Video: OpenCobra Cobra USB Dongle PS3 Payload by Oct0xor Demo


Sponsored Links
110w ago - Following up on the PS3UserCheat and True Blue unnecessary DRM-infected dongles being hacked alongside zadow28's work, today PlayStation 3 developer oct0xor shared a video of his OpenCobra Payload which aims to render the current Cobra USB dongle from Max Louarn useless.

Below are the details from his [Register or Login to view links], as follows: "First I am going to say that this is not going to be an article, just a first blog post and some info about my recent project.

Finally I got my hands on cobra it was quite a lot of time since I touched this last time. There was s good things happened since then eg. I reverse engineered usercheat and true blue, had done a lot ps3 and not ps3 related hacking. There was a bad things eg. BlueDiskCFW, lv0 leak, a lot of devs leave the scene...

Cobra was for me really "the last" thing I have to do.

The last time when I worked on this I didnt had a dongle, and all what I had was a dump by JaiCraB. I reverse engineered it as much as possible, figure out almost all tricks, encrypton and etc. And figuare out that it reads a lot of data from dongle, and I cant do much without dongle itself. Thats why I put this project to the back burner.

Well... I had never buyed anyone dongle, and I never was not going to. All my dongles was donated (thanks again ) but not that time.

it was hard for me to make this decision but a few days ago cobra finally shipped to me...

3 days and now its all over.

Security is good enough, but not without big security risks. But it still the best crypto/obfuscation what I had seen on ps3. Sony have something to learn from this guys, especially now.

Cobra / True Blue almost identical, have the same source code, if you ever hacked 1 thing, 2nd wouldnt be a problem. The main functionality, honestly, not changed since original jb. Thats a shame. Thats why I cracking them like nuts





On the fourth day I taked a decision to make my own "OpenCobra" payload. only clean code without drm and garbage, to be able to port it to any new firmware, and change/add features. It taked 2 days, 3000 lines of asm, and you had seen the result.

Atm it based on 4.1 payload, plans for future is check/add new features from 4.4/5.0. Port to a new firmware (if cobra will not do this for me), and realize all nice innovations from new version of psp emu, such as better emu accuracy, 3D and etc...

In video you had seen Payload Loader. Thats the all code it has:

This tag related patches handled by mngr. So far I want to move it in payload. First I have to check how it handled in 4.4 / 5.0

Not sure yet when it will be released, if it will be, but we will see.

If this subject will be interested for people, maybe I will write a full article about True Blue / Cobra analysis and hacking.

btw: Me and ~ some psp mysterious dark figure ~ reverse engineered algo for generating valid psp isos back to jule. But saves and a lot of games dont work without patching. So cobra's patched emu much better there imho."

Below are some additional pics from his blog which simply states: Usercheat + Cobra = <3

From flat_z: Here is some explanations to make things more clearer. If you read my twit about ps2_netemu you can see that I reverse-engineered it. It includes almost all things which are required to make custom disc images of original PS2 discs and run them on the PS3 if everything will works fine. So it can lead us to the process of remastering PS2 discs which includes making of ISO.BIN.ENC (the encrypted version of original image which can be read by the PS3), creation and encryption of .VME files (virtual memory cards), ISO.BIN.EDAT (includes the title ID of disc).

The only thing which is not currently known is the format of decrypted CONFIG file (I can decrypt the file and encrypt it back but it have a complex format). It is optional and can be empty but I'm afraid that some games requires it to run on the PS3. My plan was the creation of PS2 remastering tool and I wanted to share it. Although I even not sure will it work or no but there are many chances that it will.

But something happened before I started to do it. My HDD on the laptop died and I have all information regarding PS3 on it. Although I was able to restore some important files but not all. So I need a time to buy components for a new computer and build it. For the same reason, I have a delay on my real job (I'm working as a free-lancer) so I will going to do my job before I start to do something new for PS3.

P.S. I see many questions about compatibility. You don't need a backward compatible PS3 console to run PS2 games through ps2_netemu because it is software emulator and doesn't require any PS2 hardware components. Also I think that ps2_netemu is more better and stable than ps2_softemu but this statement requires testing.

Finally, from naehrwert (via twitter.com/naehrwert) comes some related Cobra ODE EID0 information (ECDSA from pastie.org/6169158) , as follows:

While this is definitely interesting news, odds are it's just a ploy for the Cobra Team to release a new dongle that will be 'required' for their upcoming PS3 4.3x CFW unfortunately or the PS3 ODE in order to further line their pockets with PlayStation 3 sceners' hard-earned cash once again... as always, time will tell for sure.

I'm very surprised this hasn't been cloned yet!

