• Geohot: PS3 RCO File Edit

    PS3 Hacks , 19.03.2010

    Geohot has managed to do an RCO file edit on the PS3 using his exploit.

    To quote:

    As some people in the comments called, it’s an RCO file edit, just like RCO edits on the PSP(almost same format too). RCO files are resource files for VSH plugins, live in the dev_flash, and aren’t signed. To edit them on your system, patch your hypervisor to allow encrypted access to the partition(flash on old systems, hd on new), and mod ps3pf_storage. dev_flash is just a FAT partition, mount it in Linux and change what you’d like.

      so, what exactly could this one lead to? pretty text mods lol.. jk. Im pretty sure whoever guessed it really being homebrew enabled is months away was correct. But thanks for keeping the scene updated Geo.

      yyy it looks like really breakthrough ... I was following the progress of hacking psp from beginning ofc I used many of the mods and hack on my psp, and it looks similar. I think its a big step

      now that geohot can edit the RCO files, would he be able to edit VSH files as well? perhaps even replace the old boot screen, with a custom boot screen?

      The internals of the dev_flash is very similiar to the one on the PSP. The rco file geohot used is not signed, but some of the more interesting parts are signed and it will take some time to discover a method to change the values in those files.

      At the moment we are working hard on "patching" the Hypervisor to allow us more magic to be done

      I just wanted to give thanks to anyone and everyone that has worked on this. We have once again proven that "if man made it, man can break it."

      After the patching we will be able to have a "user friendly" exploit :D @ Disane, sorry to hear about the loss of your ps3 -_- Will you be able to revive it? Also, would it possible to use a USB A to USB A cable to transfer cable with PS3 system without the ethernet cable?

      Well, no. We are keeping a look out for any possible Lv1 exploits. Actually any lv1 exploit would help exploiting the GameOS lv2 as well. But frankly in Linux mode we already have lv2 access we only need a lv1 exploit to get more people into hacking who are afraid of bricking their machines.

      about the USB data transfer: I think in Linux you can already do that. If not then you can code a simple app that does that for you...

      I don't think I'll be brave enough to buy another PS3 and try installing another micro controller. Not to mention that a PS3 costs like 300 euros in my country. Without that PS3 my research will be a lot slower. But i can ask others to compile and run my code on their exploited PS3s. I also got some work to do that doesn't necessarly require a PS3. Like documenting stuff. So don't worry I'm fine...

      This does not seem like an exploit at all. Nothings signed, correct? So this isn't an exploit. Isn't this something any person person with a little bit of tech experience can do? I don't see something like this leading to anything, but I think the man (Geohot) can find something. I just don't think this will have anything to so with it.

      You have no idea how hard was this to achieve. Geohot is a really patient man I must admit. I would've given up for the 3rd try but I guess, It's just how he works. He never steps back, even when the PS3 is playing dirty on him.

      I consider this as a nice breakthrough, cause no one was able to achieve this before him...

      This little file edit is properly not the biggest thing that has happend, it's more like a learnig progress. You will properly see many "unimportant" edits before someone can put all they have learned into somthing we all can use. If you excpect someone to go directly from Geohots hack to homebrew, you're excpecting too much.

      BTW, I'm not an hacker, but I understand that you need to learn A LOT before you can exploit the PS3. If you're looking for homebrew, come back next year or the year after

      well considering you join date that you don`t seem like a just a fanboy 13 year old, i hope you remember team ice and what they did in the eraly days(wow seems like yesterday firmware 1.8 lol) but they did a hell of alot more than this i remeber they would do funny edits to games and playstation home like this all the time like in pain and stuff

      That is a very unlikely timeframe my friend, there is still 9 months left in this year, and im guessing about 2-5 months. they have hypervisor access, its only a matter of time.

      Zeruth: My timeframe is taken from the hacking of the 360. I followed the hacking scene as good as I could, and it took A LONG time from the annomunus hacker showed his hack at 23C3 to the point where real homebrew develoved.

      Its better to think it will take a year and getting it in 6 months, than thinking it will take 6 months but getting it in a year, or two

      Sorry for bad english

      Then again, They didnt have access to the hypervisor. Its easier to toy with a system that isnt as controlling. especially when you gain pretty much full control. Even if it takes longer than 6 months, im not going to be disapointed because im not actively helping. I follow the hacking scene of all consoles whether i own it or not, because of the possibillities homebrew can bring. But the hack shown at 23C3 was not the hack that led to actual homebrew dev. (call me out if im wrong).

      to my knowledge well ur wrong...

      I did the first 360 king kong to gnome hack see here

      YouTube - XBOX 360 King Kong Shader Hack to Gnome Live cd

      during this time access to the 360 was very minimal at first but eventually it improved and no the hypervisor was never conquered and all 3 cores still arent accessible to this day...but that original hack did lead to drivers/libraries being developed which led to xbr(hacked dash thanks to access/knowledge from previous hacks) and running with the broken signatures and 3 cores (wink wink) and heck may have even encouraged or helped dispersed stuff like xlast, hacked dev xb1emu, the official sdk being released in the overall scheme of things

      but back on topic GEOHOT ur my hero...!
