When dismantling any phone, great care should be taken to ensure that no damage is caused to any of the parts. Rough handling may result in severe damage of many parts, and if proper anti-static procedures are not followed, electrostatic damage may result in any electronic component.
Before commencing, it is recommended that the correct tools are purchased for the job in hand. At the very least, you will require a Torx T6 screwdriver, and for LCD replacement a sharp Stanley knife and small-tipped, low-wattage soldering iron. Do NOT attempt to use a small Allen key or filed down screwdriver, you will only damage the screws.
Step 1. Remove the front and back Xpress-on covers, keypad and battery.
Step 2. Using a Torx T6 screwdriver, remove the six screws marked in red, and keep them in a safe place.
.
Step 3. Carefully lever one of the two areas marked in red away from the side taking great care not to apply too much pressure, which could snap the plastic chassis of the phone. This will allow you to lift out both the screen/keypad unit and the main circuit board of the phone. Take care when handling the circuit board as it can be easily damaged by electrostatic discharge.
Step 3a. If you have followed the above steps carefully, you should now have the three main sections of your phone in front of you. Be aware that the earpiece although housed in plastic is easily damaged, often just by touching it. Also, the screen should not be subjected to any more than light pressure or damage may occur. Should you accidentally touch the screen, carefully buff any fingerprints or grease from it using a soft lint-free cloth.
Step 4. With just the main chassis of the phone in front of you, you are left with additional parts that can be removed or replaced which are marked on the picture below. 1. Power Button. 2. Buzzer Assembly. 3. SIM Card Connector Block. 4. Vibra Motor. 5. Data/power connector assembly, which also contains the microphone. The aerial can be seen clearly through the hole at the top of the phone. This can be removed by depressing the two tabs on the back of the chassis. The power connector assembly (below the aerial) can be removed by simply pushing it out, as can all the numbered items above.
Step 4a. This picture shows a view of the phone with the above parts removed. All parts are numbered as above.
Step 5. Extreme care should be taken whilst handling the main circuit board, which is prone to electrostatic damage. The only parts that can be removed from this are the three metal shields, which can be simply unclipped and lifted off the board.
Step 6. The screen/keyboard assembly. If you are replacing the screen, you will need to use a sharp Stanley knife or similar to remove the 6 plastic lugs marked in red which hold the metal shield for the screen in place. When you have replaced the screen, use a low wattage soldering iron with a small bit to melt the plastic back into place where it was originally cut off.
Step 7. To re-assemble the phone, carefully reverse all steps you have just taken to disassemble it. Once the phone has been reassembled, test all features to make sure that you have left nothing out nor caused any damage whilst inside the phone. Before replacing the front cover, it is a good idea to use the opportunity to clean the screen and the lens of the front cover. Do this with a soft lint-free cloth taking care not to apply too much pressure
