SpecterDev on PS4 4.05 Jailbreak: Release could happen this week
Developer SpecterDev has been hard at work to implement the recently disclosed PS4 Kernel Exploit for firmware 4.05. Screenshots surfaced on Reddit’s PS4Homebrew discord channel, mentioning that SpecterDev could be releasing his work as early as today or tomorrow (Update: SpecterDev has confirmed to me in a separate conversation that this is indeed the current status).
Two months ago, Team Fail0verflow disclosed technical details of a kernel exploit for the PS4, running up to firmware 4.05. At the time, I believed it would be a matter of days for a full implementation to be released to the scene. It turns out some difficult components of the implementation have been left blank by the Fail0verflow writeup, and the few hackers who have tried to implement a full Jailbreak have ran into issues.
This was the case of SpecterDev, who stated yesterday that games “freeze on boot” after running the hack, in his implementation of the Jailbreak. He’s mentioned that issue almost a month ago already, so it’s unclear if that part will be fixed by release time. This could sound as a “deal breaker” for many, but SpecterDev confirmed that payloads can be run (this includes Linux as far as I understand).
“WebKit exit seems to be stabilized in the exploit chain, however launching games will freeze on boot. But at least payloads can be ran with system stability now with games aside :)”
I’m convinced that if the Jailbreak is released and open sourced, more eyes will be looking into it and could help fix whatever issues SpecterDev has been running into.
