I flashed in the custom os for my 2005 silverado because I'm preparing the truck for boost. Then flashed in the cal file. Truck started and ran so i read the file and saved it so i could change all the values to prepare for boost. I decided to flash the stock tune and stock o/s back in so i could drive the truck later. Right when i started flashing the truck i realized the key wasn't on so i made the dumb mistake of cancelling the flash. EFI live cancelled the flash but now i can't communicate to the ecm. When i hit auto-detect it doesn't detect the ecm. I tried pulling the negative battery cable and pulling ecm fuses. Also tried resetting the computer but i still can no connect to the ecm. From research on here it seems like i bricked the ecm. Thoughts?
