PS4 Kernel Exploit for FW 5.53 sneak-peek by @Mathieulh --- UPDATE: Latest FW 5.55 as well !!!

Remember when we talked about that the PS4 is still in search of it's full potential and that the Developers are still hard-working with Exploits and other cool stuff for newer System Firmwares - like @SpecterDev does with System Firmware 5.05 - then you shouldn't be suprised that other great Developers like @Mathieulh are also using their research for exploiting even newer System Firmwares - as he showed it with his little "sneak-peek" for System Firmware 5.53. This would mean that the lastest System Firmware from Sony would be exploitable and Homebrew would be possible - by the current state of reading. --- UPDATE: @mathieulh gains access to a Kernel Exploit on System Firmware 5.55 as well --- Check Down Below for further information!​

Before you wonder, what the hell is he talking about in his tweet with all this confusing crypto messages, it seems that he was able not only to dump the latest System Firmware, but he was also able to decrypt it - which could lead into further investigations for a Kernel Exploit on System Firmware 5.53 - if there isn't already one. But before you get to excited, such research needs some time, not only for developing and making them compatible for your PS4 to install it by your own.

But there are also good reasons not to publish the exploit right away. One point is that as for previous exploits, a compatible SDK is still missing, which means that there is still nearly no useful Homebrew Applications available for developing and running from the PS4's Operating System - if you don't count installing Linux on your PS4.

But there is also the fact that if he was able to make System Firmware 5.53 fully exploitable, then this would mean as already mentioned above that we speak here about a Kernel Exploit for the latest System Firmware. There could be some advantages, but also one big disadvantage, namely that Sony could easily fix it in their newest System Firmware. Then the cat-and-mouse Game would begin again from the Start and a new way would be needed to find a new method to exploit even a newer System Firmware released by Sony.

Small UPDATE: "Sneak-Peak" for a Kernel Exploit on FW 5.55 as well !!!

@mathieulh gains access to a Kernel Exploit on the newest System Firmware 5.55 as well and shows in a humoristic way that both Sony and other Developers aren't a challenge for him

update via the recovery menu and select storage. before that, though, make sure updates are blocked and delete the two folders for blocking updates if yo u used the update blocker. you'll need to find another way to block updates temporarily (disconnecting from the internet?). update, then reapply the blocker.

What did u mean about delete two folder please i wann to follow your steps please?

it's easier to use the unblocker payload. that should do it for you. I'm now using the sandisk connect, so I cannot ftp unless I swap SSiDs. I needed an easy way of doing this. this is only if you've used the blocker before.

That blocker payload permanent or need to do blocker payload every time run like run han every time i run ps 4

it's permanent. it creates those two folders, so an update will fail.

 

@pinky And then recovery update also will fail? Just asking, I don't know, but if Sony copying files from the usb in the same way as from internet, I see possible brick risk.

my guess is that it still prevents it. afaik, an update from psn can still be installed from the recovery menu, so an update can exist in that folder. if the system detects an update, it will try to install it from the home menu, but in the recovery menu you can select to install an update from three places. my guess is that os of the system creates and places the update in the folder; then, the rest of the hdd is populated outward from that folder.

I read kiwii's guide, and I don't recall it mentioning this. best thing to do is just run the unblocker payload. I saw those folders on my system, so I hope that they were removed. I've gone completely offline, and I'm trying to learn how to use the sandisk connect with my system. I haven't done much with it. I've only brought up the selection screen and ran the unblocker. now, I just need to update to 5.05. I'm still on 4.55. I think there's now a way to use your original save via pkg change too.

 

you can use your original saves as long as you add the keystone data to your ps4 pkg

 

@pinky Why You need this payload as there is already FTP payload? You cannot create/delete dirs by FTP client?

And if authors didn't test this, I wouldn't recomend to block updating by blocking a firmware caching on HDD in case this prevent user from install firmware from USB (i.e when OS is broke and user must reinstall fw from recovery level). Better idea is just black list update servers on router (BTW someone have update servers list?).

there's an ftp payload and a separate payload for deleting the update folders and yet another one for adding them in. you want to add them in in order to block updates. I can't do any of these things manually since I'm completely offline. I'm not sure about the dns, but since my ps4 and my laptop are using separate SSiDs, I don't believe ccproxy will stop updates from downloading. that's how I've been blocking them. there's a list of urls to block in my ps4 tutorial. I found those servers with cc proxy. it's probably overkill, but it does make it error if you try to update manually and nothing will be downloaded.

 

I don't plan install any middlware-malware. I think about blacklist on router which is safe and should works perfect until of course we know the specific address (including backup addresses).

So thanks, I will look into Your tutorial and test it in near occasion.

5.05 backup OMSK to 5.55

Hi!
Does anyone have a live link to Backup OMSK (4.40) 5.05 - 5.55?
