Hi there,
So, I Got it…wacky chit but it restored and is working again and I was able to update it after reconnecting to Senscraft AI site.
same stuff applies,
go here 
https://seeed-studio.github.io/SenseCraft-Web-Toolkit/#/setup/process
connect and upload a face detection model, after it will al be restored , then go back to sensecraft AI and connect you’ll see it’s restored.
Success…
