PS4 Linux on 4.05 is a Thing! Valentinbreiz / Darbnes #Hello2018

Finally it's happening... over a year ago fail0verflow revealed PS4 Linux on 4.05 Firmware and continued to school the PlayStation 4 scene on everything from Adieu to Kernel Dumping which ignited the 4.05 era of exploiting, jailbreaking and once again PS4 Linux followed by PS4 Linux Loader 4.55!

Many may recall seeing a demonstration from the Tencent Security Conference, and according to Rebug developer @Joonie early PS4 Linux Loader work was missing the now released 4.05 Kernel Exploit.

While many developers including @jocover have been working (405_linux_loader.bin - 21 KB) on a PS4 Linux Loader (GIT), PlayStation 4 developer @valentinbreiz (Twitter) who brought us the 4.05 PS4 Payload Sender last week was able to get PS4 Linux running on 4.05 with PS4-Linux-Loader.bin payload testing by @Darbness (Twitter) who shared a 4.05 PS4 Linux demo video below!

Download: PS4-Linux-Loader-master.zip / ps4linux.rar (7.0 MB) / ps4linux.rar (Mirror) / PS4-Linux-Loader.bin (1.0 MB) / PS4Linux_Fedora.zip by fail0veflow (2.27 GB - Build Pass is 1 via @MrCarlesX) / GIT / Live Demo / PS4 Linux on Slim 4.05 Firmware by ecHs / PS4 Linux Loader 4.55

From the README.md, to quote: PS4 Linux Loader - A simple payload that lets you run Linux on your 4.05 PS4

WORKS! With IDC's exploit.

Hosted here for your use: http://darbness.com/ps4.

How to build

I use https://github.com/idc/ps4-payload-*** to compile it. You also need to compile https://github.com/fail0verflow/ps4-kexec and place 'kexec.bin' into this folder. Compile kexec with 'make CFLAG='-DPS4_4_05 -DKASLR -DNO_SYMTAB'.

How to use

You need a FAT32 formatted USB drive plugged in on any PS4's USB port with the following files on the root directory : bzImage and initramfs.cpio.gz. You can download them here.

Then you will need to send the payload (PS4-Linux-Loader.bin) to your PS4. For that go to your PS4 web browser, go to darbness.com/ps4 and send the payload to your PS4 using netcat or other.. (You can also use my tool: PS4 Payload Sender).

To do:

• Fix ASLR (that causes a random successful boot)
• Clean code

I reread anything, but I dont understand what do you mean with compile kexic, can you copy paste me pls what you mean?

Look in the above post for the story and carefully read the first section title "how to build" somehow you missed this section entirely sir.

I recently took a look at ModdedWarfare's guide on how to install Linux on PS4.

My question is although he mentioned there are no graphic drivers and stuff to speed up Linux gaming, how is it f0f managed to run dolphin emulator on Linux? Did they use graphics drivers? Or is it not necessary?

@SSShowmik they used vulkan i am trying to do this right now

 

[SSShowmik]

Please do tell us if you succeed, and if you have please tell us all how to do so

 

[seanp2500]

this is part of my work to gift my mugen game to the scene on ps4...it will all be told on my channel...

kexec.bin and PS4_Linux_Loader.bin are already in valentinbreiz's git. Do we still need to compile them ourselves or can we just use those ones?

 

[seanp2500]

I honestly don't see what's stopping anyone from hosting one but all I see at his git is the instructions on how to compile which makes sense. Remember you are basically editing a kexic to boot on ps4.

There is a method to use just one usb see here:

Also if using two sticks slight correct kexic.bin should go on the linux install usb. Sorry to confuse anyone. I would usually add it to both and didn't realize one clearly works.

Do you mean with compile kexec host the own exploit?

Hi.
Can I use a ps4 (ofw 4.05) as Linux PC? I know it's possible, but how much is usable? Can I install it permanently on a partition of internal HDD? Driver of CPU and GPU are full and stable (AMD official drivers will work?)
