It would have been better to highlight the comment about the two rubber grommets “that wrap around the threaded posts at the very bottom of the phone front panel. . .” in re-assembly instructions, rather than being buried in the comments. I had to re-open the case to switch the grommets from the old screen to the new.
The step that took the most time was the attachment of the digitizer cable connector. Finally I felt a small click on one end, and then the other. Whew! Thanks for the clear instructions!
