Project: Cobra and True Blue PS3 Dongles, TB EBOOTs Examined


Sponsored Links
157w ago - As a follow-up on our previous article with the spirit of Operation: Mongoose in mind, we are continuing to examine both the Cobra and True Blue PS3 DRM-infected dongles and TB EBOOT files, and welcome any help with this project from other PlayStation 3 developers in the scene!

First let me tell you the following explanation is not a theory or any rumors, it's actually how the USB dongles work to allow different things.

We heard many rumors / theories about the process of the Cobra / True Blue but I didn't see anyone give any big answer about that (I'm not saying I would give you the big answer but the explanation how it works and how to make this possible)

Cobra / True Blue Part 1

Both dongle use syscall / payload (after a big investigation, both dongle also follow the work of graf_chokolo and the functionality of the dongle can be ported into a CFW (not a good idea from some devs I guess)

Cobra / True Blue use a lv1_wrapper (syscall implementation) that can allow to use subroutine function into kernel mode call. Following the dump of the Cobra / True Blue, every subroutine are indicated inside the dump (probably the reason of some clone like JB-King)

What all this mean ?

About the TB Eboot, i come back on what i said recently, the TB Eboot come from original Eboot (don't make any sense that they access to the dev server when have not Eboot on it) the PSN dev don't exist this way... but for related beta development games and testing beta multiplayer mode, interface beta test PSN for games etc... but nothing related to a Eboot.

TB use original Eboot and make their own sign (you can easily generate a new NPDRM sign with a Self/elf)

How can boot the games, the NPDRM Sign made in TB can't be run into a user mode, you would have a error of boot and every program that you resign etc... will not boot into a usermode... that's why we need to use a syscall that can let use into a kernel mode to execute a program that not recognized and authorized by the system. The dongle validates the actual eboot by syscall / subroutine.

For example, I want to have a execute something into the CoreOS but I'm not allowed because I can only execute this on a kernel mode, fine, I use my actual user mode to turn into a kernel mode by using a syscall.

A Syscall can allow you to execute, create, read, load, etc... The limitation of a dongle = the PS3 system, a dongle it's only here to prevent a error that by using redirection and syscall, the dongle give a correct answer that PS3 system execute.

If you check correctly the dump you can see 0x80 -> correspond to the C library, also when you call into kernel mode, the kernel fix the table permission that allow to give big access. You can recognized r1 stack register -> 0xA0 (debugger mode) -> R2 stack status...

Ok you probably gonna ask, what is that ? lol

It's actually a schema / plan from the dongle, the dongle is here to give a strong access to the system that you can execute what you want.

For example the PS2 Emu of Cobra = PS2 self (is not executed into a user mode but kernel mode / debugger mode that) reason why it can be execute under a PS3 Slim retail without following an error system.

How this can help ?

This mean many things, that you don't need any keys to execute under a kernel / debugger mode because anyway the syscall will give you a whole access to the cell execution.

I want to give a simply explanation that everybody can understand, the TB EBoot = Original Eboot from Original game, we not interested by the sce header, etc... we only want the elf header program represent and related to the game execution (like a exe, you patch the exe to be run without cd) here almost the same, we patch the elf with a fake sign can be run into a specific mode without asking anything.

What is weird, graf gave many oriented possibility and no one try to exploit them but only in a business way. Anyway like I said, the dongle is in relation with the PS3 system/Dev_Flash/Core_OS

I'm also working on it and try to do my best to release something strong and free... but my knowledge is limited and I can't do that alone.

Why I explain all that, it's because I want to see also some good dev can work on it with me, actually I want to thanks graf for all this awesome stuff, cfwprophet and all the PS3 scene that support us, I say also thanks to the people who insult me and said I'm a fake... more you said that and more I don't care and offer good stuff

Somebody said he want to be fame, no at all... I don't really care, my family and my gf give me already that by supporting me, it's enough

Anyway I would like this project to encourage PS3 homebrew developers to help out if they can, and also for the work that cfwprophet, me and others are doing on it will be updated here periodically.

PS: Probably go have more explanation and more stuff about it in the next week. Oh yes about the Debug PKG that is available on PSN Dev (it's not related to the TB Eboot)

You can make a Debug PKG yourself by only extracting the ELF, make a Self without NPDRM, leave him Eboot.self and make a PKG without NPDRM, this represent exactly what is a debug PKG (it's a standard Self inside a PKG without NPDRM)

Below is a True Blue Patch Viewer from Corwin75 via French site (games-hack.fr/index.php?threads/release-true-blue-patch-viewer.6580/) for those interested. Rough translation (from ps-addict.fr/forum/True-Blue-Patch-Viewer-File-Downloader-t6296.html):

It aims to list all Eboot.bin compatible with the True Blue Dongle and to make available patches created by the various Team direct download. It also incorporates the latest update of True Blue Dongle.

