So my car was involved in an accident, and I'm fairly certain insurance is going to total it out. I tried flashing the ECU back to stock, but everytime I try to unlock the flashpro, it tells me I need to upload a stock calibration first. Is there anyone who has experienced this problem before and what did you do? Thanks

*UPDATE*

I was able to get the car to finally unlock. My problem was I was uploading the stock tune vs selecting the "return the car to stock" tab. Problem fixed. Thanks to anyone who looked.
