iPhone 6 Screen
Well I got about 1/2 way back through the re-assembly and found that the digitizer cable was too short. I disassembled back to here and this time started snapping the new display surface back into place beginning at the end where the digitizer cable feeds through. Then I did a "dry-run" with the logic board to ensure the cable reaches and it looks good.
This screw was very hard to replace - lost the part after many minutes of trying.
