Safe to restore Autel ms908s maxisys to factory settings?

Question: is it safe to restore a Genuine Autel maxisys ms908s back to factory settings?


So to follow up if you reset to factory you need to buy an update from Autel because the app won’t work. There is no vehicles!
However if you backup your ‘scan’ folder to a 32GB usb drive before the reset (takes about 6hours) then you copy it back after the reset. The app will then contact the Autel server to activate without buying update and will work as before.
