If you're like me, I ended up having a random piece fall out of the phone that I had no idea where it went. After searching I gave up and left it out. However, after looking at the second photo in this step, the one with it tilted fully towards the camera, I found it. Between the index and thumb in the photo, directly in the center of the phone is a thick gray bar. Just to the right of it is a loose piece that might fall out for you. It looks like two thin pieces of metal that sandwich some insulation. You will also notice two tiny tabs bent at an angle on each end only on one side. If that piece does fall out, that's where it goes. Just match the tab angles with this photo and location. I, unfortunately, don't have that piece anymore and am not willing to break through that display adhesive to put it back anyways.

I found what helped the best, was after grabbing the tab wrapping it around the tip of the spudger, and rolling slowly away, holding it as close as possible to where the tab was. Before I did that since you're pulling so much at once it easily snapped in half. Luckily I could grab a tiny bit of the strip. After wrapping it around the spudger, it no longer broke. The whole strip came off in one piece. Both pieces are complete horizontal pieces and are along the entire width of the battery, from the side you're pulling to the other side of the battery. There's quite a bit there especially since it stretches during this process. You'll feel it suddenly basically give away. ******

It is very much like the adhesive strips you use to hang items on the wall. When you're removing the hook, you pull at a low angle on that tab and it stretches until it comes off clean. Pull too high and you peel paint. A similar process here, keep it low and roll it slowly on the spudger. It will come away cleanly.

While this is an excellent guide, like the others here, I find the ending statement of "To reassemble your device, follow the above steps in reverse order." very much a throw you in the deep end type of scenario. Figuring out how to place the adhesives that come with the kit was very much a trial and error thing. They are not quite intuitive and I was unable to find any answers anywhere. In my first attempt, the two strips for the battery, are a mess. You never get a visual of how or where they are since you remove them by pulling tabs in Step 21.

Here's the deal with them. Two protective layers, a clear oversized layer on one side, and blue cut to the exact shape on the other. Both sides are sticky. Once you figure out the placement, apply the adhesives by peeling the clear protective layer first. Line it up and firmly press. When ready to adhere to the other side, the blue layer is removed by 2 tabs that are part of the layer. Pull 1 tab and carefully peel it away and it should come away in 1 or 2 pieces.
