JaicraB on Cobra USB JIG Protection RTOC Trick for PS3


Sponsored Links
157w ago - Today Spanish PlayStation 3 developer JaicraB has explained the Cobra USB JIG protection RTOC trick implemented for the PS3 against cloning the device.

To quote, roughly translated: Flynn sent me this text explaining this protective carrying the Cobra, I hope it will open the eyes of those interested in reversing the dumps.

EXPLAIN RTOC COBRA TRICK

The JIG Cobra has several protective measures to ensure that your code could not be used correctly even if your code could be dumped.

This trick RTOC in the registry is the first used for this purpose in addition to hinder analysis.
Registration is initially RTOC stored in the battery to keep the RTOC of lv2 and power it back later:


At this point we have to explain that the OFFSET DELTA. DELTA OFFSET is a method used in the x86 in its original moments in the creation of computer viruses, to calculate the memory address in which we are in the sea of ​​bytes in RAM.

In the original time a computer virus when I did not know where he was pulled into an executable,
depending on the executable it could be an initial site or another, for it was invented DELTA OFFSET.

DELTA OFFSET can be used in any system, the procedure is:

  • Using the record that indicates the current execution address (or the next depending on the system)
  • Reducing the size of the previous code we use the value obtained from the registry.

Knowing this, and taking for example the x86 processor where the EIP register can not be read directly invented the trick make a call to a "subfunction" which is simply the following line to the call:


X86 call instruction saves the top of the stack the address of the next instruction to itself. Thus using pop draw from the top of the stack this value, and stored in eax for example, and having the memory address where we only subtract the above would be missing and we have the exact calculation.

The PowerPC can use this trick using the BL instruction is equivalent (LINK BRANCH), which jumps to a "subfunction" but before you save LR in the record the following address to BL.


At this point we see the trick used for the creation of the RTOC of charges at this time. If you look both r0 and RTOC are passed to 0:


Subsequently, given the value 0x11DE0 to RTOC:


A r0 is given the value 0x920:


R0 is subtracted from the value of RTOC:


Unlike the PowerPC x86 LR register can be read directly with mflr instruction, we put in RTOC the value obtained by the delta offset:


To calculate the delta offset subtract final instructions executed before the delta offset, which were 4, or 16 bytes:


Finally we add the value of r0 at the end of the delta offset RTOC, storing the result in the RTOC and this already takes RTOC suitable for this hook:


It takes having the RTOC stored in the stack 3 arguments that the hook received:


You call the function of the charges where the first argument will check for command 0x8202 (a special command to the usual):


After making the necessary steps as charged, the battery recovers the original RTOC, like the arguments the hook received, it executes the original instruction that was overwritten in the syscall entry 379 (in this case) to have our hook, and call the original syscall lv2:


Upon returning to retrieve the original LR from the stack and returns to the prompt

Below is multiMAN ver 04.53.04 BASE CEX (20131224) by deank and Cobra CFW Tools v1.27 by bitsbubba with details as follows:

Download: [Register or Login to view links] (43.83 MB) / [Register or Login to view links] (123.05 MB)

A lot of changes and additions to the last 04.53.03 so I decided it is better to have it with different version.

multiMAN 04.53.04:

  • Names of local PS3 games in ISO format are properly displayed (from PARAM.SFO)
  • Names of network and NTFS PS3 games in ISO format are properly displayed (from PARAM.SFO) after you load them at least once
  • PS3 ISO games from NTFS drives will now show background and cover (if loaded at least once)
  • Added support for checking for game updates for network and NTFS PS3 games in ISO format
  • Last loaded game/video (no network/ntfs) will be passed to webMAN for auto-load at next system start (making lastGAME almost obsolete)
  • While scanning for content, mmCM will prepare data for webMAN, too (NTFS info, images and param.sfo)
  • Upon launch, mM/mmCM will rescan your games and will cache images and other files
  • Small change to make mM "title_id" independent (in case you change it from the default BLES80608)
  • Downloading mM/mmCM updates is now "title"/"name" independent
  • In mmCM mode in HOME column you now have "Scan connected NTFS USB drives" option. In case you didn't connect the drive before launching mmCM you can use this option to refresh content from NTFS drives.

The update is available online as always within mM and in the WEB column.

If you wish to FORCE mM/mmCM to download the update just start mM/mmCM while holding L2+R2 and it will enter debug mode (reporting 04.53.DD for mM and 04.53.CD for mmCM). Then you can update from the HOME column.

Hi Guys! Sorry for the bad english, im Brazilian and I have a big problem.. Actually I play my ps3 on a 42" HDTV 1080p, but this TV isn't on my bedroom, I buy a Dell 19" DVI 1080i (1440x900) monitor, and adapted a DVI to HDMI on my monitor, making the correct connections the PS3 finally starts and the image of menus and options appear on the screen

Buuut, when I start multiman to run GTA V, the black screen appears and i can ear the sound of game, but without image (I used the RCA cable to out audio in a headset). This problem apply too to another games, when I start a PSN games, the black screen turn to appear.

Details: I use a HDMI gold cable, PS3 Fat, CFW Rogero 4.46
Resume: In the HDMI 1080p I can play, in HDMI-DVI 1080i I can see the menus and options, but i cant play... HELP!

