Developer DeathRGH has just released a new update to Frame4 , an advanced extension of the ps4debug library , designed to offer advanced debugging and manipulation tools on jailbroken PlayStation 4 consoles .

The software is compatible with several firmware versions, including 5.05, 6.72, 9.00 and 11.00, and enables technical operations such as analyzing loaded modules, accessing detailed console information (including PSID, firmware and SDK), managing active processes and scanning memory through AOB (Array of Bytes) patterns.

Frame4 also allows you to hook into crash traps (fatal hooks) and backtraces, making it useful for studying errors and malfunctions.

It also supports coredump management, patches for compatible firmware, and allows access to physical and kernel memory, including virtual maps.

Functionality

Process list .
List of modules .
Virtual memory map (both kernel and user space).
Read/Write memory (both kernel and user space).
Read/Write physical memory (in kernel context).
Debugger (for userspace).
Function Call (RPC) .
UART server on port 3321 .
HTTP server on port 2812 .
Setting the fan threshold temperature .
Console information (PSID, SDK/UPD version, kernel info, etc.).
System notifications .
Loading ELF files .
Loading SPRX modules .
(and more).

Patch

Disable ASLR.
Mounts /useron any process.
Disable coredump creation.
Removes firmware checks for PKG files (note: param.sfothey elf/prxstill need backporting).
Removed asynchronous I/O spam (blkno) on firmware 5.05.
Patch for kernel panic caused by 2MB pages (firmware 9.00 and above).
Patch for loading ELF files into the kernel ( "vm_fault_copy_wired: page missing").
Patch to VirtualQueryallow use of sceKernelVirtualQueryon pages marked as system.
(and more).

Syscall

Frame4 installs the following custom syscalls:

107 sys_proc_list
108 sys_proc_rw
109 sys_proc_cmd
110 sys_kern_base
111 sys_kern_rw
112 sys_console_cmd
115 sys_kern_cmd

Supported PS4 Firmware

5.05
6.72
7.02
9.00
11.00 (Note: Support for 11.00 is just being tested; any feedback is helpful!)
If you are on 6.72 or 7.02, we recommend upgrading to 9.00!

Compatible libraries

C#
C++ (in progress)
JavaScript

Goals

Allow Frame4 to be loaded along with ps4debug. Done!!
Replace the syscalls (107-112) used for the commands, to avoid conflicts with ps4debug.
Abandon multiple compilations and unify everything (as Dizz already did for ps5debug).
Implement SPRX loading without depending on GoldHEN.
Fix scanner on console.
Avoid ShellCore hijacking and create your own process.
Move all functionality that does not require kernel access to user space.

Hook for fatal traps

Adds detailed information about fatal traps and initiates a clean reboot. Example:

Fatal trap 12: page fault while in kernel mode

# registers:
#    rdi 0x880AE1DE0
#    rsi 0xFFFFFFFFADBB0000
#    rdx 0x1000

#    r8  0xFFFFFFFFD7049740

Hook for backtrace

Add details to crash logs, avoiding manual module offset calculation. Example:

...
#
# backtrace:
# 0x0000000000BB7BF1 </data/default_mp.elf> + 0x7B7BF1
# 0x0000000000B924EA </data/default_mp.elf> + 0x7924EA
# 0x00000000009D75A4 </data/default_mp.elf> + 0x5D75A4
# 0x000000000083BE99 </data/default_mp.elf> + 0x43BE99
# 0x00000008000075C2 </i8fsuSWSEf/common/lib/libkernel.sprx> + 0x75C2
# 0x0000000000000000
#

Changelog

List of modules.
Extended information about the console (including PSID, SDK, firmware version, …).
Extended process management for resuming, stopping and terminating.
Basic AOB scan.
Hook for fatal traps.
Hook for backtrace.
Patch for coredump on all firmwares (prevents blue screen when a game crashes).
Patch for sys_virtual_query(allows querying pages marked as system).
Kernel virtual memory map.
Reading physical memory in kernel context.

Note: AFR has been removed in this update due to issues with the way it was implemented (it wrote to the top of the kernel base). It may be reinstated in the future; for now it is recommended to use the GH plugin .
