PS4 controller not working after replacing battery

I replaced the battery on my PS4 controller. I followed directions online but did a $@$*!& job and broke a bunch of clips, but it still holds together with all the screw in.

The PS button wasn't working so I did a reset with the little button on the back, then it paired. I'm at the user select screen. Analog stick works but d-pad does nothing (not sure if it should do anything here). X and O (only options given for keypresses on that screen) do not work at all. What could I have messed up here?
