(S912) H96 Pro+ Black Board - Trouble Remote Power ON

Hello
i had installed CoreELEC-S912.arm-8.95.3.img on my H96 Pro+ with a Black Mainboard.
Rename gxm_q200_3g.dtb to dtb.img

Remote Keys works according this guide:

But, i cant Power On my Machine via Remote. Only control Kodi works.

H96 Pro+:
