Listen on all interfaces

Use Cydia/Sileo with htps://build.frida.re (as above) and install Frida.

Find the /Library/LaunchDaemons/re.frida.server.plist file and modify it.

SSH into the iDevice.

sshpass -p "alpine" ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null root@<iDevice_ip>

apt-get install nano -y
cd /private/preboot/.../jb-.../procursus/Library/LaunchDaemons/
# or
cd /Library/LaunchDaemons

# e.g.
# /private/preboot/49AEB187534EBCF67D94F20A9A0C51FAE7683C2B57992616CC5E2C20884A8B3D42FBC080D4CE71F7BB2777AFD6D3D14C/jb-Tzx1Ga1D/procursus/Library/LaunchDaemons/re.frida.server.plist

  • Test the frida remote connection

frida-ps -H <iDevice_ip>
frida-ps -H <iDevice_ip> -ai
