It show that you need to update to active your iPhone. You can try to update the lastest iOS system to see. But you said restore iOS 12, you mean is you have update to iOS 12.0.1 and downgrade to iOS 12, Is it?

please connect the phone to your PC, and check whether it is work? If yes, the problem will be in the phone signal part. If not, there is carrier unlock, then check whether replace the motherboard, if it replaced, then re-proof the address of wifi and Bluetooth
