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

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

It's a new and improved ftp bin it might be desired by some here.

I'd need the link to the github so I can compile it.

I think that's the one you posted earlier. Need both the PS4's IP as well as your PCs.

I Believe it does hmmm I can and find link hang on

"To quote from the README.md file: DumpFile405

File Decrypter for the PS4 version 4.05

Change your ip address to use the pc you are listening ie:
Code:
socat - tcp-listen:9023

send the payload like:
Code:
socat -u FILEumpFile405.bin TCP:<ps4 ip>:9020

Compile with IDC's Cturt *** mod ps4-payload-*** https://github.com/VV1LD/DumpFile405

Does PSProxy work with 4.05, or has it been patched ?

I mean I'm happy there is now/soon a jailbreak for 4.05, but it would be very inconvenient if I cant access PSN for future games, or any game that requires the latest firmware.

I'm currently on 3.55 by the way.
