February 3, 2011 // 3:59 pm - Another update from graf_chokolo and Marcan42 who are working to bring OtherOS back to PS3, to quote:

I managed to boot an unencrpyted LV2 kernel from VFLASH. The decrypted LV2 kernel from Service JIG just made some strange sounds for several seconds and then did shutdown Normal unencrypted LV2 kernels boot normally. We could kick out lv2ldr from HV completely and boot enencrypted LV2 kernel always Working now on Linux bootloader. Stay tuned.

I didn’t use default.spp to boot decrypted LV2. I patched HV process which loads LV2 kernel, kicked out lv2ldr, replaced the function which loads lv2_kernel.self with my own code which loads just any OS from a VFLASH region It can be either petitboot, LV2 kernel or something else And dual boot is also possible with this approach. We could store several kernels on VFLASH and decide at boot time which one to boot.

And yesterday i found also out how to enable all debug and log messages in HV and HV procs and actually see these log messages Expect more soon. And greetings to SONY I will try today to boot decrypted 3.56 LV2 on my 3.41 PS3

If you could upload a binary image of AsbestOS for me please, i could test booting it today from VFLASH. Thanks.

Guys, i would be greatful if someone could upload me decrypted 3.56 lv2 kernel. Thanks.

If i got the right version then i just booted decrypted lv2 kernel 3.56 from VFLASH

Thanks for the images. Just booted your tftp image from VFLASH And i see UDP packets coming from PS3

From marcan42:

Don't confuse AsbestOS itself (a Linux bootloader) with the way you launch it: USB exploit, lv2 payload, lv2 replacement, or (now) OtherOS++

In other words, there's absolutely no reason why you couldn't use AsbestOS with his "OtherOS++"; in fact, you should! (once it's done)

Graf_chokolo doesn't seem to "get" AsbestOS. It isn't mutually exclusive with GameOS; AsbestOS built as otheros.bld is still a good idea.

graf_chokolo, I don’t think you “get” AsbestOS. It’s just a linux bootloader, in fact it would work great as otheros.bld or any other way of running it as an lv2 binary, and it’s more robust than petitboot (and smaller and easier to modify).

OtherOS + extra rights isn’t a replacement for AsbestOS, it’s an alternative to our original approach of replacing lv2 with AsbestOS. There’s already one released way to boot AsbestOS (USB exploit, which isn’t very clean/handy), Hermes is working on a runtime lv2 bootstrap for it (also not very clean but handy for people who like CFWs), there’s the lv2 replacement that we demoed but which isn’t out yet (which is clean, though can’t dual-boot GameOS yet), and once you release what you’re working on you will be able to just boot AsbestOS with it. Of course you could just run petitboot too, but where’s the fun in that? (we could’ve just used petitboot as a lv2 kernel for the 27c3 demo too, but AsbestOS is just much easier to make work and I already have a working new boot ABI using the devtree to pass the region1 allocation to Linux and patches that make it work regardless of whether the bootmem split is 128/128 or 16/240).

This isn’t a competition, I see no reason why AsbestOS can’t work great with whatever you’re getting ready

Btw, re: disk encryption, they use the same key and a NULL IV (can’t remember if all 00 or all ff) for every sector. It’s a very stupid/insecure block encryption scheme. There are flags for the sector read commands to toggle encryption on and off, that’s what we used to boot Linux off of a raw, totally DOS formatted disk with no encryption or lv1 regions.

