+1. This was the one that I was worried most about - the service guy hooking up the car to their system and accidentally performing the update which later could not be undone!
I had asked the same doubt to the service manager and he told that this is something that cannot be accidentally done and if it is clearly indicated in the job card not to perform the update, the service guy will not do this.
