Thanks for this excellent guide! I succeeded in changing the battery in my phone. This was my first time opening up a phone so I’m even more pleased that it went so well. For the tools, I used things that I had on hand (suction cup from a bathroom hook, regular tweezers, thin cut up plastic card to make picks, hair dryer) and they all did the job. However the “picks” I used were not sturdy enough, which made it harder to cut the adhesive. If I did this again I would cut up a thicker card, or just buy some picks.
