PS4 Linux on 4.05 Firmware

[RealCFW]

Hello CC,

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! :beer::beer:

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

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