Our goal is to keep it updated constantly so that each new release of patch is integrated into the app. Here are the features:

  • 4 downloads allowed then a wait of an hour to re-download
  • Update the constant soft output of each new patch
  • Download the latest update for the dongle True Blue
  • Description and display screen of the patch
  • Direct download link

If you have any ideas or advice on improving the software contact us.

Finally, Guillaume17 has made available a True Blue Patch Downloader here ([Register or Login to view links]) and a version with the '4 downloads per hour limit restriction' removed is also available here: [Register or Login to view links]

Also has made available a partial decompiled source code of the application here: [Register or Login to view links]

This is where we need some kind of co-op with TB team and hotz. If reactpsn compatibility would be implemented in new TBCFW or dongle update, this would give us much more working space for fixing additional content.

My team sucessfully fixed several TB games DLCs with use of reactpsn. I hate use of reactpsn to play games. Fully fixed games are the way it should be. Some users don't have act.dat file for never loggin onto PSN and they are forced to use rebug. Rebug is not possible anymore with TB 2.5.

Even better option for us would be if TB team implements "peek and poke" in their CFW so we can fully fix games with help of reactpsn or ps3tools. Then the need for edited VSH.self for TB CFWv2 becomes unnecessary. If this is problematic for TB CFW stability or whatever, then some kind of "switch mode" should be available to enter "peek and poke mode" so we can do our thing and return to "normal payload mode" with DLC content fully fixed. Time to expand views.

Further more, releasing fixed update patches for TB games is necessary for all DLC content to work properly or to work at all. Releasing games with base content only if not enough anymore. Some games expand or get upgraded with DLC content. That's it from me.

True Blue dongle firmware v2.61 has been released. Changes include:

  • Added PS3 firmware version spoofer
  • Game compatibility fixes

Note: remember if you are on 2.51 or 2.6 already you will need to first reinstall the old v2 CFW v2.5 first and then install the 2.61 patch on top of that (as explained in the patch readme.txt)

payload spoofing doesn't work with a pre-patch vsh.self, it's possible they'll have to figure how to apply reAct patches through payload

2.6 is a spoofer 4.11 version, but no PSN access, obviously

Today the True Blue PS3 JB2 v2.6 followed by v2.51 (ReActPSN / Cinavia Remover / Rebug Spoofer bug fix) updates have been released.

24 - 4 - 2012

It has come to our attention that a small number of users may be affected by freezing at boot if using 2.6 dongle fw where they have modified their console cfw's files by installing programs such as ReactPSN, Cineavi protection remover or other such programs. The 2.6 dongle fw functions perfectly where the user has NOT carried out modifications to the console cfw. The console cfw should not be modified when running TB 2.51 cfw or 2.6 cfw, as this will cause incompatibilities which can lead to freezing at boot reported by a few users this evening on the forums.

In order to provide a feature rich experience for users we will add support for some popular programs/applications in TB CFW 2.61 which will be released within the coming days. We thank all TB users for their continued support and patience whilst we develop feature updates and firmwares.

Anyone who has modified their TB CFW and is experiencing freezing, may simply revert to 2.51 TB FW using the special fw file attached here and reinstall the 3.55 CFW DG on their console. This will compeletly fix any freezing issues. We kindly remind TB users not to modify the TB console CFW 3.55 unless we explicitly state in the accompanying notes included with upcoming TB 2.61 fw that the program/application is supported.

How to update:

1. Make sure your PS3 is running the True Blue "3.55-Dongle-DG" CFW (custom firmware)
2. Copy TrueBlueUpdate-2.51.pkg from this archive to a USB flash drive
3. Boot your PS3 _WITHOUT_ True Blue inserted, and then insert the USB flash drive
4. Navigate to (Game) -> (Install Package Files), and then select TrueBlueUpdate-2.51.pkg
5. The True Blue updater will be installed onto your PS3 HDD
6. Navigate to (Game) and load "True Blue Update v2.51"
7. The updater will start, and will then prompt you to insert the True Blue dongle. Insert it only at this point, and continue. Your dongle will then be updated
8. After the update procedure has completed your PS3 will reset, and you will then be able to enjoy your updated dongle
9. You may delete the True Blue Updater from your HDD after the update is complete

True Blue dongle firmware v2.6 has been released. Changes include:

Change log: - v2.6

  • Added PS3 firmware version spoofer
  • Game compatibility fixes

Change log: - v2.51

  • Added compatibility for revised True Blue hardware

ReActPSN on True Blue CFW v2, Update 2.61 (no previous PSN activation, no VSH mod) via ps3crunch.net/forum/threads/3353-reactPSN?p=38306#post38306 from PatrickBatman:

REACTPSN 2.0 or 2.2 install for true blue CFW v2 update 2.61 (No previous PSN purchase required the act.date file)

