Opening the orange screw may void your device's warranty.

Use a guitar pick to unclip the back cover, especially on newer models where it's quite difficult.

Be careful not to break bigger clips; they may reattach with smaller ones. If this happens, consider replacing the back cover before proceeding.

Removing the battery and NFC antenna separately can damage the antenna.

Remove the 8 Phillips screws securing the motherboard cover using a screwdriver.
The screws also hold the motherboard in place, with two additional screws underneath for extra security.

Do not touch the golden ribbons or force the cover, as the NFC antenna is glued to it.

Let the cover fall over the motherboard without re-clipping it.

Remove the upper screen ribbon by releasing its clip.

Be careful: removing the motherboard incorrectly can result in damage.

Unscrew the two Phillips screws near the black circle (vibrator) and camera.
Lift the motherboard gently, starting from the vibrator area, to access the clipped volume and power ribbon.

The ribbon should unclip if factory glue is properly applied. If not, proceed with caution or consider replacing the volume/power assembly with the screen.

Remove the vibrator using a plastic tool, as it's held by double-sided tape.
Locate and remove the hidden screw between the jack and upper screen ribbon.
Disconnect the proximity sensor and jack ribbons, taking care not to damage them.
Remove the speaker, which should come out easily.

Remove three screws holding the dock in place.

Apply a mediator to the upper left corner of the dock and slide it downward to unclip it.

Damage to the antenna wire can result in a "No Service" condition.

Unclip the antenna wire from its retaining clip.
Pull slowly on the wire to release the plastic/rubber retainer holding it in place. Remove both pieces.

Incorrect clipping of the antenna wire or damage can cause no service.

Remove lower ribbon carefully with plastic tools to prevent cuts.

Use a plastic tool to lift the ribbon with the help of the USB dock and remaining wire.
If you purchased the volume ribbon, you are finished.
Otherwise, use a cutter blade from the top of the phone to remove the ribbon.

Using a very slim blade is essential for removing the sound and On/off ribbon without damaging it.

Choose a blade that's not too sharp, as cutting the ribbon will ruin it.
Insert the blade into the metal track (black) and slide it along to release the ribbon.

Be gentle when lifting out the connector or you may accidentally separate the buttons from the ribbon.

To avoid future issues, consider ordering a new ribbon designed for touch screens (approximately $2 extra).
