PS4 4.55 Jailbreak: SpecterDev releases full implementation, payloads pending
If you own a PS4 on firmware 4.55 or below, rejoice! Developer SpecterDev has released a fully functional implementation of Qwertyoruiop’s 4.55 Kernel Exploit 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.
From the release Readme:
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
9020and will execute them upon receival.
This bug was discovered by qwertyoruiopz, and can be found hosted on his website here.
Interestingly, this release does not use the webkit exploit that was released yesterday as an entry point. Instead, SpecterDev states the hackers have used a different webkit exploit, that was patched by Sony in firmware 5.03.
SpecterDev credits Qwertyoriuop, Flatz, and anynomous for the release.
The Video below from user Andrew2007 shows the exploit in action:
Download and run PS4 4.55 Exploit
Important disclaimer: at the time of writing, payloads for the exploit have not been ported yet. In other words, although the exploit is fully functional, without the payloads you won’t be able to do much. If you’re too excited to wait, feel free to download and test the exploit following the instructions below, but most of you will prefer to wait until payloads such as PS4Hen are ported to this exploit, and user friendly tools such as ps4-exploit-host are updated for 4.55.
You can download the PS4 4.55 Exploit on SpecterDev’s github here. To run and host the exploit, you’ll want to use a tool such as ps4-exploit-host by Al-Azif. Please note that Al-Azif’s tool currently only contains the 4.05 exploit, so you will need to replace the contents of the “exploits” folder with the one for 4.55. Ps4-exploit-host has a detailed readme on how to run the exploits when you use that tool.
Alternatively, you can host the exploit yourself, or point your PS4’s browser to Qwertyoruiop’s hosted version at http://crack.bargains/455/.
In the space of 2 months we have seen 4.05 kexploit 4.55 kexploit and a 5.01-5.50 WebKit entry.. wow ps4 scene actually exploded!
Exploded? If you ask me this is just the beginning of an explosion— whether the explosion completes itself to the degree of HENkaku/TaiHEN/Ensō remains to be seen.
Look, I hope it explodes in full as much as anyone else does. All I’m saying is the current status of PS4 homebrew and development is very user unfriendly. I think when the degree of user friendliness HENkaku brought appears on the PS4, then we can say it’s truly exploded.
As for what we have now… All the effort by the PS4 homebrew scene has been exciting to watch and I’m thankful for all of it. Never did I expect a current generation console to be exploited so quickly. Proud to say I own an exploitable PS4 too. Fingers crossed that the Xbox One gets some love eventually… and when it does I hope it ends up being better than the Xbox 360 (which sadly only seems to have Dashlaunch and Aurora going for it).
What do you think, When will piracy be a real thing on 4.55 or even5. 0x?
are you russian or something
Cud you you please explain to me what exactly al this tearms like exploit, Kexploit, webkit entry
How coud some one crack 5.01 even before it is released.. Till date 4.73 is latest right??
?please help me i am new to this
I fisted your momma
My ps4 was 4.50 but I had to wait for it
i have a ps4 whit 4.07
can i upgarde ofw to 4.55?
Yes you can by usb flash drive.
Holly grail payload ported for 4.55, all good to update from 4.05 to 4.55!
I regret that I updated my Pro when I bought Uncharted The lost legacy.
Wanted to play it, turned out it doesn’t even save achievements correctly.
I did not expected that from Naughty Dogs.
And now I wait for the next jb.
But I figured there is nothing really interesting to play right now on the PS4 anyway.
Earliest game worth considering update is NiNoKuni2 but I have reservations after seeing some gameplay.
Nice! Seems keeping my PS4 on 4.50 was worth the wait.
And I am sitting here on 5.03, good exciting news anyways even though there is only a Entry point Usermode exploit at the moment upto 5.05 I’ll stay patient for 5.0x kernel mode release
I’m glad 4.55 is now busted open allows for more people to enjoy the homebrew stuff
Dangggg I thought this was the year of the switch why the ps4 getting all this love lol
does anyone have a link to the 4.55 firmware
i am on 4.06 how do i get to 4.55 ?
I am new to PS4 world, And I have a PS4 with 4.70 installed, Can I use this exploit to jailbreak it?
Reply would be really appreciated.
When I use the exploit I get the following error in the web browser:
Post Exception: TypeError: undefined is not a constructor (evaluating ‘new window.rop()’)
What’s this about?
I have ps4 ofw 4.55
The ps4 doesn’t recognize the upgrade I’m assuming since it’s at the same firmware level? Can anyone help?
with the upcommig jailbreak would i run pirated games !!
Is It 100% Free ?
