This step was a little bit confusing. I thought that the entire ribbon assm should be removed once the speaker was detached. The entire assm doesn’t actually come off until Step 30.
One thing I don’t see mentioned is the replacement of the rubber gaskets that are on the pentalobe holes. The replacement screen did not come with these on it. I was able to remove them from the OEM screen, but there was no easy way to get them to adhere to the new screen. If they move just a little, you might not be able to properly thread the pentalobe screws. Worst case is that they fall into the body of the phone during this last step of re-assembly. At that point, you’ve already started to have the screen stuck to the adhesive, so you would need to redo the entire adhesive gasket.
