iPhone 13 mini iPhone 13 mini NFC Failure

[illuddin_PowerPC]

NFC is no longer working on my iPhone 13 mini (iOS18.2).
The trigger was when the exterior of the iPhone was replaced and repaired.
All the parts were removed to replace the exterior.
During the removal process, I destroyed them,

Magsafe & Power Button Module
Flash module
GPS module

which were destroyed in the process of removal.
After that, we reassembled the device and checked its operation. All other functions were fine, but only the NFC module was malfunctioning.
The symptom is that there is no response when reading IC cards, etc., in this screen state.
We are using another iPhone to check if the card originally responds to NFC.
I am having trouble understanding why the malfunction occurred.
I don't remember damaging the logic board severely, so I am even more unsure.
Please let me know if you have any clues that might help.
By the way, when I asked the AliExpress seller what to do, he told me to replace the Bluetooth antenna, which I did, but nothing resolved the symptoms.

I also performed a software restore, but that did not improve the symptoms.

Far too many variables mentioned given you’ve transplanted all the components and possibly damaged them in doing so.

It would be almost impossible to give you any meaningful information given your device has been extensively repaired.

Yes, it is.
However, if we exclude the possibility that the damage is to the logic board, which components are most often affected?
We are also considering the possibility of connector defects.
