PS4 Firmware 5.50 has been released, rumors say 5.05 Webkit exploit still works
Sony has released firmware 5.50 a few hours ago. The list of new features for this firmware is pretty big, including support for custom wallpapers, quick menu changes, changes to notifications and better ways to filter and organize content from the library.
The official playstation blog has a good summary of what this new firmware adds.
But of course, for the scene, what matters is whether the recently released 5.0x Webkit exploit still works. Early rumors say that yes, it does, however this would still need to be confirmed by a few verified hackers to be 100% sure. And, to be clear, a usermode entry point such as a webkit exploit is nice to have, but is only the first step to full control of the device: A kernel exploit is required to consider the console fully hacked, and no hacker has stated they would release such an exploit for 5.xx at this time.
Independently of that, the advice for people who expect to hack their PS4 is, and always has been, to stay on as low a firmware as you possibly can. It’s easy to upgrade when needed, but it’s impossible to downgrade.

But it seems this update doesn’t improve overal stability, perhaps that’s why the exploit works? 😀
yeah again we will have to wait a year or so for 5.xx kernel jailbreak when 6.xx will be out – really a great scene comparing to PS3 one :/
I bet you can do a better job than these amateurs. Go ahead, hack the ps4.
I don’t really get why trolls exist…
Why is it impossible to downgrade the firmware ?
Its because of eFUSEs. More information here: https://en.wikipedia.org/wiki/EFUSE
This wouldn’t apply to something like an E3 Flasher though? Anyways, PS5 is on the way since Sony is letting these exploits be released now. RIP PS4.
But people who were on 5.50 beta were able to roll back their fw to 5.05. If Sony can do it in software, why can’t others (with the proper knowledge)?
Beta firms aren’t designed to blow the eFuses (assuming that the eFuse claim is true).
Honestly, I fail to see where the eFuse theory holds true on the PS4. Haven’t seen any of the major PS4 hackers say anything on the usage of such.
Sony doesn’t use Efuses to prevent downgrading , instead they use hashes in syscon’s nvs
I wouldn’t say it’s easier to downgrade , but it’s not impossible .. maybe one day?
I couldn’t edit my comment (that is waiting moderation for some friggen reason), but there is no evidence to support or debunk eFuses currently.
Unless Mathuleth or QWERTY explicitly says otherwise, I highly doubt the device uses eFuses, but without such confirmation, it is indeed possible.
Ignore the last comment.
Let’s debunk the eFuse BS once and for all:

Lol that’s what i told you , using hashes gives them more control over the system unlike the efuses .. at least that’s what i believe
Because nobody’s made a downgrader yet.
First
There’s still a /dev/bpf kernel bug in 5.0x firmware. If it is patched in 5.50, there is hope for an exploit to be released to public.
why don’t just release kernel regardless patched in 5.50 or not
If it is released, Sony can find it and study the exploit to patch it.
well great, now we can wait till the end of ps4 era. What if Sony will never patched it?
Believe me, $ony will do everything in their power to patch it….or at least screw the consumer in some way.
Yeah, I understand the point of waiting for a higher firmware maybe in the first 2-3 years of console lifespan but after a certain point it becomes kind of self defeating. If it’s only at the end of the year or even next my interest has just gone from this.
That be the best situation as every ps4 would be hackable at the end of it’s lifespan making piracy not harm the developers and the games would be able to be preserved as well.
If the exploit isn’t patched, that probably mean no public kernel release?
Me Editing: The thing that qwertyoruiop havent tweeted since he started updating to 5.50 (two days now) gives me hopes because if the exploit from the previous versions works it wouild have worked few hours top since his updating and he would have tweeted about it. Hope the kernel exploit will be released soon in a matter of days (till Monday).
did u try the 407 kernel bug ?
im on 5.50 i confirm the exploit still works
i to wondered how i could update to 5.50 beta and downgrade back to 5.05 and back to beta. that would be fantastic if you could install a hack that was seen as “beta” and downgrade to OFW whenever needed. (coming from someone with ZERO knowledge of such things, tho)
so, Why is it that those guys want to wait until its patched to release the exploit. they say, if they release it, it’ll get patched, but they are going to wait until it gets patched? it still gets patched either way. whats the difference between letting it get patched now vs letting it patched eventually?
Because it’s exactly as to why $ony didn’t patch it in this update. If $ony doesn’t know about it or have access to it, then they can’t patch any further techniques to it.
If you have an exploit that sony doesn’t know about what would you do? Basically experiment with it on a higher firmware , maybe you can find something cool? Or find a way to use the newer firmware files on an older version say to spoof or enable some features or make a custom firmware (like the current vita situation) or maybe find more exploits
Because they’re selfish @$$holes who look down on others and condemn them for wanting “backups”, when they’re just as guilty as the rest of us.
*** idiot. NO, it’s important to have multiple points of access. If they released every exploit right now, when the VERY NEXT firmware came out. there would be NO KNOWN EXPLOITS that work, and NO HACKER would have access to that or any future firmware until new exploits were discovered.
Hoping for something before Spider-Man comes out, cuz after that if an update is required I might have to commit…..that is unless of course I splurge and can find a low FW PS4 Pro.
5.05 Webkit exploit still works i tested…..
