Use a pair of tweezers to pull the home button flex cable straight out of the ZIF connector.

Gently peel the flex cable off the home button cover and fold it a little bit upwards.

If needed, apply more heat to soften the adhesive under the flex cable and make it easier to remove safely. The cable is very fragile. If it gets damaged, or if the home button has to be replaced, Touch ID will no longer function.
