If you have a template and a really fine exacto knife maybe.
But it's better to buy the adhesive or use B-7000 or something similar.

It takes a little time to learn how to do certain things. As always a video tutorial is better than the picture only version. But if you follow one of their teardowns maybe you can get an idea of how to do some of the more intricate things like the battery adhesive removal. I do this as a hobby and it took a while to perfect, but my first 2 repairs went well and I didn't brick my phone or my iPad so guess I was doing some of the basics right.

Don't be discouraged. Watch some YT vids. Then work up the courage to try again. Good Luck!

Are you guys ever going to finish the teardown? Lol

It's been a year already and nothing.
