iPod Touch 4th Generation Home Button Ribbon Cable Replacement

With the heat gun set on "low", begin heating the lower portion of the Touch near the home button.

Insert the edge of an iPod opening tool between the front glass panel and the plastic bezel near the home button.

Pry the bottom edge of the front panel upward, being careful not to bend the glass excessively.

When there is enough room to grab the bottom edge of the front panel, lift it away from the body of the Touch to peel up the adhesive along its left and right edges.

Carefully pull the top of the front panel assembly away from the adhesive holding it to the Touch, minding the short digitizer cable connecting the two components.

Remove the following eight Phillips #00 screws:

One 3.5 mm Phillips screw

Two 3.0 mm Phillips screws

One 2.3 mm Phillips screw

One 2.4 mm Phillips screw

Three 2.0 mm Phillips screws

Use the edge of an iPod opening tool to pry the thin steel cover up from the rear-facing camera.

Remove the steel cover from the iPod.

Insert the edge of an opening tool under the steel mid plate near the bottom left corner of the Touch.

Slowly pry upward to separate the plate from the adhesive securing it to the plastic inner case.

If the plate is still attached to the logic board, re-warm the area to loosen the adhesive, then slowly separate the plate from the logic board using the opening tool.

There is a thin, fragile ribbon cable underneath the plate. As you pry the plate up, be very careful not to rip the cable.

Slightly tilt the steel mid plane to dislodge it from the rear case.

Lift the steel mid plane up off the rear case and peel off the piece of copper tape stuck to the rear-facing camera.

Peel the home button ribbon cable off the front side of the steel mid plane using a plastic opening tool.

In the same manner, peel the home button ribbon cable from the back side of the steel mid plane.

Remove the home button ribbon cable from the steel mid plane assembly.
