GeoHot Releases dePKG - PS3 Firmware Package Decrypter


Sponsored Links
207w ago - Despite retiring from the iPhone and PS3 scene shortly before PS JailBreak first surfaced (amid [Register or Login to view links] 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 [Register or Login to view links] / FwTool to Encrypt PS3 Firmware Package Files by [Register or Login to view links] / [Register or Login to view links] / [Register or Login to view links] / 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 [Register or Login to view links], 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, [Register or Login to view links] 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."

i doubt its that easy to make a hybrid 3.41/3.50 firmware etc.

but as for giving anybody a ylod - HIGHLY unlikely

Could you upload your PUP so a brave soul like sk group can try it. It does seem like your PS3 died at a very coincidental moment, if the hybridized FW works, then we maybe able to mix 3.55 with 3.41 and keep the best of both worlds.

And, we don't know how to bypass the chain of trust yet.

We need to change the loaders, or bypass them. Just setting up 3.55 apploader on 3.41 doesn't work too, 'cause 3.55 requires every loader from 3.55 and so on.

We still need more info to come public

thank you for the explanation.

When the console displays the yellow light, its indicating a hardware problem. If there was a software issue youd have the red screen error or you would have a flashing red light.

I thought you of all people would know this. You simply had bad luck.

Edit: I'd love to try your pup

Repack PUPs using gPUP (found on this forums)

And a word of warning: Do not flash any customized firmware that you create

I tried to do a 3.41/3.50 hybrid, replaces CORE_OS_PACKAGE.pkg of 3.50 with the 3.41 one, repacked it and flashed it through service mode...

Guess what...: YLOD
