Ok, I may be talking out of my **** on this, as I haven’t researched Techstream (will at some point), but do you have or need an external power supply hooked up to the car while doing this?
On my other car, the dealer tool I have requires the voltage, read at the battery, to be at or above 12.5 volts in order for module programming to be initiated, and if it dips below while updating a module, you risk bricking the car. For my model year, at least a 13.4 volt 25 amp supply must be connect, newer models require a 50 amp supply.

Still haven't gotten this fixed, dealership is saying a new module that isn't already paired to the car needs the other ECU to be replaced for them to match. They want $4500 to fix this ****
