S7edge SM-G9350-NO 4G DATA**I WILL DONATE $50-$100 TO WHOEVER GIVES ME THE SOLUTION**

The exact model is Samsung Galaxy S7 edge SM-G9350 64 GB GOLD PLATINUM
First I want to get this off my chest. I registered this week (I used XDA before like 7 or 8 years ago in high school when I use to flash custom ROMS on windows mobile phones-good times hehe)because I am frustrated since I bought an unlocked Samsung Galaxy S7 edge from a stranger using craigslist on Sunday night. The ad said it was T-mobile Unlocked and in brand new condition with the box and original accessories and it had some pictures.So why not buy it cheap for since I'm using a T-mobile LG-K7 with a cracked screen,right?WRONG!! The phone is working fine except I am only getting EDGE data!!! I found out that it is a chinese variant and it works fine with my T-mobile sim card here in the U.S.A except it can't connect to 4G and that is probably why the shady guy sold the phone cheap to let it become someone else problem I also saw 1 or 2 of these models in the box as well and he said a friend gave it to him and he is just selling it(B.S.) I forgot craigslist had scammer like 40% of the transactions lol, I use to meet these types of people in middle and high school when I bought and sold my used or old T-mobile phones though I never scammed or conned any one.I remember some people would act shady or too nice for no reason,probably cause they stole the phone and were making 100% profit off me.This same guy is one of them.
ANYWAYS THANK YOU FOR READING MY RANT---- NOW ON TO THE POINT OF FIXING THE DATA ISSUE
I am getting unlimited 4G on my k7 and everyone else on our plan is using unlimited 4g just fine.Samsung rep at best buy said its legit and its an international chinese variant and to look around on here to fix the issue. He told me something about the band and t-mobile towers to pick up the frequency. He said I got a really good deal if I can 4g on there. If not than re-sell it and make it someone elses problem. I looked all around google the past few days an either no one has this problem or if they do than the solution doesn't work on my phone.
Here is what I tried so far:
A) T-mobile reset the network connection via tech support
B) I factory reset the phone numerous times
C)I got the right APN settings set on the phone to be connected to nearest towers, a store rep did it for me to make sure.
D) I replaced and used another activated T-mobile sim card
E) I download some apps I saw on here to check LTE signal etc and its running very slow edge
*********I am on the sim status screen and right now as I'm typing this the signal strength is
-61 dBm 26 asu,cellular network type is EDGE,NETWORK is T-mobile, Service state is In service,Roaming is not roaming,cellular network state is disconnected*******
------I hope someone can pick up information off of that and maybe I could change some settings
E) I dialed *#*#4636#*#* and got to a screen to allow me to check phone information,battery information,usage statistics,wi-fi information-under phone information there are options to set preferred network types to: WCGMA,GSM, GSM auto(PRL), CDMA auto(PRL),CDMA only,EvDo only,GSM/CDMA auto(PRL),LTE/CDMA auto(PRL),LTE/GSM(PRL),CDMA auto(PRL),LTE only,Unknown. It will only stay on up to GSM auto(PRL)
....also when I press menu on this screen there is an option to enable data connection and when I click it,it won't stay,it just keeps saying enable data connection
F)I googled what bands this model and it is able to use and it has the capability to be used on T-mobile bands
What else can I do get the data working to 4G right now? The phone is running Android 6.0.1 and won't update to Nouget over the air. I want to root the phone and see if I can install a custom Nouget rom( since the samsung guy said the phone will brick if I try to install the T-mobile Nouget rom or I can't even do it since its an international variant-by the way I am able to have google services on here like play store,etc. so I don't know if that makes a difference to what variant and rom it is because I heard one or the other of hong kong or open china variants for this phone is better and can't use google play)and maybe I am able to connect to 4G data.
Like the title of this post says, I promise I will back up my donation I really don't want to sell the phone unless I have to because I will not get a better deal anywhere ever again for the latest high end phone from a manufacturer

you have to flash the correct CSC this will fix your 4G if you buy an device from a other country than is it possible that you get this problem but when you flash the correct CSC you will get 4G i helped so much people with this problem with a S7 device, i think this your solution
if this fix works for you just keep your money we are developers not for paying

