Octoplus Samsung Software v4.2.5 Release Notes:
Added Factory Reset FRP via Online Service.
Added an additional method to Unlock MDM via ADB (works for devices where #0# menu is present). You will have the choice to use the QR code or ADB.
The ADB method should be used in case you have problems with the QR code, for example, if the device does not scan the QR code, Knox 1, etc.
