For the RPi devices you can download the appropriate LibreELEC*.img.gz file, transfer the file to the /storage/.update/ folder, and then reboot the RPi. On bootup the RPi will extract and install the image.

Okay. I've done that for updates, e.g. 8.x to 8.x.x, and the update was in a tarball. I didn't know that would work for an image file.
