176w ago - As a follow-up to the initial news on JFW DH PS3 CFW, today [Register or Login to view links] has shared a video alongside some details via [Register or Login to view links] of their upcoming JFW DH PlayStation 3 Custom Firmware in action.

To quote, roughly translated: Here is how we are editing categories and relocating to give it more content and content management deployments. It really is not no big deal, but that you may know the new categories that would incorporate this new Custom.

First before anything we want to clarify that this thread is dedicated to community members and therefore DHorg the comments made about what this information is or is no longer cause is nothing more than mere envy, oppression, or that are to dispute. For outside the dates of publication and that are linked to circumstances that can slow or speed up the publication.

We will inform you as the evolution of DH JFW and what their news, which I will quote them below: [Register or Login to view links]

Cobra Payload as JFW DH Plugin

  • At the moment due to problems outside the scene Jaicrab the development of this plugin been in a paused state

New Linux Item

  • The JFW DH was gonna be no less, that includes 2 options to use Linux back in the console, in this regard are:
  • Install
  • Boot

Preloader, Recovery Boot - The JFW DH includes a preloader that is responsible for:

  • Back of the 3 RAW Flash to external media (USB)
  • Flashing copies from an external drive (usb).
  • Update the Preloader
  • Home of the flash write access (not necessarily more alejandro or substitutes)
  • The advantages are not required reinstalling all the PUP (from hardware checks) do not need to do: composite or go through the recovery

Services Packs

  • These packs include the basics in order to use plugins, loaders, ftp, etc.

Compatibility with Games and Applications

  • JFW DH uses a 341v2 core, this does not mean not being able to play all over now without patching.
  • The JFW DH is compatible with games that include between 3.56 down, including the current patched to 3.55
  • JFW DH runs natively games until 3.56 (original disks) without having to upgrade.
  • PSN games that require npdrm 356, are also supported without upgrading (the current cfw not give this support)
  • No need for a valid signature on the executable
  • Not going to make a port to 3.55 of this JFW DH, since it includes much more than himself 3.55

Members of the Project

  • Alejandro (special collaboration) = Central Core, security, preloader
  • Jaicrab = Core, central TheGrid, linux
  • DemonHades = xmb Categories, Organization, Implementations
  • DanteHades = Graphic Design, Theme
  • PS_Juan = Remodeling Categorie, Tester
  • Ing_pereira = Manager Creation, TheGrid
  • Borrego = Tester
  • Davje = documentation Editor
  • PSmaniaco = tester and contributor

1saludo and patience that good is worth waiting.

A short summary of JFW DH: State of the CFW from the translation details above:

  • Core 100%
  • Payload Cobra 50%
  • Linux 90%
  • Preloader 90%
  • Categories XMB 90%
  • 0% Managers
  • TheGrid 90%
  • Service Packs 0%

Preloader: The preloader can:

  • Flash dump the 3 partitions on an external (USB)
  • Restore partitions Flash via a dump on external media (USB)
  • Mounting partitions Flash write
  • The preloader can be updated.

TheGrid: TheGrid is a new category that includes a plugin manager, service packs, but also the name of the loader plugins. The plugins can launch tasks in the background.

Various details:

  • JFW The DH is based on the Firmware 3.41 v2 but is fully compatible with games requiring firmware 3.56 and earlier (3.55 patched games included).
  • Game discs that require firmware 3.56 or earlier without having to spend to update the console.
  • The PSN games that require a compatible NPDRM 3.56 without updating.
  • Executables do not need to be signed.

And the video of JFW DH: The video shows the personal side with a CFW Coldboot / Soundboot changed and a new category "RetroLaunch" Minis are supported and saves them (PS1/PS2 games and their backups will also be part of this category).

Those who wondered what the icon is black "JaiCraB", it must match the Firm USB Loader. DemonHades invites us to participate in their topic in order to advance the project as still no publication date.

I'm just hoping I can still use this dongle for something in the future instead of holding the door open with it. I'm wondering if I can flash it with Cobras firmware or can I flash it to use as a FSM dongle?

This OpenCobra payload sounds great, lets hope it can work with Rebug or other CFW firmwares.

Agreed, and sadly it's amazing how many people don't catch on to this recurring pattern through the years either

Max Louarn and Paul Owen have Gary Wayne Bowser (aka GaryOPA) plug a product on his Divineo / Xecuter funded domains, cash in on it for several months from unsuspecting PS3 scene users, then it fades to black after an alias (ie NoDRM, etc) mysteriously cracks it and releases patches and so on to make it work without needing to buy their 'disposable' product any longer... ironically just in time for their next endeavor to get underway, rinse and repeat all over (they forget to wash, dirty gits )

Its amazing they have been able to get away with this con job so long, but I guess when they buy up scene devs in the process (ie deank, who to this day denies it only fooling himself LOL ) it ensures they have a constant influx of users to keep their customer base stocked and ready to plug new 'disposable' products again to. Welcome to the PlayStation 3 scene!

who gives a crap about ode ? lol wtf.

this is not worthless... long as rogero or rebug can make a cfw with cobra built-in this will be pretty damn cool.

looking foward to it.

useless to crack it now, because cobra will be releasing ODE and TB was RIP.

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.

Keys!

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 = data, 0x38, 1);
_hexdump(" ECDSA R ", 0x38, s->R, 0x14, 1);
_hexdump(" ECDSA S ", 0x4C, s->S, 0x14, 1);
_hexdump(" ECDSA PUB", 0x60, s->pub, 0x28, 1);
_hexdump(" UNK ", 0x88, s->unk, 0x20, 1);
_hexdump(" OMAC ", 0xA8, s->omac, 0x10, 1);
_hexdump(" PADDING ", 0xB8, s->padding, 0x08, 1);
printf("\n");
}

/*!
* \brief Verify section.
* \param s Section.
* \param c Curve.
* \return Verify result.
*/
int verify_section(section_t *s, curve_t *c)
{
u8 hash[0x14];
u8 _R[21] = {0}, _S[21] = {0};

memcpy(_R + 1, s->R, 20);
memcpy(_S + 1, s->S, 20);

sha1(s->data, 0x38, hash);
ecdsa_set_curve(c->p, c->a, c->b, c->N, c->Gx, c->Gy);
ecdsa_set_pub(s->pub);
return ecdsa_verify(hash, _R, _S);
}

//Maybe you're lucky?!
int main()
{
dump_section("0_1", (section_t *)section0_1);
dump_section("0_2", (section_t *)section0_2);
printf("sig. 1 verified: %s\n", verify_section((section_t *)section0_1, (curve_t *)curve0) ? "yay" : "nay");
printf("sig. 2 verified: %s\n", verify_section((section_t *)section0_2, (curve_t *)curve0) ? "yay" : "nay");
printf("R_1 == R_2: %s\n", memcmp(((section_t *)section0_1)->R, ((section_t *)section0_2)->R, 0x14) ? "nay " : "yay ");
getchar();
return 0;
}[/code] 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.
