Here are instructions to install Nethunter (as a ROM) with working native monitor mode in the chroot using Nexmon. The ROM is a modified CM 14.1 (nougat) base with custom kernel which supports: HID, Drivedroid, Kexec, and external wireless.
You will need the following 3 items (maybe 4):

Have you flashed Cyanogenmod before? If you can flash CM or a ROM its exactly the same way.
There is the easy way:using the Nexus Root Toolkit
There is the harder way:
- Download ADB and fastboot (depends on OS/distro)
- Put phone into fastboot by holding down vol down + power
- Warning this will wipe device In terminal on computer: fastboot oem unlock && fastboot reboot
- Reboot back into fastboot
- In terminal on computer: fastboot flash recovery TWRP_multirom_hammerhead_20160210.img
- Now boot into recovery by either using menu in fastboot or holding volume up + power.
If you have made into recovery you will want to copy the NethunterOS zip file to your device and maybe also the radio zip file.
- Always make a backup of a working OS under the backup tab. Select system/data/boot
- Wipe any previous ROMs by going to wipe tab. Select Advanced Wipe & system/data/cache
- Finaly go to install button and select NethunterOS zip file.
Reboot your device. When it starts up the first time it will reboot once, don't be nervours.
After your device loads go through the normal CM set up. Copy the kalifs-full.tar.xz from your computer to your device. Then:
- Go to the Nethunter app
- Go to "Kali Chroot Manger" after accepting permissions. If previous Chroot was found click "Remove Chroot" first.
- Click on "Install Chroot" > Use SDCARD > Use Full
- Exit out of app and run Nethunter terminal app and launch into Kali terminal
There is a specific binary file for loading mointior mode inside chroot. To run it inside Kali terminal:
source monstart-nh
To stop run:
source monstop-nh
Since we are using LD_PRELOAD the monitor mode is essentialy tied to the terminal window. So if you open a new window make sure you rerun script.
The technical explanation is we need to set LD_PRELOAD to our ioctl intercept that was compiled inside chroot. When the chroot is run we have to unset LD_PRELOAD and we are essentially telling the terminal to run LD_PRELOAD before each command.
It's a simple bash script and you can view it in /system/xbin/monstart-nh
If new versions come out you can flash ROM without having to go through most of the early steps. You can just go straight into recovery and install the zip file over ROM.
Here are things that need to be done for Nethunter OS:
- Add extra apks to Nethunter OS (drivedroid etc)
- Add a native updater
- Fix wallpaper offset

I finally got my hands on a nexus 5. Trying to get monitor mode working with the internal wireless controller so I can use wifite.
I flashed lineage-14.1-20190126-nightly-hammerhead-signed.zip, Magisk-v31.0-legacy.zip, and kali-nethunter-2026.2-hammerhead-los-nougat-full.zip
Unfortunately, when I run ifconfig wlan0 up I get the error SIOCSIFFLAGS: Operation not permitted
I tried installing nexmon from fdroid and installing the packages it provides. But after clicking enable monitor mode it caused my device to bootloop.
I did a dirty flash to get it back up an running. I then learned about the hammerheadmon.zip which is no longer hosted on lineageOS servers.
I found the google drive link above and flashed the 1st_zip_to_flash_-_kernel-nethunter-hammerheadmon-nougat-2019.03-13-0514.zip I downloaded from there.
Unfortunately I still can't get monitor mode working. Am I missing something?
