    Upgraded to 3bar OS, flashed base map in, now ECU not readable or writeable.

    Any ideas why? It says Authorization failure/exceeded tries/security access denied. It's also saying OS IDs don't match. Everything was working just fine until I upgraded to the 3bar OS. I was able to flash it into the car and start the car and as I attempted to make my first change, I was locked out of everything. Any ideas? Car is a 2000 WS6. Says File OS(12202088) does not match VC OS ID(1231003) Tried locking and unlocking file as well. Any ideas?

    Post the file itself. Did you make a 3 bar file from the existing stock OS in the car?

    Yes it was a stock OS that was already registered to this cable. I was able to upgrade the OS and flash it once and then it locked me out after. I have to get the file as it was not done on my cable.
