How to restore config from USB flash drive for Cisco sg250

[MinistrBob]

As a result of incorrect configuration, I lost access to it through the web interface. To reset to factory settings it is a pity because already much that has been made. Can I restore the configuration from the USB flash drive? And how to do it?
