Narrative:
During the takeoff roll an EICAS message appeared. I pointed to the message and announced 'door'. The captain looked at the message and proceeded to reject the takeoff. I notified the tower that we were rejecting the takeoff. The captain then said that he was going to let the airplane roll to the end and that he was not going to use reverse. I told the tower that we were planning to turn left at the end. The tower cleared us to do so and had us hold short of 25L. We were then given clearance to taxi to the gate. During the taxi back I called operations and notified them we had rejected the takeoff and were returning to the gate. The captain directed me to inform the agent to have all ground personnel remain well clear of the tires; once parked most of the main gear tires went flat.I believe that the forward overhead door gave an open indication due to faulty rigging in the door mechanism. After we parked the plane at the gate we inspected the overhead door and found that by knocking on the door with ones fist the handle would vibrate out of the closed and locked position. I think that the vibration of the aircraft rolling down the runway caused the door handle to move and caused the door open indication.
