How do I fix the brick condition of my CW-Hysky?

During an experiment to port the internals of CW-Hysky’s FPGA, it became bricked and is not recognized by the PC even through the USB port. Is there a way to fix this? All LED lights come on except status.

Try shorting the erase pin (or using the button if there is one) as noted here, then re-program the firmware.

If this fails it would be useful to know the error messages that you get.
