PS4 4.55 FIRMWARE JAILBREAK

Very exciting news for the PS4 owners who are on Firmware 4.55 and lower as Qwertyoruiop has released a kernel exploit and now a full implementation of the exploit is on Github thanks to SpecterDev.
The 4.55 Exploit doesn't contain code relating to anti-backups mechanisms or running homebrew so it is recommended to take @flatz advice and stay on 4.05 and not to update to 4.55 if you lack skills in porting payloads.

Patches Included

The following patches are made by default in the Kernel ROP chain:

1.Allow unprivileged users to call setuid(0) successfully. Works as a status check, doubles as a privilege escalation.
2.Custom system call #11 (kexec()) to execute arbitrary code in kernel mode
3.Disable kernel write protection
4.Syscall instruction allowed anywhere
5.Disable kernel protection

Debug Menu:


Debug Menu has been ported to 4.55 by @2much4u. Here is the link for the full Debug Settings

(WARNING DO NOT GO INTO IDU MODE)

Here is a Tutorial on how to setup the Full PS4 4.55 Jailbreak

The 4.55 exploit has a loader that listens for payloads on port 9020 and will execute them as soon as the PS4 receives them. The bug was found by Qwertyoruiopz and it can be found hosted on his website
