With LE/Kodi, I can only go as far as 'green light' but it would be nice to be able to have the full shutdown option.
Shutdown menu is under shutdown button. There is only "power off" available as this is what Amlogic kernel provides. It makes the device go into low power u-boot shutdown (<0.1 W power draw, CPU is completely off). Anything more than this is vendor-specific implementation that I have no sources for.
Please don't cross-post next time.
