Ehh.. I like the tapping idea. The less you mess around inside that charging port, the better. You may also want to try a small screwdriver, very small like the kine we use to repair phones and such, and gently pry downwards, on each side, until it comes out. Or at least, until it comes out, where you can pull directly, like with your fingers. Oops, forgot to say, make sure the thing is powered down
