November 3, 2012 // 4:34 pm - Following up on the Rebug 3.55.3 / 4.21.1 PS3 CFW REX Editions, this weekend PlayStation 3 developer deank has updated multiMAN to v04.10.00 which includes PS3 Rebug (REX) support alongside the changes outlined below.

Download: multiMAN v04.10.00 Base CEX (20121103) / multiMAN v04.10.00 Base CEX (20121103) (Mirror) / multiMAN v04.10.00 Base CEX (20121103) (Mirror #2) / multiMAN v04.10.00 Base CEX (20121103) (Mirror #3) / multiMAN v04.10.00 Base CEX (20121103) (Mirror #4) / multiMAN v04.10.00 Base CEX (20121103) (Mirror #5) / multiMAN v04.10.00 Base CEX (20121103) (Mirror #6) / multiMAN v04.10.00 Base CEX (20121103) (Mirror #7) / multiMAN v04.10.00 Base CEX (20121103) (Mirror #8) / multiMAN v04.10.00 Base CEX (20121103) (Mirror #9)

Below are the changes, as follows:


  • Added full support for 4.21REX (REBUG) firmware
  • Added support for 4.21REX in DEX full mode (DEX flash + DEX lv2 kernel)
  • Added support for PS1 disc backups for 4.21REX CFW in DEX/DEX mode
  • Added support for direct-disc-access for 4.21REX CFW in DEX/DEX mode (data CD/DVD/BD discs)
  • Added support for flashing 256MB NAND *.EID0.NANDBIN backups
  • Users with broken BD drives can use 4.21REX in DEX mode with fake BDEMU stick/image for 100% game compatibility

IMPORTANT NOTE: If you're using DEX mode in 4.21REX, use this CEX version of mM (do not install the reguar DEX mM which is only for official dex firmwares).

This package also includes:

  • Rebug Toolbox 02.00.00
  • c2d + openssl


It is to help users with broken BD-ROM drives (which have a working logic board and married to the PS3). A lot of games have issues when started from /app_home or using "Direct Boot", that's why this is the BEST solution for such users. You will have to be on 4.21CFW REBUG (REX) with DEX Target ID flash and DEX LV2 Kernel (full DEX MODE).

From the ReadMe file: If you do not want to waste a whole USB HDD you can use a small 512MB USB STICK to emulate your broken BD-ROM.


  • PC and PS3
  • USB stick/drive (512MB minimum size)
  • Disc Image Generator Software (ps3gen)
  • PLAYSTATION3.iso Dummy BDEMU image
  • 4.21CFW REBUG (REX) operating in DEX mode with DEX lv2_kernel (FULL DEX MODE)
  • Connect a USB HDD to be used for BDEMU
  • Start "Disc Image Generator for Playstation3" (ps3gen)
  • Click "Show" button in the top right-hand corner
  • Click "Select File..." button
  • Locate and select "PLAYSTATION3.iso" provided in this archive
  • Click "Save / Emu ..." button
  • Select "Write Image to BD Emulator HDD"
  • Select your BDEMU USB HDD
  • Pick a slot from the list and click "Write Image"

On your PS3 with 4.21REX CFW and multiMAN 04.10.00 installed:

  • Install "Rebug Toolbox 02.00.00" and launch it
  • In DEX/CEX: Flash your DEX EID0 NOR/NAND file (DEX-FLASH.EID0.NORBIN or DEX-FLASH.EID0.NANDBIN file on /dev_usb000 stick)
  • Quit Toolbox and reboot your PS3
  • In XMB "Settings" go to "Debug Settings" and set "Blu-ray Disc Access" option to "BD Emulator (USB)"
  • Turn off your PS3
  • Connect the BDEMU USB HDD drive/stick to the right-most port (/dev_usb000) - the port closest to the BD-ROM drive
  • Turn on your PS3
  • You should see "PLAYSTATION(R)3" Game Disc mounted in XMB Game column
  • Start multiMAN 04.10.00+, load a game from internal HDD or external USB HDD connected to another port. Do not unplug the BDEMU USB drive.
  • Start your game from the Disc Icon in XMB.

Done. In the pictures below you can see how it looks when you boot your PS3 with the dummy disc game, if you start it and if you mount a game with mM (Assassin's Creed III used as example) and check XMB

MultiMAN v04.10.00 is Now Updated with PS3 Rebug (REX) Support

The dongle won't work on OFW. It can be used to put the PS3 into FSM though.

Since 2 years ago, the source code was released for the Cobra USB dongle, and developers created COBRA 7.00 (unofficial) Released & Implemented into Rogero 4.46 v1.00, and since them many Cobra CFW have been developed with no dongle being needed.

I merged your post into our ongoing thread, and to answer your question all the related files can also be found within it but to save some time searching here is a link to all of the attached files of this thread:

This is the last news from their site as well:

Based on that, chances are if they plan to push new products they will probably renew their domain or get the site back online soon anyway.

Unfortunately, no CFW possible for CECH-3000 and up (and CECH-2500 with 3.60 stock), only ODE.

17 - 9 - 2015: Team Cobra is proud to present the next generation of ODE, the 5.10C.

Compatible with 25xx, 3xxx and 4xxx series consoles to 4.65 OFW. The 5.10C has inbuilt DMC (Drive Motor Controller) circuitry. We have greatly reduced the size of the PCB, with many optimizations in terms of components used. We are now running our own SATA core which allows for further speed increases and much more flexibility.

We have also worked hard to pass on the component cost savings to the end user, so you can expect a lower RRP from retailers. In short, the Cobra 5.10C ODE is much more compact, Flexible and faster design at a lower price!

We expect to start shipping soon, during October. Please reserve your 5.10C in advance by pre-ordering through Cobra resellers.

I don't think there is as classics need full CFW and ode is just emulating physical bd drive, better/cheaper option would be getting second hand ps2 and using ESR with FMCB, or getting fat model and adding network adaptor + installing hdd

hello guys.. just wanted to ask if there's anyway to play a ps2 classic on a cobra ode?

i downloaded fatal frame 2 ps2 classic and GOD HAND from PSN stuff along with its rap... if i tried to resign edat file within each game like i did with most of my ps1 games that downloaded from psn stuff will it work?

and if not is there anyway to make it work? i have Superslim 4.53 cobra MCU 2.2

i tried the resigning way with all of ps1 games and it worked awesome without any use of fix or crack so hoping for a ps2 too

Hi All,

I'm new to PS3 and this forum.

I purchased a PS3 CECH-4208A PS3 (12GB) OFW 4.55 and installed Cobra ODE 5.30A. Red LED is glowing when i power on PS3 and I dont see any cobra ode manager in PS3.

I did only hardware install. do i need to do anything from software end?

I formatted pen drive in NTFS format and created folders as per the guide still no good

Please advice.
