A new update has been released for PS5-Server , the software originally developed by Stooged and recently revived by 0x1iii1ii , which allows us to use the ESP microcontroller to create a local Wi-Fi server.

This server allows you to run exploits on the PlayStation 5 kernel running firmware versions between 3.xx and 5.xx, such as LightningMods ‘ fork of idlesauce with etaHEN .

PS5-Server simply redirects HTTPS requests (e.g. User Guide) to an internal HTTP page, while UMTX2 Exploit Offline Host offers a similar but optimized method for more ESP devices.

The latest update adds support for etaHEN 2.2B , removes the component libhijacker-game-patchfrom the ESP32-S2 and ESP32 devices due to limited flash memory, and adds a new toggled payload for kstuff.

Supported Devices

ESP8266 : For example, D1 Mini PRO (160MHz CPU required for PS5-Server).
ESP32 / ESP32 Dongle .
ESP32-S2 / ESP32-S2 Dongle .
ESP32-S3 / LILYGO T-Dongle-S3 .

Note : The ESP device must have 4 MB or more flash memory .

Installation and use

Here are the steps to setup and use PS5 UMTX2 Exploit Offline Host (or PS5-Server, with some variations):

Necessary materials

A supported ESP device (ESP8266, ESP32, ESP32-S2, ESP32-S3).
Computer for firmware flashing.
PS5 with firmware 3.xx or 4.xx.
USB cable to connect the ESP to the computer.

Steps

Download the firmware for your ESP device .

Flash the file .binto the ESP

Download and install NodeMCU PyFlasher (available for Windows, macOS, Linux).
- Connect the ESP device to your computer via USB.
- Open NodeMCU PyFlasher:
- Select the ESP COM port.
- Please upload the correct file .bin.
- Check the “Wipe all data” option .
- Leave the other settings as default.
- Click “Flash” to upload the firmware.

Connect to the ESP Wi-Fi network

Turn on the ESP device after flashing.
On PS5, go to Settings > Network > Set Up Internet Connection > Use Wi-Fi .

Find the network created by the ESP

SSID : PS5_ESP_HOST(for ESP8266) or PS5_ESP32_HOST(for ESP32/ESP32-Sx).
Password : 12345678.

Launch the exploit

Option 1 : Use the package esphost_media.pkg. Load and install it on your PS5 via USB, then boot it.
Option 2 : Open a browser on your PS5 (or a device connected to the ESP network) and go to 10.1.1.1.
Option 3 : Go to Settings > User Guide, Health & Security on your PS5. The prompt will redirect to the exploit page.
The exploit (UMTX2 or etaHEN) should load automatically.

Result

If everything works as expected, you will see a message or interface confirming that the exploit was executed.

PS5 Server (ESP8266 D1 Mini PRO) Specific Notes

Set the CPU frequency to 160 MHz if you are using Arduino IDE to upload custom firmware.
It may require a .ino code instead of a .bin , depending on the version.

Changelog

Updated etaHEN to version 2.2B.
Removed libhijacker-game-patch from ESP32-S2 and ESP32 due to low flash memory available.
Added toggle payload for kstuff.

Only supports PS5 with firmware version 1.XX to 5.XX
