Solder all 30 pins back to the logic board.

Heat all 30 pins with the tip of the soldering iron.

Melt a drop of solder onto the pins and spread it around with the tip of the soldering iron.

Repeat until all pins are covered in solder.

Make sure solder covers every pin and pushes through to the other side of the logic board.

DO NOT push too hard on the pins with the tip of the soldering iron as you could bend the pins.

Remove any excess solder with desoldering braid.
