Developers ValentinBreiz and Vultra are the two to thank for the updated payload, with their hard work now making it possible for PS4 software version 4.55 to also be corralled into running Linux.
Similarly to the release of the payload relating to version 4.05, this updated 4.55 release is still only available for the original “fat” PS4, although some of the PS4 slim consoles are compatible with the release – be sure to check that your particular model number is listed as one that works before trying to get Linux installed.
That list currently includes:
Using a PS4 Slim with a different model number? You’re unfortunately currently out of luck, although ValendinBreiz does say that this is being worked on, with an aim to get others online soon.
Full information on how to get Linux running on your PS4 can be found on the developer’s GitHub presence, along with the installation instructions:
You need a FAT32 formatted USB drive plugged in any PS4’s USB port with the following files on the root directory: bzImage and initramfs.cpio.gz….
Then you will need to send the payload (PS4-Linux-Loader.bin) to your PS4. For that go to your PS4 web browser, send the payload to your PS4 using netcat or other.. (You can alse use my tool: PS4 Payload Sender).
