Can't see autostart.sh via samba and still not sure how to create it, sorry for being thick. I thought the latest build used interactive according to the changelog: LibreELECI might just revert to 7.0.1.3 and see if it's any better as I don't think you changed much in 7.0.1.4.
You won't see autostart.sh unless you have created it.
It's simply a text file list of commands, like most script files and needs to be created in / moved to /storage/.config via SSH
or alternatively the configfiles samba share.
