HP Tuners Pro LOCKED/Killed my ECU/PCM??? "Bricked"

Not sure what happened, but my computer in the 4.8 swap died in the middle of writing a tune! I’ve used HP Tuners for 2yrs same vehicle and no previous issues. Detection Protocol Failed This means for what ever reason the PCM’s in your vehicles computer stop responding. 😳 I couldn’t find much info on this happening!!!
