I have a 2017 FK8 and it now won't start after update.
I updated my program and then my Flashpro. I wanted to put my fk8 back to factory but now its stuck in Recovery mode. I read that I have to unplug EVERYTHING and then plug it back up to try again.
I also deleted my old tune from the Pro as well.
After reinstalling my old tune and retrying back to stock, it still won't turn over. It'll show "Recovery Mod" and then switch to green but it still won't start.
Any help on want to do would be appreciative.
Won't start after FlashPro update.

Re: Won't start after FlashPro update.
Most likely your battery is discharged (less than 11.5-11.6v) and the reflash cannot be completed. Connect a charger to the battery, but it is very important not to disconnect the battery even for a moment.
After charging the battery a little, you can try to reflash again.

I tried that a few times now and still the same issue. Battery is currently 12.54.
I'm currently trying to just put it back to Stock and it still won't start. When I push the START button after the time is completed, I'll push it, it beeps at me, Ill push it 2 more times and then the ignition finally turns off.

With everything plugged in and the ignition in the on position, go to the Help menu and click on “send feedback”. Include a detailed description of the issue.

Update. The FlashPro cuase an internal voltage code that wouldn't allow the car to start. Had to get a reader to clear it.

For the sake of completeness (and for anyone searching due to a similar issue in the future), can you share what was the DTC and what type of tool was required to clear it?
