Requesting assistance. I was flashing the ecm to dial in the speedometer and the new tank capacity and ran into some problems. I get the error message that the "calibration is missing" and "flash can is not able to determine the license status of this ecm". Attached is the calibration details and a screenshot during a recent flash.

How could the OS and calibration change during a flash. I have no idea what vehicle supports OS 25803708 or Calibration 25818885.
No disconnects were noticed, perhaps a surge in vehicle battery? Anyways, I am skeptical in operating the truck under these conditions. Even a full flash has not resolved the issue. Look forward to your evaluation of the situation.
I have used the following trouble shooting to this point:
Disconnected the batteries for 15 minutes and tried flash again.
EFLive unit lights up when plugged into the OBD-2 connector only (no laptop)
No Blown Fuses
Currently using EFILive V7.5.6 Build 117
Flashscan V2 Firmware 2.06.35
Flashscan V2 Boot Block 2.06.03
Thanks
