This is some pretty sweet news. I first saw it on this other forum, so everyone potentially begin to get excited.
Quote:
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!

...yeah... if I knew what this entailed, I'm sure I'd be a bit more excited. Explanation please? I'm guessing this will eventually allow... something... cool to happen. Am I right on that, at least?

I'm no expert, but if they can get into the flash, they should eventually be able to create custom firmware, much like they did on the PSP.
Could be interesting for homebrew etc...i just hope they are unable to create and isoloader for the PS3...i'd hate it if all the little pirates killed the PS3 like they did the PSP.

Actually it could lead to custom fw or downgrading fw without infectus.

Yeh, more people bought the PSP, but not many good games were made for it, as the developers didn't get anything out of it ('cos people were just downloading there games for free).
If the PS3 ever becomes as easily hackable as the PSP, it can only be bad for it in the long run.

@-ibizagti-
You talk about killing the PSP/PS3 by hacking it but yet you contribute to the PSP hacking scene by modding your PSP? Contradiction?
As someone here stated (cant remeber) but I hope they do hack it as it will open the full power of the PS3 and alot more potential.

Having a hacked PSP does not mean im a pirate... The PSP (and TOOL battery/memory card) were given to me, i hacked it to allow me to use homebrew programs (mainly Bookr), and to allow me to play my ORIGINAL ps1 games on the system.
Im proud to say i have NEVER downloaded or played any pirated PSP game on my PSP...so not really a contradiction at all.
EDIT: spell check

Theres a major flaw with that logic, Sony makes money off of each psp sold but they're still loosing money off every ps3 sold. Meaning sony is dependent on software sales in the ps3 market, and if they loose the software the ps3 will go down with it.

Well this thought is true if all people who use the iso loader (if one were to be developed) only for pirating. Plenty of people have modded consoles with mod chips/firmware flashing to be able to run homebrew, and have not committed any acts of software piracy. It does have it's legit uses without screwing sony. They may not buy as many games because if homebrew apps can be run, with legal games on it.... then hey... too bad. I think the systems should be "open" in that sense anyways, but it never would be.

I agree, but the system not being hacked in the sence of piracy is the only thing the console has going for it in the eyes of most of the game developers; and I don't want crappy 360 ports of every game for the rest of the PS3's life.

Shoot we get crappy 360 ports now and its not even hacked. I will admit that i used my psp for pirated games, but that was because psp games were so crappy why waste good money? As for the ps3 i would hope that you can only play a .iso form of the game if you had the original copy and sort of saved it to the hdd. If so more people would just rent the games. Im not sure if sony or developers get money off of rental sales, but at least it wouldn't be complete piracy because you actually paid money for it.

We're starting to get many more games actually designed for the ps3, I don't want to reverse the process. I do agree that almost all psp games are miserable, there were only 3 psp games good enough to bear playing: final fantasy tactics, ghost in the shell (possibly just because I'm a gits fan ^.^'), and Socom fire team bravo 2.

I'm going to say the games on the ps3 are either pretty poor, or are cross platform. I have a wii, 360, and a ps3. But the onyl games i have for the ps3 are UT3, Resistance, and MGS4. I will get resistance 2 and Killzone 2, but besides that, I feel like I don't have that much to look forward too. I would, love to see homebrew/any sort of hack on the ps3 to see what else I could do with it. Right now, i feel like I just paid for some over priced peice of equipment I use to watch blu rays.
With the addition of homebrew, that could spur a lot of "other" development for the ps3. Plus, I do think it would increase sales. But mostly for people who know about that whole scene.
But to say you hope the ps3 never gets hacked, I would be pretty disappointed.

I'm not even going to touch this one besides your last statement, its not the homebrew I have a problem with its the backups and iso loaders. If there is a way to hack the ps3 without being able to play backups and use iso loaders im all game.

lol @ canuckerz,
While I wouldn't call myself a fanboy, I would say it could be close. I'm definitely opiniated, but, I did buy the ps3. It's just my thoughts on the games.
Anyways,
I still also don't think having the isoloader would be a problem. Yes, it would be used for piracy by some. But others would use it for the very reason everyone publicly say they use it for... backups! I do know people who have modded systems, flashed drives, etc. who only use it for these legit purposes. It comes back down to the same argument of wanting one to be able to backup games you legally own (but everyone already knows all the points to this, so I won't waste our time). I'm hoping it comes, I guess we'll see.

This thread is interesting. So does anybody have any more news about the project? Like how more has it progressed?

I don't know anything yet. This is one of the first steps, but I posted this maybe a couple days ago.. and you can't expect anything that quick. But hopefully within a couple months this could lead to some sort of homebrew and iso loader for the ps3.

That is exactly that and nothing else,it wont lead to an ISO loader or homebrew.

And that's a very rare problem, its not like the psp where if one thing is misaligned its bricked.
