(adsbygoogle = window.adsbygoogle || []).push({}); There is a lot of talk about a 4.31 JB. All of the jailbreaks out their use a private key for 3.55 and the pkg sign key for the 3.55. This means that you can only install it on 3.55 or lower.

Why we can't find the 4.31 private keys?
The reason why is because its almost IMPOSSIBLE. 3.55 and lower didn't have encrypted keys but every other firmware higher than that does. That is why we have been stuck at the 3.55 CFW for years. The private key for 4.31 is in the trillions or more plus it has a digital signature. The chances of a 3.56+ are VERY slim. So don't count on it and if you find a youtube video saying that there is. Its a fake.

Why was there a 4.10 CFW then?
It wasn't a CFW, it was a MFW which means it has demo mode on it. Also it doesn't have the private keys and the pkg sign keys. That's why you couldn't install pkg files on it.

How did Geohot JB PS3 then?
Back before 3.56 there was no encrypted private and pkg file key. This made it much easier to find it and modify it.

If you have any questions ask me!

Actually there was a encrypted private key, but the encrypt system (ECDSA) didnt work correctly on 3.55 or lower.
On 3.60+ the ECDSA bug was fixed, and worked as it should.
So now the encrytion uses a random number every time for every user for every hour
But on 3.55 it took the same number for every time every user every hour.
And it was broken that bad that they could easilly put in just random numbers and the PS3 still thought is was official Sony file

thanks man, I do understand it now.

jezz no wonder the PS3 scene sucks ass! no offense to many linux loving devs to even care less about the damn scene for those who Patiencely waiting for a solution to install or downgrade to cfw from ofw (Those who bought a PS3 this year or 2011 last year) and wanted to hack their consoles finally and realise they can't!! yet they care more about stupid 3.55 rather than having no progress at all! sad i tell you smdh!

well I hope I sound like a dck but if these lil noob want a jb that bad just buy one off the internet its that easy

I thought everyone knew this lol, it pretty much gets spammed on all the threads here

not 3.56 lol

There is already a stickied thread in this section that goes more in-depth than this.

Can a mod close this it has been said over a million times and everybody knows this...
