[Q] Not receiving calls

I am really tired of the same situation, please help me.
My 920I Galaxy S6 has stopped receiving calls, either if I am using the phone or it is locked I won't receive any call, I have to restart my phone to get the messages of missed calls and call them back. I tried many different modems, bootloader, roms and firmwares and nothing has worked. Also, I tried both on WIFI and 3G/4G and it doesn't work.
PLEASE, I need your help .

Ensure you flash the CORRECT modem. It's a common modem problem.

Firmware for SM-G930F

Hi,
I do have an unlocked version of Samsung Galaxy S7; model SM-G930F(international model), which I brought from Jet.com. I am using T-mobile sim prepaid sim on it.
For the past few weeks its showing problem of re-starting and hangs on Samsung boot screen(first screen with Samsung name and galaxy s7 logo) with blue light on top always on. I tried factory reset, but did not work and happens too often these days. There is no fixed way of getting out of it. Sometimes it works by clearing the cache, at times by logging in on safe mode and rebooting, then at times by charging for a while and turning it on etc...
From looking into the forums and discussion, I have the feeling that its related to bootloop or bricked phone. The only thing left to do is install firmware once again with ODIN. But I am confused on which firmware to download. Can anyone help me with which is the best one to install? Below is the phone details.
AP : G930FXXU1BPLB
CP: G930FXXU1BPJJ
CSC: G930FUUB1BPL4
Any help of this is much appreciated.

you should install all of them, in the order it says,

OK. But do you have the link to the firmware that I can use? I am not sure from the above information which firmware would be suited for my version of Galaxy S7. Looking for the downloadable firmware.

Hi mate
You had a Marsmellow firmware you can basically flash any official firmware you want , as long as it belongs to a G930F , pick a country similar or same to where you live
Check here
Get a Nougat firmware they are working fine, follow the intruction in how to flash , pick CSC or home_csc , CSC will factory rest your phone will it leave it like new , if you use home_csc has to be same as the one you have your phone then you will not lose any data

SM - G930F
Thank you!!
I got the file downloaded now. Do I need to select all the AP, BL, CP and CSC on the ODIN software to reset it?

Today morning again the phone got hanged in the bootscreen. So, I decided to run the ODIN3 with all the 4 files selected. I installed the Samsung drviers and followed all the instruction and run the application with all the 4 files selected. The process showed success in the ODIN3 application. But even after that, the phone is stuck on the bootloader Samsung with Galaxy S7 logo.
Any idea what to do next or how to resolve this issue?

Did you factory reset from recovery and flashed firmware again?

Perhaps someone can answer a similar question for me? I have the XEU nougat beta firmware, can I flash the BTU final nougat without needing to factory reset?

OK.... here is the SAD news.. I gave the phone for repair on a local cellphone shop. They did some testing on it and said its related to software. After trying to fix it with installing software and other fix they called me a while back and said `THERE IS NO FIX FOR IT`.
Not sure what to do with it. Bought this unlocked only 6 months back and its already dead....
Never going for another Galaxy for sure.

Yeah, you can do that, but is preferable to do the flash then a factory reset...

Verify whether your IMEI is still intact.
Go to:
system settings>about phone>status
or
system settings>about>status>information
or
system settings>about>information
Or whatever similar settings that you have, then check to see if your IMEI number is shown.

Thanks for your replies. Yes my IMEI is there but its not the same as it is on the back of the phone. However, the first time i flashed the stock ROM it was all the same but i still had this problem of Network not registered.

Are you sure that you flashed the correct firmware for your specific model number?
Have you tried another SIM? If you had the SIM in when you flashed it, it might have damaged the SIM somehow. That might not be your issue but it's worth checking.
Maybe you have conflicting data from before you flashed it, in this case you can try bioting to recovery then factory reset and wipe cache then reboot.

Yes i used the exact firmware for my model as well for my country. I think i have done what you proposing already. And for trying a different SIM i did try it too. I am really helpless right now

S7 Not registered on network issue

So I recently bought an S7 and was happy with it, until I got hit with an FRP lock that wouldn't let me boot. So I flashed the stock ROM from sammobile, this fixed the boot problem but now I can't use my phone to call or text, I can only use wi-fi, I have "emergency calls only" displayed where the network should be... I have tried reflashing the ROM several times, different modems and no luck, I also tried smartswitch which also didn't help. I have no clue what to do now. :crying: all similar threads about this are old. Someone pls help me.

You must flash the correct firmware for your device.
