Pry the rear cover from the back of the phone.

Remove the four 5.0 mm T5 Torx screws from the corners of the phone.

Remove three 5.5 mm T5 Torx screws from the back of the phone.

Lift up the black rubber flap near the SD card slot.

Remove the single 5.5 mm T5 Torx screw beneath the flap.

Remove the back case of the phone by gently lifting the tabs located on top of the phone near the lock button.

Use the case opener or spudger in these small areas because the plastic tabs can be easily broken.

Lift the tabs located on the bottom of the phone to continue removing the back cover.

Slide an opening tool between the gap from the back of the case to the front.

After separating the sides, make sure there is a noticeable gap between the back case and the rest of the phone.

After detaching the tabs and sliding down the sides, there should be a noticeable gap between the front and back cases.

Carefully separate the back case from the rest of the phone by lifting it away from the phone.

Disconnect the antenna from its housing on the motherboard by gently lifting beneath it.

Ease the antenna from out of its guide along the side of the phone

To remove the motherboard, first dislodge the right side of the motherboard, where the external connections are located, from the rest of the phone.

This can be done by placing a spudger in between the two ports on the phone, between the black plastic and motherboard, and prying out.

The motherboard should be able to be easily lifted upwards after dislodging it.

If the white rubber piece moves, replace it where it came from upon reassembly.

First, several connections must be disconnected to completely separate the motherboard from the rest of the phone.

The connection highlighted with a red box must be pulled down instead of out.

Using the spudger tool, separate the two connections on the motherboard highlighted with orange circles by pulling them out.

The black switch on top of this connection acts as a lock. Push it forwards to unlock the connection.

After disconnecting the motherboard, there should be five distinct and separate parts of the phone: back cover, back case, front case, battery, and motherboard.

The speaker can be found on the bottom of the inside of the back case and is held in by glue.

Use a spudger or case opener tool to pry out the speaker by sliding it in the crack between the two pieces of black plastic.
