Hi, experts!
When you try to update the firmware from 3.3.0 to 4.1.0, a warning occurs. Do I understand correctly: if you continue to this update, a) the configuration will be reset to the default, and b) it will be impossible to return the old firmware. If during this update the configuration is reset to default, is it possible to restore it from the backup made in firmware 3.3.0?
Thanks You!
