PSGRADE Free PS3 Downgrade Hex Released - Master Key Found!

1300°
197w 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:

200w ago - A few days back we reported on the PS JailBreak Downgrade file leak, and today Hansi of PSXCare.com (linked above) has followed up on some previous work and shared a video of a PS3 downgrading with PS Downgrade and a Beagle 480 USB protocol analyzer.

Use Beagle Data Center Software to read the dumps.

One file is a PS3Key boot, the other is a PSDowngrade boot.

The PSDowngrade is supposed to be encrypted and not "analyzeable" according to a distributor. But maybe something can be learned anyway.

Have fun!
