PSGRADE Free PS3 Downgrade Hex Released - Master Key Found!


Sponsored Links
211w 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

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!"

hey! leave the e3 alone, its a fine device. the 4mb on-board storage is the space for payloads, how cool is that.

seeing as we dont have any self files other than the downgrading and turning off service mode one - nothing lol.

sony can do a whole lot though. change serials and ids and reassign hardware etc. but hey, i don't know everything.

My second favourite and the second cheapest clone now supports downgrading!
PS3USBJAILBREAK Downgrader released - Date: 12-08-2010

Downgrader for PS3SUBJailbreak has now released.
Please download our programming tools v1.2.8 to reflash.


Unrelated news: The lowest you can downgrade without failure is 2.30! And you cant downgrade/upgrade to a debug firmware without failure either!

Recover your PS3 by running the 3.41 modified firmware or in the worst case re-enter service mode and try all over again.

Hey boss you should note that I had previously discovered the lowest firmware you can goto is 2.30 - Go any lower and it will fail
