Question for those with a Test kit
Question for those with a Test kit –
i was wondering, since we cant decrypt eboots that are 3.60 is it possible to unencrypt them with a test kit running 3.60 debug fw?
i ask because i remember seeing some time ago a method of decrypting SELFS and SPRX's if its not possible forgive me, just a thought.
I think they answered that question in the thread regarding the 3.60>/= Debug fws. No
Don't Feed The Trolls Past Midnight
i remember it was mentioned that the decryption was done on the actual system, however i dont know if it required a "payload" or not
if a debug console can play retail games it most certainly can decrypt retail selfs/sprx. i think the problem is we cannot see the ram, so we cannot store the decrypted selfs/sprx. graf did this on 3.41 by the use of a payload, and he didn't need keys, he used the ps3's hardware to decrypt the files. im not sure how he did it but, like i said he used a jailbreak payload and im not sure it can be adapted to work as a debug fself or not. i suppose its worth looking into. but the chances of a developer having a debug console to test it out on is slim to none.
well, we have a few people here that have test kits, if the method could be adapted, we could then have decrypted 3.60 eboots, and then have the signed to work with 3.41 or 3.55 thus the newer games would then work on older firmwares
I have a test kit, but keep in mind that 3.60 consoles are not vulnerable to payloads.
could anyone verify that a payload is absolutely needed, or was a payload needed since a retail must be jailbroken to run unsigned code?
im sure it could be, but im also pretty sure it would need hypervisor access (need to exploit into it) to be able to work (i remember graf saying lv2 and lv1 have TONS of holes so maybe this isnt that difficult). but im not sure, maybe it could be done without, this is probably the easiest way for us to decrypt newer eboot's and it a pretty good idea though. should be investigated further.

The "flaw" that you can tell the PS3 to decrypt stuff while having PPE access (which GameOS does) still remains !
are you sure ? i'm pretty sure SELF/SPRX decrypter relies on at least Hermes/PSJailbreak payload to do its job...
