PS3 CFW 4.82

I am trying to use my PS3 today and it seems that my son had accidentally upgrade the firmware to the latest Official Firmware 4.82. Prior to this I am having CFW 4.55 and I haven’t upgrade it cause all the games are still working. so ARRGGGHH!!!

Keep Calm and search google, so I stumble across some fine instruction to flash back the my PS3 CFW 4.82. I use the following link for the instruction

The exploit tools patch can be found in the following location.

To obtain the legit information after being con from few other various sites with firmware that was password protected and trying to get you to sign up for survey or something similar and selling your email address, mobile phone number and the like.

The Custom firmware should be obtained from the following.

REBUG_4.82.1_LITE_c5da00d59e4d1a7aa599e5d0e21415f8 _PS3UPDAT.PUP

I am patiently waiting for the exploit to work its magic, this is the second try and it still not successful.

After gazillion tries, the following steps is the one that is successful.

Use the HDD method instead of USB & follow each of these steps to the letter:

A) Flash NOR
It’s highly recommended to install the 4.82 official firmware twice on your console before using ps3xploit flash writer v2.0.
If your ps3 is already on ofw 4.82 then just install the 4.82 system update PUP again.

Once done, open your ps3 browser, set the homepage to
Restart the browser.
Follow the on screen instructions ie
1. download the flash_482.jpg file
2. initialize exploitation
3. patch flash

When patching is finished, you should get a success message.
To protect your console against any risk of bricking, do NOT turn off or reboot the console just yet, you should validate the Flash memory first.

B) Dump NOR
Now set your homepage to
Restart your browser.
Follow the on screen instructions ie
1. download the dump.jpg file
2. initialize exploitation
3. dump nor flash

When the dump is done you should get a success message.

C) Validate NOR
Insert a fat32 USB key in ps3.
Go to the Photo colum on XMB, select the dump.jpg file & press the Triangle button. Choose to copy the file to USB device.
On PC, rename the file to dump.hex & use PyPS3checker tool to validate the dump.
You can get this tool from the dev’s github repo:
Read PyPS3checker_README.txt for tool requirements & usage syntax. You will need to install python 2.7.15, the installer is available for download on

In the PyPS3checker validation result screen, if you get either ros0 or ros1 valid with PS3Xploit 4.82 then the patch was successful, you can reboot & install the 4.82 cfw of your choosing. ;)
If the dump isn’t validated, ie you get more than 1 ros warning, do not switch off your console & post here to get further guidance.

Hope it helps.

Upgrade PS3 3.55 KMeaw to 4.55 Rogero

It’s about time to update my PS3 with from 3.55 to 4.55, so here are the steps.

Tools We’ll Need:

  1. 1 USB thumb drive (FAT32 formatted)
  2. WinRAR (official site)
  3. Rebug Toolbox (official site) (my download)
  4. eID_Root_Key Dumper (official site) (my download)
  5. 4.55 Rogero Update (official site) (my download)
  6. MultiMan (official site) (my download)


  • CEX – Customer bought PS3 (from BestBuy, Target, Amazon, etc.)
  • DEX – Developer edition PS3 (NOT bought in a retail store)
  • CFW – Custom Firmware
  • OFW – Original Firmware (directly from Sony)
  • MFW – Modified Firmware (usually interchangeable with CFW)

USB Prep-Work:

  1. Download Rogero 4.55, MultiMan,  eID_Dumper, and Redbug Toolbox from any of the above links
  2. Insert USB stick into computer
  3. On USB Stick, create folder called “PS3″
  4. Inside PS3 folder create folder called “UPDATE”
  5. Open Rogero archive (.RAR file) and drag the .PUP file to the Update folder; close archive when done
  6. On your PC, rename the file to “PS3UPDAT.pup”
  7. Open Multiman archive and extract .pkg file to root of USB Stick (which means don’t put pkg file in PS3 or UPDATE folder); close archive when done
  8. Open eID_Root archive and extract .pkg file to root of USB Stick; close archive when done
  9. Open Rebug Tookbox archive and extract .pkg file to root of USB Stick; close archive when done
    1. NOTE: downloading pkg’s from other sites might not be archived; either way you get them, you want .pkg on the usb stick
  10. Remove USB stick from computer


Flash Dump & QA-Mode:

  1. Insert USB stick into PS3, using the RIGHT USB SLOT on the front of the PS3
  2. Boot up PS3
  3. Under Games, scroll down to “Install Packages”
  4. Install Rebug Toolbox package
  5. Launch Rebug Toolbox after install
  6. Accept note (if it appears) that not all options are available to you
  7. Go all the way tot he right “UTILITIES”
  8. Toggle QA Flag – Set to ENABLED
  12. Scroll to the left and do a full-restart of system
  13. After restart, shut down system


We’re dumping the eid key in case at some point in the future we should ever want to convert to a DEX system.

  1. Boot up PS3, ensuring USB stick is in right usb slot
  2. Under Games, scroll down to “Install Packages”
  3. Install eID_root……package
  4. Launch eID_root_Key
  5. Screen will go black
  6. System will reboot
  7. At this point, there is a file you need to acquire on your internal hard drive; either FTP or use MultiMan to retrieve the files.
  8. Launch Multiman (assuming you have it on your PS3)
  9. Launch Multiman file browser
  10. Navigate to /PS3ROOT/dev_hdd0/tmp/
  11. Copy the file “eid_root_key”
  12. Paste it to /dev_usb0/ or whatever your USB drive is listed as
  13. Navigate to “PS3ROOT/dev_hdd0/game/
  14. Copy the folder “FLTZ00010″ and paste to your USB stick
    1. Note, this is for 4.50 but is available in 3.55
    2. I copied it out just as a “just in case” instance
  15. Exit Multiman, power down PS3

Change Firmware to 4.55:

  1. Turn on PS3, making sure USB Stick is in front right usb slot
  2. Delete all homebrew packages
  3. Go to SystemUpdate, From Storage Device, and install Rogero 4.55 from USB Stick
  4. System will probably reboot
  5. Install MultiMan

If you have any problems, check out the developer’s site.
