PS4 4.55 “Holy Grail” PS4Hen released, enables pkg support (homebrew & “backups”)
What is Holy Grail for PS4 4.55
When run in combination with the recently released exploit for PS4 4.55, Holy Grail lets users install and run unsigned packages. In practice, this will let 4.55 owners install and run homebrews as well as, yes, pirated PS4 games.

In other words, Holy Grail is the equivalent of PS4Hen that was released on Firmware 4.05.
A few developers have confirmed after this release that 4.05 homebrews work “as is” on firmware 4.55. Some users have reported that they feel Holy Grail is not as stable as PS4Hen on PS4 4.05, with some reporting some crashes or having to try the payload a couple times, although no major issue. The Video below from user Andrew2007 demonstrates Homebrew “Controller Tester” running on the console.
Other Payloads & exploit updates
In parallel, in the past few hours, multiple updates and releases have happened since a fully functional PS4 4.55 exploit was published earlier today. Besides the holy grail payload, payloads for enabling the web browser (without signing in to PSN) and for enabling Debug Settings have been released. Use at your own risk for now, until the dust settles on these very fresh releases.
The exploit itself has been updated by SpecterDev to fix some bugs and patch dlsym, a step that was critical to ensure 4.05 Payloads could be easier to port to the 4.55 exploit. This matters mostly for you if you’ve been trying to use the 4.55 payloads and ran into issues: make sure you are using the latest version of the exploit, which at the time of writing was uploaded less than 6h ago.
Al Azif has updated his ps4-exploit-host to version 0.4.0 to support the 4.55 exploits. If you plan to use it, ensure you download the latest version of the exploit from SpecterDev’s github, and replace the one in ps4-exploit-host with the one from SpecterDev, to ensure you have the latest version.
