A hacker known as tihmstar has allegedly demonstrated a downgrade of iOS 9.3.5 to iOS 9.3.2. It has not been possible to downgrade iOS firmware for quite some time. A working method would potentially allow all users to get to a jailbreakable firmware version.
In a video posted to YouTube, tihmstar demos 'prometheus', an upcoming tool which supports downgrading 64bit devices if APTicket (shsh files) are saved and certain other conditions are met.
The video's description says, "It is currently unknown what conditions have to be met to be eligible for downgrade without jailbreak."
On Twitter tihmstar notes, "A different method does exist, but is in development at the moment, so stay tuned and let me figure out how you can use your saved blobs."
At this point, it's unclear if the downgrade tool is legitimate but you can follow iClarified on Twitter, Facebook, or RSS for updates.
