Can you brick an ECM to the point it cant be fixed?

So there is was... updating my tune to accept an Omni 4 bar map sensor and bricked my ECM. I had completed everything as per the instructions of the walk through (to enable the sensor, Omni4bar #1,2,&3 enabled, rescaled map based load cal #1 ,2&3 so they're the same & change their scaling to Omni 4 bar, then changed the scaling of the fuel compensation MAT vs. MAP so the Omni 4 bar matched the stock map but scaled in Omni 4 bar kPa). Flashed it to the ECM then ECUFlash stopped at 92% during writing. Yes, the car was on a battery tender. Took the ECM out and tried to bench flash it, and get "no response to any know code". I've tried reflashing my last known good ROM and my original ROM and get the same message. I've reconnected my jumper wires 3 times and tried both ROMs each time. I've used a DVOM to check my harness and everything is good. I've performed a bench flash once before and had no problems.

Harness hooks up as followed
"+" 82,92,104 & 16
"-" 72,4 & 5
7 -> 80
6 -> 90
14 -> 90
12 -> 103

 

You are using recovery flash the first time correct?

Recover flash, and then regular flash back to good known before installing in car.

 

Yes, I used the recovery method and all the other standard tricks. After to many hours of reading old treads, one member had the same issue back 2009. After reconnected everything a 4th time and it worked so it seems to be a connection error on my end.

ONBOOST-“Pin 8 or 12 on the obd plug IS NOT connected to pin 103 on the ecu which is the reflash pin. i had this problem on my ecu so i had to send it to Colby (all the way from New Zealand). follow the above instructions from tephra, that should fix your problem.”
