How To Upload Custom Themes on WD TV Live SMP

I recently purchased  both a  WD TV Live SMP and a WD TV Live Hub.  I have no trouble uploading my own custom theme into the Hub but how do I get it into a SMP?

SMP does not allow the custom firmware and there are not many made themes for the smp yet unfortunatly. I too have the SMP and thought i could customise it like the hub and earlier versions but you can not =(

Only themes avaliable for the smp as far as im aware at the moment are the ones found in “Apperance” on the smp and the mojo (SMP) theme and soon the darktheme.
