A couple of details: 1. The connector is removed in a direction perpendicular to the plane of the board. I found that the gentle application of a knife blade on the side away from the wires, followed by moving the blade away from the board, will do the trick. 2. The adhesive is a 1/4” strip around the edges of the battery. There is no adhesive elsewhere.

Eric, thanks for the guide to replacing the LG K10 screen. I was about to commit to doing one, but when I went to buy a part, the first thing I found was the glass cover over the display, which of course is way cheaper than the whole display. Can you comment about changing out just the glass?
