Just replaced a screen on a series 3 LTE. I used a donor screen from a locked Series 3 LTE. Everything went off without a hitch. However, I can confirm Apple pay does not work. I get an error when attempting to set it up. I have not yet attempted to swap the NFC chip. I will attempt to see if I can remove the NFC chip tomorrow from the cracked screen and install... If anyone has any further information about this I would be happy to hear it...
