Sony patched the use of those keys after 3.55.

buddy, im using 355

They patched the use of the KEYS in 3.55. Not the use of 3.55 with the keys. Sounds strange, I know.

Plus, it was updated. If lv2 decrypts GameOS, then using a different lv2 won't be able to decrypt 3.55's GameOS. Which would give you a YLOD.

lv2 is gameOS

They're updated. That's patch enough.

But you can dump all of lv0 with dual nor and a signed lv1.

I'm going to go out on a limb here and say..
The ones that were used in all FW before 3.55?

Unless i'm mistaken the PCK0 can't be changed? so if that's the case they just changed the algorithm for the hash to make new keys. Course at this point in my understanding, I could be just blowing smoke.

Hey what about decapping a Cell/BE and examining the efuses (PCK0)?
Anyone have 10 grand or so?

Their algorithm doesn't change. It's still AES-256. PCK can never be updated. PCK0 encrypts the bootldr with it's key. bootldr is the same on every console out right now in its decrypted state, but in it's encrypted state, it's different because it's encrypted with the PCK0. booldr encrypts lv0, while in its decrypted state, in a way, which is why everything after bootldr, starting with lv0 (not including metldr) is the same for every system, encrypted and decrypted.

Lol I wish. The PS3 scene would blow up if that happened.

I didn't mean they changed encryption method.. just prodded something to change the hash to make the previous keys unusable to the scene.

Somwhat, when, say, gameos changes, lv2ldr will need to accomodate. And if, say, lv1 can't decrypt hypervisor because it's not the exact same hypervisor with the same encryption key, then hypervisor won't load because it wasn't able to get decrypted. YLOD.
