Hi Sithum,

You can check Offensive Security list for your device compatibility with your Net Hunter:
https://www.offensive-security.com/kali-linux-nethunter-download/
Or
https://gitlab.com/kalilinux/nethunter/

Please note that not only the above devices are compatible with Net Hunter, though you can try it and see. In addition, Zaid is going to unpublish the course because it is out of date, he already requested that from Udemy so they will unpublish it in the next few days. I’m sorry about that, he might completely remake the course with the newest version of Net Hunter this year, he will keep you posted through the notifications.
