Put in the first screw and make sure it fits, door closes and latches fine without problem before moving on to the second screw.

Once all screws are in place and the door latches, take a mental note of the placement and depth of the screws.

Pull out the screws one last time, and put in a drop of loctite or super glue and then put the screws back in making sure to get the proper screw back in the hole it came from and making sure to match the depth it had before.

Let your camera sit for 24 hours (or however long you can) and then enjoy! This is a very strong and possibly permanant fix for your camera!
