    I just upgraded my samsung note 4 from 5.1 to 6.1 installing Dr. Ketan rom. after installation everything went well but i realized a circle with a line at the position where my mobile network signal icon should be. I have tried inserting different sim cards but none is detected by the phone. Hence i can receive or make calls or even sms. All other functions of phone are ok. Even went through settings and realized the mobile network menu in settings is absent. Please i need help on how to arrange this problem.

    Try reflashing the stock ROM - see [Samsung] How to flash Stock ROM via ODIN. If that doesn't help, the phone will have to go into a repair shop to have the SIM port replaced. Once it's working, you can try the Dr. Ketan ROM. (Assuming that your phone is a 910C, 910H or 910U - it probably won't work on other models and you'll have to stay with the stock ROM.)
