= 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.

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.
**[http://gitbrew.org/~glevand/ps3/pkgs/qa_flag_extra.pkg qa_flag_extra.pkg] // (mirror:[http://www.multiupload.com/KAGDSQ9QG9 qa_flag_extra.pkg (69.98 KB)]) (to enable QA with downgrade)
*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.
==User Submitted Videos==

== 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.
