Every time it "bricks". To rom boot it you disconnect the batteries for 5-10 minutes. Reconnect batteries. Key on for 5 seconds. Key off and connect to the truck with insite with the key off. It should be in rom boot when it connects. . Select calibration in insite and flash it with the key off. Sometimes I've had to do the procedure a few times to get it to rom boot. I'll try and find the actual document for it.

that sounds a bit sus to me. Maybe if the ecm only went into rom-boot?. I would think however that this would be pointless if the ecm actually bricked, as there is no mechanism it this key-switch dance procedure (or wiring harness for the engine) that will actually trigger the special 'rom-boot pin' properly on the face of that ecm.
