Video: PS3 System Crash During Firmware Investigation

I think the hardware is crashing due to hardware incompatibility, yaboot is build for machines with OpenFirmware like Pegasos or Sun SPARC.

Need a way to recreate a parsable elf from self, someone should be working on reproducing encrypted self files/signing files? which i suppose its a big task if Sony's process is unknown.

I don't know much about the topic, but im guessing thats the only way this could become useful.
And in the other thread about libtiff, someone already mentioned the CELL's protection to block unsupported code, (someone would have to help me out on this) which im guessing wouldnt work in a hard crash. or "locking out" hv or tricking it/time attack.

Wouldnt it have been great for Sony to release launch JAP model without the elevated administrator level/hv? A lot more would be known. So this post is pretty vague (because im bored) but would recreating the tiff exploit ala psp work with the ps3 (obv different), or not because of the hw? would it need someone specialised in libtiff etc (as mentioned on the other post about the soft crash)...

is there any room for explotation on the boot process/trust chain?
i might be completely wrong though... not very ps3 tech.

This may seem like nothing to others, but it's more information about the ps3.

Eventually (hopefully) it'll be hacked.

There's been quite a bit of new stuff found out on the ps3 this week

Keep up the work.

Anything is possible :P

I'm confused!

If the self ISN'T a PS3 file, surely the encryption would make no difference as it won't be recognised by the PS3?

If it is a PS3 file, why is the outcome (flashing yellow then red) of any interest? Is that particular light sequence telling us that the code has overflowed in some way?

Sorry, i don't understand all (i don't speak english regularly). What can we do with this ?

[duranza]

This is just the first step to hacking the ps3. When we find the decoder sequence we'll be onto something.

nice work, very interesting..
