In January, the PS4 crack based on the 4.05 firmware was released. On February 28th, the 4.55 firmware’s PS4 soft break was also announced. PS5 crack based on 5.05 firmware is also officially implemented. The 5.0 system (code name: NOBUNAGA) was deployed by Sony in late 2017, and 5.05 was released in mid-January. Currently, the latest firmware version of the PS4 is 5.55, updated on May 17.

Similar to the cracking process, the most recommended method is to modify the DNS to use the browser to load Henkaku. The main difficulty lies in the users of the following versions of 5.05 firmware, mainly 5.0x/4.7x how to successfully upgrade to 5.05.
The 5.05 kernel exploit stack is now released! It includes the kexploit and autolaunches homebrew patches and mira. On subsequent page loads it listens for payloads. Source is up here https://t.co/lUqveOs46A

“In this project you will find a full implementation of the second “bpf” kernel exploit for the PlayStation 4 on 5.05. It will allow you to run arbitrary code as kernel, to allow jailbreaking and kernel-level modifications to the system. This exploit also contains autolaunching code for Mira and Vortex’s HEN payload. Subsequent loads will launch the usual payload launcher.”
However, unfortunately, like the previous two versions, there is no cure, and every time you shut down or reboot you must run it again.
A few notes on the 5.05 exploit:
1) The page will crash after the kernel exploit successfully runs, this is normal
2) First load after successful exploitation will autoload HEN and Mira (can get klog by nc [ps4 ip] 9998
3) Subsequent loads go to the usual payload launcher.— Specter (@SpecterDev) May 27, 2018
