No. You don't put the files from the tar file. You copy the the tar file itself.
But if you put a recent version then you have a working autoupdate so you don't have to bother copying files at all.
AAh, that is even MORE awesome. Indeed i saw the "autoupdate" with LibreELEC settings and i was wondering what was going on, but you confirmed it then that no worries anymore. Just sit down and enjoy :). Thanks guys for the info.
