yes sir that is correct.  A hard head makes a soft ass, I like that one, never heard that before but from now on I am going to honor your father  by saying it a lot, it makes all the sense in the world to me. I know autel must have a very soft ass cuz they don't listen man. take care buddy. 

 Hi your issues have nothing to do with software but rather hardware. there has to be something wrong with your vci interface, try re-flashing your vci and make sure it goes thru the process again. autel support  can also help you reset it to its original software. what ever the case maybe no vehicle update will fix your issues, this updates are only related to missing functions or disable functions, not communication problems. good luck. contact your tool provider and have them replace your vci if none of this tips help you.
