Tools required for disassembly: Phillips screwdriver, Mobile phone opening tool

First remove your back cover, battery, sim and memory card. Next remove the four screws, circled below in red, which hold the loud speaker in place. Now use an opening tool to pry away the loudspeaker along it's top edge, as shown below. The loudspeaker is now free. Next remove the other five screws, circled below. Now run your opening tool all the way around the join of the battery compartment and the battery compartment will come loose. Next disconnect the two cables circled in red. Each has a plug and socket type connection, so simply lever each connector up. Circled in white is the antenna cable. Again. this has a plug and socket type connection, so simply lever the connector up, away from the circuit board. Now remove the metal clamp by levering it from the point indicated by the arrow below. The metal clamp is now free. Now lever from the points shown and the long flex cable will come away. A small amount of adhesive tape holds the part in place. The flex cable is now free. Next lever away the black, metal clamp indicated by the arrow below, then disconnect the two ribbon cables circled in red. Again, these have a plug and socket type connection, so simply lever each connector up, away from the circuit board. You can then lift the front facing camera and proximity sensor/earpiece away. 

Below you can see the clamp, front facing camera and proximity sensor/earpiece, having been removed. Now disconnect the three ribbon cables circled in red. Again, each has a plug and socket type connection, so lever up, away from the circuit board. Also remove the screw you can see, circled in white. You can now lift the circuit board away from the rest of the phone. The circuit board is now free, as shown below. To remove the main camera, turn the circuit board over the disconnect the ribbon cable circled below. Again, this has a plug and socket type connection, so lever up, away from the circuit board.  The main camera is now free. To remove the sim and memory card readers, first heat the part for around 30 seconds with a hot air gun or hair dryer (this softens the adhesive tape holding it in place), then slide something thin and flat, like a guitar plectrum or credit card, under the part from the point indicated by the arrow. The sim and memory card readers are now free. To remove the vibrating motor, circled below left, apply some heat and then lever it free. To remove the headphone socket, circled below right, remove the screw next to it then simply lift it free. The vibrating motor and headphone socket are now free and can be reattached to your new screen, along with all the other parts. Disassembly is now complete.
