Dropped and cracked
went OK. Was tough to get the logic board completely reinstalled correct; sim card tray was too tight in the end, and ended up slightly bent. However, it worked.
The instructions hint at only taking the large head philips screws out 1.5 turns and that will save some in the reinstall. That was not obvious and I missed that instruction while going through it. instead of windex'ing every metal to metal connection, i washed my hands every half hour and tried to minimize touching - I used tweezers a lot. ALSO: before screwing down the logic board, make sure the antenna connector near the speaker assembly is not under it. It would be great if you actually reversed the instructions vs just saying go backwards.
