    • Take something thin, such as a knife, and wedge it between the screen and the body of the phone

    • One you have created some space, wedge your plastic opening tool into the space and remove the knife

    • Move your plastic opening tool up and down the side of the phone while lightly pulling up. Repeat this for all sides until the screen comes out

    • If you wish to preserve the LCD screen, be careful how deep you wedge the plastic opening tool in and how hard you pull up to get the screen out. Depending on the depth of the plastic opening tool and strength used, there is a high risk of damaging the LCD screen

    • Remove the old adhesive from the body and replace with new adhesive so the new screen will stay in place

  13. Before reassembly, be sure to transfer the front speaker grille if it is not included with the new screen. If not, carefully push the grille out from the old screen, then reinsert it on the new LCD.

Did you get it working i have the same issue? the picture displays with the original screen but not with the new one. i have tried 3 different screens and get the same on all of them. i even tried updating to the latest software but only get a black screen, no picture.

When i have had this on iphones i just so a reset by holding down the buttons and the screen starts to work.

Please someone help

Same here! I also findout that lcd still works, if you get some flashlight on screen in a dark room, you will see that only backlight not working when battery plugged. I tried to baking it but it still didn't worked. It's obvious that backlight could properly operate as it works when you take off the battery. I'm looking for solutions, if I find any, will wrote it here.

Did someone find a solution to this? I also replaced my screen and it keeps black solid when I turn it on, even with the touch working properly.