I havent tried to install reactPSN straight from 2.61 (you may need the VSH file route which is hazardous as you have to modify dev_blind)

1. Install TB CFW v2 and 2.51 or lower update if havent already.

2. Put your USB Thumb or USB HDD back into your PC or MAC.

3. Download both reActPSN v2.0 or 2.20 and Rebug Spoofer 4.00

4. Now extract reactPSN v2.0.rar (or 2.20) and drag reactPSN v2.0 pkg to the root of your USB Thumb stick or USB HDD, do the same for REbug Spoofer.pkg

5. On the root of your USB Thumb Stick create a folder called exdata. Whenever you get new rap and edat files drag them into this very folder (Every Time) usb:exdata/rap files. Always leave previous rap and edat files in exdata for when you reuse reActPSN v2.0 for newer games downloaded.

6. Now install the reActPSN v2.0 pkg and Rebug Spoofer like any other pkg from usb in furthest PS3 right USB port (but dont run the programs created yet)

7. Turn off PS3 and make sure that the True Blue Dongle is removed, Turn on PS3.

8. Run rebug Spoofer and spoof your ps3 (install files and activate spoofer, will reboot each time) check system info in XMB to make sure version is 4.00

9. Run ReActPSN and hold R1 (Some people say Hold Circle instead) during the restart process should only take about 20 seconds. (Holding R1 will make a ReActPSN folder on the base of your usb drive with 2 folders in it "BK0001" and "pubPSN"). Any content you purchased prior to this hack will be backed up in pubPSN folder in the form of rap and edat files (These are the very files needed for us all to activate any shared psn, dlc or psone classic games, THAT YOU OWN. If you had no previous content BK0001 wont be created).

10. Check to see if reactPSN folder was created on USB HD/STICK if not you didnt hold down R1 or USB HD is not in PS3 right port (cant use HUB at this point)

12. Copy the exdata folder contents in pubPSN to the exdata folder you created on the root of your USB drive.

13. Create a new user account on the PS3 called aa

14. Run reActPSN again *do not push anything this time (it will rename user "aa" to reActPSN v2.0 xrif xedat).

15. When it's finished your PS3 console will automatically restart again (If not restart PS3 manually).

16. You'll notice aa has been renamed to something reActPSN v2.0 xrif xedat. Thats it done.

17. Everytime you want to install new PSN , PSone games or DLC content, just go into reActPSN v2.0 ACCOUNT and rename it to aa (You can do multiple games, dlc, etc at one time, if you have rap and edat files, usb HD needs to be in PS3 right port when doing step 17, 18 & 19)

18. Download, extract rap and edat files (that came with dlc.pkg etc) to exdata folder on the root of your USB Thumb stick or USB HDD

19. Run reActPSN v2.0 (app) again, then install psn game, dlc, or psone classic pkg(s) after reboot.

20. Make sure to keep all previously activated rap and edat files in the exdata folder on Root of USB Thumb stick or HDD for everytime you use reActPSN v2.0 and also for archival purposes.

21. Plug in true blue dongle, start PS3, ReactPSN will now work for 2.51 and lower TB update Continue for 2.61 update.

22. Open rebug spoofer (app), and hit L1 + X that un spoofs (console reboots) it then go back to it and hit L1 + O that uninstalls the files (console reboots again)

23. Then update to 2.61. system info should read true blue 4.11, 2.61 (or something like that)

24. Run reactPSN (app) again, play game ("reactPSN" USB HD can now be plugged into hub if need be)

Hello, everybody! At the last time there was a lot noob news about loading TB lv2_kernel in IDA and what it really does, so I really wanted take a look at this by myself

This thing is really small, and took a few minutes for rce the "salt" of it. I spend more time writing some scripts for it

This is my clean idb [Register or Login to view links]
(I dont share my idb with comments, because its mostly Russian comments )

How you can see it uses some ofbusctaion, unconditionally branches, complex of instructions mtctr and bctrl.
When you will start reversing sub_80000000007F1114, the first thing what you will see that there is some condition of execution sub_80000000007F0F10.

Let's look this function, allocating a buffers already a good sign) You look subfunctions and see some crypt) sub_80000000007F0B1C is Tiny Encryption Algorithm
[CODE]
void decrypt (uint32_t* v, uint32_t* k) {
uint32_t v0=v[0], v1=v[1], sum=0xC6EF3720, i; /* set up */
uint32_t delta=0x9e3779b9; /* a key schedule constant */

will activate one of several effects at random intervals, such as erasing the internal PS3 HDD.


This scares me, not only will the PS3 HDD get formatted there might be some other effects for not using their dongle, who knows it might even update the PS3 to the latest firmware, or worse. Anyways for anyone with the clone do not attempt to update to 2.6 as of yet (just another remainder for those with any clones).
