Pixhawk cube orange wont boot up

Thank you Alvin and Ian, but I’ve been trying to do the same thing for the past two days, I tried flashing the Copter, Plane, and even the Rover but still no luck, every time the same error occurs saying “no need to upload already on the board” I think I’m unable to explain the problem correctly, when I connect the Cube with my Laptop the orange light on the cube turns on and won’t go off and this is exactly what happens when I power up cube
Could you perhaps recommend another option for me to consider?
