* Remove the battery, back cover and your memory card.
* Remove the two screws you see. Two screws are covered with rubber stoppers. Lift those out with something like a bic pen lid then remove these screws too.http://www.formymobile.co.uk/Dismantle/w89010.jpg
* You can now remove the front cover by running your fingernail all round the edge of the housing
* You'll now have the front cover removed, like below.
* Now lift the circuit board from left to right. The circuit board will still be attached by a ribbon so don't try and lift it away from the phone yet.
* The ribbon, indicated by the screwdriver in the picture below, attaches like a plug and socket. Simply lift it up to unplug it.
* Your phone should now look like below.
* Lift the green part shown below (it's held in place by a couple of clips around the edge) and you'll see three more ribbon connectors. Unplug the middle one
* Now turn the phone over and lever the old screen out
* You can now remove the LCD screen and replace with new. Reverse the whole procedure for reassembly.
