Stolen m2

Hello there, 3 days before my wifes meizu m2 got stolen. Unfortunately i didnt made a flyme account on it so i can track it. Is there a way so that i can track it with the imei or anything else from its box? Can i make new flyme account from my computer and (with the imei) synchronize the mobile?i am 100% sure that the robber dont know how to put a flyme account so the phone is unlocked. Ty for any answer and sorry for my English
