Purchased 4 credits, read stock tune and saved it, made one modification, started flashing it and it said 'turn key off then back on and press okay' after that it said 'failed verificafion' and now car won't start, will not let me reflash back to stock tune it says 'unliscensed vehicle' vcm scanner works fine and i can scan the dtc's, throwibg a dtc for lost connection with pcm/tcm, and the car is showing a tool icon, any suggestions?
