Original nrf51DK board have default com port. But after I use MCP windows,

it'll need flashing a image and short P0.30 GND, com port disappear.

Even after reflashing Jlink if bin file.

How to let it back?

your device seems operational, because the recover process did not complain. Which means that your device has no problem. I am not sure why it is not showing as com port.
