Tools required for disassembly: Phillips screwdriver, plastic tool such as a guitar plectrum or credit card.

Remove your back cover, battery, sim and memory card. Now remove the ten screws you can see, circled below. Next, slide something thin and flat, like the edge of an old credit card, all the way around the join of the battery compartment, as shown below. This will release the battery compartment. The battery compartment is now free. Two ribbon cables, circled below, now need to be disconnected. Each has a plug and socket type connection, so simply lever each connector up, away from the circuit board. Now lift the circuit board from right to left and you'll see another ribbon cable. Again this has a plug and socket type connection, so simply lever the connector up, away from the circuit board. The circuit board is now free, as shown below. The ribbon cables which connect the front and rear facing camera to the circuit board are circled below. If you wish to remove them, refer to the next stage of the guide. Circled below you can see the ribbon cables for the front and rear facing cameras. Each ribbon cable is connected via a zif connector. The pink/brown part is a latch that opens and closes on a hinge. Carefully flick the latch over, away from the ribbon, and the ribbon will be free. Below you can see the zif connectors with each latch in the closed position. Refer to the next stage to see each latch in the open position. Below you can see the zif connectors in the open position. You can now remove the cameras by simply pulling them away from the circuit board.  The front and rear facing cameras are now free. To remove the loud speaker/antenna/jack socket, first remove the screw circled below. Now turn the circuit board over and you'll see another ribbon cable, circled below. Again this has a plug and socket type connection, so simply lever the connector up, away from the circuit board. Now lift the white plastic part, indicated by the arrow, away from the circuit board. The loud speaker/antenna/jack socket is now free.  Going back to the screen, first remove the vibrating motor, circled near the top of the phone, and the memory card reader circled near the bottom of the phone. To remove these parts, first apply some heat using a hot air gun or hair dryer. This will soften the adhesive tape holding the parts in place and you'll be able to lever them free. Next remove the power and volume buttons, indicated by arrows 1 and 2. These buttons simply lift free. Next lift away the grey microphone cover, indicated by arrow 3. Lastly, peel back the ribbon cable indicated by arrow 4. It's held down lightly with double sided tape. The power button, volume button, vibrating motor, memory card reader and microphone cover are now free. To separate the screen from its frame, first heat the front of the screen for around 60 seconds with a hot air gun or hair dryer. This will soften the adhesive holding the screen in place. Then carefully push something like the end of your screwdriver into the recess indicated by the arrow below. This will raise the screen slightly and allow you to slide your plastic tool under. Carefully slide your plastic tool all the way around the edge of the screen. Keep applying more heat and keep pushing your tool further under the screen. Be very careful around the ribbon cable and near the soft keys at bottom of the screen. The screen is very well stuck down, so take some time, be patient and the screen will eventually come away. The screen is now free. The home button, indicated by the arrow below, can be simply lifted away. The home button is now free. The gauze for the earpiece is indicated by the arrow near the top of the image shown below. This can simply be lifted away. The ribbon cable for the soft keys, indicated by the arrow near the bottom of the image, is stuck down lightly with adhesive tape. If you need to remove this part, apply some heat then carefully peel it away. Disassembly is now complete. Reverse the whole procedure for reassembly.
