Replacing iphone 3G Digitizer

Hey guys, i need some urgent help from you all guys. I have a iPhone 3G which is now 2 years old. It was working fine but suddenly its screen got damaged by falling on the floor. I have seen some people changing the Digitizer by themself. So better than paying for that i'll decided to try it myself.

Do you guys have any idea of doing that ? If yes, please let me know too, soon. Step by step process will be appreciated. Thanks in advance.

We start by removing the two screws next to the dock connector. I preferred to use a plunger to break the screen housing. So I do not risk damaging the edges of the casing with a metal tool.

It disconnects the three layers. The screen is separated from the box. Attention screws used to fasten the LCD to the plastic frame are all small. The iFixit guide explains very well how to separate the LCD touch screen and plastic frame.

After separating the LCD frame, the more difficult sometimes. We must take off the touch screen of the plastic frame.The glue is quite strong and present throughout the frame.

The touch screen is broken, we can leverage by sliding a metal object between it and the plastic frame. Do not use excessive force because the plastic frame is not thick. Do not bend it.

After half an hour the touch screen is separated from the plastic frame. You remove the remaining glue on the plastic frame in order to paste the new touch screen. Once the glue dries, you proceed with reassembling the screen by following the guide in reverse. Thats it

I used a multi-purpose glue for all materials that can reposition the objects for 5 min. I did not take the risk of using an adhesive glue 10 sec, the time is too short to properly place the glass on the plastic frame. I applied the glue all around the plastic frame, identical to the previous glue. The drying time is one hour, I put the glass pressed against the plastic frame with four pegs.

Thanks for sharing the useful tip, mates. But everybody remember that this repair is at your own risk. No one be held responsible for damages or problems caused to your phone. The repair is not easy, do not worry if you do not feel to do so. Anyway I hope I never have the opportunity to use this tutorial.

If you have the spare to the process is very simple as all you have to remove a few screws and replace the damaged part. With the replacement B, without being too difficult, things a bit more complicated, because we have to use a heat gun or hair dryer to remove the glass + digitizer frame that includes the Home button. YOu will need some tools for the process like Ventosa, Phillips Screwdriver and spatula or plastic screwdriver.

"If what you want to change is the only scanner, you'll need the heat gun and dale carefully heat, once you have completely disassembled the equipment.

Be careful not to break the lcd, the digitizer is stuck so you have to give separate heat and slowly. When you get to separate the the lcd housing (previous step) I recommend you use a small plunger to prevent scratching the screen."

Its really a great discussion, i found here. Perhaps one of the main drawbacks of the large iPhone screen glass is that if you fall a certain height is usually broken into pieces. The repair, if sent to the technical officer, usually exceed 200 euros. However, if you bought the screen on our own this tutorial can make it in about 50 Euro. With that price difference many of us prefer to buy the parts and do the replacement ourself.
