EORaptor & MicroRaptor · PS4

Installation & Usage Guide

Everything you need to wire the board to any PS4 model, power it safely inside or outside the console, and run every operation from the EORaptor PC & mobile apps.

PS4 FAT · Slim · Pro Windows & Android Beginner-friendly
Using MicroRaptor? Great — this guide applies to both boards. MicroRaptor runs the same apps and the same flashing steps; just use the pinout printed on your board.

1 Board sections

The board is designed to be simple, organized, and small so you can read the pinout quickly and connect it to the console easily.

EORaptor board overview

The board has 4 main sections:

  • SFlash: WP#, SO, GND, SI, HOLD#, CLK, VCC
  • Syscon: TOOL0, RESET, GND, VDD, EVDD
  • UART: RX
  • Power handler (for inside-console installs): VinVout
Note: you do not need to connect all four sections — connect only what you need. For full control we recommend at least SFlash and Syscon.

2 Before you start

Have these ready before you open the console:

🧰

Your board

EORaptor or MicroRaptor, with the wires for the sections you’ll use.

🔌

USB-C cable

To power the board when working outside the console.

🖥️

PC or phone

Windows 10+ or Android 8+ to run the control app.

🛠️

Soldering tools

Fine-tip iron, flux and thin wire for clean joints.

Golden rule: use one power source only. Never power from USB and the PS4 PSU at the same time — it can damage the board.

4 Syscon support & Auto Unlock

The board supports all PS4 Syscon chips except the 94xxxx family.

Important: if your console has the 94xxxx Syscon, you can’t use the board with it.

The board uses Auto Unlock for Syscon. In every diagram you’ll see a pin named VDD. On the first installation you must leave VDD off-board (not connected) so the board can do the unlock. After unlock, the app tells you to solder it back.

PS4 Pro only: in Pro diagrams you’ll see two VDD pins for Syscon glitching. Leave both off-board the first time. Follow the diagram / video.
Check for shorts: make sure the VDD pin you left off-board is not shorted to the pin next to it. A short makes the app keep “trying to unlock” with no result and can damage the board.

5 Installing inside the console (PSU)

When installing the board inside a PS4, cut the PSU power line and pass it through Vin → Vout on the board. Follow the picture that matches your console:

Board placement examples

Use these as a reference for where to put the board inside the console:

Note: do not use a USB cable to power the board if you already connected Vin and Vout to the PS4 PSU.

6 Powering the board

After all wires are connected, you have two ways to power the board:

  • Outside the console: power using USB Type-C.
  • Inside the console (Vin/Vout connected): just plug the PS4 power cable.
Do not plug the PS4 power cable while powering from USB. Use one power source only, or you can damage the board.

If everything is correct, the board’s Power LED will be red. Now you’re ready to use the app.

7 The app — first connection

The app is available for Windows and Android. If you haven’t installed it yet, grab it from the downloads section.

  1. Language: switch the app language.
  2. Info: show information about the app.
  3. Connection type: choose Wi-Fi (preferred) or USB (slower).
  4. Connect: when ready, press Connect to start.
Wi-Fi note: from your phone or PC, first connect to the board’s Wi-Fi. The network always starts with EORaptor-xxxxxx.

8 Main screen

  1. Language: change UI language.
  2. Info: information / about.
  3. Flash Mode: cuts power from PSU to motherboard so the board can work without interruptions — very useful when installed inside the console. When Flash Mode is ON you cannot power on the console. To power the console, toggle Flash Mode OFF. Do not run operations while Flash Mode is OFF.
  4. Available modes: SFlash · Syscon · UART · Backup/Restore · Multiboot.

9 First time: unlock Syscon

The first time you connect to a console, unlock Syscon. Open the Syscon page and click Read.

After success: the app asks you to solder VDD back. After that you don’t need to connect VDD again for this console.

10 Wiring checks & errors

The board always tests your wires before doing an operation.

  • Failed to switch to Syscon → a problem on the Syscon side. Re-check Syscon wires.
  • Failed to switch SFlash / Unknown Manufacturer ID / Unknown Chip ID → a problem on the SFlash wires.

11 Backup & Restore

Always make a full backup of the console first. The board makes it easy:

  1. Click Backup.
  2. Choose a folder where the backup will be saved.
  3. Done.
Note: you can save many backups of the same console — or other consoles — in the same folder. On restore, the app automatically detects which backups belong to this console.

To restore, click Restore and choose the folder with your backups. The app shows the date/time and FW version for each one.

12 SFlash

To read SFlash: click Read → choose where to save → choose a file name.

To write SFlash back: click Write → select the file to write.

Safety: the board checks the console serial number against the serial inside the file. If they don’t match, it warns that the file doesn’t belong to this console — preventing bricks.

13 Syscon page

Click Read to get a full reading of your PS4 Syscon and save it. Click Write to write Syscon back.

14 Multiboot

Multiboot is one of the best features. Make a full backup of your current firmware and later restore it in under 4 minutes. Example:

  • Console on 5.05 → backup
  • Update to 9.00 → backup
  • Update to 13.00 → backup

Now from Multiboot you can pick any backed-up FW and restore it quickly — go up or down any time.

  1. Status of current FW: shows current FW version and active slot.
  2. Quick backup: backs up the current FW. If already saved, it shows “Already backed up”.
  3. Firmware Library: all FWs available to restore. Each offers Restore · View details · Delete · Cancel.

15 UART

UART on the board is very fast. Instead of a full manual SFlash read/patch/write, it can do it in under 20 seconds so you can read UART quickly.

Note: make sure you connected RX and GND to the console so you can read UART.

When you open the UART page for the first time, the app asks if you want to enable UART. Choose Yes and enable all flags.

After that click Start, then turn on the console — you’ll see the UART logs.

Important: UART is the only mode where you power on the console while using the board. If you’re powering from USB, do not plug the PS4 power cable until you click Start and the app says it switched to UART mode.
