OK, I can certainly understand your frustration. This looks almost like a case of "Catch 22". (Your truck won't start unless you're at Level 0, but to get to a functioning Level 0, you have to have an operational truck.)
I honestly think the PCM CAN be recovered though. Sorry you're going though so much heartache. Most of us never have a single problem.
Possibly, you ARE at stock, but now the PATS is activated and they'll have to override that. I know Bill Cohron at PHP CAN write a file that will override the PATS system, but I don't know about restoring it. (And, I'd certainly want it active.)
I've got no solutions, and it's too late anyway. Don't give up on Edge. I think they WILL do all in their power to make this right for you.
Keep us in the loop.
