the LG unit runs a Marvell 88F6192 800 MHz processor, I don't think that will support Vortexbox.
Vortexbox requirements state "Any 500MHz P4 or faster i686 class processor should work well".
You need an actual PC to install VB, even an old one.
Wish I knew Ed, I installed it on an old IBM Aptiva, but gave it away in Nov.
