I tried this on my Nexbox A95X S905(not S905X) and it works. Really awesome! Thank you.
At first the power button didn't work. I had to use the study function to copy MXQ PRO's power button.
I used this easy to follow guide to flash the firmware(I forgot how to do it)
I didn't have a male-to-male usb cable so i used the KCX-017. It has a micro usb port so i used a phone cable to flash the nexbox.
"-The led behaviour is the oposite, when the box is turned off the blue led light is on."
This is also true for me, but i don't mind. It turns on and off with the remote and that's what i was looking for.
