I found a 4.25 EBOOT thanks to sharboy Now I test it.
Do you have maybe a 4.21 appldr?

[DEFAULTDNB]

No I dont..., but good luck

DEFAULTDNB...

Your right in some parts yet wrong in others...

1) Yes with the leak of lv0 keys we can decrypt lv0 > extract appldr > decrypt appldr with metldr keys > locate the keysets >> unicorns

This then enables us to decrypt any eboot / sprx etc for games and resign them with 3.55 keys ..

(That is what is what you're looking to do)

2) fail0verfl0w exposed a flaw in sonys encryption ECSDA or whatever its called lol...

- what does this mean? it means we can calculate the private keys
- what are private keys ? there used to encrypt sony files.. aka SELF. SPRX etc, etc

So up until 3.55 we can calculate every key sony used to SIGN there files, thus making valid application, thus enabling homebrew etcc or whatever

3.56+ that has been fixed and we can no longer calculate the private key... but yes we can still grab the public keys, as they are within the FW..

Public Keys Decryption
Private Keys Encryption

3) geohot released hes NPDRM tools which had static private keys, sony apparently blocked them keys, once npdrm was worked out, new tools had been released to select different keys, aka dont use geohots tools, there flop, even math stated this..

4) you can use any sony npdrm private key in scetool and produce homebrew with will execute on any OFW... aka 3.60++ .... sony can't block there own keys, cause then all there old psn games etc would not work unless updated and there not gonna back date the updates for extremely old games lol..

5) i cant remember what else you asked..... but yes we can decrypt all current games and resign them for 3.55 if needed..

6) lv0 private key cant be changed as bootldr cant be updated, so for example, every new fw out can now become CFW... or for instance step 1)... aka you download 4.30 extract the pup or install and nor dump..... decrypt lv0 etc etc (step 1) and add the new appldr keys to scetool...

thier chain of trust was "fixed" in 3.60 but once you pwn bootldr its game over, as bootldr would hold lv0 keys and lv0 signing cant be updated.. so pwnddd for lifeeee !!!

put it this way if you know how to add peek / poke and whatever else, or even know how to use scetool and ida plus a hex editior you could ultimate always gain public keys to decrypt games.... or make new CFW lol

@ danixleet: thanks for explaining all that! so the leaked lv0 keys will not only lead to decrypting anything up to 4.25, but they are leading to the encryption keys (private keys) as well? I thought that hole was fixed by sony and no one in the world will ever see the private keys again?

He's saying that you can sign homebrew with old NPDRM keys which haven't been revoked. We don't have 3.60+ private keys for RETAIL signing (not NPDRM), but we don't need them as NPDRM keys can be used instead and the homebrew signed as NPDRM content.

thanks for explaining.

btw: where is the "new eboot wave" that was supposed to come with those keys? with lv0 it should be possible, right?

I don't think so?

Since each time a new firmware comes out from now on it will be relatively easy to make a CFW from. "decrypted eboots" or eboots signed with lower keys are likely to become a dirty legacy item that smelly people use

I'm sure there will be a load of 3.55 eboots coming along shortly of course, but it's a bit pointless, you might as well just use original eboots with each new CFW that will be released.

That will be the "proper" way forward. People who ask for 3.55 eboots will become the same as those annoying people who overburn XGD3 games on the Xbox 360 and complain when they get booted back to the dashboard with "unsupported data" messages.

Keep with the times

Just to make sure I understand this correctly, my current game directories that contain modified eboots (allowing the game to be played on 3.55), I just need to follow the steps you outlined above (after getting my system to Rogero CFW 4.21 of course.)?

Hey Danixleet - I like to learn. can you perhaps teach me how to did this as I want to use Blackbox FTP as well. I tried and got the new EBOOT.BIN but how to make it a pkg file so I can install on PS3?
Cheers in advance
