PS4 Jailbreak (PS4JB) 7.50 / 7.51 / 7.55 Work In Progress, Don't Update!

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.

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">

TLOU2 works for me on 7.55 PS4 Pro. Took a few attempts to get Mira to take but once done all good. One thing that mine did, not sure if others had the same experience.

Once the exploit worked it kicked me back to the home dashboard with no message etc, so was unsure if it had worked until i checked and saw debug settings now present.

Good Luck all and Props to the Devs who make this possible and add a bit of joy into our lives especially in such dire times! KUDOS!!

I am on 7.50. Is there a working payload that will actually play new pkgs at this version. If not I will upgrade to 7.55

 

[tsh2005]

Thank you sooo much

 

[noc1]

so is it safe to update from 7.50 to 7.51 or 7.55?
none of the jailbreaks i tried (selfhosted) worked.

7.55 has the most stable exploit till now ... mostly 4 tries then you are in .. games are running without any issues .. still could be more improvements I guess

 

[TheBigSpaniard]

When you receive the not enough free system memory error, do you need to restart or can you just keep going in that loop? Not having a lot of luck so far

 

[noc1]

i did restart and clearing browser stuff but everytime i get to the
"[+] Succesfully got addro/fakeobj" notification my ps4 shuts off sometime later and the light stays white for aprox. 5 sec then nothing. pressing the power button it just beeps, a second time it boots as if nothing happened

 

[TheBigSpaniard]

That's what I get and am doing, however. It is crashing when I see the 'You're all set'

 

[raghu89]

Kudos to all the devs involved. Waiting patiently for more stability (7.51)

I have re-initialized my ps4 to install firmware 7.55. I configured alzif dns to block updates and execute the exploit using my own host. The problem is that when I get a Kernel panic and my ps4 restarts, I have to setup my ps4 from scratch, as if it was new. Is this normal?
