That standoff is critical to the proper functioning of the NFC functions. It is connected directly to the NFC bracket (see this guide, Steps 41 & 42) and then to the rest of the circuitry. If it has been removed cleanly, then it can be re-soldered into place. The risk is if it caused logic board trace damage, which would have to be repaired in addition to it being secured back into place.
This will require a micro-soldering repair.

You could try to secure it in place with some glue and then run a jumper to get NFC connectivity.
But do you think that the microscopic connections are opened ? If I need a fix, can you do it ?
Hello Artur. My apologies but I had never noticed the update you provided with your answer. I don't get a notification because you set it up s an answer instead of a comment on mine.
At any rate, I agree, it doesn't look like there are any traces below that standoff and I checked with ZXW and there are no maps of traces either (although that doesn't mean there aren't any). That standoff, which connects to the NFC bracket has to be connected to a few adjacent components. If you do micro-soldering yourself, it should be straight-forward. If you don't, then check out my profile to get in contact with me directly.
Thanks for your good answer
I believe that the traces are ok, only the dark brown layer got off, but I have no continuity from BS2504 to the component linked to it, so, the NFC function needs stockholm antenna ?

Hello again, a guy from England solder me the screw hole again, but he said that BS2502 has long screw damage, and he said that is not repairable but I saw on youtube very ugly long screw damage with a hole on the PCB, but in my case don't... I think he don't want to spend time repairing that.... The PCB also miss 2 backlight filter that I can provide to you if you want because I already have bought them in the past. Can you give a check for me ?
