my settings and burned a fresh 9.2.6 Pi 4 SD card. I tried with Balena Etcher and LE's USB tool.
When I boot, I see the rainbow, then it hangs with a black screen and a `_` in the top left corner. Nothing happens then, and the device isn't visible on the network.
I tried `https://releases.libreelec.tv/LibreELEC-RPi4.arm-9.2.{0-5}.img.gz` to get an older image as 9.2.6 seems problematic (it hung often on the Pi 3 as well), but the file doesn't exist.
Where can I get an older Pi 4 image for LE 9.2 that isn't 9.2.6?Tried every 9.1 and 9.2 release, and I either get a message from the EEPROM that I need to update the software (even though I'm running the latest EEPROM, 2021-04-29) or it just does more of the same: black screen with frozen cursor. -
Also worth pointing out that 4K HDR is 90% functional already; 4K@60 still needs work (but there is not much media in that refresh rate) and 10-bit/12-bit are still WIP, but 8-bit output is more than watchable.
Good to know, and thanks for all the hard work!
