Introduction

This guide walks you through the steps to replacing the XV6700 motherboard.

Tools

Step 1

Press the on/off button on the top to power the phone off.

Step 2

Remove the battery cover by pressing and sliding the cover down and off of the phone.

Step 3

Pull the battery removal tab and lift the battery out of the phone.
If the battery removal tab is missing, place a spudger on the opposite side of the highlighted connector and pry the battery up.

Step 4

Remove the two 4.0-mm #000 Phillips screws at the top of the battery compartment. Tweezers may be useful to remove the screws.

Step 5

Use firm pressure to carefully pry off the cover with your fingers.

When putting this cover back on, you need to align the little focus dial/switch next to the camera (under the cover) with the one on the cover, so that the one on the cover can be over the switch below.

Step 6

Remove the 4.0-mm #00 Phillips screw securing the camera flash circuit board. The board is still connected by a connector on the bottom of the board.

Step 7

Gently pry off the camera flash circuit board with the spudger.

Step 8

Gently pry off the camera with the spudger.

Step 9

Remove the four 5.0-mm Torx T6 screws from the corners of the black cover.

Step 10

Remove the 4.0-mm #00 Phillips screw that holds the antenna in place. The antenna does not need to be removed.

Step 11

Use the spudger or plastic opening tools to apply firm but gentle pressure equally around the outside of the case.
Carefully pry the black portion of the case away from the silver portion.
Do not try to remove the case completely. The speaker wire is still connected to the motherboard.

If the stylus is still inside the antenna, then you have to remove it before doing this step.

Step 12

Using tweezers, pull with gentle pressure in the direction of the wire to unplug from the motherboard connector.

Step 13

Remove the 4.0-mm #00 Phillips screw holding the motherboard in place. The screw is in the middle of the motherboard, near the outside edge.

Step 14

With your fingers, disconnect the keyboard cable from the motherboard. The cable is orange with the letters T/B printed on the connector.

Step 15

Carefully lift up on the motherboard with the spudger until you can see the display cable connected to the underside of the motherboard. The display cable connector will be taped over.
