For the record: It is not actually a good idea to make a habit of
curl $(random_script_from_the_internets) | bash"
Always read the source of what you run before you run it.

Your interfaces are now displayed for you to replace INTERFACE in step 5 with your ethernet interface of choice.

Run pppwn

For 9.00

pppwn --interface INTERFACE --fw 900 --stage1 "/etc/PPPwnWRT/stage1.bin" --stage2 "/etc/PPPwnWRT/stage2.bin" --auto-retry

For 11.00

pppwn --interface INTERFACE --fw 1100 --stage1 "/etc/PPPwnWRT/stage1.bin" --stage2 "/etc/PPPwnWRT/stage2.bin" --auto-retry

On your PS4:

Go to Settings and then Network
Select Set Up Internet connection and choose Use a LAN Cable
Choose Custom setup and choose PPPoE for IP Address Settings
Enter anything for PPPoE User ID and PPPoE Password
Choose Automatic for DNS Settings and MTU Settings
Choose Do Not Use for Proxy Server
Choose Test Internet Connection

So there isn't the overhead of this running all the time you need to do step's 5/6 every time you want to root your PS4, you don't need to do the internet connection set up again just test the internet connection. The custom version of stage2 first looks for the payload in the root directory of the USB drive, and if found, it is copied to the internal HDD at this path: /data/GoldHEN/payloads/goldhen.bin. The internal payload is then loaded and is no longer needed on the external USB drive. You can remove the usb drive from your ps4 after it has been run the first time and you won't need it again.

To root your console again you can SSH in and run pppwn again or install the luci web interface for customs commands with

opkg install luci-app-commands

In the web interface you can add the pppwn command under System>Custom Commands and run it from there, you just won't be able to see the live output.

WPS Button Exploit Trigger

Install kmod-button-hotplug
opkg install kmod-button-hotplug
Create a file called wps in /etc/hotplug.d/button/ with the contents below.

source /lib/functions.sh
 
do_button () {
    local button
    local action
    local handler
    local min
    local max
 
    config_get button "${1}" button
    config_get action "${1}" action
    config_get handler "${1}" handler
    config_get min "${1}" min
    config_get max "${1}" max
 
    [ "${ACTION}" = "${action}" -a "${BUTTON}" = "${button}" -a -n "${handler}" ] && {
        [ -z "${min}" -o -z "${max}" ] && eval ${handler}
        [ -n "${min}" -a -n "${max}" ] && {
            [ "${min}" -le "${SEEN}" -a "${max}" -ge "${SEEN}" ] && eval ${handler}
        }
    }
}
 
config_load system
config_foreach do_button button
EOF
 
uci add system button
uci set system.@button[-1].button="wps"
uci set system.@button[-1].action="released"
uci set system.@button[-1].handler="pppwn --interface INTERFACE --fw 900 --stage1 "/etc/PPPwnWRT/stage1.bin" --stage2 "/etc/PPPwnWRT/stage2.bin" --auto-retry"
uci set system.@button[-1].min="0"
uci set system.@button[-1].max="2"
uci add system button
uci set system.@button[-1].button="wps"
uci set system.@button[-1].action="released"
uci set system.@button[-1].handler="/etc/rc.button/wps"
uci set system.@button[-1].min="3"
uci set system.@button[-1].max="10"
uci commit system

Be sure to put the proper interface/FW in the handler line.

This will trigger pppwn to run when pressed for less then 2 seconds and when pressed for 3-10 seconds will trigger the stock wps functionality.
Triggering your LED to turn on and off during the PL is specific to your router which is why it was left out of this config.
Further resources with LED examples can be found here https://openwrt.org/docs/guide-user/hardware/hardware.button

Kill Script

Comes with a kill script in /root that used Modded Warfare's kill script as a template, but was modified to work with this setup. The original script used this resource as a template.

Dedicated Device

If you would like to make this a dedicated device you can If you can make it a daemon with an init script https://openwrt.org/docs/techref/initscripts
or run it at startup by running for 9.00

sed -i '3 i\pppwn --interface INTERFACE --fw 900 --stage1 "/etc/PPPwnWRT/stage1.bin" --stage2 "/etc/PPPwnWRT/stage2.bin" --auto-retry' /etc/rc.local

for 11.00

sed -i '3 i\pppwn --interface INTERFACE --fw 1100 --stage1 "/etc/PPPwnWRT/stage1.bin" --stage2 "/etc/PPPwnWRT/stage2.bin" --auto-retry' /etc/rc.local

Manual Install

git clone sistro's pppwn repo and build pppwn S1 and S2 PL's for your FW https://github.com/SiSTR0/PPPwn
Put the S1 and S2 PL's in a dir name PPPwnWRT and scp or sftp the dir to /etc
git clone and build pppwn_cpp or pull from their nightly build server
Repo: https://github.com/xfangfang/PPPwn_cpp
Nightly build server: https://nightly.link/xfangfang/PPPwn_cpp/workflows/ci.yaml/main?status=completed
scp or sftp the executable to /bin
Install libpcap1
Run pppwn

DD-WRT Install

DD-WRT uses a different package manager and pcap package, so the OpenWRT install script above will not work for DD-WRT.

Follow the manual install method to step 4
Install libpcap ipkg install libpcap
Run pppwn

Daasin / PPPwnWRT