Maybe you should post this in the T-Mobile section.
In my idea this should have 4G data on T-Mobile US out of the box as the required LTE bands are supported by the G9350. Did you check the APN settings? (VoLTE and WiFi-Calling may or will not work without t-mo-rom but that's another topic)
Also you should be fine to flash a T-Mobile US rom as both have Snapdragon SoC. You don't need root to flash an official rom.
Out of curiosity: what about 3G?

Thank you so much!!! People have actually asked through pm to donate to bitcoin first before helping me and here you are helping me first by the way.
I am going to find the correct CSC, what does that stand for? Can I flash a T-mobile 7.0 Nougat rom on my Galaxy SM-9350 first that the person before you replied about(its the link)?? I want to do both to have T-mobile settings and to use the 4G although the 4G is a thousand times more important. If I can do this than I am a happy man!
Why is there a boot loader and modem link attached to every post containing a ROM download? Does that need to be downloaded first,and what are the next steps,if so? I know these are questions I need to search about they are all confusing and mumbled and jumbled up. Even though I registered this week for help I was a member here like 8-9 years ago in high school when I was flashing custom ROMS on Windows mobile phones(good times hehe) but it got addictive,took a lot of my time from studying, and I totally forgot how do things.

Hey I made a new thread today in Q&A for GS7. The APN settings were put in by a T-mobile store associate and it still didn't work. I don't care about VoLTE/Wifi-Calling although I noticed some people on here are worred about that-its just something I never use.
Are you sure I don't need root to flash an official ROM?The Samsung Galaxy guy at Best Buy said it would brick if I used an official ROM because the phone is an international variant. If I can use an official ROM,I can't get Nougut OTA via T-mobile anyway as my phone keeps saying it is updated even though it is 6.0.1. How do I get the offical ROM manually on the computer? Samsung Smart Switch isn't even recognizing my device when it is connected and Smart Switch on my phone looks like it is only suppose to be used to receive files from another phone? I have the link for a T-mobile 7.0 ROM from a post on here that he used on the same exact model I don't know if I am suppose to root the device first or not yet since it looks custom made.
Thank You for helping me out it means a lot you guys are the best! I can already see myself on here a lot in the future doing stuff different android phones like I 8 or 9 years ago in high school on windows mobile phones.

The only data I am getting is EDGE

So, I guess something is wrong.
You can try flashing the designated firmware for this device first and see if this helps. To get the right one (who knows what all was tampered with) use best the Phone Info tool.

I've had this exact issue before, with a Nexus 5 that I bought from Telus, I am with Telus, it ended up being I had to go buy and register a new SIM card, then it was fine, might not be a solution for you but Worth a try,
Actually get a SIM card from your provider, have them register it in the store

What would be the correct CSC file for this device? I tried to flash CSC from a SM-G935t firmware and it didn't work even though she said it didn't matter lol(senior member too)

I'm going to try to find an official U.S. T-mobile ROM and flash with odin...but does it have to be specifically for SM-G9350? I don't think I can find one for that......

Nice, I like what you have! My model is different so I don't know if the ROM will work though I'm almost finished downloading it at the moment. Instructions 3 and 4 is confusing. Don't I need to put superman ROM and CSC file on sd card while the phone is ON?And am I suppose to transfer it on there via usb cable or can I also do it via google drive than open in up phone gmail and put it on sd card? Also do I need to extract the CSC file first to my computer desktop? That file takes forever to extract! Is instruction 4 suppose to be while in recovery mode? Also is it normal for my phone to show "no command" while in recovery mode?

