2019 Silverado 5.3 a10

Im really wanting to talk with someone about some issues were having with a truck we flashed a file into. Very long story but willing to pay someone for their time to help us resolve the issuses. After flashing file pulled from vehicle we now have abs lights, check engine light, etc light, brake light and vehicle will not move in any gear. We also have to disconnect battery to power down vehicle as it thinks its not in park. Any help would be appreciated.

Did you try reflashing with the stock file?

Yes I did. With the camshaft replacement and the dod delete it wasnt happy and went into failsafe mode.

This original file may work as a starting point.

I have a 2019 Silverado LD (old body style) and have attached the original file I pulled before any changes were made. I am not sure what the a10 is but mine is gen 5 with 6l80 automatic, 2WD model and the ECM/PCM didn't need modified.

Wrong PCM. OP's vehicle is E90.
