Libre Elec not booting (black screen) on Intel NUC

Hi.

After updating to latest verison LibreElec won't boot.

I see only black screen

Platform Intel NUC (generic).

---edit---

After several attempts to turn it on and off, Libreelec started up with the default image settings.

It was previously set to 1080p 120Hz.

After a problem with booting up the above values changed to 4k 60Hz. I set everything from scratch. We'll see how it goes.

There have been at least 7 Intel generation NUCs released by now. Some more detail would be nice.

And yes, Kodi is still not a fan of 120Hz screens.

Thank you for your answer.

More details:

Intel NUC7i5BNH

Before the update, everything was working as it should. There were no problems with the120Hz frequency.

---Update---

Unfortunately, the problem still exists

I turned the device off, turned it back on and all I have is a black screen.

The device also does not respond to ping.

If you can log in remotely into your NUC, you can still provide a debug log. Is that possible?

As I wrote above - if there is a black screen when you turn on the device there is no network access either.

However, if after a few - several attempts kodi starts then I can turn on debug. But I guess this is not the point ?

ok, i see the problem.

After connecting NUC to the monitor and many restarts error appears:

*** Error in mount_flash: mount_part: Unknown filesystem ***

### Starting debugging shell for boot step: mount_flash... type exit to quit ###

After reboot LibreElec starts normally.

So, this is the problem.

Once in a dozen times, the system fails to load.

It looks like the black screen is the result of the TV not waking up.

The monitor does wake up and shows the error.

My NUC have two discs - 1TB hdd for data and mSata for boot.

---edit---

I noticed one more thing.

When shutting down for a short moment, an error appears:

Failed to unmount /flash: device or resource busy

systemd-shutdown[1]: Failed to finalize file systems, loop devices, ignoring.
