February 22, 2013 // 8:07 pm - Today PlayStation 3 homebrew developer RazorX has released PS3 CFW EBOOT Resigner v1.01 followed by v1.03 and v1.05 which is an x86 / x64 application for updating 3.55 and 3.41 CFW game files for use on 4.XX CFW.

Download: PS3 CFW EBOOT Resigner Homebrew App v1.01 (x86 / x64) / PS3 CFW EBOOT Resigner Homebrew App v1.03 (x86 / x64) / PS3 CFW EBOOT Resigner Homebrew App v1.03 (x86 / x64) (Mirror) / PS3 CFW EBOOT Resigner Homebrew App v1.05 (x86 / x64)

To quote: Hey guys i got a very simple very noob proof app for you i've put together, very simply all you do is put an EBOOT.BIN into the same folder as the app then launch it and you can select from:

  • CFW 3.40
  • CFW 3.55
  • CFW 3.60
  • CFW 4.20
  • CFW 4.30

and then choose either:

  • NPDRM EBOOT
  • DISC EBOOT

Then the app will do the rest very simple very easy very fast and an all-in-one application however it will require you to install 7-Zip, i was going to include it into the app but then my virus scanner thinks it's a virus and deletes it because it's stupid so just install 7-Zip and your golden.

Enjoy

Update: I've just updated my app to v1.01 now it will retrieve the content id from the eboot and ask you if it's correct if it is enter "y" for yes and it will use it, if you enter "n" it will then ask you to enter a content id in which case you can enter whatever you want then hit enter and it will use that.

Update 2: Added a x86 and a x64 version to the zip file.

Update 3: Added the ability to patch pkg files and Added 7zip built in so you no longer need to install it

Update 4: Updated pkg section, now you can repack games/homebrew, gamedata, ps1 games & minis with the last 3 you will need to enter the contentid also you can now change the package version of any of the pkg options.

Update 5: Added contentid app and param.sfo editor app from aldostools (thank you aldostools) to allow you to find out the contentid from any pkg you gonna use and to allow full customization of the param.sfo file, all build in to this app and setup to automatically load the pkg or param your using.

Update 6: Updated pkg unpacking process so now it shouldnt have a problem unpacking anything the keys are out for. Updated script so now it no longer asks you for the version now it extracts the version directly from the PARAM.SFO.

Hint: If your having problems with the repacking of the pkg please check the contentid against the param.sfo i had problems repacking a pkg until i realized the titleid in the param.sfo did not match the titleid that is part of the contentid.

Here are a few quick updates from naehrwert (twitter.com/naehrwert) for those following:

  • haha just figured the eid3 algo, nice!
  • KaKaRoToKS and I added basic NPDRM support to scetool
  • SELF generation works now for SPU and PPU, except for compressing the data and NPDRM
  • added SPU SELF generation to scetool

Also from his site: nwert.wordpress.com/2011/12/24/individual-infos/

Individual Infos

One of the PS3′s console specific cryptography works as follows:

At factory time there is a console specific key generated, probably from a private constant value and a console specific seed. Maybe that’s the key used for encrypting bootldr and metldr. Fact is, that metldr stores another console specific keyset (key/iv) to LS offset 000000. That keyset is probably calculated from the first one. At factory time the isolated root keyset (how I call it) is used to encrypt the console’s “Individual Infos”, like eEID.

But not the whole eEID is encrypted the same way, special seeds are used to calculate key/iv pairs for the different sections. And not even that is true for every eEID section, because for e.g. EID0 another step is needed to generate the final section key(set). Each of the isolated modules using such an “Individual Info” has a special section that isoldr uses to generate the derived key(set)s.

But the generation works in a way, that the section data is encrypted with aes-cbc using the isolated root keyset, so it is not possible to calculate the isolated root keyset back from the derived key(set)s, because aes shouldn’t allow a known plaintext attack. So far I can decrypt some of EID0′s sections, EID1, EID2 and EID4. EID5 encryption should be similar to EID0′s but I lack the generation keys for that one.

Here is a follow-up from his blog today as well for those following: nwert.wordpress.com/2011/11/29/about-spu-channels-64-72-and-73/

If you are reversing the PS3′s isolated SPU modules, you will eventually notice channels 64, 72 and 73. Here are some C functions, that roughly describe how they work:

About SPU channels 64, 72 and 73

It seems that lv1ldr is storing it’s version into a special storage area.

And e.g. isoldr reads the version from the storage area and compares it to it’s own version. If the check fails, isoldr will just stop execution.

I wonder what else is stored in the area and how long the data in it persists, so my next idea is to code an isolated elf, that allows me to specify the value written to channel 64 and then dumps the data from channel 73.

Yep. WE mortals don't do nothing with this stuff. But i suppose it's an advancement about a free solution...

Oh, some news: And no, I won't release eidtool. If you want the algorithms, you'll have to start reversing

Cool, we can close this chapter too
