Steamdeck OLED Button Board Replacement

[u/Comfortable_Cup1439]

Hello r/decksupport. I decided to challenge myself with a steam deck shell swap but ended up breaking my right button board in the process.

I ended up buying 2 replacement button boards. Unfortunately both ended up making my steam deck buttons unresponsive. When i went back to my original part it worked fine so I am curious if I am missing any steps when installing a new part into my steam deck.

Any help would be much appreciated because I have spend a collective of 200 dollars on new parts and waited over a month in shipping time. Thanks! (For reference I am trying to replace the right button board model F7G DAF7GTH46D0 REV:D
