Ok I ran threw this before with sct. I have there master back up file saved. Trying to return to stock after upload failed. I tell it to return to stock. It says turn key on, I do and tuner dosent advance. Try select, nothing. Am I missing something. When svt helped me with the last lock up, he gave me the stock file for my car, and it was saved in the tuner but will not load to stock. But it is the same one I used last time to return to stock and it worked fine. Wtf? Please help
