Following their PS3 IDPS Dumper v0.2.3 for 4.82 OFW update, the PS3Xploit Team of @bguerville@esc0rtd3w@smhabib and W released both a PlayStation 3 NOR / NAND Software Flash Writer and NOR Dumper to downgrade consoles without the need of a hardware flasher allowing those on Official Firmware (OFW) 4.82 to install Custom Firmware (CFW) finally.

To quote from STLcardsWS on the releases: Since this exploit is executed from 4.82 OFW, you can only install to a 4.82 CFW, HOWEVER if you wish to use an earlier firmware such as REBUG 4.81 for example, once on 4.82 CFW you must TOGGLE QA using a toggle tool, which allows CFW user’s to freely switch CFW version from past and present.

Flash Writer Compatible with these PS3 Models:

  • Supports FAT Models Axx/Bxx/Cxx/Exx/Gxx/Hxx/Jxx/Kxx/Lxx/Mxx/Pxx/Qxx
  • Supports SLIM Models 2xxx (minver 3.56 or lower ONLY, check with minverchk.pup)

PS3 OFW 4.82 NAND/NOR FLASH WRITER v1.0

:alert: Important — AVOIDING A BRICK

  • Verify flsh.hex file on a flash drive and in the far right USB slot!
    • 4.82 flsh.hex MD5: 8E156C99101BF36EC3EDB832982AE46D
  • DO NOT USE ON CFW (Custom Firmware) (Only Supports OFW)
  • DO NOT USE ON PS3 Models 3xxx/4xxx (aka SuperSlims / Late Slim models) you will brick those console.

:stop: As noted by esc0rtd3wYOU NEED TO BE ON OFW 4.82 TO USE WRITER….PERIOD! DO NOT DO THIS!!!!!!!!!!!!!

  • DO NOT RENAME THE flsh.hex FILE!!!!
  • VERIFY THE MD5 WHILE THE FILE IS ON THE USB STICK BEFORE PROCEEDING!!!
  • VERIFY THE USB STICK SHOWS UP UNDER XMB

PLEASE READ FIRST:

  • It’s essential not to flood the browser memory with junk before running the exploit. The reason for this is that due to javascript core memory usage limitations we are scanning several times a small range of browser memory (a few Mb) to find some essential data in RAM, if the memory is flooded then the range to scan becomes much larger & the probabilities that our data is found in the smaller range decrease dramatically..
  • So in short, never use the browser or set a homepage you cancel before running the exploit!
  • If you need to, set the homepage to ‘blank’, close the browser then reopen it to start the flash writer.

v1.0.0 – Initial Release

  • Supports Direct OFW to CFW patching for All Phat and 2xxx Slim (minver 3.56 Dec 2010 and lower)
  • the NOR/NAND writer will just copy 3Mb of CoreOS data to both ros0 & ros1 in the flash memory.
  • There is only one version released for 4.82. The same hex patch file can be used on nor & nand.
  • It’s as safe as possible, with a check for usb device & patch file making the exploit hang instead of corrupting flash if file is not found.
  • In case of corruption (extremely rare but could always happen), it’s only a partial brick because no per console info ever gets erased so a hardware flasher could still be used if ever a recovery reboot was impossible.

Usage Tips:

1) Try using a LAN connection or a solid WiFi connection during exploitation. A weak signal can cause problems.
2) If the exploit takes more than 5 minutes to work, reload page, browser, or restart console and try again.
3) If you are using a LAN connection and experience network issues, make sure all cables to router are in working order.

Steps:

1. Setup a small Web server on pc or smartphone. A custom miniweb application has been created by Aldo, and supplied to host files if you would like to use it. Don’t come to us for explanations about how to run a http server though. Google it.

2. Extract the files from release to your http server root folder.

3. Copy the “flsh.hex” file from release folder to root of flash drive.

4. Put a FAT32 USB key in port closest to BD Drive (/dev_usb000).

5. DOUBLE-CHECK your flash drive on XMB to make sure it shows up under Music, Photos, Videos, etc.

6. Open the PS3 browser File Address window, write the IP address of your server (and the port if not 80) & press the Start button.

7. Select the appropriate button for your console and wait for PS3 to power down. DO NOT STOP THE PROCESS ONCE STARTED!!

8. Once PS3 has powered down, reboot console and install CFW matching OFW version. If installing through XMB does not work, boot to recovery and install.

THE CORRECT FIRMWARE VERSION BETWEEN 4.81 and 4.82 IS AUTOMATICALLY SELECTED!

PLEASE READ FIRST:

v1.0.0 – Initial Release. 

  • Supports Dumping NOR on both 4.81 & 4.82.
  • bguerville tried to produce a release that was easy to port & he succeeded. Anyone able to search for offsets in IDA can add support to any firmware version in the dumper in a matter of minutes.
  • For technical reasons, the Full NAND dumper release is postponed. We will now be focusing on self execution & if we succeed there will be no need for the extra ROP work to do the NAND dumper. If we fail, I will finish it in ROP.
  • The dumper will be released in a form extremely easy to port so others can tweak it to their heart content with outcomes having to face complicated searches in the big unicode strings
  • A lot of time has been invested into making the javascript + UI more efficient, as well as the trigger phase faster & more stable. I hope you enjoy the result.

5. Open the PS3 browser File Address window, write the IP address of your server (and the port if not 80) & press the Start button.

6. The dumper will detect the firmware version of your console automatically & setup the code appropriately so there is only one version for both 4.81 & 4.82. Run until ps3 beeps & shutdown. The flash dump should be a 16MB file on your USB drive as dump.hex.

:arrow: Frequently Asked Questions & Additional Notes

Will this jailbreak my SuperSlim?

  • NO, (PS3Xploit has strong possibility to eventually evolve into a HEN style exploit (that aspect will take some additional development and time, at this time PS3Xploit exploit has not evolved enough)

Can in install a CFW before 4.82, such as Rebug 4.81 or an earlier CFW?

  • Yes, however you must Toggle QA Flag. Once the Token is activated you have the ability to then freely jump CFW versions. (see below for details)

How do I Toggle QA Flag?

  • When on a CFW download & install QA TOGGLER (Standalone) (Note: Will just show a black screen then reboot the PS3)

How do I know for sure if my PS3 Model is compatible ?

  • You must have a PS3 Console that has a Factory Firmware of 3.56 and below.
  • To check, its easy with this simple tool for OFW, Download minverchk.rar
  • Then place the .pup file on a FAT32 USB Flash Drive in a PS3/UPDATE folder (create path if needed)
  • Now on the PS3 XMB goto Setting ->> System Update >>> Update via Media Storage
  • Once shown on the list select the PUP and install, shortly after there will be a message showing the factory firmware the console was shipped,
  • For this we want 3.56 and below.
  • ANYTHING HIGHER THEN 3.56 IS NOT ABLE INSTALL A CFW. Sorry this will not work for your console, but there could be a HEN (Homebrew Enabler) possible for running homebrew, but additional research and time is needed for achievement, additional details can be read here.

Finally, from Red to quote: In case anyone is too lazy to host the files themselves I threw the files on my webserver if you would prefer to use it

Of course great job to the team that created this. Im going to start playing with it now! What a way to end Thanksgiving day!

There’s also a brief tutorial by LightningMods and a PS3 CFW on Latest OFW 4.82 Guide by Zer0xFF available, and ask any questions in the comments below if you get stuck and need additional help.
