Dismantling Nokia 3410 & Variants

Back to: Nokia Dismantle Instructions

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. 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 at the side of the screen 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. 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. Battery power connector. 2. Vibra motor. 3. SIM Card Connector Block. 4. Buzzer assembly. In addition, the photograph below also shows the rubber power button which is removed by just pulling away from the phone chassis, and the base connector housing the charging port, headphone port etc. Again, this is removed by simply lifting out of the chassis. 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.

Step 4. 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
