Alright what the F**K... 03 LB7 tried to read the ECM and it was giving all sorts of weird codes like ECM is locked no data received.... Finally read the ECM and after 5 tries finally flashed the ECM. Went to make an adjustment via a Cal flash and tried 4 or 5 times didn't work tried one last time and it quickly said 100% successful which wasn't right as it never counted down. Now truck won't start but I can clear codes and I can hear the ECM power on/off... Wtf

Bricked it? Anything else running off the data?

Try Full Flashing it? Any security systems on the truck or aftermarket stereo? Ive ran into that problem several times and I've had to pull the ECM out and swap it into another truck to flash it.

I had a similar problem two years ago with a lly and a lb7 about 6 months ago. I was flashing the tune and erased it then stopped counting down. Couldnt do anything with it after that and all the truck would do was turn over and not start as it acted like it had a blank ECM which it did. Pulled it out and swapped it into another truck and she flashed just fine. Only two trucks that I had do that. I tried "try alt keys" and checked all the other boxes too and no luck.
