Need Help with Flight controller

Hi I am locked down in Kenya on a Locust control contract. Was bored so I decided to order a somekind of 250 kit localy. got it out of Nairobi just before place was locked down.On recieving parcel, the Flight controller are a generic SP racing F3 not the delux version was told it would be original. Ok I have build the frame was told by sales person to use open flight. Done that but can not seem to get past upgrade page keeps telling me I have to upgrade manualy. downloaded libre flight and beta flight with no luck. and getting any info from there seems hopeless
Thanks Chris
