"Getting Linux on a PS4 is something that has been one of the longstanding aims of developers as far as hacking the Sony console is concerned. Now, PS4 users who have a console with version 4.55 of the system’s software installed can also get their Linux action on with a newly updated Linux Loader payload now available.

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)"
