Take off the back covering of the phone along with the battery and SIM card.
The SIM card is located above the battery.
Using the Phillips #00 Screwdriver, take out the four small screws located at the four corners of the phone. Save the screws. They will be needed for reassembly.
Using the same screwdriver, take out the two bigger screws located on each side of the battery compartment. NOTE: Save the screws. They will be needed for reassembly.
Once all the screws are removed, use the iPod opening tool to pry off the back covering of the phone along the edge of the back cover and you will have access to the motherboard. Note: The power and volume buttons will fall out of the phone. Set aside for reassembly.
Carefully pull the backing of the phone from the motherboard with your hands.
To remove front case from the motherboard, first pull back the silver tab (highlighted in blue) and the orange tab (highlighted in red).
Once the silver and orange tabs are pulled back, carefully pull the motherboard apart from the front case.
For reassembly: Place the new motherboard on the front case.
Snap the tabs back into place. Replace back casing and snap in place.
Screw in screws. Note: you can also follow these steps in reverse, which is the same process as outline above. Note: replacing the power and volume buttons may be tricky. For ease, use tweezers. You have now successfully replaced the screen for the phone.
