elahd Thanks dude. (I use online translator) Your instuction helped me. The reason for the breakdown was different. Under the NFC connector, near the battery, a sealing parallon has fallen. And modern NFC contact block stopped working. I cleaned the contact under the bolt (unscrewed from the board, back to the thread retainer) and restored the contact on the connector. NFC is working again. Other instructions on the Internet did not correspond to reality. Good luck.
