PSGRADE Free PS3 Downgrade Hex Released - Master Key Found!


Sponsored Links
217w 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.

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

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'm sure this can be fixed via xregistry seeing as people are saying restoring their flash2/3 does the trick.. also: lol at bul-ray

Edit: what region is your ps3? did you use the modified 3.41?

you should be able to fix it by restoring a dev_flash3 which you prob don't have...

you can try downgrading to 3.15 and upgrading with the legit 3.41 etc

apparently this only happens with NTSC ps3's.

Wow, am I glad I didn't jump on this one! Would this issue have anything to do with the 3D playback upgrade 3.5 applies? But would have thought going back up to 3.5 would resolve the issue!

I have sort of answered my own question.

If I create a new profile the problem disapears. When i downgraded back to 3.41 all the profiles on my system were present but were renamed to *User 1, *User 2 etc. I renamed the profile I normally used, with all my game saves listed, it may be this that confused poor old jap fatty. It still would be nice to have a more elegent soloution but at least the downgrade path works and I am grateful to the those clever devs.
