Update 20170225.
Checked on MIIIPlus - wired network is working, WiFi - working both range, BT works. In the settings there is items for the sound in 5.1 and SPDIF, but I have no such equipment, so can't check.
As part of your image there is a file "boot.scr" to activate the multi-boot on the Minix models.

Attention. In the latter case the image LE in the shutdown menu has several additional items. Mode reboot into Recovery - restart the TV box to factory system Recovery. Reboot with the install LE in the internal memory, restarts the system and executes the copy (install) the LE in the internal memory (without needing to use SSH). In this setup, the internal memory will be copied all the settings that are made when you run the system from that external media. Pay attention to the installation procedure in the internal memory test and possible unforeseen outcomes. Therefore, we strongly suggest to use this function only if You will have confirmation of the correct operation of this function on Your TV box, You just know that I will be able to restore the TV box when not full-time results.
