U7186 did not load tune and will not reload factory tune

Post by sunk99 »

I have a 2007 GMC sierra 2500 HD that I was attempting to load a tune in from a Predator #U7186 and It will not load a tune into my truck and the worst of my problems is that it will not load my factory tune back into the truck and it will not start now.Please help!I cannot get back to the main menu to find the revision #.

I disconnected both batterys and touched the positive and negative of the main battery together, reconnected and nothing changed. I also removed the suggested fuses under the hood and no start again.
