= | = Playstation Update Package (PUP) - Discussion/Talk = | ||
What is the part that defines, what firmware it really is?. I mean, for firmwares below 3.55 we have all the keys so whe can forge any PUP and make it appear as a +3.55, that would be a way to downgrade, without the need of a dongle and recovery mode. | |||
I know there are version strings in pupheader,version.txt, info0, and in vsh.self.. but what is missing? What isn´t correclty set in mfw to make it pass the checks of a legit +3.55 fw? | |||
We are using recovery mode to downgrade because, we haven´t found a way to create a legit +3.55 | |||
