The unit is full functional, but as i add Europe 2016.30 NTU UNLOCKED (already tested on another device and i am positive that map is UNlocked), the device gives error :

"Cannot unlock maps"

"Maps are corrupt and cannot be used. Go to..."

I thought i may find firmware and "treat" it with IMGPatcher and then write it back to device.

thanks