I understand it's supposed to have some sort of on-board security, but since when has that stopped anyone

For those who own one, Cobra USB Firmware 3.1 is now released with the following changes:

Cobra Firmware 3.1 is out, minor release to fix bugs.

  • Fixed stability problems. Cobra users are advised to update to this firmware as soon as possible.
  • Fixed compatibility issue with Mortal Kombat.
  • Fixed PAL/NTSC issues in psx games.
  • Bugfix: some few specific psx titles such as Langrisser Final Edition wouldn't play in other regions.
  • Fixed a possible discless bug under very rare circumstances.
  • Cobra USB Manager can now understand the ".001, .002, ..." name convention used by hjsplit and other similar programs and rename them automatically to ".0, .1", name convention. Users can use hjsplit or any other similar tool to split iso files in the PC.
  • Added functionality to the core to implement a cobra firmware updater in the PS3.

As far as I know every PS3 model is capable of PSone emulation but not every model is PS2 backwards compatible.

Cobra USB however can enable PS2 emulation on every PS3.

Here is an update for Cobra USB users by johnnydoe of the Cobra USB v3.55 patched with Kmeaw features: ps3crunch.net/forum/threads/355-Cobra?p=3474#post3474

To quote: Hi everyone! i have patched the cobra firmware with the usual stuff like lv2 peek/poke etc both their core os files are patched so it should work with or without the dongle.

If you wanna unpack it and have a look or try it you can download it here: [Register or Login to view links]

From the ReadMe file: This is cobras 3.55 firmware patched with peak/poke for lv2 on both coreos files and the usual vsh/nas_plugin and install package file option.

Finally, confirmed by PS3 hacker Cyberskunk stating there: It is what it says it is but you would still need the dongle to use the cobra features. I have not installed it though..

I'm confused about this part. "Integrated support to play PS1 game ISO’s from HDD". Would this mean for backwards compatible PS3's on 3.55? I have one of the newer slims sadly lol.

Today the Cobra USB 3.0 Firmware Pack and 3.55 PS3 CFW is released, with details below from their site:

Download: [Register or Login to view links]


The Cobra Team is proud to present the Cobra 3.0 firmware pack, available from downloads section. In this release we enabled the Cobra USB device on 3.55 via use of our own cfw. Enjoy the release and look forward to many new features to come in future releases. Please be sure to read the updated user manual for detailed instructions on upgrading and usage!

  • Added compatibility with 3.55. Support for firmware 3.41 is discontinued, since now all updates will be for 3.55. In 3.55, Cobra keeps all the features of previous versions, adds the ones listed below and also removes some of the annoyances of the jailbreak exploit. Please, follow the steps in the manual, you must install first Cobra 3.55 cfw.

  • Added a new discless mode for PS3 backups in jailbreak format. This mode will be activated automatically when you load a backup and there is no disc inserted. In this mode, games are loaded from disc icon, not app_home, although app_home hack is still supported. This mode has a higher compatibility than the app_home hack, and smaller than discless PS3 isos.

  • Added support for PS2 backups in iso format to the remaining backwards compatible models (CECHA and CECHB).

  • PS2 isos can now be played discless too.

  • Fixed compatibility issue with GT5. If you still experience poroblems, please delete installed game data from XMB and try again.

Note: Cobra CFW will behave like a 3.55 ofw if the PS3 is booted without Cobra USB connected. It is useless to install this CFW if you don’t have a Cobra USB device.

Cobra USB requires certain binary files of the firmware not to be changed. Changing these files may make Cobra USB not to work at all, or to behave incorrectly. Changing fonts, xml, etc is fine, if the user knows what he is doing.

Its all very well people creating videos with homebrew icons in their xmb on 3.66 and going into psn, any fool can do that, but running homebrew is another matter.

Maybe a video of someone using homebrew 1st, then exiting back out to the xmb and then login to psn after would be nice.

Today Cobra USB has announced that 3.55 compatibility is coming next week, as follows:

We’re pleased to announce that development work is drawing to a close for our Cobra USB 3.55 solution. As previously announced, the new firmware pack will allow users running 3.55 cfw’s to install a new firmware console and dongle side which will enable use of the Cobra USB functionality, as well as allowing users to retain standard 3.55 cfw functionality.

Owing to testing and security implementation, the development cycle lasted a little longer than expected, but we are on track to release the new firmware pack sometime next week. Enjoy the new release and look forward to the next, there’s plenty more features and surprises on the way from the Cobra team...

Also below is a Cobra USB Manager Reskinning Guide from gliitch for those who own the dongle itself:

BEFORE:

s3nint3!s3nint3!s3nint3!
AFTER:
s3nint3!s3nint3!s3nint3!s3nint3!s3nint3!
Cobra USB Manager Reskinned Tutorial:

PART 1:

To make things easier please make sure that the following programs are installed before hand.

