Has my immobilizer been damaged/reset?

Question

I have an EVO-ALL and EVO-NIST1 T-harness. I integrated the harness into my car with all necessary t-connections and soldered connections in place. When I attempted to follow the programming procedure, at step 7, I was only getting a solid blue LED. I re-attempted the procedure, same result. I started the car afterwards (with EVO-ALL disconnected), and my security light is now on solid red, indicating an immobilizer malfunction. I have tried leaving the battery disconnected (for at least 15 minutes), I left the car sit overnight (battery connected, another user here had a similar issue and it resolved itself overnight), and the light is still on when the car is started. If I pull the battery from either of my keys and attempt to start it by holding it near the start button, the car will give a "NO KEY" message.

What went wrong and how can I fix it? Currently I'm concerned that the device caused permanent damage to my car.

Have only the red connector connected when doing that test. 

If the vehicle still does not start, put back the factory harness and try again.

Very common on Nissan, after driving a couple miles it will  shut off.
