So to procure your own "developer" license, you need to go to this link, and either register for a Samsung account or sign into your own, and then enroll as a developer.
After that proceed to this link and generate a Knox Standard SDK Enterprise license key with a generic "key alias" (I recommend something like "testing", not something like "adhell", just in case).
Copy over the key to your device somehow (email, Join, Pushbullet, etc.) as it is pretty long.
When you open up the new Adhell 2 app, you will see a popup asking you to enable device admin access, enter a key, and then enable license, do the three steps in that order. If the key is not entered correctly, the license will not activate.
