Sleirsgoevy Announces PS5 Kstuff Porting Tool Complete for Missing Offsets

In PS5Scene news today developer @sleirsgoevy announced on Twitter that the Kstuff PS5 Porting Tool is complete allowing others to dump the offsets for the missing PlayStation 5 Firmware on PS5 versions 3.00 to 4.51 that have a kernel exploit while noting the list of currently supported revisions (3.00, 3.10, 3.20, 3.21, 4.00, 4.02 added thus far to 4.03, 4.50 and 4.51) can be found in offsets.c on his Github repository.

This comes proceeding the PS5 Kernel Exploit 4.03 / 4.50 / 4.51 Firmware Version Updates, PS5 Kernel Exploit v1.01 for 4.03 / 4.50 / 4.51, PS5 Kernel Exploit Payload.bin Loader Host, 4.03 PS5 HEN PS4 FPKG Enabler Payload, 4.50 PS5 HEN PS4 FPKG Enabler Payload and 4.51 PS5 HEN PS4 FPKG Enabler Payload with a PS5 Kstuff Porting Tool Guide to dump the offsets of Firmware not yet supported via the README.md:

Instructions for PS5-kstuff porting_tool (original by NotSoTypicalGamer and EchoStretch)

1. Make sure PS5 is jailbroken and running your exploit of choice with the ELF loader active
2. Use Linux, this README is focused on Ubuntu specifically (WSL2 doesnt appear to work)
3. Clone this repository locally:
   1. git clone https://github.com/sleirsgoevy/ps4jb-payloads.git --recursive --recurse-submodules -b bd-jb
   2. move into the right folder cd ps4jb-payloads/ps5-kstuff/porting_tool
4. Create symbols.json in the same folder and the contents should be:

   {"allproc": <ALLPROC_OFFSET>}

   1. to find the ALLPROC_OFFSET for your firmware, search on Specter's GitHub
   2. the offsets are located here document/en/ps5/offsets, find the right .js file for your firmware and search for OFFSET_KERNEL_DATA_BASE_ALLPROC. The HEX value you will find needs to be converted to DEC (just use a website online)
   3. you can finally substitute <ALLPROC_OFFSET> with the DEC value you got and save the file
5. Make sure python3 is installed
6. Install gdb-tools either with pip install gdb-tools or sudo apt-get install gdb if the other command doesn't work.
7. Install yasm with sudo apt install yasm
8. Try and run the script with

   python3 main.py symbols.json <your.ps5.ip.address> <elf.loader.port> kernel-data.bin

9. Once complete you should have kernel-data.bin dumped into porting_tool folder.
10. symbols.json will have also been updated to include needed information.

NOTE: This tool isn't complete. This doesn't grab all the data necessary to port "ps5-kstuff" to other firmwares. It's a WIP.

Finally, Sleirsgoevy states, "You can verify the found offsets by running the script test_offsets.py with the same arguments. It should launch a ps5-kstuff that can run fPKG files. If that works, please submit your JSON file either here, or to the testing channel on PS5 R&D Discord."

On 3.10 and patiently waiting but have a strong hunch to update to 4.03

@PSXHAX Thank you for the reply. Yeah I am in the end user category for the homebrew. I already have another console that I use to play games that I want to always play online.

I was also more wondering if anyone thinks there would be something better that would be for lower firmware because of usually more unpatched exploits or is nothing going to be better then what would come out for 4.03.

It seems (and i probably missed something) that right now there are way more tools and things created for 4.03 then any lower firmware.

Love seeing the progress made recently. Thankfully kept my system on 3.21 all this time being patient, even with the 4.xx stuff coming out and now I can finally use my launch PS5 after all this time. Can't wait for backports to work so I can finally play FFXVI which was the whole reason I bought the system.

Tip of the hat to Sleirsgoevy, what a reverse engineer!

My ps5 on 3.20 keeps having kernel panic.. have already factory reset 4 times.. any solution?

 

[Aksielle]

I recently upgraded to version 4.03, it's a shame

 

[Vivaan Patel]

Always clearing browser cookies and website data in settings before running jailbreak is being stability to jailbreak process.. also not having frequent kernel panic

The ps5 scene is booming right now!

Does anyone advise upgrading to version 4.03 or 4.51 from 3.20? The goal is to play games exclusively. Is there a possibility of a new jailbreak or a full PS5 jailbreak with flatz's PSP? Or should I stick with version 3.20, as I have been using it for the past two years?
