You cant remove the hinge pins without drilling them out. What you should do is take a dremel or air cutting tool, and modify the hinges, its really easy andwhen its done a door comes off in less than 5 seconds. That is if you have done somthing to your door straps, like make some door straps with buckles or somthing. thats what i did.
Theres articles all over the place for modifying your hinges.. im sure youll love it when your doors are off.
I just took the screws out. I don't like the idea of cut hinges. I don't know why I dont, I just don't...
If you remove the screws save yourself some dents and drill the heads off. If you do it correctly you can pultt eh screw shafts out once you take the door off. I'll explain more if you are interested enough to email me.
