If we had the backup BIOS of the NOR Chip, do you think there could be an exploit somewhere in there (there is even a text file)?
OR
If someone was really good at programming and hardware, they could re-script the E3 flasher (any flasher) to look for/obtain certain files in the firmware?
Use the flasher to alter the firmware maybe...?

uuuhh??

the flasher dumps the whole nand/nor it obtains everything.

Use the flasher to alter the firmware maybe...?

talking about patching on the fly? that most likely does not work, files still to be signed and everything, it doesn't work...

I'm not a "black belt" karate guy, but I know some thing about x86 assembly...
I think he is saying some thing about patching RAM content...
Does NOR=RAM? I really don't know.
But I think that RAm can be patched on the fly without need of any key...
Unless Sony's Nazis does a crc check in each function call...
$.02

[Pockets69]

no NOR is not Ram

ram can be patched of course but not with e3 flasher lol

[TizzyT]

Dumping NOR/NAND will contain encrypted files etc iirc, and will only get us as far or less as to where we already are.

[Trivia618]

So everyone is stuck at the decrypting process?

Ok someone on Firmware 3.55+<4.11 and has E3 Flasher installed starts up game>4.11
When Ps3 checks if the firmware is compatible (and it isn't) we could have a script that will trick it making it think that we are running >4.11 (this will be done via program modified to be executed by E3 Flasher operating on the NOR at said time)
If only someone could make a homebrew app that will allow the dumping of the RAM, i'm sure it can be done from the use of software

PS: I'm just brainstorming, i'm 15 years old and i've never read the ps3devwiki

The private keys are "x" in this equation: y^2 = (x^3 + a * x + b) mod p
Which will generate said graph creating the ECDSA [“Elliptic Curve Digital Signature Algorithm”(digital curve signature)]

There is a nice puzzle for you here: http://kakaroto.homelinux.net/2012/0...gorithm-works/

[Pockets69]

i know all about the ecdsa i was studying it when kakaroto was studying it as well... it has nothing to do with this... or better it has but... i ll explain.

but making it think is not enough we need to have files (encrypted files) to get those games running so the ps3 can decrypt them, you cant just expect to run a game that requires a higher firmware if you don't have the required keys to do so, think of it as a door, you can't open it without the keys, there is no tricking the door no going around nothing, you need the keys, making the door thinking you have the key will not work, cause it does require the key!

GO RREAD IT NOW!!! its important.

Packages would have to signed also right? Can't sign the pkgs for the homebrew to play the games.

Even if someone made the software (which already exists iirc), how would you run it?
