The vibration motor's flex cable is very fragile. Work slowly to prevent tearing the cable.

Use the pointed end of a spudger, or a pair of tweezers, to peel the vibration motor's cable from the frame.

If the cable feels stuck, use a heated iOpener, hair dryer, or heat gun to soften the adhesive.

Use caution to not overheat the battery or surrounding components.

Remove the vibration motor from the frame.

Apply new adhesive to your vibration motor before installing it in the frame.
