When I buy that phone S6 Dues (G920FD) default was 5.0.2 and I can use 3G without any problem. After that there is one oTA update and my 3G has gone. After that I have decided to use Stock ROM but no improvement on mobile data. I have to select GSM for both the SIM and 2G is there with slow connection. Whenever I select WCDMA/GSM for any one of the SIM, immediatley it shows "Emergency calls only" and no mobile data. Wired problem but is there any solution for that? Same IMEI shows in *#06# and back side of S6. But in IMEI.info and mobile info app shows invalid IMEI. Dont know what is the problem.
Try flashing stock 5.1.1 ROM via odin specific for your country.

OK. My first stock rom was from Sammobile and the issue was the same on that. Now I am using |ROM|★ARCADIA v1.0★|►5.1.1 XXU2BOFJ◄|JULY.25.15|★ and issue has no improvement.
I bought a Note 5 which worked fine with China Unicom, the phone was 5.1.1 so I decided to manually update the phone to mm. After the update the phone can make calls, but it can't pick up data signal. I've tried everything from flashing the modem back to 5.1.1 (which was the one that worked, originally) but no dice. I was wondering if anyone had a solution to this. The phone isn't rooted and its constantly trying to activate its voice and data, even though the voice all ready works.
Enter the APN settings manually for your network. The same happened to me on my Unlocked N920P. I entered the APN (Airtel India) and deleted all the others. On upgrading, it will automatically pick up the Sprint APNs. So add a new APN and enter your setting for your network manually.

It happened to me too. The first step was the APN. changed the APN manually on mine but still it seemed no data connection was active. On step two I discovered that even the data seems not active, in reality there was a data connection and everything was working, but the icon was not showing due to something missing in the Sprint's SystemUI data connection icons.
So, try to put your apn manually and try and check if there is a data connection, i.e. using the browser to navigate.

Open the notification panel - touch the "down arrow" symbol on the upper right corner to show all the icons and look there must be the data connection icon you're looking for.
As for the update: Updated myself to MM and everything works fine with the exception of 4G. This is not something caused by the update but because the LTE-4G bands the phone works are not compatible. Check yourself @ willmyphonework.net
Flash pure GSM kind of roms.
First go to official MM by ODIN, root it,
Via TWRP, flash Lamlazy ROM or aurora rom which is compatible rom without sprint stuff.
Try this rom http://bbs.gfan.com/android-8394771-1-1.html

I didn't try yet. but it says N920p supported. If u are on sprint, am not sure how it works.. but GSM should work well.
That V7 of Lamlazy can be found here -- thread http://forum.xda-developers.com/show...&postcount=153
Hello, I can't connect to my local mobile network anymore.
So I can't call or receive phone calls.
I am in Latvia, Baltic region.
My imei is legit and working, so is my phone number.
When I search for my mobile network it finds it -LV TELE2, easy, but when I attempt to connect to it, it shows it 'can't connect to this network try later', when of course the network is working properly for other phones., and it is the network that worked before.
I happened after I flashed a custom lineage rom. It was the right rom for my device,
and I flashed it in correct order and all worked except mobile networks.
I thought using odin to flash back the stock rom will fix it, but it didn't.
Now I am back to stock 7.0 , flashed csc SEB version for my region.
Now in mobile networks there is only Lte/2g/3g options, why there is no gsm or vcdma mobile service?
I believe my provider is gsm, so how to restore it so I could call again?
It shows no service in the drawer, and can't connect to my carrier.
Any help is greatly appreciated, thank you ^_^)/
Had same problem after my motherboard was changed in some mobile repair shop and old imei and stuff copied from old motherboard. After flashing stock 7.0 with ODIN, I had same problem. Luckily repair guy added some certs back free of charge. Something to do with not being official Samsung repair place and not having right kind of tool.
Sent from my SM-G920F using XDA-Developers Legacy app
Thank you for your info. Then it must be possible to fix it with the right tools even at home! I am sure there must be someone who knows how to do it and can help me, and many others with the same problem.
When you tap *#0011# imei status is OK or NG?
Hello, I typed *#0011# and yes imei status is ok, more info - rat=gsm (2g), band=pgsm900 and reg status is = not registered.
So this couldn't be an imei problem, could it?
During this time, I tried many roms, nougat and marshmallow, official and custom, but none has fixed it yet.
I was thinking, flashing original galaxy s6 lollipop rom will definitely do the trick,
because I remember I had a similar problem with my old galaxy s plus phone,
it was impossible to connect to any mobile network on any rom,
until I flashed the oldest stock rom for the device.
But the problem is, I can't find a working download for a custom lollipop rom, they are extinct it seems,
and the official lollipop rom can't be flashed with odin, obviously, because I have a higher fw already.
Official lollipop would be the best and would show if the problem is software related for once and for all,
but how to install it when knox and all kinds of binaries doesn't allow me to flash it with odin?
Is there another way to do it?
No need for this anymore, never solved the issue.
I sold the phone.
Thanks anyways ^-^)/
Please help me.
My S7 duos (G930FD) doesn't accept official stock updates or custom ROMs. If I install any of these, my phone gets stuck on "EMERGENCY CALLS ONLY" unless I return to my nandroid backup. I upgraded to Oreo and had no network at all. I searched for new networks but found none and even sometimes I could find my network, if I try to register it, I will get network not available. I also tried some custom ROMs and had the same experience. Its like I only have to remain on my official stock ROM. Any attempt to upgrade ends us frustrating as my phone will never get network. Only thing working will be WiFi. I can't use nougat custom ROMs as well as Oreo ROMs. No upgrade at all whatsoever as my phone will completely lost network. One time I upgraded to Oreo and tried to do a restore of my EFS but yet nothing positive, I even tried to patch the network with Z3X box but all attempts went in vain. Am so confused about this situation.
Please I need urgent help.
