With a piece of jump wire or thin regular wire (AWG32 and thinner) connect the display cable pin above torn pad and related tinned track area (from step 4).

Put a drop of flux paste above this. Carefully solder both wire ends to cable and track while keeping the wire in place with tweezers.

Inspect the area for accidental soldering bridges. Remove them if any.

Cut the free wire left behind track soldering with a scalpel.

Clean the area.
