Injecting OrbisRPC into the PS4 — the complete guide

This exists because getting a payload to execute took longer than writing the payload. Everything below was learned on a real 9.00 console.

You need first

• PS4 on 9.00, jailbroken with GoldHEN (2.4b18+ recommended — older payloader builds segfault on ELF files, see below).
• Console and computer on the same network. Find the PS4 IP: Settings → Network → View Connection Status (ours is 192.168.1.136).
• The payload file: build-sdk/orbisrpc_sdk.elf (built via ./scripts/build_sdk.sh).

Method 1 — elfldr (recommended)

elfldr is a proper ELF loader that runs payloads as separate processes.

1. Get it listening. Either load elfldr.elf through GoldHEN's payloader page once, or keep it running — it serves on port 9021 until reboot.
2. Send the payload with a raw TCP connection, then close the write side:

import socket
data = open("build-sdk/orbisrpc_sdk.elf", "rb").read()
s = socket.socket()
s.settimeout(25)
s.connect(("192.168.1.136", 9021))
s.sendall(data)
try:
    s.shutdown(socket.SHUT_WR)  # signals end-of-payload
except OSError:
    pass
s.close()

3. Verify it runs: within ~20 seconds /data/orbisRPC/log.txt must contain orbisRPC payload boot. No file = it never executed.

Method 2 — GoldHEN BinLoader server (port 9020)

The classic route (NetCat tools, phone apps, scripts all speak it).

1. Arm it: tap BinLoader in the exploit host menu (NOT the GoldHEN settings payloader page — different loader).
2. Within seconds, fire blind — one single connection carrying the full payload, no port check first:

import socket
data = open("build-sdk/orbisrpc_sdk.elf", "rb").read()
s = socket.socket()
s.settimeout(25)
s.connect(("192.168.1.136", 9020))
s.sendall(data)
s.close()

3. Same verification: look for orbisRPC payload boot in the log.

THE ONE-SHOT RULE (read this twice)

GoldHEN's BinLoader arms once. Any empty port check (connect_ex, nc -z, port scanners) connects with nothing to send and burns the arm — the real payload then arrives at a dead listener. Sequence is always: tap → say go → fire immediately → verify. Never probe first.

Method 3 — sender page (no PC tools)

https://SirHumza.github.io/orbisrpc-host/ in the PS4 browser auto-sends the bundled backend to the console's own loader and prints the result on screen.

What NOT to use

• GoldHEN settings payloader page: on GoldHEN ≤ 2.4 (pre-b18.5 lineage) its loader thread segfaults (SIGSEGV, null read in GoldHENLoader) on every ELF — including 90KB hello-worlds. The klog prints payload launched successfully and then dies. If you see this, update GoldHEN, don't rebuild the payload.
• Raw SELF files: the page expects ELF (\x7fELF). SELF uploads report "invalid payload".

Troubleshooting

Symptom	Meaning	Fix
Connection refused on 9021/9020	No listener armed	Tap BinLoader / open payloader page, retry instantly
payload launched successfully then silence, no log	Loader segfault (see above)	Update GoldHEN ≥ v2.4b18.5, use BinLoader server
Error handling payload	Loader rejected the bytes	Re-check file integrity (shasum), resend
Log exists but FATAL: token rejected (4004)	Token rotated/dead	Fresh token into /data/orbisRPC/config.json, relaunch
Multiple Payload processes in process list	Old instances piled up	Reboot clears them; the daemon's lock prevents recurrence

Watching it work

• Kernel log (loader events, faults): TCP 192.168.1.136:3232, raw stream.
• Daemon log: /data/orbisRPC/log.txt via FTP (192.168.1.136:2121, anonymous). Absent file = payload never executed, full stop.
• Process list: sysctl kern.proc (see scripts/ps4_watch.py) — look for Payload and eboot.bin entries.
• Final proof: Discord profile shows the game + ticking timer.
