Jailbreak Kernel Patches

Features

  • Jailbreak
  • Sandbox escape
  • Debug settings
  • Enable UART
  • Disable system update messages
  • Delete system updates
  • Fake self support
  • Fake pkg support
  • RPC server
  • RPC client in C#

I use the standard fake pkg keys, created by flatz.

General Notes

Only for 4.55 Jailbroken PlayStation 4 consoles!

The main jkpatch payload utilizes a port of CTurt's payload sdk. Change the Makefile to have LIBPS4 point to the ps4-payload-sdk directory on your machine. I could have it referenced from the home directory but meh...

# change this to point to your ps4-payload-sdk directory
LIBPS4	:=	/home/John/ps4-payload-sdk/libPS4

If you decide to edit the resolve code in the kernel payload, make sure you do not mess with...

void resolve(uint64_t kernbase);

... as it is called from crt0.s. And changing this will produce errors.

See other branches for other kernel support. I will support latest publically exploited firmware on main branch.

RPC Quickstart

See either Example.cs or look at the RPC documentation.

You can read/write memory, call functions, read/write kernel memory, and even load elfs.

Here is a cool example of an elf loaded into COD Ghosts (forge mod made by me!) You can download the source code to the forge mod here. Have fun!

Coming Soon

  • General code clean up and refactoring

Thank you to flatz, idc, zecoxao, hitodama, osdev.org, and anyone else I forgot!
