Thanks for providing this guide, I would have been lost without it. My old kindle, however, had very stiff and hard rubber/plastic. There was no way I could have slid the glass to the side or gotten the plastic spud under the edge of the glass or the plastic.

What I did was to remove a piece of the plastic next to the glass , about 1/8” square, then insert a putty knife in between the two sides towards the edges. It all popped apart without breaking anything. Perhaps I could have done this without cutting out the little piece.
