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!

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."

Sometimes when I try to decompress it says "inflated: -3" and then says written 0.

Why does it do this?

Forgive me, but am I understanding this right. That there is a slim chance that you guys cauld maybe be able to backword engineer singed sony firmware, then add some extras of your own, then repack it and hopfully we can then use that FW on our ps3 giving us the chance of installing maybe other os.

Because I really do hope so, as I have a ps3 60gig with the 4 usb's and card reader. now with a 500gig drive and fw3.41. no blue ray tho, and would love to install Yellow dog linux without useing a jailbreak, that I dont have. lol. Thank god its the christmas break and you guys are finding the time to work on this aswell. Thanks.

merry sliffmas all.

I'm working on it, it appears to be crashing, so trying to debug now.

Unfortunately I have to go out now. can't seem to run in release.

int inf(u8 *source, int source_size, u8 *dest, int* dest_size)

ret = inflateInit(&strm);

seems to be the culprit in it crashing, but without zlibs debug symbols and without a bit more time i can't determine why this is. my source is on the previous page, so maybe someone else can take over, should be back tomorrow at some point to continue.

sorry guys
