2012 Buick Lacrosse Ecu programming issue

[ateyourv8]

Hey all!
Im attempting to replace an ecu on a 2012 Buick lacrosse. I have a used one trying to program with SPS.






I select replace and reprogram, it goes through, communicates with car and begins the flash. At 99% i get an error and after that every time i attempt to re start the programming i get E6787 cant reprogram the same calibration. The Vin remains the one from used ecu even though i input the correct one i need.




I have found a few threads with no solution. Any help with this would be greatly appreciated!
Thanks!

Check on acdelcotds website to see if its Global A Architecture.. If it is then it will not work because of environment security and pin code.... Must put New Pcm if indeed its global a


This vehicle is Global A I checked
