After teasing the exploit recently on Discord, SpecterDev has officially released his kernel exploit for PS4 firmware version 4.05.

Official announcement

Hope everyone had a Merry Christmas! Here's the 4.05 kernel exploit, fully implemented. Enjoy! Write-up coming soon! https://t.co/MQR0lzCu9Y

— Specter (@SpecterDev) December 27, 2017

Code:
https://github.com/Cryptogenic/PS4-4.05-Kernel-Exploit

TLDNR (From GitHub):

In this project you will find a full implementation of the "namedobj" kernel exploit for the PlayStation 4 on 4.05. 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 9020 and will execute them upon receival.

In case you want to get a PS4 <=4.05

UPDATE:

after @SpecterDev released his exploit, i'll prepare stuff within a couple of days, someone need to backport it from 4.55 to 4.05, not hard to do. not sure if it will be a write-up or just snippets of code, let's see

i have 4.07 i can't do nothing for now?

No. That's what it said 4.05. Since Sony patched exploit on 4.06 and closed it so nothing you can do about it but wait.

There is a 4.50/4.55 kernel exploit so just hang in there.

 

[DinohScene]

Neato!

Hopefully this will drive the rest to create some awesome projects much like the PS3 had!

 

[nikeymikey]

I have a ps3 and I was banned from psn because of cfw, so don't expect anything safe soon

It will be perfectly safe if you stay offline

Maybe somebody asked this question before but, can we update hacked ps4 to latest firmware (still hacked) like ps3 rebug, etc.?

No

 

[TR_mahmutpek]

No

What? Rly? How? We can do that on ps3, and we have the ps4 kernel exploit.

 

[FreePlayFlorida]

patience, and reading is key here, yes it sucks its only a specific firmware at present, maybe give it time and can hope others will follow, and a little reading, heck even rereading articles to answer your own questions helps a lot, would love to see progress for other firmwares, play backups etc, but just have to wait and time will tell what wonders will happen, the skills of some people is amazing, and what they can create

We can do that on the ps3 because the hacked firmware for it is 4.82.

there s no boost mode in 4.05? isnt it?
so o guess useless to buy a pro in that case

 

[Bimmel]

Wow, the number of posts here is sad. Where is the joy?

 

[nikeymikey]

That’s not correct because it was doable well before 4.82 was hacked....

 

[TR_mahmutpek]

Welp, I am retreating now..

4.06 (the firmware in which the exploit was patched) came out in November 2016. They're gonna come with 4.07, like the Horizon Zero Dawn bundles.

I make a big mistake and deleted my psn profile (i didn't want it associated with hacks and had no plans to go on psn with my jailbroken ps4). This made things harder for me as I did not realize this would break web browser. In hindsight this was a good thing. This is experience other user will have with new ps4 out the box. I hope this helps others....
