QA Flagging

QA Flag

A QA flag is a value set in syscon EEPROM at address 0x48C0A. When this flag is set

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 HMAC 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 SYSCON 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
