I want to have Kali Nethunter on my device as well as a 7.1.1 custom rom but i don't want to multiboot a 6.0.1 rom with Nethunter and a 7.1.1 custom rom. I noticed this page had Nougat for the Nexus 5 so i'm assuming its possible to use Nethunter with 7.1.1 but i have no idea how to build it. All i really want to achieve is a custom rom like Nitrogen with Nethunter on top, is that at all possible ?
