PS3 Full QA Flag Token & Button Combo Revealed

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.

*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.
