In my personal opinion, this guide have a bunch of steps that aren’t necessary. I just replaced a cracked one. And I just removed the battery for security purposes since I was going to use heat. But you don’t have to remove the mother board or anything else, just disconnect the digitizer flex and then start prying on front. That’s it.

Is that black tape important? I wasn’t lucky and it was torn.

How do you calibrate the digitizer afterwards?

Step 11 talks about using a Phillips 000 drill bit, rather than screwdriver, to remove the screws.
