Bunch of bullshit what you are stating Ashraf. By law Autel has to register the device to the new owner to his email and discard the old owner's info. Unless you are making the customer sign a vivid agreement that it must not be resold you will still end up in courts to explain, Why ! ?
It will not take long for few people to file a class action lawsuit against Autel for its illegal violation of customers rights. Do the thing that a lot of people bought a used Autel device but are stuck with not able to register with their email. No one , from the previous owners will give their passwords and no one likes to. Go figure with the help of a lawyer what you are doing is a serious violation of the law. I have seen too many complaints in shops and online about Autel. Also the fact that Autel is selling mx808 and mk808 as different models but exact same hardware and softwares. Autel is resorting to fraud to achieve sales. This is USA not Pakistan or India. Be advised.
