Release: Fully operational dlclose exploit + Linux for PS4, by kR105
The name kR105 might ring a Bell to you because this developer has been credited a lot recently by CTurt on his PS4 hack work. Today, kR105 popped up on our forums to release something that lots of us had been chasing for a while: a fully operational dlclose exploit. He also emailed me to mention he has now integrated support for booting Linux straight from the PS4-Playground tools, and, icing on the cake, also provided the actual PS4 Linux files to use with the tools.
In other words, kR105 is closing the gap here, releasing everything you need to run Linux on your PS4. This is not a drill or a proof of concept video, people. The files are up for anyone to grab. I haven’t tested them myself though, because I’ve still been hesitating on getting a 1.76 PS4, but I’m regretting not having one every day that goes by. If you’re the lucky owner of a PS4 1.76 though (we have an article here on where you might be able to get one), now’s the right time to test this! Furthermore, there’s absolutely no reason to doubt this release is real, given that it initiates strait from kR105, in CTurt’s github. Also CTurt confirmed this release to me earlier today.
So, what was just released by kR105?
A fully functional dlclose exploit. The exploit had been released about a week ago, and several people had been able to take it further, but there were still issues on how the publicly available code was working, crashing as soon as the exploit was attempting to return to userland. kR105’s release fixes all of that, it includes root, sandbox escape and jailbreak. This exploit is what you’ll want to run your native code on a 1.76 PS4
The dlclose kernel exploit was released a few days ago
An update to PS4-Playground to run Linux. Another missing link here, that will let people launch linux without having to write their own loader. The launcher integrates the dlclose exploit if I understand correctly. From the Readme:
You need a FAT32 formatted USB drive plugged in on any PS4’s USB port with the following files on the root directory:
bzImage: Kernel image that will be loaded. Recommended to use this sources to compile it.
initramfs.cpio.gz: The initial file system that gets loaded into memory during the Linux startup process. This one is recommended.The file names must match with the above and you can have more files on the same USB drive. From there you can setup the environment to run from an NFS share or from an external drive via USB (recommended) and boot a complete distro!
A Compiled distro of Linux for the PS4. kR105 has the files bzImage and initramfs.cpio.gz ready for anyone to grab, so you don’t have to compile your own version. In his words: “those files should get you into linux with a nice bash console on your tv”.
Downloads
- You can download the new dlclose exploit from kR105’s github here.
- You can download the latest version of PS4-Playground from CTurt’s github here.
- You can download kR105’s compiled Linux files here.
Update: As pointed out by CTurt, you can simply download the compiled Linux files, put them on a FAT32 USB stick that you’ll connect to your 1.76 PS4, and test directly by going to the PS4 Playground live Demo here.
Wow, now that’s a good start for the weekend!
Wait… a second im confused … On the wololo website it says its possible to jailbreak your ps4 and pasted a link directed on to here, but i dont see no jailbreaking file. All i see is how to run linux on your ps4. Sorry I may seem like a noob but can anyone explain furthermore about this? Thanks !
Its complicated. The hacer who invented the way to install linux on ps4 did not want to crack sony system. He only wanted to allow instaling linux on it. Processor instaled in ps3 and ps4 are created by IBM. These are processors created to make linear calculations of high complex. Example – Long time agoo when ps3 was released on default it was possible to install linux. Then scientist created a super computer with 16 ps3 to calculate collisions of black holes. For few thousand they created a super-computer worth milions of dollars. Creater of this program did not want to pirate games. He wanted to create path allowing to use full potential of your console. But same as it was with ps3 aftere release of ps3linux it didnt take a lot of time to crack the system up, so be patient
The cpu of the ps4 is from amd same as the x1
Is there a way to use this exploit to play modern day games while still staying at firmware 1.72?
this is not a jailbreak
This is absolutely a jailbreak. It allows the PS4 to run unsigned code. No one has written some code to execute pirated games if that was what you were looking for…
i guess you dont under stand the theory of jail-breaking , its TOTALLY a jail break , what you mean is it doesn’t let you steal games .
Hi Guys I have a PS4 Never used with firmware 1.61. I bought it without games and went overseas. Now wanted to sell it as the games are just not worth the price as I use a PC for gaming…. until I read that has been hacked. So will I need to install 1.76 or Linux can be installed also on a 1.61? Is it worth to install this Linux or just wait for the CFW? What can I do with Linux on a PS4 when I already have a hi end PC? Will we ever see the possibility to play custom games on this PS4? How much will be worth if I decide to sell it? It is the Black model CUH 1002A. 500GB. Thanks!
it’s possible install pirate games with this?
why isn’t there any development for ps4 on 1.76? I don’t mean only piracy but anything! why?
I know right. Even I dont get it. I felt like the scene is alive working on an exploit to run unsigned game codes,,but then 1.76 gets cracked open, which is quite the achievement..and then nothing. This is why I dont have much expectation from them. I had left my ps4 on 1.76 for a longtime, until it became obvious that nothing was gonna happen….The 4.01 jailbreak brought something to the table, but i have a feeling we’ll still have to wait like a year from now. Yes I love custom firmware and free “unsigned game codes”
You see some more stuff being developed now, a lot of developers just don’t have the time to write something for the ps4 if they have to *** about compiling the exploit etc, especially knowing that hardly anyone in the mainstream has easy access to the jailbreak. Should see more stuff being written now

Hi just a thought. But can u use a hid/rubber ducky bad usb on the ps4 to open webkit and auto exploit. Oe even more. Have it open the guide program it to go to webkit site manual or automatic. Not sure if it can be done but I will say it. Can u not reprogram the user guide on ps4 to go to webkit automatically. Skip guide completely. Is thier any way the hid could detect user guide and auto exspoit. Just a few idea’s that’s all I am not in anyway qualified to say it’ll work or not.
