129w ago - Since the release of
PS3 Firmware v3.55 there is no sense in keeping the master key a secret any more - it has been released, along with unencrypted payloads, and a promise to release the source-code by PS3YES for a free
PSGrade PS3 downgrader.
Download:
PSGrade /
PSGrade PS3 Hex Codes
Of note, the downgrade hex will only work on PS3's with a firmware of 3.50 or below.
The same team which brought the PSN spoof for online support of jailbreaks now has also brought us a Free Downgrade HEX for the PS3! PS3YES has released un-encrypted HEX files for downloading.
They promise open-source code to be release soon, but find below pre-compiled HEX files:
PSGRADE AT90USB646-16Mhz Teensy++ 1.0
PSGRADE AT90USB1286-16Mhz Teensy++ 2.0
PSGRADE AT90USB1287-8Mhz
PSGRADE PS3YES
PSGRADE PS3YES AT90USB162-8mhz
PSGRADE PS3YES AT90USB162-16mhz
This is the last line from psgrade_ps3yes.hex
:10164E00FFFFFFFFFFFFFFFF3278572D9090D5ACC5
:0C165E00AEF903CA1AB65EF1B7694CDEA3
:00000001FF
Of note, The master key has been stated to be:
04 4E 61 1B A6 A6 E3 9A 98 CF 35 81 2C 80 68 C7 FC 5F 7A E8
Furthermore: A PS3YES flash update and PS3 Downgrade guide have been posted
here and PS3Key flashes have been posted
here.
PS3YES has stated, to quote:
"Our downgrade firmware is based on the PSGrade project, we will open the source soon.
Support for the following:
PS3YES AT90USB162 8mhz
PS3YES AT90USB162 16mhz
AT90USBKEY at90usb1287 8mhz
Teensy++ 1.0 at90usb646 16mhz
Teensy++ 2.0 at90usb1286 16mhz
Remember PS3YES were the first to release that PSN Hack that lasted a week on their Chinese forums!
Also sadly v3.55 is out so you can only use this great release to Downgrade v3.50 or LOWER firmwares!
NOTE: Importing the HEX to other devices using current payload converters will NOT work!"
graf_chokolo says: The key from KaKaRoTo for 0xAAAA dongle id is fine Just tested it by communicating directly with USB Dongle Authenticator from GameOS through DM VUART. Congratulations KaKaRoTo Good work!
i noob, tanks...
because it's for Atmel AVR chips only.
I've tried to compile PSGradePIC from Notari's sources (changed jig key to a working one). Looks like it's not ready because i have many errors while compile. After fixing all errors in sources, i've got another error: out of ROM memory..
Why don't you try evilsperm's source?

I will attach all of the hexcodes later tonight to various posts here and then put the main download link for them all in the first post.
