I managed to finish the repair. Ended up with several stripped screws, which took even longer to take out. I would suggest on using an even smaller tip phillips screw driver as the one suggested here was too big for most of the screws. And after all the frustration, money, and hours of replacing my volume buttons. They still don't work on one of them. I've wished I didn't go through all that. Now I have to take it to a repair shop to find out what it is that's wrong. My suggestion, unless your an experienced technician with steady hands. I would take to a repair shop instead. Not for the timid.
I would suggest using both the clear tab and the plastic opening tool simultaneously to be able to remove the battery.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