The pictures MUST be in 1920x1080 for this to work. A quick google will bring up aload of images in that resolution. If you have a picture that isn't in 1920x1080 you can create it with Infan View.

1: Once you have the picture you want, load up Watermark Image, this is where you'll be able to layer on top of the current image. Anyway, upload the picture you have chosen, untick "Resize Images" and "Use 3D depth map."

Where it says Output Format make put it up to 100, then change the output format to PNG. Click "File", you'll then be asked to upload the picture. Now click "Select Preview Image" This will bring up an image of the picture you have chosen.

IMPORTANT: If the picture is of the wrong resolution and not [1920x1080] the teplate will turn your picture black. Now, where it says "Image used for watermarking".

It is best to keep everything in one directory so you know where it is. On your computer navigate to the "Templates" directory, select "Template 1" and use that. So now you should have your chosen photo overlayed with the template you've just selected.

Once you've created the templates, you will need to rename them as

  • "back1.PNG"
  • "back2.PNG"
  • "back3.PNG"

Then FTP them into /dev_hdd0/game/CBUM01234/USRDIR/

Overwrite the exsisting files. Below is an explanation of whateach of the templates do.

Templates Explained:

Template 1:

  • X - Load
  • Square - Change mode [Games PS3 Blu-Ray DVD PSX PS2]
  • Circle - Copy
  • Triangle - Delete

Template 2:

  • X - OK, Circle - Cancel
  • Copies Disks to HDD

Template 3:

  • X - OK, Circle - Cancel
  • Settings

As I am a very avid fan of Final Fantasy VII and to show my appreciation, i've decided to go with a FFVII Based Skin. You can use your own images, but they need to be 1920x1080 also in full color. it's due to the manager itself the wording doesn't show up properly if you use a white or light based background ] We haven't found a way to change the fonts, or the colors used yet, but once we/ i have, this will be updated to reflect these changes.

PART 2: MAKING BACKGROUND & ICON

These 2 must be in PNG format, the Background should be in 1920x1080, which should be named PIC1. Any Icon can be used but it has to be name as ICON0

PART 3: MAKING THE BACKGROUND MUSIC & MAKING IT LOOP.

Now open up Audicity select the audio you would like to use [MP3] and drag the little finger icon across to where you'd like your music to finish. Go to "Edit" "Delete" so you are now left with a part you wish to use as your background music.

If you would like your music to fade out select the end, 3 seconds will do, and then go to effects and select fade out. Now go to "File" and "Export As MP3" you will need to install the lame_enc.dll file, which also be included in the pack.

Once this is done, fire up Goldwave, go to File and select "Save As" and select WAV. then scroll down and select ATRAC3 66kbs. Now click save.

Finally click on to GWAT.exe, drag and drop the pre-made X.wav file into it. Press "Goldwave" it will then say "X.wav looped" but it will save it as "Looped X.at3"

PART 4: USING PS3SFO EDIT TO CHANGE THE NAME OF THE MANAGER.

Fire up FTP on your PS3 and whatever program you use, to FTP into it. Go to the following directory /dev_hdd0/game/CBUM01234. (i'm not joking that is the cobra directory >_

I updated the first post with another video (also below) from DemonHades, with the following rough translation: demonhades.org/foro/viewtopic.php?t=4833&f=297
DH JFW entering the official Store

Nothing guys, as it has been speculated that it all was not true, that Thégra with JFW and DH are the really same as the other CFW, so here I leave a video with what we have and can do.

And thanks to everyone and especially for the video PS_Juan, sorry for chompy video because of rushing I took.

Soon the truth, only to see how the DH JFW while entering the store on 341 , and is dedicated to dospiedras pdnked EOL.





It appears to be in response to this "Dospiedra modified firmware" video by pdnked:

Rebug 3.66 CFW (Spanish) PUP: [Register or Login to view links] / [Register or Login to view links] (Mirror) / [Register or Login to view links] (Mirror #2)

Rough translation: Dospiedra modified firmware.

Details to note:

  • Only user-3.55 (no matter if CFW or OFW)
  • No turning back, pass over to 3.66 with all that that entails. Only you can downgrade to INFECTUS (dospiedras method).
  • No syscalls / payloads ... so that the burden of copies is disabled. For what is agreed is a firmware guy ... GeoHot.
  • The 3.55 homebrew installed no longer work.
  • There is no package installer (for now).
  • Full access to PSN.
  • Works on both Fat and Slim (as shown in the video), no tricks hardware and could suggest a user in the comments.

Of course, install under your own responsibility, nor do I Dospiedras not responsible for any errors or omissions performed by the user.
