Editing QA Flagging

[[Category:Software]]
= QA Flag =
A QA flag is a value set in [[SC EEPROM]] at address 0x48C0A. When this flag is set, the token is read from SYSCON and decrypted, this gets passed to various modules to unlock certain functionality.

= QA Token =
A QA token is an 80 byte value that determines amount of functionality on your console.
It is signed with a 20 byte SHA1 key then encrypted using AES256CBC. Please see the [[keys]] page.

== Encrypted Token ==
The entire token is then encrypted with AES256CBC. You will find the keys on the [[keys]] page.
This is then stored on [[SC EEPROM]] at 0x48D3E

== Token Flags ==
The flags are a 40 byte value containing a set of flags that enable specific features on the PS3 console. These flags are largely unknown.

= Setting QA Flag & Token with Linux =

== Prerequisites ==
*First you need to have linux installed on your PS3, you can have grafs kernel or glevands rework

If you are using glevand´s kernel you will have to first enable the require module 

 modprobe ps3dmproxy

*Then you will have to have the latest ps3dm-utils you can get from [http://git.gitbrew.org/ps3/ gitbrew] or here you have a precompiled  [http://www.multiupload.com/CVN3Y9QBQX ps3dm_um] [http://www.multiupload.com/FQNWIBBIOB ps3dm_aim]

and you will need Slynk tools

 Here's my app. I'd have a full tutorial but I'm having to deal with some bullshit right now. Sorry guys.
 I'll make a better tutorial later but basically. Flag yourself. Dump your idps (that's the first 16 bytes of your eid0).
 Type it into my app in the format I provided, click the button, and run that command. Should work.

 [http://psx-scene.com/forums/f149/qa-flags-discussion-86504/index92.html#post842118 Slynk]

== Procedure ==

=== Getting the info ===
First you need your IDPS. Obtain this using ps3dm_aim.

<pre>
# ./ps3dm_aim /dev/ps3dmproxy get_dev_id
</pre>

Write it down and load it using Slynk's Tokenator app.

It will give you the command you should use in linux + your encrypted token. The tool should output something like this:
<pre>
./ps3dm_um /dev/ps3dmproxy set_token 0x7E 0xDA 0xE2 0x68...
</pre>

=== Setting the flag ===

<pre>
./ps3dm_um /dev/ps3dmproxy write_eprom 0x48C0A 0x00
</pre>
(you may skip this step, because UM set_token takes care of it)

=== Setting the token ===
Just copy paste the command you got from tokenator
<pre>
./ps3dm_um /dev/ps3dmproxy set_token 0x7E 0xDA 0xE2 0x68...
</pre>
'''Congrats now you ps3 is QA flagged'''
'''Reboot'''

=== Getting the QA flag menu ===
<div style="float:right">[[File:PS3-sixaxis-dualshock-controller-buttons.gif|200px|thumb|left|PS3 Sixaxis + dualshock - controller - buttons]]</div>

Set your cursor '''on''' (not ''in'') Network Settings and press the key combo (all at the same time):
<pre>L1 + L2 + L3 (press left stick) + R1 + R2 + dpad_down</pre>

You should see Edy Viewer, Debug Settings, and Install Package Files if done correctly.

==Install Package Files==
Will install all package files found on the root of the USB stick sequentially in alphabetical order until an installation of a package is aborted or fails for any reason.  It will work only with properly signed packages.  Unlike the Install Package File function in the Game menu the .pkg extension name is not case sensitive.

Option present in FW 1.02 and above.

As on DEX/DECH Stations is already a "Install Package Files" function, no new icon is added, but the ability to install retail packages via the "game column" "Install Package Files".

=On 3.6x Firmwares=
As we know Sony has <strike>taken QA Flag away</strike> changed the Auth for QA-flag on 3.6x Firmwares. Until someone changes it to work with the new method (which doesnt work on the old), your QA Flag will not work on 3.6x.

From 3.60 Sony added a new step in the authentication process in the [[Iso module]]  "spu_token_processor.self".
This new step is a digital signature verification using ECDSA ("Elliptic Curve Digital Signature Algorithm").
The old token, the IDPS taked from the machine, the version of the Token (1), the array of flags, and the HMAC hash of the previous parts, remains valid as such.
No key (AES, HMAC) were changed in the new module.
However, after the decryption of the token, [[IDPS]] and verification of the machine with which it has the token performs a digital signature verification of all encrypted token (0x50 bytes).
This performs a SHA-1 hash of the entire token (like Sony performed at the time of the digital signature) and passes to check the signature, if it validates the token is considered authentic and returned both encrypted as decrypted (this with the hash hmac set to 0), as happened in 3.56 and lower.
In the event that the digital signature fails, consider that the token is not valid, as would happen if the token decryption fails, or any of your previous checks (HMAC computed with token bearing the token, the [[IDPS]] , ...).
In this case it will return an empty buffer (instead of the decrypted token) and one with a token prepared but without any active flag, or indeed with any digital signature, as happened in 3.56 and lower.
In short it is not possible to put a machine QA in firmware 3.60 and higher unless you are patching the module (thus only work in that customized firmware), or getting a whole token and a valid digital signature for.
Given that the token varies by the [[IDPS]] to prevent universal token exists, only the IDPS should know that token, and change the [[IDPS]] of section one of [[Flash#EID0_-_Section_0|EID0]] (which is what the [[Iso module]] checks), but this could have unintended consequences in some cases.

= QA Downgrading =
Crossreference: [http://portal.gitbrew.org/wikibrew/PS3:Downgrade gitbrew.org PS3:Downgrade] <br />

== Notes ==
These tools COULD format your ps3. (which means Any and ALL psn / downloaded data could be erased)

note: several people noted that they did not suffer from dataloss even after several downgrades, but its good measure to backup before downgrading {esp. ACT.DAT which DO get erased)

== Tools Needed ==
*[http://git.gitbrew.org/~glevand/public/CFW355-OTHEROS++-SPECIAL.PUP CFW355-OTHEROS++-SPECIAL.PUP] // (mirror:[http://www.multiupload.com/UITB9EY84F CFW355-OTHEROS++-SPECIAL.PUP (170.64 MB)] / http://www.mirrorcreator.com/files/TTL1FPNF/CFW355-OTHEROS__-SPECIAL.PUP_links) - QA Flag CFW with SS patches, Can be used to downgrade your ps3 from 3.55 to lower firmwares.

*Firmware you want to downgrade to. (3.41, 3.15)

== Installation Process ==
 1. Install CFW355-OTHEROS++-SPECIAL.pup (Doesn't matter what version you are. 3.55 and lower ONLY.)
 2. Install qa_flag_extra.pkg 
 3. Run qa_flag (It will show up as this, that is fine)
 4. If you hear the beeps, continue. If you do not hear beeping, come to irc.
 5. Reboot
 6. Go into recovery menu and Update your ps3 with the firmware that you want (3.15, 3.41 etc)
 7. have it install
And now you're done. You just successfully downgraded your ps3.

== Known Issues with QA flag / QA downgrades ==

=== Act.dat (PSN activation) gets deleted ===
Make sure you backup the file before enabling QA-extra flag and downgrade. There have been reports of ACT.DAT ("home/000000XX/exdata/act.dat") get's deleted. So make sure to backup that entire folder before flagging/downgrading.
