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

thanks this might be helpful for me as i'm stuck in idu loop now.

DONT BE STUPID LIKE ME AND TURN ON IDU if so you will have to use staff mode code and it's very dodgy running exploit so far I can't get debug to open but I think it's payload or memory issue

The moment Specter said not to mess with some of the Debug settings I decided not to fiddle with them. Some of them are persistent as you're aware.

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

Sure, but the same method is used since the first 4.xx hacks. Prior to that we were stuck on 3.55, before that 3.41 and originally 3.15.

This ps4 hack is similar to the original psjailbreak, if you upgrade then you lose it.

well idu i guess is persistent on 1.76 users have reported resolving it so I am hopeful I can get it sorted but I am at work now...

We were not stuck on anything on PS3, you just needed 3.55 to be able to run the hack after that you could update to any of the CFW's available, hell, we can even downgrade back to 3.55 if we want. 3,41 was only support by the jailbreak dongle if i remember right.....

You are correct. I had 3.41 with dongle before. Awesome memories.

Once FTP connection will be possible on 4.05 , it's gonna rain games dump.
I guess that games decryption by Zecoxao also works on games>1.76

Yeah, can't wait. Since I have PS4 FW is 2.57

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

It's up to 5.03. SW needs kexploits, so if SW still works, there's an exploit.

What means this scene release?
"Firmware.v4.05.PS4.iNTERNAL-PS4FW"

I cannot find any nfo file...

Just a dump of v4.05 OFW I guess. Too bad boost mode was added in 4.50.

internal scene group no? That's interesting they did that....

Well its strange cause we can find all fw for ps4 in many online repository...

Well, not everyone can read or use the search properly.

 

[Zero72463]

Guy don't go updating yet until all the good stuff is ported to 4.05.

 

[qaz015393]

Nice I'm on 4.06 and cant wait for it.

 

[Deleted User]

YAY guys I was able to get out of IDU loop so please don't do what I did but if you do I have a fix for you. The web exploit will not work. It just won't. Something about IDU and 4.05 not enough memory. I had to host locally using python and that worked like a charm! Vid incoming!

People really thinking about "backups"? Good lord, have fun downloading 50gb+ worth of data per game from file-sharing websites at low speeds and not have ir corrupted after transferring all that crap via ftp... I rather buy the games for a few bucks when they go on sale every week...

I'd say this:

- Some places have real fast Internet, Gbps even, downloading digital version is way faster than go to stores or shop on Amazon. (And not every country got Amazon and fast shipping or local game stores.)
- Some game updates were larger than the original game, might due to 4K HDR stuff. The game discs were just for DRM purpose now. (It's even worse on Xbox, Quantum Break is now 200GB in download size, with or without the disc.)
- In some places, P2P would be faster than Sony's CDN, because Sony's server sucks. Xbox sucks but they got better CDN for real.
- You can simply borrow the disc from a friend, install it and patch the installed file to make it disc-free version. It has been done on 1.76.

The problem now is not about the game price anymore. The game is cheap, the console is even cheaper, and you can always resale your physical games. Just that some people don't want to spend money on games, I mean, who doesn't like free stuff? For me, I just wanted a way that I can run my physical purchases without change between discs, reduce the loading time and the disc reading sound is really annoying at night.

i live in ny and I have free internet because i work for an isp...they just doubled my download speed...i don't think it will be as much of a problem as you think to be honest...but the reason I am excited? Mugen on ps4! Imagine a Dreamcast Emu? The possibilities are endless. Don't be a hater. See you later...
