i have a (model) ceche ps3. i only use it as a server for music and movies from my pc. the other day i upgraded my firmware to the latest version after many years of never upgrading the firmware. now i have the 'cinavia' issue on some movies. the 'fixes' i found on line do not work.
in doing some research i noticed that v3.10 was when cinavia was added.
is there any way of going back to v3.01 and if so how would i do it?
