Problem description
iPhone XR will boot up normally but freeze and restart when pincode is entered

Symptoms
- Phone boots fine
- Type in your pin code & at the last digit, it freezes, keeping that digit highlighted for about 30-60 seconds
- Then the screen restarts and you're back at the pin code screen.
Solution
- Check NFC (U_NFC_S) above CPU
- It most likely has a hairline crack & requires to be replaced.
- Once replaced, the phone will go through a "swipe to recover" screen in most cases, where you put in the pin code, it loads a white "Attempting Data Recovery" screen & takes about 10-20 minutes.
- This is basically the operating system rewriting the NFC chip, so it can unlock.
- Then, the phone will work fine afterwards
