215w ago - Today PS3 hacker Mathieulh reports finding a PlayStation 3 Firmware 3.56 exploit, although he states he has no plans to give any further details about it.

To quote from PSX-Scene (linked above): Well-known hacker Mathieu Hervais has reportedly found a bug that allows exploiting metldr, the bootloader and firmware version 3.56. Unfortunately, he refuses to release it.

So much for "unhackable" PS3s though... I am not giving any further details about it. Sorry.

Actually the revocation list exploit doesn't allow you to exploit isoldr, you could however sign a revoke list if you had the revocation list keys and knew the sign fail, and use that to dump isoldr. Metldr does not load revocation lists.

This has been tested, how do you think I could release the lv2ldr and appldr keys ? (about 24hrs before Geohot showed up with metldr keys) This has been tested, how do you think I could release the lv2ldr and appldr keys ? (about 24hrs before Geohot showed up with metldr keys)

You can also dump any loader using a signed metadata (including metldr) though that means you need to have the keys for it in the first place (kinda kills the purpose)

Your entire purpose is to get the isolated process (the code running inside the spu) to jump to your instructions

For exemple the following instructions will dump the isolated LS to the SPU mailbox:

loop:
rdch $3, ch29
lqd $3, 0($3)
wrch ch28, $3
rotqbyi $3, $3, 4
wrch ch28, $3
rotqbyi $3, $3, 4
wrch ch28, $3
rotqbyi $3, $3, 4
wrch ch28, $3
up_one:
br loop
br up_one

Of course you'll need a ppu payload to fetch the mailbox data. Metldr is trivial to dump now that you can sign your loader, but I wont say anything more on this.

Finally the problem with isoldr and the revoke list exploit isn't so much that the exploit doesn't work (it actually does) It's that the payload from the crafted revoke list overwrites isoldr keys (which kinda kills the whole purpose), You can however get the revoke list keys from lv2ldr or appldr using the revoke list exploit and then sign a revoke list metadata to exploit isoldr later on. (There are other ways to get isoldr though, including the 3.60+ exploit I have (but there is at least another I know of) Again, good luck in your endeavor.

There is more than one npdrm key. It's not been released because the ones who have the skills to do it do not remotely care about pirating PlayStation store games (obviously).

Finally, in related PS3 homebrew news today a PS3 FW Downloader application has been released which includes Official PS3 Firmware 2.50 - 3.55 and has Geohot, Kmeaw, Wutangraz PS3 Custom Firmware and 3.55 Downgrader support.

TBH you are such a liar. Since when most of releases never sees the light here? Today every new games are sold in a lot of stores, thats not an excuse. Its okay to say that games are a little overpriced tho, but if you have money to afford a ps3, you have enough money to buy at least a new game every 2 months or so. Stop the bs.

Well that doesn't meant that someone else can't include backup managers lol. He doesn't want to do it because it's crap in his eyes...

Geohot main reason for cfw was homebrew if I'm not mistake and backup managers were eventually present

two resons left, the rest is crap in my eyes o.o i respect his work, but i disrespect that he says "wah backup manager is bad".

i have around 30 games here in my room, all are original because they deserve to be bought. but i already owe my third ps3 because my bluray player got messed up...

yeah i have enough money to buy a new ps3 every second year, but there will be a point, where i only get this ugly, hardcore ugly slim ps3. and i love the fat one

sorry but for real, tell me 5 good homebrews who are worth it to hack your console, if there is NO backup manager.

for real, only a backup manager is really interesting. if there is no one, it doesn't make sense to me to hack my console with a hen.
