Followed the instructions and everything went ok. Removing the screen was very hard and I advise people doing it to take precautions with the glass as it will most likely spray all over. What I did what to cover the screen in transparent tape, so that the glass wouldn’t jump all over. I also wore gloves and protective eye gear.
I have the same problem
Had to try 4 times until I finally got it right, I would say that less than 80° works well for this step, just take your time and be patient with the screws