Today Deank Kasabow (aka deank) released the latest version 04.53.00 followed by 04.53.01 and 04.53.02 of multiMAN including just the payload.

Download: multiMAN 04.53.00 (CEX) / [Register or Login to view links] / [Register or Login to view links] / [Register or Login to view links] (Mirror) / [Register or Login to view links] (Mirror) / [Register or Login to view links] (Mirror) / [Register or Login to view links] (Mirror) / [Register or Login to view links]

Nothing new, only the addition of the payload which allows booting and loading games on Custom Firmware base 4.53.

Changelog:

  • Added firmware payload 4.53 (added support for 4.53 CFW).

I have no intention of installing 4.53 at the moment, so hopefully folks will post back if it works properly.

Update: multiMAN 04.53.01 is now available (online update within mM and in the WEB column):

  • Added support for 4.53 CEX CFW (tested)
  • Fixed covers/backgrounds for network PS3 games in JB/folder format
  • Added spoof to version 4.53 (COBRA7 firmwares only)

On Cobra7 compatible firmwares - make sure to delete mM's USRDIR/cache folder (if you want to get PIC1.PNG covers for network JB/folder games).

Network (/net_host#/***PS3***/) games now show ICON0.PNG, PIC1.PNG and a cover if available.

Cobra Cinavia Tools for Rogero 4.46 Cobra v7.00 CFW by atreyu187

Download: Cobra_Cinavia_Tools.zip

Here is a simple set of files to remove Cinavia from Rogero 4.46 Cobra v7.00 CFW. This release comes with an install and un-install set of tools. Simply extract and choose the zip file in the folder you want.

Then copy the zip to a USB flash drive and double click on the file in mMOS and it will install or remove the patches of your choice. Tested on Rogero 4.46 Cobra v7.00 as Habib already has this disabled.

I will be adding some more Cobra packs like a nice updated plugin pack with PSNPatch, users new peek/poke, and webMAN 1.25 to replace my older pack with AUTOBOOT.ISO for Fan Control since deank has implemented this already.

UPDATE for Cobra Cinavia BD Disable

Ok now I have added Habib's BD Cinavia removal as well. Now this seems to be hit or miss for disc but it has worked for me on a copy of Smurfs 2 I dumped myself and made. It has some other stuff in there as well because it is a plugin and if you install just this it would disable all your other plugins. So as of 12/21/2013 this has the latest and great of each of the following plugins that will be installed.

  • webMAN 1.26 (Update # 2)
  • Habib's BD Cinavia Bypass
  • PSNPatch v1.06

It will install all plugins to hdd0:/plugins and replace your boot_plugins.txt file. You might want to remove your plugins from hdd0:/ root but is not needed. It will also install a new folder called on hdd0:/ called hdd0:/selfs

It contains prepNTFS.v1.01.self so you can execute it without having the app installed to prep NTFS drives via multiMAN OS with a simple press of the X button to prep your HDD. The last thing it will do is alphabatize your game section of your XMB if you don't have this neat little hack done already instead of them showing by date installed by Bahamut Lord.

If you want to remove any of these features simply extract the contents of the zip file delete what you want removed (nothing really should need to be done as they are all great features and this will stop any conflicts with this one tiny zip file) anyhow once removed zip all the folders backup and rename properly.

Download: [Register or Login to view links] (PS3~dev_hdd0.zip)

I also updated my Cinavia 4.46 removal pack to also update your CA.CER files to 4.53 files for good measure as another users requested this. Not a needed update and bitsbubba's tool set does this as well so it is here if you are interested is all but again not needed and nothing has changed with the actual Cinavia removal just updating the CA.CER files for online use to help mask your online status. Figured it would be good to add since I have added PSNPatch as well to help you stay hidden from the Giant Enemy Crab S*O*N*Y I hope you all enjoy.

Download: [Register or Login to view links] (PS3~dev_blind.zip)

Install as usual, place the zip file(s) on a HDD/USB drive and go into multiMAN OS and simply press X on each file to install. Then simply reboot and enjoy!!

For those interested I will be working on my PSN PKG to PS3 ISO (without need for rap/edat/reActPSN) tutorial tonight and tomorrow and have it ready by Monday at the very latest.

Also I did not write any of these tools, I only put them together for easy install for you all. Thanks for this goes out to KW, BahumatLord, Habib, bitsbubba & deank for all there work and giving me the ability to share these with you all. Without them this would not have been possible.

Update #2: From deank: I compiled showtime 4.3.582 for mM... It is available in the WEB column of multiMAN and also from the VIDEO column -> Update. Standalone versions are in the web column.

Download: [Register or Login to view links] / [Register or Login to view links]

Update #3: MultiMAN ver 04.53.02 BASE CEX is now available with the changes below, as follows:

04.53.02 (20131217)

  • Added proper detection of COBRA7 firmwares (4.46-4.53)
  • Added "Check for updates" for local PS3 games in ISO format
  • Added check when loading local/network PS3 games in ISO format if installed game update requires higher firmware version and fixes sprx/self/eboot files

Update #4: multiMAN ver 04.53.02 BASE CEX DEX STEALTH (20131219).zip (122.41 MB)

Download: multiMAN ver 04.53.02 BASE CEX DEX STEALTH (20131219)
