Potentially ruined my steam deck (?)

Two weeks ago I found out that my right bumper was busted and doesn't press properly if at all, so being confident in my self, I diagnosed the issue being to do with the bumper assembly so I ordered a replacement from ifixit and tried replacing it.

A few hours later, and now my deck is back assembled but the bumper is still wonky, the trigger is rough, and I got booted into the steamOS boot menu and none of the buttons work. Connected a keyboard and chose the latest file to boot, and now I'm on steamOS with no working buttons, broken right bumper and trigger, and have to format my SD card.

Anyone know how to proceed from here?
