I have some Problems with my Mi-2. It worked fine till a week ago. Now it says “No Service”. I have no reception. In some areas, near the sending towers, there is a weak reception(Only one bar). It’s not possible to phone. I didn’t change anything on the mi2! I tried my Sim in another cell phone, a nokia c5 and Xperia T, it got service! Then i tried to put a sim from another provider in the mi2 -> no reception. I tried to solve the problem by update to the latest system, it doesn't help. Then i tried to do full wipe and reinstall the system. Still no reception. I think It must be something wrong with the hardware.
