I don't care what's it gonna take. I just want a connection. I guess I can connect the VCC to another voltage source, but I have the same thing happened to TX on another circuit board, although that one can "flip" (it is still attached marginally... at one end).

Board: T Deck Lilygo.

Should be easy. When you follow the lost pads' trace, it goes through a through-hole just above the RTX pad. Scratch it free, solder a small wire in there (verify that you've got contact!), then solder the connector onto the remaining pads and solder the wire to the VCC pin of the connector.

Pro tip: Don't yank on the cables!

I yanked a connector that I wanted to remove. I don't have needle thin nippers/pincers, and when I held my iron against the pads nothing happened. Am I missing something?

I guess a good set of nippers, but idk man...
