OMG!! I am soooo pumped right now, no system is uncrackable!

I take that back . This is FAIL until further notice...

» Playstation 3 Flash ECC Algorithm Reversed Article posted by XanTium | 22-9-2008 13:53 | Permalink | Digg News » Comment article From ps3newsDOTcom: First, a small technical explanation. We were not able to modify any data on the PS3's flash chips due to the ECC. The ECC is a checksum basically, that ensures whatever data is in the block is not changed or corrupted, and if it is it errors. So, the problem was since when we tried to alter data, the ECC would then in turn be invalid, causing errors, making the system not boot. We did develop a way around this, however, it was time consuming and quite slow. We used the PS3 to write data to the flash, then dump it, with its proper ECC, then rewrite to where we needed it. This would take hours on end! We were not able to regenerate the ECC since we did not know the proper algorithm. But now, we can!! After multiple tests done by NDT to see what the ECC algorithm was when the block was filled with some magic data, our very own RPS was able to reverse the algorithm! What does this mean? Simple, we are now able to in minutes properly edit a flash dump, regenerate the ECC and flash it onto the PS3 in order to experiment with flash changes. Using this, we have already found where the encrypted keys are stored for SELF's, PKG's, and BD Pairing among other things, more on that in the weeks to come. Furthermore, NDT implemented RPS's ECC regeneration code into his newest FlowRebuilder, which will be posted next week! Finally, this has already saved one PS3! Hacked2123's PS3, which bit the dust long ago due to a bad flash was recently fixed thanks to RPS's ECC Regeneration code which was built into NDT's newest FlowRebuilder! His PS3 had bad data that did not match the ECC data, resulting in a plethora of issues. However, as described here, it is now fixed! Discuss on our forums: forums.ps3scene.com

Yes, because,

Any progress is great though.

@Sublimewolf, why is it suddenly fail?

thats what this hack is, they just gained access to flash on retail ps3's, if you have payed any attention to it at all.

Just a sidenote, by "hackers" in the original post, Pirate was of course referring to the crew at *******. That was conveniently left out. Also, it's on a retail system, Infectus is not used, although it will also work. Toodles.

why the hell does everything start to get flammed? why can yo just except there a a few groups all working on the ps3 (would be better if they teamed up :-)) and progress is starting now.

I have been paying attention. maybe you should too.

Now, this is great news... I have intentionally put off buying a ps3 A: Because the price will come down and B: Because of great news just like this... Keep up the good work and hopefully we all will have something to smile about in the near future... I wish you all the luck in the world with all the new leaps your making, keeping the scene alive!!!
