Tools required: Torx 6 screwdriver, plastic tool such as a guitar plectrum or credit card.
Remove your back cover, battery, sim and memory card. Remove the six screws you have access to.
The front cover will now be loose and can be removed.
The battery compartment will also be loose and the phone can be separated again, as shown below
Release a clip on the right side of the plastic part shown below then lift to the left to reveal a ribbon connector (circled). This attaches like a plug and socket.
Simply lift each connector up, away from the circuit board, to unplug it.
Your phone should now look like below. Another ribbon connector (circled) needs to be disconnected. Again, this is a plug/socket type connection.
Turn the phone over and remove the two circled screws.
You should now have the LCD screen removed, as shown below. Reverse the whole procedure for reassembly.
