You open the .flp in a hex editor (like HxD) and find the byte representing the version number.
However, the ethical landscape is nuanced. The "Verified" label mitigates the primary risk of downgrading: malware-laden custom firmwares. By enforcing a cryptographic match to Apple’s original IPSW, FLP ensures that a user cannot be tricked into installing a spyware-infused OS. Yet, the tool still enables a user to deliberately expose themselves to known exploits. This creates a tension between user autonomy and security hygiene. Should a user have the right to run an insecure but functional OS on hardware they own? The FLP Downgrader answers in the affirmative, echoing the ethos of the early personal computing era.
