November 29, 2010 // 7:43 pm - A few weeks back graf_chokolo announced that he decrypted PS3 Firmware 3.50 and work on a free public PS3 Downgrader was underway, followed by a PSGroove Payload update to decrypt PKGs from PlayStation 3 PUP Files with today's update including the OtherOS.self and Lv2diag.self from a PS3 Service JIG decrypted!

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

Sir, that is about the nicest thing I have seen in a long time.

I hope you will get to eat the most delicious christmas ham, you know the one that just melts in yer mouth and that Santa (yes, he do exist do not argue with me ) will bring you the next cutest girl there is since the cutest is for me.

Ok, seriously. That is really nice of you to offer the board for free.

I have an sx28 devolopment board. I brought it a while back to preform the revised xorloser exploit (geohotz) however other things came up and it has been in my drawer since (unopened) I will happily offer to you if you need. Anything to help progress. Just give me the nod and I can post out today no problems.

Great work. These are very exciting times indeed.

Forgot to mention. I don't expect any monies for the board. I will give it for the good off the scene.

So decrypting is done, now he needs to edit and compile the stuff. Hell, give this guy what he want, if you can offer it ! Why he do this on his own, he can get the files from Team Jailbreak and take a look on it, wouldn't it be easier and faster ? Nevermind, this is the most interesting progress I fallow these days. Hope to see a working downgrader to X-Mas.

Yes, I am equally anticipating this decrypter. I can feel it in my bones. This will be accomplished with or without this version posted. Time fellas, time. PS3 is hacked, there is no stopping us!
