Help with ISP mode flash

Hello, I am trying to regain access to target MCU. I've read this: 


Regaining debug access to target MCU &  ISP Reset over debug.


I know that the 1549 is in ISP mode because I'm monitoring the signal activity on the pins and everything goes quiet after pressing and releasing Reset while holding ISP0 & 1. So I get that far. But while entering a debug or flash session I still don't get anywhere.

Debug error: 

Flash Error:

Any help with regaining access would be appreciated. There's 3 boards that are locked up from this same error and I've really been spinning my wheels on this for some time now.
