-
DO NOT pry loose as shown in this picture. The button in the middle that is pictured can be pressed in, releasing the back housing which can then be easily lifted free.
-
-
-
Using a plastic pry tool, at the top, the right and left sides and the bottom, carefully insert and pry to pop loose the plastic frame from the LCD/Touchscreen Housing.
-
-
-
Remove the one Phillips head screw from the motherboard.
-
Remove the silver tape/adhesive covering 2 jawbone connectors.
-
-
-
Remove the same black plastic from the top power button. Be careful to only remove the plastic as there is a flex cable under.
-
-
-
With the power button flex up you can now carefully pull up the motherboard.
-
On the underside you will barely see the jawbone connectors. Go ahead and flip them open to release the cables.
-
-
-
Before lifting up the motherboard, be sure to release the 2nd jawbone connector. This one is for the touchscreen/digitizer. (Photo is with motherboard already out to show you exactly where it is.
-
With the flex cable removed you can now lift up on the motherboard. There is still a cable attached, but it is the touchscreen/digitizer cable. So, if you have a broken screen it IS ok if you break this cable.
-
-
-
Now can you completely remove the motherboard.
-
There are little "teeth" around the mother board so if you are having some trouble it's because the motherboard is still caught under the teeth.
-
-
-
Using a heat gun, carefully heat the glass all around the screen. Be careful not to overheat as this can cause damage to the LCD.
-
-
-
Starting at the top and then going down the sides, carefully insert a plastic pry too and begin to separate the touchscreen glass from the LCD assembly.
-
Be careful as you get to the bottom when removing the glass. There is a thin strip that needs to stay in tact.
-
When at the bottom you will notice a white strip. Do not tear this or the buttons on the bottom of your screen will not light up!
-
Go ahead and remove the glass completely.
-
-
-
Remove the top layer of sticky black tape, then prep the LCD assembly and new touchscreen/digitizer with new adhesive--I just used thin strips of two-sided tape.
-
Using a microfiber cloth remove any dust from the LCD display.
-
Slide the new touchscreen/digitizer cable between the frame and LCD display.
-
Once the cable is through go ahead and remove all paper from adhesives and set the screen in place.
-
Now you can begin reconstructing your phone. Go ahead and go through the steps backwards.
-
Reattaching the cables is the trickiest part but not impossible.
-
To reassemble your device, follow these instructions in reverse order.

Hello, good afternoon!
I wonder what the material used between the screen and the lcd display?
I realized that there is a sort of black film behind the touch screen. What would it be?

Be extremely careful when removing old digitizer out of frame & when placing a new one! I have broken my LCD because of the pressure I applied to the screen.
What?! You just press the button and it comes apart. DON'T pry anything apart or you'll probably break the mechanism that keeps the cover on!

I would like to point out that with a lot of smartphones these days, there isn't a button you can push that will simply pop off the back casing. Anymore, you NEED pry tools to remove these things, because the mechanism holding them there is a simple hook that clicks into place. It's all a solid piece, but you can normally remove back casings without doing damage to the phone. The manufacturers will typically have an area on the phone where you can pry from without causing damage, and if you do it slowly, carefully, and gently, you should have no problems.
You are absolutely correct that, in the event there IS a button that holds the case in place, you absolutely should have it depressed, but the button in this picture looks like a power button or something similar, making your point irrelevant.

I tried editing this step, but it wouldn't let me. As Chris says, DON'T pry off the back housing. It will break your phone! Some of these are tricky, as mine doesn't always lift off easily regardless of whether or not I press the bottom button. At the most, with the button depressed, put something like a guitar pick or similar in the seam and use that to help you lift off the back, but make sure the button is pressed down!
