Tools required: Phillips screwdriver, plastic tool such as a guitar plectrum or credit card.
Remove your back cover, battery, sim and memory card. Now remove the six black screws you can see.
Open the slide and remove the two silver screws you can see, circled below.
Run a plastic tool such as a guitar plectrum or the edge or a credit card around the join of the back part of the phone in order to release it.
Your phone should now look like below. Two wires need disconnecting (circled). Each attaches like a plug and socket. Lift the connector up away from the phone to unplug.
Lift the circuit board from right to left. Another connector (circled) may disconnect as you do this. If not, disconnect it. The circuit board will still be attached to the phone on the left by the volume button strip. This is lightly stuck down and will peel away from the phone.
Your phone should now look like below. Two stickers cover two more silver screws. Remove the stickers, circled, then remove the two screws.
You can now remove the metal plate you have just unscrewed. Move it around a little until it releases. Now slide the ribbon through the gap in the slide mechanism.
Your phone should now look like below. Remove the yellow tape which covers the circled connector on the right. Flick the black hinge up to release the ribbon. The connector on the left attaches like a plug and socket, like the others.
Now carefully peel back the ribbon which is stuck to the back of the LCD screen. You can now lever the screen out (start near the bottom).
