If you own a PS4 on firmware 4.55 or below, rejoice! Developer [ Register or Signin to view external links. ] has released a fully functional implementation of [ Register or Signin to view external links. ] for the PS4. This is technically what you can consider as a full functional Jailbreak for PS4 4.55, but the payloads (the binaries that let you actually do cool stuff with your PS4 such as running homebrew or unlocking debug settings) still have to be ported to this firmware.

In this project you will find a full implementation of the "bpf" kernel exploit for the PlayStation 4 on 4.55. It will allow you to run arbitrary code as kernel, to allow jailbreaking and kernel-level modifications to the system. This release however, does not contain any code related to defeating anti-piracy mechanisms or running homebrew. This exploit does include a loader that listens for payloads on port 9020 and will execute them upon receival.
