Cracked your digitizer? Need to replace the LCD? For the Centro and the majority of Treos, a quick trip to YouTube is all you need to do to find disassembly instructions. However, no disassembly instructions are available for either device. In this article, we’ll be showing you how to disassemble the Treo Pro!

Before you begin, note that you are performing this repair at your own risk and that the warranty on your device will be voided.

Tools Required

For this disassembly, you will need a Torx T5 screwdriver, Philips screwdriver, and a small flathead screwdriver.

A plastic pry tool is not required for this disassembly as a fingernail will suffice, however, if you do not wish to use your fingernails, a plastic tool may be substituted. Do note, however, that a plastic tool is more likely to incur damage on the device than a fingernail.

Step 1: Preperation

To begin the disassembly, remove the battery cover, battery, stylus, lanyard (if applicable), and microSD card.

Step 2: Remove screws and the antenna assembly

There are five screws on the back of the Treo Pro. Remove the screws, and lift the antenna assembly from the top and set it aside.

Step 3: Remove the back cover

Beginning at the top, run your fingernail down the side of the device. Begin with the right side and release the tabs on the side of the device all the way down to the bottom.

After the right side is released, run your fingernail down the left side of the device. The back cover is still held in place on the bottom by a tab and the USB port. Rotate the back cover counterclockwise to release.

After the back cover is removed, a rubber piece may be left behind on the motherboard. For easier reassembly, place it back on the inside of the back cover and set the back cover aside.

Step 4: Remove the main board

There are three screws holding the motherboard in place, one black screw at the top right of the motherboard, one black screw at the bottom left, and a silver screw near the middle of the right side.

In the bottom right corner, there is a sticker covering the keyboard and digitizer ribbon connectors. Remove the sticker. Lift the tab on the ribbon cable connector, and remove the ribbon cable.

The digitizer ribbon cable does not have a lock and can be pulled straight out. Lift the left side of the motherboard carefully (as the LCD cable is still connected) and remove the LCD connector. Remove the motherboard.

Step 5: Remove the LCD

Insert a small flathead screwdriver into the upper left corner and gently pry the LCD out. Be careful not to touch the LCD or the digitizer as dust or contamination may get trapped between the LCD and the digitizer during reassembly.

Step 8: Remove the keyboard

To remove the keyboard, pry the bottom loose and loosen the tab on the right side of the keyboard. Slide the keyboard to the right to remove.

Step 9: Remove the digitizer

This is the trickiest part of the disassembly. The digitizer is held in place through the use of adhesives on the front side of the faceplate. Because the Windows key and OK button are attached to the digitizer, the backing on the buttons must be removed first. Insert a small flathead screwdriver undernearth the clear backing and pry it off. Note that the adhesive may stick to the backing or to the digitizer, so reposition if necessary.

To begin removal, remove the speaker at the top of the faceplate. With the speaker removed, gently push on the plastic lens. Insert a fingernail into the gap between the digitizer and the faceplate, and run along the sides. Lift the digitizer away.

Step 10: Re-assembly

Congratulations! Your Treo Pro has been fully disassembled. To reassemble the device, repeat the steps in reverse. If you have a can of compressed air, I would strongly advise that you clean the LCD and the inside of the digitizer before reassembly and inspect before continuing.
