Following fail0verflow's PS4 Crashdumps / Kernel Dumping and PS4 Aux Hax Documentation alongside his recent PS4 Sflash0 Pack Tool, PlayStation 4 developer @SocraticBliss made available a PS4 Crash Dump Decryptor Python Script for scene devs on Twitter today.


From the Tweets below, here's what he had to say on it: "Still tweaking this somewhat, but decided to take a swing at fail0verflow's PS4 Crash Dump Decryptor script (since at this point its fairly outdated), enjoy!

Thanks goes out to notzecoxao, CelesteBlue123, and most of all fail0verflow! :)"

2) Replace HMAC KEY # with the actual key
3) Have orbiscore-systemcrash.orbisstate in the same directory
4) python

@sanyo23 ok. I understand your point.

What i see with that is the dev's had those exploits and cause they were patched they decided to release it to public. These days, they might have some newer ones (or not) and they don't see the need to release it to public because since 1.74 you got 3.55 / 4.55 / 5.05 and some ports to lower firmwares and all of those have good tools for the homebrew scene.

Also, all have one thing in common, they were all patched. And some of those (if not all) were public CVE's or known bugs that S0ny "forgot" to fix. If some new exploit exist that isn't patched or it's a known public bug or is a public one that is under the radar so far or it isn't known, so if they don't patch it, it won't see the light of day, till some of the dev's release it. I've never seen some 0day PS4 public exploit release.

Despite most people only want a new exploit for backups, the dev's like to know how the system works, research, challenge, learning, whatever... so they don't see the need for a public release. With this research they might find something that might open PS4 "doors" to public for good, like you have seen in previous scenes. And this might take long.

Don't get me wrong, i want a new exploit to the PS4 scene but also i do understand if they don't wanna release it. Because exploits are limited. There isn't a unlimited chain of exploits ;)

Better to have a "ultimate exploit" than some that might get patched in just a few days. For that, patience is the key. Or just forget about it and update to latest firmware and enjoy online with friends.


I mean I get it, people are pissed because they can't run the latest games, so they vent on forums, do they deserve the games? No not really, but I guess that's besides the point. If you want homebrew, you got it.

For the people who are waiting for new exploits for playing these newer games, you are essentially waiting for Sony to patch the ones that are still out there. Once Sony patches the exploit, there is a higher chance of it being released publicly, as it is no longer of any use, there is hardly any chance that working exploit will be released publicly before Sony patches it. These systems are just way too secure for any one person to lone ranger it, plus it would be a huge waste since Sony would just patch it the next software update.


Can you install the game on an external hard drive connected to the current version of PS4, connect the external hard drive to the PSP in version 5.05, transfer the game to the computer via FTP, reduce the version of the game to work on 5.05?

You guys make me lol

PS4s are cheap and so are the games.

Buy a second PS4, update it. Enjoy life.
