Are there any statistics or even educated guesses about how many people are able to successfully complete this repair? Although it is rated as “moderate” in terms of difficulty, I would rate it as more than just moderate. I tried to replace the battery on a much older iPhone and wound up with a brick. Is an 8 plus easier than an iPhone 3 or 4? Where might one find such statistics?

#6 would not reattach. I spent an hour trying to reattach that ONE thing. I finally had to give up. What a complete waste of time.
