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 a 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.
Unencrypted Token Structure

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.
QA_FLAG_ALLOW_NON_QA = byte 0x33, bit 0 QA_FLAG_FORCE_UPDATE = byte 0x33, bit 1 QA_FLAG_EXAM_API_ENABLE = byte 0x27, bit 0 QA_FLAG_QA_MODE_ENABLE = byte 0x27, bit 2
