Followed instructions, registered it and did the updates.
Go out to my 2007 Avalanche. Tool continuously kept freezing. It made a copy of my ECM and TCM. Tried to write tune but failed halfway through. Tool is in recovery mode. Tried to reload Factory stock tune failed numerous times. Truck will not start. Lots of lights on the dash. Take it back to the computer reload updates. Tool finally writes the stock tune in the truck now Starts
, scared to use it again please help
While in recovery mode the tool would often state that my vehicle is not compatible or something along those lines
I have attached the stock tune info and the last right. But these files are no longer on the tool
