PS3 CFW 3.55 Update (to 4.55)

I have an old, fat PS3 running CFW 3.55 KMEAW and I think it’s time to give it an update. Thankfully, doing so is a lot easier now than it was two years ago.

I haven’t done much in the way of messing with my PS3. I played enough on it with Custom Firmware to finish all the games that I had and really finish up 100% of Final Fantasy, which was the only thing I was really involved in. The problem was that games were coming out and it was getting incredibly harder to spoof higher firmwares on the PS3 CFW that I had in place. In the end, I bought another PS3 so I could have one that would be able to play the newest games; that, and that I wanted another blu-ray player in another room.

Some time ago I saw that there were some updates to get past the limitations of 3.55 allowing one’s PS3 to go up to higher firmware versions. The problem was that the update process was pretty convoluted and needed either extra wiring or usb sticks from reverse-engineering companies to make them work, and even then, there was no guarantee it would work. Eventually, I got fed up with it and decided it wasn’t worth it and gave up.

Most recently, I’ve read that author Rogero has teamed up with some others and decided to bring the firmware up to the most current version (at this time is 4.55). He’s also provided help in downgrading a PS3 in order to get it back up to the current version. So now, I’ve decided to go ahead and update my CFW with a more current version; not to mention that 3.55 gives us the ability to pull some needed files for ‘future’ edits.


 

Before We Begin:

This article assumes that the PS3 is running KMEAW 3.55 which requires no downgrading.

Tools We’ll Need:

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

Definitions:

  • 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)

Most files that are archived are in .rar format (or might be .zip). You will need WinRAR to unpack these. I’m not going into full 100% step-by-step details because if you don’t know how to do this, you shouldn’t be doing it anyway. If you need more finite instructions, please view the original article of CFW 3.55 for examples.

 


 

USB Prep-Work:

  1. Download Rogero 4.55, MultiMan, and memdump 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 memdump archive and extract all .pkg files to root of USB Stick; close archive when done
  9. Open eID_Root archive and extract .pkg file to root of USB Stick; close archive when done
  10. 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
  11. 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 memdump pkg, run app after install, clean FLASH, and exit when finished
  5. Install Rebug Toolbox package
  6. Launch Rebug Toolbox after install
  7. Accept note (if it appears) that not all options are available to you
  8. Go all the way tot he right “UTILITIES”
  9. Toggle QA Flag – Set to ENABLED
  10. EXPORT HYPERVISOR LV1 MEMORY
  11. EXPORT GAMEOS LV2 MEMORY
  12. EXPORT FLASH TO FILE
  13. Scroll to the left and do a full-restart of system
  14. After restart, shut down system

eID_Dump:

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
