WIP: PSGrade code released, but no working keys yet!

[garyopa]

I sure the v3.15 was dumped long time ago, why dump it again, just dig up one of the old HV dumps.

Yeah the key is definitely out there, I just don't know where to find it.

accorking to graf_chokolo, to get the ps3 to decrypte the master key, then you have to call "Verify Response" and the master key will saved in plain text. it is called when plugin a jig, and that is what PSGrade is.
once we have the key, we will have a working jig :-)
And no 3.41 is no good even if you have dumb the HV

here is my discussion with graf_chokolo:

No problem dude, I'm sure someone will have the key in no time. Hopefully this works!!! Thanks for your contribution nevertheless.

why cant we use the dumps that are already circulating around the internet from Egohot and DH's exploits from like months ago?

Even with the key, it will not work on an unexploited ps3, as said from chokolo to you axis:

@zAxis

PS Jailbreak people “borrowed” some things from $ONY that allow them to initiate the challenge/response protocol between USB Dongle Authenticator and unexploited GameOS :-) I don’t have these things and will not use them :-) I can only initiate the challenge/response protocol on an exploited GameOS.

first you need to run PSGrade then do a 3.15 dump

[MRDOCA]

i wish you the best of luck with this zAxis. if you ever want a guinea pig to help test the downgrade give me a shout. always willing to help

[ToXiiC]

zaxis how are we supposed to try it if no further intructions given.
Try giving us some instructions on how to use the psgrade to set the barrier, scene is advancing i see lol.

so, it only works on jbroken up to 3.41? how can the original psdowngrader work on 3.50 then?
