Debug output[edit]

The qa flag has some options to enable some debug output.

Does anybody know or has an idea about:

  • In real life how does /sony/ retrieve the debug information? do they use proDG?
    • So does it open the required ports to connect using prodg?


if someone is interested on a GameOS app to QA-flag : http://www.pastie.org/2105541 you can finish this one :D it "should" work.. but I havent tested it.. it is already too late for me :S ~~PsiCoLeo



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.

button combo: L2+R2+L1+R1+L3+dpad_down

index0: 0x00
index1: 0x00
index2: 0x0F (L2 0x01 + R2 0x02 + L1 0x04 + R1 0x08) 
index3: 0x42 (L3 0x02 + dpad_down 0x40) 
  • Advanced token flag is at offset 0x2C (byte 44) within the decrypted token/flag array. Still don't know which bits to set.
  • Special execution mode is at offset 0x33 within the decrypted token/flag array (0x01 : allows firmare downgrade)
  • undocumented1 is at offset 0x27 within the decrypted token/flag array (0x02 : undocumented)

QA-Flag:

  • 0x01 : Minimum
  • 0x02 : Advanced
  • 0x03 : undocumented2


vsh.self checks pad combo

sys_init_osd.self checks QA-seed/token

changes in HV[edit]

sysmgr_ss.fself runs in process 10 instead of 9. its quite different compared to retail proc 9.
you can extract the processes in your hv dump with this python script:
