JaricraB is back with a great update on his blog that he is working on a way to find the PUP key on the PS3 using his previous ways of dumping the LVL2 Ram thanks to the improved XorLoser Exploit based on the original GeoHot Glitch hack which caused Sony to decide to remove the Other OS from our PS3 systems.
If JaricraB is successful in finding the PUP key, we will be able to package our own updates, with the end result of maybe rolling back the firmware, or returning Other OS to the deleted older systems running the new v3.21 or later firmwares.
But sadly, he is having problems and asking those that might be able to help to contact him directly at firstname.lastname@example.org
You can read all about his ideas of finding the PUP key over at his Spanish blog here: http://jaicrab.blogspot.com
Already there is someone helping him translate everything over to English for him here: http://jaicrab-en.blogspot.com
Attached is his program to help find the PUP key, and you need also another HDD to do swapping back and forth to help decrypt the data.
Thanks to ModRobert from http://eurasia.nu for informing me about this wonderful update in the PS3 world, that might someday open the door a bit more in the PS3 scene.
