Soldering is the most challenging task of this repair, but beyond the scope of this guide. Always ensure adequate ventilation, and use respiratory and eye protection.

The soldering results displayed in this guide are amateur and achievable by those with intermediate skills. Practice and patience are the key elements of success.

After soldering, use a multimeter or stand-alone continuity tester to verify that each pin of the connector has continuity with only the expected USB plug contact, as mapped in the previous step.

Each twisted pair of the cable has its own shielding that must be joined and linked to the black wire of board connector pin 8.
