I bought a brand new Nexus 5. I downloaded all the necessary files as instructed for the Linux Root Toolkit and followed the instructions exactly. I reflashed back to stock, then installed Supersu and TWRP. Then I flashed CM13 in TWRP. When I go to install Nethunter at this point, the Aroma installer always freezes. I wait a bit and restart my phone and it always gets stuck on the boot screen no matter how long I wait. I'm following everything correctly so I have no idea what the problem could be.
