I tried something new and I have interesting results.
I installed a Firmware U, it is a version of android 7. I installed it by odin and everything well without problems. When I restarted I put the SIM and it told me that I had to restart to configure the options of my operator. It restarted without problem and to my surprise it CONTINUES without Signal. In '' Access Point Name '' the APN of my operator's MMS has been created ONLY and AUTOMATICALLY. I did not set it up, it came out alone.
I still do not understand what problem this phone has. There are several people reporting similar problems with the upgrade to Oreo even in other S7 EDGE models.
Any ideas?????

Do you use a Custom ROM?
Did you tried a factory reset?

yes i didt reset and hard rest
Are you using a custom ROM? I faced the same issue when updating the stock firmware trough Kies. I had to download the official firmware and flash it with odin instead of just using Kies, solved every problem.

You are not telling us much about the story of that smartphone. What build are you running? Have you tried flashing in the past? Was it broken since when you got it?
flash the stock firmware using odin or smart switch
Thats a Verizon Galaxy S5!! What country are you trying to use it in? While the GSM sim-slot on Verizon high-end devices is usually unlocked for Global GSM usage, you need to check if the device supports the GSM frequencies in your location.

[Q] Help! S7 Edge SM-G935A Andriod 7 Nougat update data not working

Hi ,
I have a unlokced at&t s7 galaxy edge and I was using it till yesterday on Tmobile network
every thing was working fine till this andriod 7/ Nougat update came in.
As everybody else I was very excited and let the phone go thru the udpate, everything went fine and I got andriod 7.
However after the update for some reason only mobile data ( I can make/receive calls) is not working on Tmobile network.
1. put the SIM into another phone to check there is no problem with the SIM/network outage. We found that there is no problem with sim/account and data/voice everything works exactly as it is supposed to work with another phone
2. I rechecked all the settings/apn/data/ etc many times on unlocked galaxy s7 edge phone but data is not working. I still see 4g/4g lte icon but I don't get the data. we tried manual search/resetting of network as well
4. I have put my brothers AT&T sim in on same unlocked galaxy s7 edge phone and data works fine.
can you please help me, advise what are my options now ?

What firmware were you running when you installed the OTA update? You may wanna try manually installing the full T-Mobile or AT&T Nougat firmware with Odin, just to make sure everything matches up?
Edit: hmm, if your brother's sim works in the phone, then everything might be ok. But still, installing the full firmware by hand won't hurt. This is weird tho lol
Ok, cool. I will search for it and try that out and post my results. Thank you!

Update SM-G935FD Dual Sim to Android 7 ?

I bought this phone from the USA about year and a half and I'm using it in Macedonia, Europe the whole time. It is a dual sim, but I'm not sure which country it is exactly from, Taiwan maybe I guess?
The model is SM-G935FD and the Baseband version shows: G935FXXU1APB6.
I tried updating it manually, but always says you're using the latest software version even though android 7 has came out a long time ago.
Can you tell me:
1. How can I update to android 7 ?
2. Why am I not receiving an update automatically, even though this feature was working when I bought the phone. I was getting regular updates automatically ever since I bought the phone up unti a point when the 7 came out.
3. If I update the firmware through an SD card or whatever method you suggest its best, will I continue receiving regular updates automatically after I install the v7.0 ?
4. How can I check what country is this phone from?
Lots of questions, would be glad if someone can clear these things up for me so I can understand better how this works with samsung and different countries models etc.
Thanks up front!
try smart switch on PC to update it... frend of mine had s7 flat and no update via mobile phone, as soon as I connected it to pc and turned on smart switch update came out...

I wanted to mention that, but I've probably forgot. I did try Smart Switch, but it also said, latest update already installed. Any other ideas?

I'm sorry for my noobish questions, but can you please explain to me how to choose the country of my firmware? Do I need to choose a country which I currently reside in? Or do I need to choose a country for which the phone was made? I just want to use English language, even though I use it in Macedonia, Europe.
Please kindly advise. Thanks!
1. How can I update to android 7 ?
i had the exact same problem as you smart switch n ota both said i was on latest software. All you need to do is goto sammmobile download firmware for your s7 edge model if your phone is non carrier or unlocked then you can download any carrier version. after that download Odin n Samsung drivers n view an odin flashing tutorial on YouTube.
3. If I update the firmware through an SD card or whatever method you suggest its best, will I continue receiving regular updates automatically after I install the v7.0 ?
I am getting all the 7.0 updates.
4. How can I check what country is this phone from?
if i remember correctly Its written on the smartphone box although u don't need to worry about the country all you need to know is the model number.
But to tell the truth there is no performance difference only ui change but still if u want to be on the latest version then use Odin. good luck.
I have flashed my s7 edge about a dozen times n haven't faced any flashing problem just be sure to use original cable n try not to use the computer while the flashing is happening. use odin in adminstrator mode n if possible kill extra background processes like chrome etc (not needed but i still do it just to be safe)

