Previously JaicraB with TeamHades dumped the PS3 hypervisor LV2 (GameOS) and revealed how it was done, however, the dump was not clean and so work resumed until today.

To quote from the included ReadMe file: "This application will dump all accessible LV2 memory on a jailbroken retail PS3.

To run this app, place lv2dump_07a.pkg on a usb memory stick. Install the pkg. Then run LV2Dump from the XMB. It should run for approximately 20-30 seconds, then it will exit back to the XMB. There will now be a file named LV2.BIN in the folder /dev_hdd0/game/





You can access your dump by copying the file out with your own code, or the FTP application.

Before attempting another dump, delete the LV2.BIN that is in /dev_hdd0/game/ as the next dump will append to the file if it exists.

The dump is right around 8MB - which will let you take a look at the PS3's kernel.

Expect more tools from us in the future for the PS3."

Is it possible to reconstruct ELFs from the dump? The idea here is: Sony created (compiled) ELF originally then signed and encrypted them to SELFs. Upon execution they get decrypted and loaded into memory. If we were able to "dump" and reconstruct proper ELFs that would serve as a base for study, patching, ...

Build binutils for poweprc and use ppu-objcopy to turn a binary file into an object file and ppu-objdump to disassemble it.

what are we using to view these dumps... a hex editor and the ibm docs? or has someone created a "disassembler"?

Not sure if the assembly language is mips, or powerpc, or exclusive to the spu?

The funny thing is, the PS3 was out of warranty and I had no receipt, but I when I yelled at the guy over the phone and told him it was sony's fault the guy gave me a free 90 warranty and told me to send it in. I sent a letter with it describing that I needed the OtherOS and my PS3 was previously on 3.01 so I would be extremely ticked off if it came back without the ability for OtherOS.

Funny thing is, this PS3 isn't even mine. It was kinda just handed to me because I do electronic repairs anyways. I was like the 4th or 5th person down the line to receive it. I've had it for over 4 months just collecting dust. But when the news broke about the jailbreak I called them right up to get it repaired.

So I don't know who the owner is, I'm sure he doesn't care for it since no one has ever asked me about it. And hell, if he ever does then I can charge him for the repair, well, since it is fixed. If I never hear back from anyone then it's mine, fully working, for free.

WIN!!!

So now my only question is, when will the jailbreak/groove be ported to older firmwares? How close is this to happening?
