If the ground pins are now black and weren't before, then I don't think it looks fine. All I can think of is that since the connector was meant for a different device, the wiring in the connector could have been different. Some wires may have been crossed and incorrect power was sent to the wrong pins possibly shorting out the HQCT. Smoke and burned pins sounds fried to me, but I hope not.
If it is fried, you can look into cheaper and better radio solutions. I still have my HQCT installed but am using a Directed HDRadio. I'm much happier with it over the HQCT.
