HERE GNSS no gps lock for device

hi all i’ve got a HERE GNSS gps for my cube black 2.1
it was runing all ok but my copter got fliped over on a windy day with no big harm to the copter
just the gps case cracks i re connect the wires and i’ve got the compass working and the safty switch but no gps satelites show up and keep saying “No gps lock for vehicle”
the postive lead for small battery on the gps bord had moved i re connect it but i think the firmware has gone ? can i downlowd it and how
