Theres 3 news in one as they all are related...


PS3YES! has just released their own downgrader...

Thanks to: PSGroove.com (http://psgroove.com/content.php?501-PS3Yes-Release-Free-PSGRADE-Downgrade-Hex-Works-on-All-AT90usb162-Boards)

And many thanks to the scene developers that work hard to bring these tools to everyone:

Graf Chokolo, zAxis, Hansi, Hermes, Kakaroto

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

Since firmware 3.55 (http://reviews.dcemu.co.uk/sony-releases-3-55-firmware-update-blocks-downgrade-349069.html) is out for the PS3, you can only use downgraders to downgrade firmwares 3.50 or LOWER!

NOTE: Importing the HEX to other devices using current payload converters will NOT work!

Last but not least, with the release of downgraders, KaKaRoTo has found out the TRUE USB > AAAA Device Key that is used by all downgrading service Jig dongles. There were many so-called "master keys" however, PS3YES! obfuscated the key, xor-ed it with 0x36 and swapped bytes 11 and 16. The real key is below.

0xAAAA dongle key:

04 4E 61 1B A6 A6 E3 9A 98 CF 35 81 2C 80 68 C7 FC 5F 7A E8

What does this mean for end-users? Nothing much except for the fact that now, the downgrader will be open source in the form of PSGrade (https://github.com/zAxis/PSGrade) by zAxis. PSGrade was a work in process (WIP) downgrader however, it was not working as he could not find the key that was needed...until now.

For your convenience, we have included PS3YES! (Fit to all at90usb162 8Mhz and 16Mhz boards), PS3Key, PS3USBJailbreak, P3Go and PSGrade open source files for the usual USB boards such as Teensy, Olimex, Blackcats, Minimus, etc.

I did the downgrading process using a PS3break v1.1 dongle to revert to PS3 firmware version 2.40 and it worked out just fine. Only problem I had was display issues and nothing showing up properly as I use a VGA box + computer monitor rather than a TV. Used my PS1 screen instead (casing unscrewed, to be able to connect it to the console.) so I could check firmware version and factory mode status.
