Nintendo Switch Pro Controller Seemingly Dead

Hey everyone, my switch pro controller has been dead for almost a month now, and I still have absolutely no clue what could be causing it. I originally opened it to investigate a broken minus button, however, somewhere along the way the controller stopped working with the battery. Maybe I shorted something, and honestly I have no clue what I could have done, but whats even more confusing is that shortly after it stopped accepting any power from the charge port. Luckily, I have a second pro controller that I can use to test, and I know that the battery, ribbon cable, and front button assembly is fine. I still need to test if the rumble modules are needed to be connected, since I ripped the orange ribbon cable like a dummy, but I don’t think the controller needs the motors to turn on. Any help from you guys would be greately appreciated so I can get this back up and running.
