Is there anything we can do to help make it work out. Get in touch with Berryboot Owner to update or add support for something?

No. Just don't use Berryboot, it's faulty by design, which is why you are having problems. The Berryboot owner has been contacted in the past and asked to stop distributing LibreELEC releases, which I believe he has agreed to, but someone else is continuing to release bastardised versions of LibreELEC, including my releases.

The version of LibreELEC you are using with Berryboot is not the same version I released, so it's impossible to support, and this goes for official LibreELEC releases too.

If you use Berryboot, the Berryboot developers are your first (and likely only) point of contact for any and all issues.

If you want to multiboot, then use NOOBS or PINN, as these do not butcher the LibreELEC distribution in order to work (they're also officially supported by LibreELEC).

Or maybe new kernel in berryboot could fix this? As 4.14.x is old and LE is using 4.19.x?

There's only one kernel that works with my releases, and that's the kernel I ship with each release.

If you want to randomly replace the kernel I ship with another, as Berryboot does, then ask the Berryboot developers for help as I'm not going to entertain this madness!
