Full PS3 QA Flagging Method Revealed - Button Combo and Token


Sponsored Links
188w ago - Following up on the previous article, today the full PS3 QA Flagging Method has been revealed including the button combo and token alongisde a PS3 QA Tutorial from Slynk.

To quote: A few weeks ago, several steps were revealed in the process of unlocking a special Quality Assurance (QA) mode on your PS3 console. The mode unlocks a special mode, which is typically only meant for official Sony testers.

Unfortunately, the steps revealed were only part of the process. Developers were scrambling to figure out the button combo that unlocked the special QA mode. In addition, developers still needed to figure out what to change in the QA dummy token. These two mysteries prevented developers from unlocking the mode.

Today however, the Quality Assurance mystery comes to an end. An anonymous and reputable source exclusively revealed to us the two remaining steps. The secret button combination that unlocks the hidden QA mode was revealed to us as being L1+L2+L3+R1+R2+dpad down. Furthermore, the anonymous source told us that users need to change byte 48 of the token seed to 0x02.

Combining this new information with the previously released QA information, developers have everything they need to unlock the mode. Please note, this is not to be attempted by beginners. However, with all of the information revealed here, developers will be able to create an application or custom firmware that automates the QA process.

Information courtesy of anonymous source: Change byte 48 of the token seed to 0x02, hash it, encrypt it, write it to eeprom and flag yourself. Button combo is L1+L2+L3+R1+R2+dpad down. Only works on retail firmware.

By byte 48, I mean the 48th byte. Note that in programming the array of the token seed begins with index 0. So the 48th byte would be seed[47];

This info is more than enough to get someone to make an app.

HMAC to make the 20 byte digest at the end of the token and erk/iv to decrypt/encrypt it with aes256cbc.

2 more steps to go. Need the button combo and what to change in the dummy token.

Brief Guide on How to QA Flag your PS3:

  • Be on 3.55 OFW (not Kmeaw or Rebug CFW)
  • Move the PS3 cursor/select “Network Setting”
  • Punch the following button combo with your PS3 controller: L2 + L1 + R1 + R2 + L3 + D-pad Down
  • That's it, the “Edy Viewer”, “Debug Settings”, “Install Package” Menu will now appear.

Notes: Install Package is useless and can’t install homebrew at the moment – only signed PKGs (and the first one in root of USB only).

Finally, to quote from [Register or Login to view links]: So since this QA thing is worthless anyway - here is the button combo - you need to have the cursor on 'Network Settings' - (it needs to be 3.55 OFW BTW - Rebug won't work - I've already established that) - and do the following button combo - L2 + L1 + R1 + R2 + L3 + D-pad Down.

There's your button combo. 'Edy Viewer' will pop up - Debug Settings will pop up - Install Package will pop up (but it's kinda useless anyway since only retail packages will install, and only the first PKG on the root of the USB stick - yes - seriously). Now you only need to figure out the rest. Yes, this one works - don't worry about it - just go figure out the rest.

BTW - in case some people immediately start trying this out and telling me 'Hey Square - this doesn't bleepin* work' - remember - there are still some pieces of the puzzle missing - the 'community' needs to figure these out. But the button combo is in the bag - don't worry about it anymore, don't go fruitlessly reversing anymore looking for a possible sign of life of this 'button combo' - you've got it. Now figure out the rest.

Wow! No problem by the way if you do move the posts, but that's awesome. I'm just trying to get my PS3-Ubuntu fix. Lets hope this package sees the light of day then. Cheers

I'd also like to note, I think that key I was talking about earlier is for the v3.6x models. I don't know anything about deving or code, but I know when I get a good feeling in my gut. Maybe some devs/modders out there could take a look at it.

I moved these posts to the QA Flag Thread, also... last night on IRC _bubba mentioned the related files/guide may be released soon (Qa.Flag.Token.ComBo.READNFO.PS3-PS3MaTHiEulH) and posted the picture that can be found below.

Also, kinda spaced it, but they were having a conversation on the topic of enabling QA mode. Maybe that helps with the context a bit. Mathieulh was involved in this conversation, he's the one who posted the last little bit past the edits in the final quote.

I bring you (what I think) are the keys. I found these from a user named Slynk: psx-scene.com/forums/826118-post518.html

hmac to make the 20 byte digest at the end of the token and erk/iv to decrypt/encrypt it with aes256cbc.

2 more steps to go. Need the button combo and what to change in the dummy token.

Also in the spirit of sharing, the dummy token decrypts to:

00 00 00 01
idps
... (all 00)
20 bytes of digest

It's 80 bytes long.

More about the key from that user Slynk, apparently this is the new dummy code, anyone care to verify?
EDIT: There's no ecdsa so there's no public private. The other key is the hmac. Man must I be tired >.<

Already decrypted it. And I know the token has 20 bytes of hmac-sha1 at the end before encryption. ^^

But I still need: "What to change to make an "advanced" token" and "The button combo to test it out". ^^

EDIT: btw it's aes256cbc, sames as self crypto for the curious. Yes, it's the hmac key.

The encryption is straight forward, very easy to figure out, and obviously not the hard part.

As to the dummy token, it's nothing more than the first few bytes of the EID0 followed by 00s (which I call flags array) and a hmac-sha1 of the actual token.

The hard part is knowing what values to change, and what to.
