Following the 7.50 PS4 Kernel Exploit (KEX) that was confirmed working with 7.51 and 7.55 OFW alongside updates to both AutoBackPort v1.11 and PlayStation 4 Tool Box v2.1.7.30, today @sleirsgoevy (Twitter) implemented @Al Azif's (Twitter) dynlib_dlsym patch earlier noting it does not seem to fix payloads while recommending scene devs remove line 525 in jb.c (included in the Depreciated .zip below) and recompile to fix the crash when forking webkit. :geek:

As always don't update your PlayStation 4 Firmware until PS4 Scene developers have time to sort everything out, additional details can be found HERE for those interested and we'll update this article as progress is made. 🔥
To those having issues self hosting add ./ to the JS links at the bottom of the exploit html so like this:
<script src="./webkit-7.50/external/utils.js">
PS4 Jailbreak (PS4JB) 7.50 7.51 7.55 Work In Progress, Don't Update!.jpg

⚠️ Warning: We removed a bunch of redundant posts asking what's already covered in the OP and banned several users... needless to say for security reasons we don't allow posting random 'exploit host clones' here... especially those containing obfuscated code, bitcoin mining scripts, ad-infested link shorteners, news feed spam or requesting donations because some asshat decides to profit from hosting someone else's work.

I'll be going through Twitter and adding those from trusted scene devs to the OP as time permits, until then avoid posting Tweets in the forum as we don't need 200 people spamming the same 5 Tweets repeatedly.

:alert: Those ignoring this checkpoint will be permanently banned with no additional warnings nor recourse. :alert:


I'm pretty new here and still on 7.51. Should I upgrade to 7.55? And what does Mira/Hen do? Is it there to load the games or what do these do? An explanation would be awesome, until now I just had Wii and Wii U devices, so if there are any similarities to Homebrew it would be easier to understand :)

But big big thanks to the awesome devs, really appreciate it!! :)

@TECHNOFAB Looks like 7.55 is the slightly more "stable" fw amongst the 7.5x firmwares. Though none are very stable like 5.05. Most people usually use a website that hosts mira/hen payloads, which allow for accessing the debug menu.

There you can install fpkg games. After that you can play the game, but you need to successfully run the exploit every time you restart your console. Rest mode probably won't work so that is pretty much every time.


I keep getting
[!] Failed to setup a relative read primitive
Is this normal, and i just keep trying? or i am doing something wrong.

Also, Thank you super Devs
