Open the phone just enough to reveal the metal bracket covering the home button cable.

Do not open the phone too far or you risk damaging the home button cable, or the socket it plugs into. Keep the cable loose—if it is stretched taut, that's too far.

Only the phone's original home button assembly will be capable of using the Touch ID functionality. If you rip the cable, installing a new home button will only restore ordinary home button functions, not the Touch ID features.

Use the tip of a spudger to push the bracket free and remove it with tweezers.

The next two steps apply to reassembly. Skip them and continue to Step 12 until reassembly.
