well the maxisys does not backup vehicle information since this feature will use too much of its internal storage. what you do is connect your tool to a laptop thru the mini usb cable provided. copy the entire content of the tool to your pc assuming this is your first backup. then as they release new updates just copy the vehicles from the vehicle folders. path = scan/vehicle/ then the specific vehicle region folder/ then the specific vehicle make folder/ vehicle. get familiar doing this procedure as it will need to be done frequently after every update.

Hi ede65,
 
I hope that everyone can feel your return.

Thanks.

If you go to the amazon app store through the amazon apk, there is an app called "dumpster". It is the andriod version of a trash bin, except it has a little more capabilities. It can save anything you delete or replace, and you can restore and replace new versions with old ones. I recommend it.

 I DOWNLOAD  DUMPSTER FROM AMAZON  AND  TEST IT BY DELETING UNUSED CAR APPS AND THEY DINT SHOW UP IN DUMPSTER. SO THEY WERE LOST. I WONDER WHAT IF I DO SOMETHING  WRONG
