Sammix R95s - Do not turn on - Red light only

Gentlemen good afternoon, I need your help to solve my problem with my Sammix R95s 2GB / 16GB, after i doing a firmware installation via USB_Burning_Tool_v2.1.2, after this no longer turned on, I can see that the red light from the back Optical port lights without problems, but the light on the front blue light does not turn on as before, also, the PC does not recognize it as before when connecting via USB.

Mi SAmmix R95s has 2GB Ram and 16GB Rom and a S905x CPU.

Thanks for our help.