Just checked my phone with PHONE INFO app and there seems to be no CSC code?! All these field are empty:
Original CSC Code: blank
Firmware CSC Code: blank
Active CSC Code: blank
Available CSC Codes: blank
CSC Country: blank
I tried dialing *#1234# and it says:
"USSD code running"
but it shows some kind of error right after:
"connection problem or invalid mmi code"
and does not enter the menu with the CSC code. Tried restarting the phone, switching sim cards and what not.. Nothing worked and I have no clue what my CSC code is now.
My original box is gone and can't really see what country it was made for, but as far as I can remember it didn't say anything on the box. The title of the original amazon.com listing says: Internationally Sourced (Middle East/Africa/Asia) Version G935FD which doesn't say much.
I don't know what to do, I'm a bit scared to flash it with just about any country firmware. There's got to be a way to find more about this phoe CSC?

Download cpuz app from play store. From the app you will find what is your phone chipset. If it is exynos download any 935fd nougat firmware and flash it with Odin.basically 935fd is a unlock version. it's support all csc version and you will also get update how much I know.

SM-G935FD wont connect to network/carrier after routing to Nougat 7.0 with odin

Please someone help me, i was updating my s7 edge duos to 7.0 after that i cannot join network, wifi works well and got signal also but cant connect for some reason shows Emergency Calls Only i tried many roms and with every single i got no network, nothing helps.. when i check dial 06# my both imeis are OK and nothing is wrong with it..
maybe i flashed wrong modem or something and how can i repair it now? please help
Provide more details of your phone , are you using original stock rom ? Or rooted custom rom? You may try changing sim , or wiping cache partition in recovery , if that doesnt work only option is factory reset, also tell if your update was successful without errors ? And use the same firmware as your current region , and also check if your phone is carrier locked , then you need to unlock it to work or use the same carrier firmware.

Hi Bachimpek
Seems like you need to patch your certificate , try to downgrade to 6.0.1 and see if phone can connect to network if that doesnt work then you need to patch your certificate with a box like "z3x" or "octipus"

So , you want to downgrade ? Just download a complete firmware file with all files included and flash it with odin, it will downgrade , if it solves the problem , maybe stay with it instead of nougat.

Don't seems so , you need to repair it in z3x or octoplus box , but if network was working well before update to nougat , it should work when you downgraded again to 6.0.1 , so i guess its some certificate issue , but you may check some setting and try to search networks manually and try changing network type to 3g/2g , 3g only , 2g only. Also try checking different sim cards. If it did'nt fix then you have to repair by box. Good luck

Hello, same problem samsung s7 edge SM-G935FD. restarted my phone and no network. My region is Lithuania and i cant find firmware of my country, what to do ?

SOLVED

Hello everyone
So i got AT&T note4 SM-N910A on a good deal about 135$ yesterday and its unlocked running on android 5.0.1 lollipop i just want to flash 6.0.1 marshmallow stock via ODIN but i afraid if i flash another stock rom it will get network locked and i know deep down so far this thing is not rootable. so please anyone know exactly is it safe to upgrade from 5.0.1 to 6.0.1 without messing anything up because its running a modified firmware with lot of languages included and all blotware/bootanimation/tethering hotspot unlocked etc from AT&T removed.
Here are some screenshots to help understand the device i got.
TIA

Thanks for replying
Yes indeed odin is harmless but my only concern was sim network lock because i have usa AT&T note 4 and i live outside usa .
previously i had sprint note 4 and i flashed stock via odin and it got network locked it was showing "invalid sim" but this doesn't happens with Tmobile/verizon/AT&T thankfully .
thats y i thought better to ask and take advice in xda.
Have a good day:good:

Now that you mention it, I did get that error on my T-Mobile Note 3 a while ago. I upgraded to the latest version via Odin (I also live outside the US) and the phone is unlocked, but I kept getting invalid T-Mobile SIM inserted and didn't get any data.
Fortunately, my plan wasn't to go back to stock, only to test GPS (Google Maps) on stock. After that, I went immediately to a custom ROM and did not get that error any more.
Hope you don't get it xD
Good day :good:
