Found a donor iPhone X I could purchase to repair my X with cracked front and back glass. Have learned it's not as simple as swapping / plugging in the new parts. Face ID, TrueTone, Taptic may not function without purchasing / using a screen programmer. Guess my options are to take it to someone who has the tool or purchase a programmer and do it myself. Have changed many other screens but none requiring programming to retain a fully functional phone. Could really use some advise, links, etc., to save myself from searching for hours on the best way to get this done. Tks!
