Decrypted Lv2diag.self from PS3 Service JIG (Teaser)
To quote via
xorloser's blog, linked above, on the PS3 appldr interface reversal progress:
graf_chokolo says: Guys, i know you are waiting for the USB Dongle Master Key from me

I have got now 2 fat PS3 with HV 3.15 but unfortunately no SX28 development board yet to exploit it
But i was not idle and the last and this week i was working on reversing of self decryption. And now i'm able to decrypt SELFs and SPRXs on my exploited GameOS by using HV calls only and no GameOS functions at all

I reversed the interface to appldr which decrypts SELFs on GameOS 3.41.
So you won't get bored until i get the USB Dongle Master Key, i will make my findings and my source code public very soon and you will be able to decrypt your favourite games and programs by yourself :-) Let the fun begin, guys
Here is a "small" teaser of decrypted Lv2diag.self from service JIG

You cannot decrypt isolated SPUs with appldr, i think, because they are decrypted by isoldr.
I'm able to decrypt hdd_copy.self from 3.42 but not from 3.50
otheros.self decrypted
So we can soon work on a PC port of the PS3's FS?
and Ptuchik above... how about Contller Firmwar at 387... devs make mistakes or just name things their way, big typos though, which would make anyone skeptic... nahhh.
Can anyone explain me?
Only then will the fun start... just imagine... upgrade & downgrade to ANY firmware you want & have plenty of fun with homebrew. You could just walk into a shop without worrying what firmware your PS3 will have
