Hello.

If phone's baseband became unknown after writing of modem - this modem is not compatible with current firmware of the phone. You should write initial modem back into the phone, or write a complete firmware.

Unfortunately "Unlock" operation is not supported for SM-G925F on Android 7 firmware at the moment. To unlock the phone You can try to downgrade firmware version to Android 6.x (write complete firmware, not only modem).
