GTKing Pro bricked, USB Burning Tool not working

applemS

Hello,

please help me to unbrick my GT King Pro box.
I tried to flash an update of SlimboxTV using USB Burning tool but the flashing always stops at "Download System" between 12 and 30%.
The box doesn't have any signal on HDMI anymore.

I tried like 20x to flash the firmware using different versions of USB download tool, all without luck.
Can you please let me know how to unbrick the box? Attached a photo of the board.

Thank you!
