Introduction

There are two speakers in the HTC EXCA100. We will be replacing both - the speaker used for the ringer and speaker phone, and the speaker used for the ear piece.

Remove the rubber screw covers. If needed, use a thin object to help pry them off. There should be two of them on top of the phone. Skip this step if already removed.

After removing the rubber stoppers on top, there should be six exposed screws. Remove these using the T6 screwdriver. Next, use the spudger to loosen the case underneath the shiny metal edge. Go all the way around the phone until completely loosened. The case is superglued on and will not permanently damage the phone when removed, but you should still use caution.
