Great guide! I was able to remove the battery without the use of the adhesive remover, just using a nylon fishing line to cut the adhesive. Note that the disassembly requires T8 and T9 bits which were not in the kit I got from iFixit.
My 3.9mm upper left screw (green) is T8 Torx, while the upper right 3.8mm (blue) screw is a T9 Torx. Note that both are not included in the kit sold by iFixit for this repair @jeffsu
