I checked the UUID and the vfat-partition shown after blkid is indeed wrong (3E92-8632).

So I will have to edit the syslinux.cfg. Sadly I couldn't figure out how to do that. Is it possible to do it within the debugging-shell?

Thank you very much for your help!

Yes, but it's probably easier to boot into LibreELEC and edit it there as you have more tools available.

Assuming /dev/sda is your boot disk (check the output of blkid) then in the debug shell execute:

text:


mount /dev/sda1 /flash

exit

and your system should now proceed to boot into LibreELEC.

If your Storage partition also fails to mount, again because of a changed UUID, then use:

text:


mount /dev/sda2 /storage

exit

Once LibreELEC has booted, login with ssh (username: root, default password: libreelec) and run the following:

text:


mount -o remount,rw /flash

nano /flash/syslinux.cfg

Make the change(s) to fix the UUID, then enter ctrl-x (followed by Y and ENTER) to save the file.

Reboot, and you should hopefully boot straight into LibreELEC.         

First I want to thank you very much for your help! Sadly I wasn't able to boot into LibreELEC, because the storage partition wasn't to be found. I ended up doing a fresh installation what worked fine so far.

The only problem I have now is, that in my audio-configuration I can't choose my output device. There is only one entry (greyed out) with Bluetooth Audio (PULSEAUDIO). I uploaded the logfile to: http://ix.io/1mmf

There are lot INFOs like:

Does this make sense to anyone?
