Tried to get the screen propped up to start loosening the adhesive. I tried using both the provided iOpener and an SMD rework heat gun, set at very low settings (100 - 120C). Even with extensive heat, I could not get the screen to budge. It’s quite hard to get leverage to lift the screen off, and with the amount of force I was trying to pull on the suction cup to get the screen up, I was concerned about breaking the screen.
I should have read the many reviews by people saying that they broke the screen, so that’s on me, but honestly cannot recommend this. I don’t really think iFixit should be offering this as a product to be honest.
