Lost IMEI on G920A, Android 6.0.1

I have SM-G920A from US, AT&T. I suppose, it has been unlocked before re-selling. Was working fine in Europe (Lithuania) on a local network for two months. But after no visible impact (no physical damage, no flashing etc) it has lost IMEI and networking. My guess - it happened after an automatic update. Is there any chance to regain IMEI? (no back-up was made before)
I have checked the IMEI on various sites - it seems to be not blocked, clean.
Right now I have such information:
Firmware's CSC Code: ATT
Bootloader Version: G920AUCS4CPG1
PDA Version: G920AUCS4CPG1
CSC Version: G920AUCS4CPG1
Baseband Version: [empty]
Android version: 6.0.1
Build Number: MMB29K.G920AUCS4CPG1
IMEI: [empty]
Android Serial Number: 03157df3d063aa03
Samsung serial number: R38G30Q4CBA
I would very appreciate your help, guys! Could it help to re-instal G920AUCS4CPG1 via Odin? Any other solutions?

Do you mean to restore backup? Would it be easy, but no backup has been made before with SmartSwitch.

Go to about phone/software/service provider and look for the 3 csc code eg XEU/XEU/XEU.
The middle should be the active csc, the last csc is where the phone is from.
But since you are on a OXM firmware you can flash any OXM (N950FOXM5....) firmware and use "home-CSC" file to keep data.
