Pry open the bottom of the camera with the opening tool or screwdriver. The front panel should come forward, but must be lifted (pried) over the tripod mounting. It may help to slide a small screwdriver under the panel via the battery door.

Once you've slipped the front cover's base over the tripod mount, gently pull it away from the camera body.

Do not remove the screws on the metal lens mount ring. Doing so may cause issues with auto-focus.

See that thing that looks like an AA battery? That is actually a very large capacitor to charge the flash to high voltage. Do not go near it with any metal object. Do not touch the two leads at the bottom. It can give you a very serious shock, even without the battery installed!
