You didn't say how you unlocked the map. Assuming you've used the latest version of gimgunlock-0.03+MapSigPatch, please read the information in that particular thread, specially in post #1 and post #256: [Only registered and activated users can see links. ]
It unlocks NT (not NTU) IMGs in 2014 devices, but not working with all new devices 2xx9 and probably in most of newer devices firmware.
