I upgraded my Micromax A120 to rainbow and then to cyanogen mod. the cell network stopped working. then i went back to stock firmware but the cell network is still not working. i have tried using both one and two sims. i have tried waiting for 10 minutes after booting for the network to come but nothing. the network is in India. Please help.
I guess you have lost your IMEI... try *#06# to check whether you have a valid IMEI or not...
Thanks. i used mtk droid tools for changing the imei and it fixed the problem.

Hi. In turkey they do not allow foreign phones, so i stayed there for week and changed my imei through xposed module called IMEI CHANGER. After that i couldnt register on network, so i stayed there without 3g for a week, only wifi. But yesterday i returned to my country put in my sim card, can receive calls and sms. But no mobile data. I flashed different modems, flashed back to stock, but nothing. If someone has cure please share

Pardon if it`s obvious, but did you make sure the APN settings were correct again?
Yeap, that is one of many things i`ve done to get mobile data back
Guys, please help. It`s been 3 days i`ve tried many ways but still no progress. Flashed nb1 stock rom. Tried different modems to access to service mode, which i think problem is there somewhere. When i press back and then input 1 it says menu does not exist. On some pages guys say that its modem related so flashed mf3 and mk2 modems still nothing. Please help. Everything works but no mobile data
Hi, Yesterday I tried installing the Global dev ROM. It worked fine for a few hours. Then I went out to run some errand and as I was returning my phone fell down and rebooted. After that it started showing SIM card not inserted and a error msg saying device ID not valid. Then using MiFlash flash all method I flashed the global stable ROM. Now SIM is detected but I only get 2G signal and no 3G. Also I cannot use data. My device model no. is 2014818. My IMEI number is intact. Please help.
i recently got a note 4 N910H 6.0.1 for repair, the problem is that the phone connect and register on network only for some seconds and then it looses the connection and stay on this loop, what i have tried so far :
-Different ROM
-downgraided to 5.1.1, back to 6.0.1...
-Different Kernels
-Changed network mode :
* LTE/WCDMA/GSM(auto connect) : still on the loop (Connect, Disconnect)
* WCDMA/GSM (auto connect) : still on the loop
*WCDMA only : no loop and no network either
*GSM : no loop and no network either
-Mannualy selected a network : I can find all availble networks but i got error when trying to register on ...
-What i figured out : IMEI is not the same behind the battery and when i type *#06#
My customer said that the phone was working before and everything allright and that the phone was used when he buyed it
My guess is that the phone is blacklisted, but i want to be sure before givig feedbacks to customer , so anyone have an idea ?

I think this is not software issue.
Maybe radio antennas or sim slot is damaged.
I also bought a sprint note 4 n910p before and it was running n910f software and when i flash sprint official firmware my imei was changed. 1st when i bought imei was n910c but afrer i flash sprint imei was sprint galaxy S5..
Point is that my sim and signal was working fine even when imei was changed.
Go to note 4 exynos thread and flash n910c rom for n910h and see if it works.
