Mechanical Working Instructions
1 Disassembly
1.1 Process tools
· · Front-disassembly-tools. Torque screwdriver, torx no.6 pre-set to 33 Ncm.
1.2
Instructions
NOTE! Keep all contact-surfaces/display clean of skin oil. Use gloves! 1. Remove the battery. 2. Hold the phone upside down. Open the flip until it points 90° outwards and press your thumb on the hinge (fig1.1). 3. Remove the flip by placing your thumb on the outside and your fingers on the inside and press it off the hinge (fig1.2). 4. Carefully pull out the other hinge. NOTE! Be careful, the connector-pins will easily stick into the mic. cable. 5. Remove the antenna by slightly moving it side by side at the same time as pulling it out from the phone (fig1.3). NOTE! Don't break, the antenna holder/connector may be damaged. 6. Hold the phone with the frame towards you. Place one of the front-disassembly tools in the small slot between the front and the frame, in the middle of one side (fig1.4). NOTE! Be carefully, don't slide with the tools, the frame or the front will easily be scratched. 7. Without breaking, bend the tool upwards while pressing/forcing it all the way under the front cover until the green handle comes into contact with the frame and leave it there (fig1.5). NOTE! You are not allowed to break with the tool or slide with it, only push it under the front 8. Repeat previous step with another tool on the opposite side (fig1.6). NOTE! The green handles on the tools must come into contact with the frame, otherwise the front cover will not come loose in next step! 9. On the top, place the last tool in the small slot between front and frame. Bend it towards you (fig1.7). 10. Carefully pull off the front cover by lifting and turning it around the system connector (fig1.8). NOTE! Carefully so you don't damage the snap holder in the front or stretch the miccable. 11. Disconnect the mic-cable from the board (fig1.9). 12. Remove the four display assembly screws (fig1.10).

Mount two short screws in the lower corners of the carrier and tighten them with the torque screwdriver (fig3.5). 9. Make a visual control there are no fissures in the front cover and its snapholders. 10. Rotate the mic-cable contact inside the front until the cables are pointing downwards and hold still with your thumb. Fit in the connector-pins and guiding pin in the front with the flip wide open. Press your thumb on the hinge (fig3.6). 11. Place your left thumb on the inside of the flip and your fingers on the outside and press it on in the wide-open position (fig3.7). NOTE! You can use a screwdriver to push in the plunger. 12. Close the flip and check the contact between the mic-cable and the flip is properly inserted all the way in and with the cables pointed upward (fig3.8). 13. Mount the mic-cable (still mounted in the front cover) on the board with the cables pointed downwards (red cable to the right) (fig3.9). NOTE! Carefully so you don't stretch the mic-cable. 14. Control there is no dust/dirt on the display or on the inside of the window. 15. Mount the phone by first pushing the frame into the top of the front (fig3.10). NOTE! Make sure that the volume button is in its lower position. 16. Control that the mic-cable is into the cavity between the hinge and the spring.
