Yes, this will get ugly for sure. Units bricking and then Sony refusing to touch them, even if they're under warranty since he mentioned the possibility of using this with slims.
I wonder if people actually realize that manufacturers refuse to support units with CFW. It's no different than mod chips of yesteryear.

I have no clue what PUP means (Playstation Updater package?). I understood this as as installing a modified 3.21 FW, which is disastrous if this is possible without messing with the hardware. The SPU Isolation facility should prevent exactly this, having a trusted facility for the most important duties which remains intact even if the rest of the system is compromised.
Even if its "just" adding/changing some modules (which would be surely be bound to get complicated to ensure everything stays compatible).. its still horrible if patching in GameOs is that easy.

Yeah, its possible hes just faking it, but I`m giving him the benefit of doubt.
Its one thing if he can break in via his OtherOS exploit, requiring opening the PS3 and glitching the hardware to gain access.
Its an entirely different thing if he found a hole in GameOS which doesnt require any hardware-"hacking" and works even on Slims.
I came to think of one thing, if he actually hacked the firmware, ie. the real 3.21, then he must have done something very clever since that Firmware removed the Other OS function and he got it back. In my opinion there is 3 options:
1: He just changed the version number
2: Sony did not remove it completely, but let the function stay and only "disabled" it from the menu.
3: He actually created his own firmware that would boot the OtherOS
Giving the guy the benefit of the doubt, I think we are talking about #2.

Breaking down and extracting the PUP file, changing or replacing a signed module is basically Sony's worst nightmare and that's exactly what he's saying he's done here. My guess would be it's a straight component swap from one firmware to the next, but it still shouldn't be possible.

Maybe there's some kind of loophole which enables someone to mix and match signed modules? So he's basically taken a module from an older update and somehow injected it into the new update?

He said that he has read and write privileges everywhere. After the cell boots up, loads, decrypts the firmware, I would imagine his pulse is sent. Then he simply rewrites the memory location of where the firmware version string is?
I really wish someone who knows about this stuff could write up an article.
I feel the same way, this is all over the place for me, if he can "patch" the firmware then how deep is he actually into the system. I would say neck deep, but then, if i understand it correct, it´s more of a OS running some basic stuff like Friend lists etc. The more complex stuff is programs that is started from the XMB, like gallery, Vidzone, Home etc...
But it does have access to the Account information, it includes a video player, music player and stuff like that. The important Protection in regards to games seems to be decoupled completely from the XMB, it essentially starts games that then has to run though the build in protection.
But maybe it opens up Region free Blu-Rays since the Blu-Ray player is a part of the firmware.
Maybe Eastman could really get what he wants here, access to features that he can´t live without and noway of playing pirate games
