    PSGRADE Free PS3 Downgrade Hex Released - Master Key Found!

    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 / psgrade_teensy_at90usb1286_16.hex by littlebalup

    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 AT90USB162-8mhz
    PSGRADE PS3YES AT90USB162-16mhz

    This is the last line from psgrade_ps3yes.hex
    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!

    This is great news! I actually have a couple teensy 2.0++ on their way right now! So, this is the open source we've been waiting for? Wonder who decided to 'leak' it from the commercial players?
