My experience pt2
Fortunately the shattering was mostly on the edges and most of it had adhesive on the back so it stuck together. Just take your time and work your way around following the guide to get the screen off. Have some goof off or goo be gone to clean the frame when putting the new glass on or putting the existing one back. (someone suggested that also, very good idea). Be careful of the LCD (you should know that). The cable on my LCD was pretty tight, so I propped it up while taking the cable cover off and when I put it back on I did the same thing. I just put a bottle on the battery and leaned the back of the LCD on that while attaching the cables and putting the screws back on the cover. Also be careful with the home button and the bracket on the back of it. I had enough old adhesive on left on the bracket that it stuck back to the new glass fine. So far only 12 hours in, so we will see how that holds up when the kids get at it.
My experience. I was replacing the screen which had been cracked and a little shattered in some places. The iopener is pretty much useless, so was the suction cup. The suction cup would probably be more useful if I was doing something besides the screen. Also you probably want the clean the screen before using it so it can get good suction. I used a hair dryer on high for a couple of minutes at a time (someone on this tread suggested that). I used my exacto knife and a razor blade to get into the adhesive. First the exacto to get the initial cut, then the razor blade to go a little deeper. Could have probably just used the razor blade, but the exacto has a little more finesse. I got the razor blade in and a little under the glass then I used the picks to wedge in. I didn’t want to risk anything using the razor blade too much. Used tape to keep the shattered glass together.
