76w ago - Following up on the
previous article and
update for the 3.73 JailBreak, today Sony PlayStation 3 Hacker
KaKaRoToKS has confirmed it is safe to update to
PS3 Firmware 4.00 for those planning to use the
exploit when it is released.
Below are some recent Tweets from him, as follows:
FYI, tested yesterday and the jailbreak still works on 4.0
so it's safe to upgrade (for those on 3.73)
Just got my progskeet today. Thanks
uf6667 for sending it!
It's so small!
Not much new to go on at the moment, but keep in mind the upcoming PlayStation 3 exploit will not enable PS3 backup managers such as multiMAN or Rogero as it does not include support for modifying Peek and Poke for lv1 and lv2 as outlined in the
FAQ that was previously posted.
"Does anyone else have Iris manager make their PS3 go nuts? I'm on Rebug Rex 4.30.2 and it causes the PS3 to apparently heat up so badly the yell...
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.

I hesitated a lot before tweeting about it, but a bug allows exploiting metldr, the bootloader and 3.56+. I don't intent to ever unveil 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.
