Is this real? If it is how would he do this?

There's this guy on TikTok named Dr. Auto and he is able to jailbreak Teslas and get features such as premium connectivity, full self driving, free, supercharging, and more. Here is one of his videos. How do y'all think he did this? Are there any posts on the Internet talking about this?
