I RMA my Mini 4.6k and just recieved a new one. It has an old fimware don't know which version but it is one of the old ver 3.x. Anyway I tried to update the firmware and it refuse to recognise the camera or when it does it fails the update right at the begining. Do I have to update the FW incrementally or is this another RMA?
I sussed it. Have to downgrade FW to ver 3.0 and then update to latest FW.
