PS4 Kernel Exploit Released for 4.05 OFW

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

Official announcement


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.

I have good news and bad news. The good news is in I FINALLY figured out a way on 4.01-4.05 to remove the update. I had been trying for months. I hate the update nag. For me the way was installing/reinstalling the 4.05 through safemode and re initializing did finally delete the update and the update nag buuuut you will lose everything including profile so not sure if that is issue for you.

for crash band wow hey boss there is a thread with all the bundles you can still buy not too late. Would you believe mine almost auto update to 5.01 during my jailbreaking process and i had to jump to yank the power cord? cray cray...
 
What's the point.You can't go online and you can't pirate your games.The only real thing you can do with this is turn it into a Linux machine,but doing that means you forfeit all the new exclusives that require a higher firmware since you cant play backups on it yet.The only people I can see benefiting from this are the people who own more than 1 ps4 and want to beta test new homebrew.

At this point, yes people can't go online while homebrew. But at some point it'll just be like Vita I think, can have PSN at least partially works.

Mugen on ps4! Imagine a Dreamcast Emu? The possibilities are endless. Don't be a hater. See you later...

limited ftp access achieved...

update
insanity just a 1 hour later and the help of simple person on twitter I now have full ftp access...



Oh and I got pkg installs to work. Someone told me this is not working yet. That is not correct. PKG installs fine. The problem is you would need a license file to play the content. PKG must be on root of USB just like on 1.76.

Exciting times....

And those license files? Did you try installing some dumps of games from 1.76?
 
Insane you can simply install packages!!

But yes what about the license files? Is this similiar to the playstation 3?

How are they generated and is there a method for 1.76 to bypass them already?
 
i will be doing more research tonight, but apparently there are tools to decrypt games and several were released for 1.76. These games will work if ftp to correct directories on 1.76 and I assume this is true for 4.05...
 
sorta not really what i did to remove update nag was reinitialize which sadly deleted all my paid games (fufufufufu sony) little did I know I would so quickly gain this access....ish happens

Congrats 4.05 users!
Next stop is 4.50/4.55 and then 5.01
My PS4's been waiting on 4.73 for some time, and when (if) the exploit for 5.01 releases I'll update via .PUP

sadly I have hit a dead end. I cannot use the elf loader via nodejs. PS4 throws a message "data not supported by PS4" i imagine it needs to be recompiled for the newer firmware similar to the webbrowser fix...
