I skipped steps 6-9 and held the screen in one hand and removed the screws for the battery and the battery itself with the other. I did the whole process in about 5mins. Back up and running and at 100% charge. My wife's iPhone 5 is back and working. Hopefully the new battery solves the 50% to 10% instantaneous drops that her original battery was seeing after being in service for about 12 months.
