Full PS3 QA Flagging Method Revealed - Button Combo and Token


Sponsored Links
166w 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.

Previously released information regarding QA Mode:


*runs away before the lawsuits come flooding in*

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.

Here are a few more updates via GitBrew Tweets for those following: twitter.com/#!/gitbrew/status/86942755430998016

[*]Bootloader has been dumped from a nand successfully. Nor is going to be dumped next. Rootkey, you're now in our grasp.
[*]CFW we will not release for 3.56+ unless the PS3MFW team finds a way to do that again . an exploit for other deelopers to work
[*]Or the 360 guys since it's also altivec which would help massively. We have the documentation. Would just be easier for them.
[*]Rootkey = per console key. You would need to dump your own key in order to decrypt your bootloader and metldr as far as i know.
[*]It's loaded each time lv0,lv1 and lv2 are loaded. Patching a few things to get it should be somewhat easy
[*]We can create our own lpars and repositories. Anything is possible with linux just gotta find the right workarounds. We currently do not mess with game saves.
[*]Encrypted, we have a few theories on how to get the rootkey since it's called in lv1 and lv2. R/W to lpars =

Unless i misunderstood, this sounds awesome dave! I'm currently on 3.15, but want to have 3.55 functionality while keeping OtherOs.

Thus far, just haven't upgraded to a higher fw until one supports retaining OtherOs like yours does. Would you be inclined to share your fw creation? Don't have the expertise to create my own unfortunately.. a link or PM would be awesome!
Sorry I can't upload my firmware, due to not wishing to break any laws, nor do I wish to work for facebook, sorry I hope you understand. lol

There is endless info and tools, on creating your own firmware, ask in the help and support if you need help, as it would be unfair to thread wreck this thread. if you need a starting place tho, find and download PS3MFWBuilder Portable and ps3mfw 02 both of them, sorry I don't have the links anymore.

I also found to get the best results creating your own firmware was using a clean install of winxp, none updated, with the minimal drivers installed and no .NET, anti virus or firewall installed.
If I downgrade from 3.55 to an earlier fw such as 3.15 could this repair my blu-ray?
No after you downgrade you lose the ability the play BluRay.

Hi!

I want to install Linux on my PS3. I have got a PS3 Slim CECH-2004A 120GB and CFW 3.55-kmeaw installed. I want to use Rebug’s Boot OtherOS++ & OtherOS Prep Tool to install it. And I want to install it on an external HDD.

So I have some questions. Is everything ready to be installed? Have I forgotten about something? Will everything be successful?
Thanks in advance