Also, we thought about booting an unencrypted lv2 kernel too (I assume you’re messing with default.spp?) but we were very short on time and self was easier. Of course, you know a lot more about lv1 than we do

I think this blog is eating my comments if they have URLs…

Here are three binaries (compiled off of the public git, it’s just stage2_native.bin) with three different boot modes (config.h settings):


-hdd boots from a raw DOS formatted HDD (first partition must be FAT and contain a kboot.conf, same as we used at 27c3), -tftp boots from DHCP/TFTP (bootfile should be a kboot.conf), and -netrpc sets up a server that lets you read/write memory and issue hypercalls from a client on your PC, for experiments (see netrpc scripts in asbestos.git). See the AsbestOS readme for info on how to boot kernels with it (you need my ps3-linux.git patches). Git is at

You should run dbgcli on your PC on the same network as the PS3 to watch the debug output (even if you don’t set up the kernel/kboot.conf, if you get that it means it’s working). You can compile it from git, or here are two Linux binaries (64/32bit):


Have fun

yeah we may pay that one time price but what about the costs on making the games also? If you don't buy them then how will they make software money back?

Well I know what I'd do with that DMCA letter - WIPE MY ARSE ON IT AND POST IT TO SONY HQ!!!

This is pretty much Sony trying to control WHAT and HOW we play our consoles. Considering Sony make loads of different electronics and have done for yonks, they aren't exactly loosing out because of piracy. How do you think you play your backups? You need to buy a PS3 in the first place!

Dark days indeed. Civil war could be on the brink world wide as is. That state is already bankrupt. When tax payers hear what it will cost to handle this case and its financial fallout, they will be pissed! It wont take long to Make the taxpayers mad when they find out what the case is really about. Then they will realize that not only are they paying for this whole hoax, but in fact will loose yet another hard earned civil right to a conglomerate that seeks total dominion over everyone's property that they purchased.

(1) Do you have any consumer rights anymore?
(2) Why not try to settle out of court saving all concerned parties the the negative PR and fallout?
(3) Wont drawing this thing out hurt sales?
(4) Is it really legal to forcefully remove advertised features from current consoles by means of entrapment or blackmail?
(5) When the jury here's the words "Multimedia Computer Entertainment System", wont they agree its an owned multi-function Computer and not just a game player, after all "It Only Does Everything". (poor choice of slogan when they consider all the recent removals of key features.)
(6) Will it even be possible for a California jury to hear the words "Video Game" and take it seriously?
(7) would it not be a better idea to charge him in his home state where the alleged offense happened?
(8) Why is all home brew being targeted when the case is really about piracy?

Just trying to understand a hypocritical and incoherent legal dispute with more holes in it than Swiss cheese. People should think carefully about the true implications of this dispute and its aftermath. I only ask the question because no one else has.

The only thing i find bothering about all of this is that we bragged about more exclusives and we supported the company that gave us this piece of hardware. Most of you say that you wanted to use it as a linux based computer which i have no beef against i wish they kept the feature too.

All i want you to do is imagine u investing millions of dollars behind a piece of hardware that would allow people to play games and you would get SOME of your money back bit by bit based on how many games sold (yes i know that now they make a profit per ps3 sold but that has not always been the case).

Wouldn't you be a bit mad if people started hacking this piece of hardware you created and you could not make money back on it because now people are downloading games off the internet. I also understand some of you are using this for LEGIT HOMEBREW, but i've seen alot more people saying how can i play a game from my hard drive without even thinking about playing homebrew or creating it.

I personally will never CFW or even jailbreak my ps3 just so i can support sony and the developers instead of stealing a game and making them lose their jobs.

Sony will just use their time here, then go back to their offices crying that they spent so much time in that warm court room.

"Trafficking a device that circumvents effective access controls, and/or Trafficking a device that circumvents effective copyright protection measures."

Since when has a few numbers and letters been called a "device"?

I have a few Romanian sites doing nothing. I might start mirroring all these taken down sites there.

If everyone mirrored a taken down site then $ony will have fun trying to censor the internet which they cant. It's a useless fight for them and they will always loose. Why do they even bother? I keep saying they have more money than sense and they are showing it with every move they make.

lol, Sony's beginning to look pretty desperate. I mean seriously, good luck disappearing any file thats been online for over a month nevermind some tools that have been downloaded by thousands of people.

I have a feeling that the Streisand effect is gonna kick in on this, and the keys and mirrors of everything are going to be all over the place.
