Trunk access with no power at all.

Hey guys! Just wondering if anyone has any ideas how to get in to my F07 trunk. So here's the case. I left the town for a week or so and it got really cold (about -25C) so when got back, I found the car completely powerless. Tried to plug the power cables to another car, ignition is on, though cant start, just hear a pop when it tries to start and that's it. Now here's the tricky part. I tried now to plug the cables to another car so I would get a bit of power to open the trunk so I could access the battery, but before I tried to start it again, the "poppping" sound was significantly louder and at this point the car is again - powerless but I can't even power it up through the cables, when I connect, there is no spark when attaching the cable and it the car doesn't react to anything at all. Any ideas what could that be? Since I can't hook it up with cables, I cannot access the trunk to get the battery out or replace it with another one so I could drive it to the service.
Any ideas would be appreciated thank you!
Tom

My GT isn't that new too, it's '10. I have looked through the manual but there is nothing about opening the trunk without using the buttons on the car or remote, nor there is information about where could be the starting aid terminal fuse located so I could replace it and hook up cables from another car.

It sounds like you were able to get into the cabin to open the doors and check the fusebox. The charging cables would go onto the lugs in the engine compartment. If you tried to jump the car from one of the accessory sockets, you will have blown the fuse. The plus terminal is protected by a red plastic cover, and the ground lug is closer to the front of the car. If the battery is really flat, it could take 15-20 minutes or more to start to bring the level up enough to do much of anything.

There's an internal, emergency trunk release handle. It's made of plastic that can glow a bit in the dark. I don't remember if you can fold the rear seats and partition from inside the cabin, but if you can, then you should be able to then reach that emergency release handle. That is a standard part, so should be on your vehicle. It's sort of a T-shaped bit.

Yes, I am able to get into the car with a key. I have tried to jump the car with the plus terminal in the engine compartment (under the hood), and yes probably I have blown a fuse. Any ideas where that fuse is so I could replace it? I am not able to get into the trunk from inside of the car, the rear seats pull down but there is no way to get in because the three part "wall" between the seats and the trunk can be opened only from the inside of the trunk. So I think the only way is to get the plus terminal working again (find and replace the fuse) and then power it up with the cables to get just enough power to open the trunk so I could service the battery. I was able to get the car powered up enough for electronics to work, but not to start the engine. Any ideas where that fuse for the plus terminal could be?

When connected to the cables, yes, there was enough power to see electronics. Tried to start,
heard a POP, power does not go through the plus terminal anymore (probably blown a fuse or something), therefore no power at all, so no way of opening the trunk and accessing the battery anymore.
