I logged into my own email by starting to use etc + restart + power (it will also delete your chromebook data be aware) then doing ctrl d, and after it says its blocked go back and when you enable the internet and it says enterprice enrollment , disable your internet and then in the bottom left it will say “use as personal chromebook” press that and it will ask for your internet, after enabling it will go to the sign in page with the enrollment, instead press other sign in, and enter your own mail. After that it will enroll it in that mail and your set to go in your own mail.
