Clarification regarding the 5.05 kernel exploit and jailbreak
Most people seem to be very emotional and not understanding the hacking process so I though I should try to clarify the recent 5.0x kexploit situation.
Many of you recently learned that qwertyoruiop has a 5.05 kernel exploit. That is not news, in fact he even confirmed he's had it for 8 months so a lot of people got very upset for some reason. There is a reason for that and it's very simple and also smart and noble from qwertyoruiop - he treated it as a 0day vulnerability. For those who don't know - 0day vulnerability is something that a hacker knows but the hackee (eg. Sony) is not aware of. He was waiting to see if that vulnerability is still present in the next version 5.50, however it was fixed by Sony. Hackers protecting their 0day is common practice because it could pay off in the long term.
I'll continue with that kernel exploit is not jailbreak. There are several patches that need to be added to the kexploit code in order to achieve jailbreak. Only then will it be able to load HEN. A few weeks ago qwertyoruiop tweeted "I know at least one is vulnerable to the 5.x BPF bug - and hopefully they will patch it soon." He is not referring to Sony but the hacker(s) who are trying to patch the kexploit, to make it usable for jailbreak. See this link if you want to get a better understanding of the patches - https://github.com/Cryptogenic/PS4-4.55-Kernel-Exploit. However, apparently the 5.xx work very differently as compared to 4.55 so that has proven a challenge.
Yesterday qwertyoruiop posted the following series of tweets https://imgur.com/a/qysJi This describes another 5.xx jailbreak challenge and that the guy is working on it. You can see that he's using his techniques across different platform which is very, very beneficial for the homebrew world. This is good!
In conclusion, I want to remind that this is nothing new. I just hope this makes people less confused and frustrated. I am not in a position to give any estimation for a jailbreak, as I'm not involved at all, so my personal advice is that you be patient and appreciate all the hackers' work. It will come when it's done. In the meantime 4.55 Slim consoles are still fairly easy to find so you can get one and have fun with it until there is a 5.05 jailbreak then you can sell it and upgrade to a Pro.
