They brought the truck back in and had to flash it 3 more times (About half an hour) before the changes were saved. Sometimes the nature of flashing these types of computers can be problematic.
They should never have returned it to you in that condition. It would have taken all of one minute for the tech to turn it on and verify everything was working before they gave it back to you. It certainly didn't save them any time by giving it to you and having to take it back again.
