Need Bios to reflash an unresponsive Hi10 Pro

Hello, i read in several Forums that i can ask here to get the correct bios for this dualboot hi10 pro. I made all tests i can imagine. I can feel the heat from the cpu as i power it on, but i cant get any image.

So there is no existing Bios that i can reflash with my programmer?
