BD-F5900 Firmware Downgrade to Avoid Cinavia

[zhal696]

I see the proof of concept sticky post on this forum. Mainly there are D series blu ray players listed with some E series success stores. However, I don't see any confirmation regarding F series success stories.

I'm looking to downgrade or straight up change the firmware on my F5900 to avoid the Cinavia messages when running movies off my plex server. Anyone done it? If so link the detailed guide, pretty please. Any recommendations would be appreciated.
