Hi everybody, i have a lumia 920 from TIM carrier, Italy. Now i am in Romania and i have Amber update on my phone but with a software from France and with another product code than my phone. Everything works great only gps has a problem. HERE Maps, HERE Drive+, gMaps, GPSinfo none of these can't find my location. after 10 min of looking for satellites in airplane mode and nothing. I don't know why.I have Romania map downloaded ,HERE Maps set to offline and nothing, outside under clean sky. Could be from the software? Can i flash my phone with one from TIM carrier back,which was released before amber, to downgrade? Thank you.
