The newest version has a problem flashing the cobalt ss 2.4
Only way to flash is to do a write entire.
But the fun starts after.......then you cant flash a cobalt SS/SC it doesnt let you connect....BUT things get worst then after your car doesnt start.
Solution I had to re-install the whole software from scratch and I was able to re-flash my SS/SC so the car would start or else It would of cost me a nice BIG towing bill from Montreal to Ottawa.
Not very impressed.
