157w ago - A few weeks back graf_chokoloannounced 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

How would they patch this exactly? From what I understand the Jailbreak dongle emulates the JIG device used to boot the system into Factory mode.
I dont believe they would go down the route of changing JIG hardware, I think they would change the response challenge in the firmware itself, then update their JIG dongles.
Sony wouldn't lock themselves out of their own consoles (obviously)... unless this is a similar incident to when they removed OtherOS support.
LOADS of people whined, Sony metaphorically slapped everyone with the excuse "We did it to protect everyone's best interests..." more like "We did it to cash in on future hardware & to ditch the freeloaders from our system (Linux Users!)..."
Who exactly is the 'Everyone'? A small group of autistic aliens that sony keep locked up for game testing & feed them on crack & sushi?
