I did this a little different and it really simplified things for me and virtually eliminates any mistakes as long as you’re careful. Don’t put the back cover on until you’ve verified that everything is working. The back is just to keep dust and dirt out. So turn the phone on and make sure every thing is working before you put the cover back on.

To put the cover back on, I left the plastic on both sides of the adhesive. Place it on the back of the phone using the camera cover as a guide. The little notch on the induction coil verifies right side up. Check the edges for proper alignment. Once confident with the alignment, Remove the exposed plastic. It should be clear, the blue comes off later. Line the back cover with the camera, and push it onto the adhesive. Press into place, then removed the back cover. Adhesive is now on back cover with out any stretching, misalignment, wrinkles or bubbles. Remove the blue plastic and place back onto the phone, starting at the camera. Snapping in the edges.

If you go slow, and keep you fingers as close to the phone as possible, it comes off easily. Don’t just work a corner loose and keep pulling from there. If you do the more you get pulled loose, the more it can stretch. Pull up a quarter inch or so an slide your fingers down and do it again. When you done the plastic won’t be stretched and it still has enough sticky to reuse it.

Absolutely true. Mine popped off and shot across the room. I was lucky to be able to find it.

After you heat the Iopener, lay the shiny side on the phone. With all the warnings of how hot it could get, I handled it with oven mitts. It wasn’t until I struggled for some time trying to get the back of that I grabbed the Iopener with my bare hand and found the the shiny side was still hot, but the textured side was quite cool. Apparently it has some insulating properties.
