Kekilo m9x m3 firmware needed - Bricked box

Hello everyone. since yesterday I am trying to recover my android TV Box, but due to the name is little known, it's hard for me to find a working firmware. I've tried many other software, but it did not work in every case. One did not have WIFI, the second hung after a dozen or so minutes of work and required a restart, in the third there was not a mouse and USB ports, and the rest did not even want to boot.

My hardware configuration is:

CPU: S912
WIFI: Q6330
2 Gb Ram DDR3 - pe039-125 tp
16 Gb Rom
Motherboard: cz-s31-v2.1
