January 24, 2012 // 3:05 am - I have done this PS3 PUP Unpacker & Decrypter v2.2 homebrew application tool (basically is an script that use other tools) a long time ago for easily unpacking a PlayStation 3 PUP file for those who don't know how. This works on Cygwin and Ubuntu (not CMD windows)

Download: PS3 PUP Unpacker & Decrypter v2.2 Homebrew App

You can choose what to do with this tool, like Unpack PUP, decrypt SELF files, etc... (see README for info):

PUP Unpacker & Decrypter v2.2 By Evilnat

Usage: pup_unpacker.exe [OPTION] filename.pup directory

Example: pup_unpacker.exe -all PS3UPDAT.PUP OFW355


[Register or Login to view code]


1) Unpack folder of RAR on your home directory in Cygwin (C:\cygwin\home\XXXX\Unpacker)
2) Copy PS3UPDAT.PUP file you want in it
3) Open Cygwin's console and enter the folder
4) And type: (OFW_355 is an example, you can change this)

./pup_unpacker.exe [OPTION] PS3UPDAT.PUP OFW_355

[ Example: ./pup_unpacker.exe -all PS3UPDAT.PUP OFW_355 ]

5) Now depending what option you had choosen the executable will do it all automatically

All is done, "dev_decrypted_unpacked" folders contain self decrypted files

This program requires certain exe files and PS3 keys that are included in RAR, DON'T DELETE THEM. If an error occurs it will stop automatically, showing what has happened. Hope this helps someone

Would be really cool if you could repack it into a new PUP file.
