yes you can if you backed up prev versions. search the forum for more info

  hondaman  i have  older versions saved  on my computer.   i did a search  and cant find  nothing on it.     can you explane   how to do it.       right now i have gm 7.30          on my maxisys mini.     and 5.10 gm saved  on my computer.      do i just  add the 5.10 folder  in the  vehicle  folder.    and  then will i also have  the icon for 5.10.  and still  have the 7.30 icon

 you are correct. Rename Gm version 5.10 to GM5.10 so it had a different file name from current GM version. Then drop old version into folder Scan/vehicle/usa folder. Autel will recognize it as a new program and will allow you to run prev version. Version 5.10 still had the old logo so no change is needed. Reboot your tablet and you should see two versions of gm. Good luck
