PSGRADE Free PS3 Downgrade Hex Released - Master Key Found!


Sponsored Links
194w 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


Of note, The master key has been stated to be:




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!"

So any firmware below 2.30 will say the following in the log: Updating or Verifying failure 0x8002f14b

When the console is booted the green light will flash and stay on for eternity which is the PS3's way of saying that there is a failure.
So I'm assuming us non-PS3Yes users don't have to deal with the Lv2diag.self File 1 and 2 mentioned in the instructions? I've got a Teensy++2 and have the appropriate hex file for it.
The downgrader payload only puts the ps3 into service mode.

The other files do the actual downgrading.

That's the only part that's confusing me...

I didn't mean that really Even though I make my own dongles I'd prefer to have something with PROPER support (chinese albeit) and up to date.

My dongles rely on PSgroove code - they work fine for everything other than DGing.

Lets hope my E3 don't get lost on it's way from the sunny u.s of a. Comes to something when it's cheaper to buy from abroad than your own country because people here (UK) are just greedy. 98% of them are dropshipping for chinese companies just to make easy £££ & charge you DOUBLE of what the item costs just cos they're UK based supplier...

I don't mind waiting for my goodies. Keeps me excited til it turns up

Umm.. see here:
I was running 2.30 and decided to see what would happen if I updated to 3.41 debug using the e3 downgrader. Turns out it bricks it

Heres the log:

Strange part:

os version = 03.4100
build_version = 45038,20100721
region of core os package = 0xa0000000
build_target = DEX-ww
build target id = 0x82
manufacturing updating SUCCESS(0x8002f000)

ALSO:

Turns out 2.15 debug doesnt even launch, it just makes the green light flash (meaning the whole process will come up as FAILURE in the log)
