The Home Of Dismantle Instructions For Mobile Phones

Siemens A55 & Variants

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, a Torx T5 screwdriver will be required. However, the T5 is extremely difficult to get hold of, so you may have to manage with a slightly worn T6 instead. If you do use a T6, be very careful not to damage the screw heads.

Step 1. First of all, remove the front and back covers, the keypad (if it doesn't come away with the front cover), the battery and SIM card.

Step 2. With the main phone exposed, you will note that there are 6 T5 screws marked here in red.

Step 3. Once the 6 T6 screws have been removed, you can gently (but firmly) separate the main circuit board from the chassis of the phone by simply lifting the circuit board away.

Step 4. A little caution must be exercised with this step to avoid damage to the thin metal shield shown to the left below. Take note of the small pin shown highlighted below in purple. This is made from plastic, and can easily be broken if too much pressure is exerted. Using a smallish flat bladed screwdriver, lever the metal shield off the plastic locating pin at the bottom of the phone. Once the shield is clear of this pin, raise it slightly away from the bottom of the phone and gently turn the shield clockwise to disengage the locating lug that locates behind the screen.

Step 5. There isn't much more that you can easily dismantle from the main circuit board, as the keypad assembly appears to be glued to the circuit board. However, in the main chassis, the vibra motor and microphone can be simply removed by lifting them out of the chassis. Take care not to over handle the microphone or damage the two sprung contacts.

Step 6. Putting the unit back together pretty much requires doing the reverse of all the previous steps! After reassembly, take time to check that everything works as it should do, and that you have caused no damage whilst inside the phone.
