No IMEI and network after flashing EFS

Hi,

I broke my Galaxy S8 plus G955FD two weeks ago and bought another one exactly the same.
I have a nandroid backup from the former phone I decided to flash into the new one.
I guess my mistake was to flash the EFS too.
Now both IMEI (double SIM) show unknown and no network connection. Everything else work just fine.
I need help to fix this.

Thanks
