• Turn your phone over so the back is facing you. Remove the back cover, battery, sim card and memory card. Remove the four screws you see in the battery compartment

• Next using your needle or pin begin to pry the plastic cover at the bottom of the phone off. Be sure to only lift the plastic with the pin or needle and then pull it off with your fingers to avoid scratching the phone. With the cover is removed you can remove the two screws.

• You can now remove the back cover of the phone by running your fingernail along the join of the housing and carefully prising it away from the rest of the phone.

• After the two pieces are seperated you see two ribbon cables which connect the screen and main. It is important not to pull on these cables with too much force because they can rip easily. On top of the two connectors you should come across a black piece of tape. Using the pin or needle start to pull this tape away. Save this piece of tape to place back over the connectors when you are done. Mark each connector "L" (left) and "R" (right) with a permanent marker. Gently pull the connectors from their sockets.

• Once the connectors are removed then the phone will be in two pieces, as below

• Use the Phillips screwdriver to remove the four silver screws which hold the keypad cover to the hinge. Now use the needle or pin to lift the plastic cover at the top and again use your fingers to pull the cover off. Using the torx driver, remove the two screws under the cover. Near the hinge you will find two more torx screws. Remove these as well.

• Now using your fingernail carefully begin to split the housing. As you run your nail around the edge of the case it will start to separate. Slide your nail all the way around until the two parts separate.

• Using the Phillips head screwdriver, lift the hinge part, indicated by the arrow, from the case. To get the wires through the hinge you will need to carefully push the connector through the hole in the centre of the hinge. Try not to bend the cable too much.

• Now that the hinge is removed you can remove the LCD from the housing. Carefully apply a little pressure around the edge of the housing until the screen pops out. Replace the old screen with new. Reverse the whole process for reassembly and the job is complete
