229w ago - Despite retiring from the iPhone and PS3 scene shortly before PS JailBreak first surfaced (amid rumors from one reseller that appear to point in his direction), today GeoHot has reappeared and shared dePKG which is a PlayStation 3 Firmware Package Decrypter!

Downloads: dePKG PS3 Firmware Package Decrypter / dePKG r1 PS3 Firmware Package Decrypter by daGraveR / dePKG (Pre-Compiled x86_64 and x86) by daGraveR / dePKG (Pre-Compiled Win32) by XVortex / dePKG (Pre-Compiled Win32) and Dissect_CoreOS by cory1492 / Decrypted CORE_OS PKG UnPack Script by anomaly / CORE_OS_PACKAGE.pkg Extract by talruum / Guide: Extracting dev_flash from PS3 Firmware Updates by netkas / FwTool to Encrypt PS3 Firmware Package Files by waninkoko / PS3 Firmware 3.41 Decrypt / PS3 Firmware 3.50 Decrypt / FwTool (Pre-Compiled) by evilsperm / PS3 PUP Update File Extractor/Creator and PS3 PUP Update File Extractor v2 by KaKaRoToKS / PS3 Decrypt Tools (Windows) / PS3 Firmware Toolbox v1.0 and PS3 Firmware Toolbox v1.1 by Chossy / PS3 Decrypt SELF by GFK

In his post, GeoHot simply stated the following, to quote:

"A Little Gift for the Scene
#1419148 - Pastie

Decrypt pkg files computer side.
Mad props to fail0verflow"

Additionally, cory1492 states the following there: "CORE_OS_PACKAGE is NOT a .tar, it's a flash image - to extract it's contents you need to parse it out... a really shoddy/quickly made win32 built extractor for CORE_OS_PACKAGE is attached. Drag and drop your decrypted CORE_OS_PACKAGE onto the exe and it will extract the binaries inside (keep in mind most everything inside it is crypted, it contains the lv1/lv2 selfs and some spu modules and the like.) There shouldn't be anything in there that would prevent a very fast port to *nix (and many thanks go to graf_chokolo for partially documenting the structure on his hv reversing page at lan.st wiki.)

Also did a msys build of the depkg for windows which doesn't rely on external code, source included along with all the COPY notices that go with the aes implementation I used (also I'm running it on win7 x64 from the command line without issue, though it is a 32bit targeted build.)"

As a follow-up, Mathieulh Tweeted the following confirmation: "http://pastie.org/1419148 <== thx geohot /me whistles"

To quote from PSGroove: "The app is very useful for devs, that are planning to look into Sony's official firmware files. dePKG is a linux app, that will decrypt PKG files (not to be confused with PSN PKG files), that are within PS3UPDAT.PUP files.

This will allow devs to take a look at files such as CORE_OS_PACKAGE.pkg, from the convenience of their PC. Previously, the only way to take a look at these files, was via graf_chokolo's method, which utilized the PS3. Geohot's app is ready to be compiled and includes the necessary decryption keys."

The PS3 Firmware Package Decrypter source code is linked above, and also can be found below as follows: http://pastebin.com/qvJdMtvX

i.e the update.pup file needs to be extracted first!


Yeah, my bad, I didn't read previous posts

A few things.

#1 you need to un-PUP the file first (use something like PUP Extractor from the Download section here)

#2 You need to specify a target (like in : ./depkg CORE_OS_PACKAGE315R.pkg CORE_OS_PACKAGE315R_decrypt.pkg

Just a little tip as it's happened several times already in this thread... when you reply (or quote), leave off any "@" characters or use "AT" instead guys, otherwise the post will be sent to the moderation queue and will take minutes/hours to appear because this is one way we catch spammers via their e-mail addys in spam posts.

They can't really remove GameOS, so they are screwed for sure. Thx Geohot

BTW, I used gpup to extract the PS3UPDAT.PUP

Same results here, but... does your code look correct to you?

On mine, it seems to be good up to 0x460, then a large section of 0xFF's, followed by un-decodable data. I tried loading into IDA, but the data starting at 0x40660 isn't PPC code.

It could be that it's 3:00am and I'm doing something wrong
I'll try with a different PUP...
