I am very new to this, but very pleased I am involved!
With a lot of help from wrxtasy at the Kodi forum I have a working LibreElec Kodi 17.3 box. It is an (ex)Android box: X96 Amlogic S905X Chip, Android 6.0 Marshmallow, Quad Core ARM cortex-A53 2.0GHZ Processor.
At present everything is running well from a 1Gb microSD card but I am wasting the internal memory (1+8Gb) of the device. Can someone please point me in the direction of instructions to move or copy my installation to the internal space and eradicate Android forever?
I have seen references on this forum to: "installtointernal" but I have no idea how to find or use it.
