Have you tried charging from the booster ports under the hood? This should at least give you some accessory power to pop the trunk. Sometimes in order to trick the charger and force a charge on a completely dead battery, Ill hook another battery up to the car and hook the charger up. This will get the charger going, and a half hour later Ill pull the god battery off, and the charger usually does the rest.
