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.
