December 13, 2012 // 8:44 pm - After being inactive for a while since my previous release because I had a problem, finally I finished to create and fix my personal tools for PS3 PKG / SPKG for CFW 3.55 / 4.XX complete with source code.

Download: PS3 PKG / SPKG Tools for CFW 3.55 / 4.XX with Source Code


This tools are based on failoverflow's tools, but with support for spkg files on CFW 4.XX, for for example, install a PUP directly from XMB or avoid to do a downgrade to 3.55 to install it.

A spkg file contains header/metadata for that pkg who has his name, PS3 on +3.56 checks his header/metadata for matching, if not fails and can't install. On FW 3.55 and below is not necessary that spkg files.

Minimum Requirements

  • Patched spu_pkg_rvk_verifier (disable ecdsa check)
  • Have spkg files on your ".ps3" folder


  • spkg.exe - This tool creates a spkg file from a pkg file
  • unspkg.exe - This tool decrypts spkg files (*.spkg_hdr.1)
  • new_pkg.exe - The tool creates a pkg file and simultaneously a spkg file, the last one is compatible with the first one
  • new_unpkg.exe - This tool decrypts a pkg file and exports his decrypted header/metadata

it would be great if there's a homebrew application on PS3 that can edit the spoof firmware version without installing anything.

Nice! Love these little tools, for people like me learning programming it helps to understand certain aspects of how the memory works in these newer consoles. Keep up the good work! (not sure if this double posted sorry if it did).

Thanks both

With tool spoofer_pup.exe is HIGHLY recommended use PUP file of your CFW you have installed on your PS3, it don't spoof PUP file, it extracts the files [vsh.self and version.txt], spoof them and save in Spoofed folder, then copy to your dev_flash with Dev_blind.

Don't confuse with that friends, it spoof files not the entire PUP

I have done this PS3 PUP / Dev_Flash File Spoofer v3 Tool (basically is an script that use other tools) long time ago for easily spoof necessary files from a PUP file or your own files of dev_flash. This works on Cygwin and Ubuntu (not CMD windows)

Download: PS3 PUP / Dev_Flash File Spoofer v3 Tool

There are 4 tools that makes a different job:

  • keys.exe - Install PS3 keys
  • extractor.exe - Extract vsh.self, index.dat and version.txt of PUP file
  • spoofer.exe - Spoof your flash files [vsh.self and version.txt] (put there in same folder with spoofer.exe)
  • spoofer_pup.exe - Extract and spoof automatically files of PUP (it must be in same folder with spoofer_pup.exe)

You must choose what version and image version you want to spoof in tools spoofer.exe and spoofer_pup.exe, for example, if i want to spoof to 6.40 i put this on Cygwin console (you can choose any image version):

When it finish you have your spoofed files in Spoofed folder. Version must have same numbers of characters, otherwise it give you error on PS3. If you do something wrong PS3 will boot up Red Screen, if that occurs re-install CFW from Recovery Menu.

File index.dat is really not necessary to extract, it creates a new one with spoofed version.txt (spoofed tools does it auto).

I hope this helps anyone. If you see any error or bug please contact me.