Thank you ?
The rom will work because your phone is exynos based. It got a different model number because it's for Chinese markets. Put the rom on the SD card using whatever method, just do it before flashing the recovery, because your phone may not boot after the recovery to the stock firmware because Samsung has put some crap to prevent using custom firmware. I forgot to say that also before doing anything go to device info - > software - > and press build number several times to enable developer options then back to settings and go to developer options and enable OEM unlocking.
Yes, commands 4 are made in recovery. Install - > pick the zip file and install.
All zip files aren't extracted! The recovery uses the zip file as it is.
Good luck

Were you able to flash the U.S. T-mobile ROM onto SM-9350?
The official firmware can be found on https://www.sammobile.com/firmwares/database/SM-G935T/

I found it yesterday but their free server is under maintenance so he will have to pay to just download a firmware file.
I don't know why don't samsung provide them for free on their site!

Got a new vibe, has Vibe UI v2 installed. Can I get stock?

Hi all,
My old vibe died and couldnt find a better phone on the market since 2015 so got a new one. However I dont know what the heck is installed on this one.
I have never rooted before but have a cs degree so im not out my league. With the details in the image below, do you know what I can do to get stock installed?
The phone has a trojan application called fun weather and i cant remove it. Have done everything from root access to hard deleted. But as soon as i get wifi again it downloads. Are all custom roms like this so the developer can make cash? I also dont know if this is ROW or China. It has google services installed.
VERSION AND DETAILS SCREENSHOT HERE (2K image here fills the whole browser.)

Regardless apprecaite the help here.

Help: SM-G9500 3G/4G in Europe

Hi!
I just got SM-G9500 (bought in Taiwan), and internet is not working, I believe have tried everything in the settings. Phone unlocked, LTE sign next to carrier on top is there, everything else is ok, except data network. SIM on other phone (S7) works fine. Yep, me located in Europe (Vodafone HU).
Is it possible to get 3G/4G with this phone with my operator? If yes, can one point me to the direction how to achieve this?
Baseband G9500SQU1AQC9, Kernel 3.18.30-10318693, Build version SEPF_SM_G9500_5.0.2_0008
Please help!

Do you mean G950F? ie a S8. if so just go here https://www.sammobile.com/firmwares/galaxy-s8/SM-G950F/ (you can find S8+ too if that's what you meant), download the right files for your country & mobile operator, and flash via ODIN

Well, I just posted a link where you can see that there are only two countries listed ... or differences in S8 models (and processor) does not matter, so I can take any S8 file? ... I am aware of this principle, but dont see anybody did it in similar case as mine (or with G9500).
Still waiting for opinion/ideas...

Yeah it will make a difference, that phone is only for far-east markets, hence the firmware, you can try the Hong Kong version, but I wouldn't hold my breath. Far east models run very different frequencies on their modem I believe, could be wrong though

you don't need to flash anything.
you have a Galaxy S8 (SM-G9500)
your phone "speaks" all known wireless frequencies (from the factory) & it can be used anywhere in the world.
The LTE icon just means your phone is registered on the LTE network.
It doesn't (yet) mean you have internet access.
you're 1/2 way there.
at least your LTE works.
You need to contact Vodafone HU helpdesk & ask them to give you the "Access Point" details for their network.
** Normally network providers send you these details in a text message - the first time the phone connects to their network - but maybe you didn't accept the settings / deleted the text message?
Once you have the settings:
Go to: Settings / Connections / Mobile Networks / Access Point Names <--- select "ADD" & then enter the details provided by Vodafone HU & save the access point details.
Your internet access will work after a couple of seconds.

From hungary too
Hy, I'm hungarian too,and i'm just writing in english because of forum. I bought also an SM-G9500,and i still didn't get Oreo. Or any softwer updates since january. If you want, search me on facebook, Gyarmati János István.

