unlock prblem error(0) g928g

please help. I do not know which modem to install compatible for that version and that does not give me that error

1. Power on the phone.
2. Connect the phone to PC with USB cable.
3. Check Samsung modem in device manager, install drivers if needed.
4. Press ‘Unlock’ button for direct unlock or ‘Read codes’ to read security codes.

To reset Google account activation or Samsung reactivation lock:
1. ADB must be activated in any way (you can flash sBoot from combination firmware,
make sure, that you are not upgrade sBoot).
2. Connect phone to PC with USB cable, install drivers if needed.
3. Select device in ADB settings.
4. Press ‘Reset FRP/React/EE’ to deactivate Google/Samsung/EE account activation lock.
(Sometimes needs to perform ‘wipe data/factory reset’ once more, to complete this locks removal.)