S8 plus ussd problems, call forwarding

Hi first post here but not a complete newbie. But this time I'm stuck big time and would appreciate some help.
I've got a s8 plus that recently started playing up. All of a sudden it started not being able to make or receive calls. But I noticed it only happened when the "conditional call forwarding active" message didn't appear when dialing. I figured it had something to do with call forwarding so try to change the settings on supplementary services settings but when I tried to enter the settings an error message appeared "failed to read data" I tried sending the code manually to cancel voice mail *#022# to see if it would work but I got "connection problem or invalid mmi code" so assumed it could be that the phone is trying to check with the network the forwarding settings as the call starts but for some reason it cannot communicate with it as the mmi codes don't seem to working?? (I'm not that knowledgeable in that area) I tried all the fixes online for the "connection problem or invalid mmi" but none work so I flashed the firmware through Odin even tried a few different ones, I've been playing around with Odin for a while so I'm comfortable with it, I even flashed a pit once for a note 4 that was bricked (just saying so you can see I'm comfortable with using it, not an expert just comfortable) but nothing has fixed my problem my phone is a g955fd running pie and one UI with the latest security update. I've read the duos have some issues with this. I've tried other sim cards on my phone from different carriers and the problem is the same and I'm using my sim on a borrowed phone and no problems. I'm assuming the problem goes deeper than the firmware, could this problem be boot loader related? Would a nand erase and reinstalling the boot loader fix it? Everything else works 100%
Someone please help me, the phone I'm borrowing is an apple and every day I have it I feel weaker and dumber, it's like kryptonite.
Sorry for the long post but I've been browsing xda forums for years and I know that you guys always say to share as much info as possible. By the way I've searched and couldn't find a thread about this but it there is one I promptly apologize and just ask for the link to it if not thanks in advanced.

? G935F or G935U exynos vs snapdragon
Way for snapdragon
Flash https://forum.xda-developers.com/galaxy-s8+/development/rom-t3901074 with odin and test with hard factory reset recoery.
After, flash odin last firmware stock sammobile

Thanks
Thanks for your reply deadedge7
As I said my s8 + is a duos g955fd variant and has an Exynos processor, I'm not sure that rooting it would make much of a difference, as to my understanding rooting doesn't really change the boot loader it just allows you to install a custom recovery and roms. Which is not much different to reflashing a stock rom for all intents and purposes , but I might give it a try anyway. I guess that maybe a rom like the one in the thread you shared might give me some more hidden codes access as a root but I'm not sure. I will try to find a root like it for my variant unless you know of one and can point me to it.
Thanks

Hard reset or flash stock software or hardware problem
For iemi best way is root efs with flash twrp best way for /EFS

No solution so far. I've rooted the phone and install a couple of custom ROMs but still nothing. I'll try and roll back the firmware and see what happens. I'm no expert but I still think it is fixable. If I find a solution I'll post it on this thread. If you find one please share. My solution at the moment is getting a galaxy A50, very comparable performance with the S8 and really cheap.

I'll keep that in mind. Couple of things to note: I don't get the message conditional call forwarding active. I don't think I ever have.
I tried a different carrier SIM card(T-mobile) and it worked (I'm on At&t). I was able to make and receive calls. Even tried an out of country SIM card and received calls. But my At&t SIM works on other phones perfectly. Go figure lol.
The only other reason I can think of is maybe cos it fell a couple of times from the couch. About 1.5ft. New case kept making it slide off.

Hi guys,
I just gave me iphone xs max to my wife since her iphone 7 is already too buggy and slow. Now that I moved to s10+, I love it and but the customization option is overwhelming me. Happy though that its customizable.
Then I realize 1 critical thing. I bought a snapdragon USA version of AT&T from local importer. I am located in Asia. When I looked at the software version, its only at "G975USQU1ASD3" with security patch, March 2019. I tried for 2 days now to get the OTA update and it just wont come. Saying that I already got the latest update.
Naturally I checked google and found so many updates, and one of them, night mode in camera, I really want. Now I am a newbie in all of these. My question is.. how do I get the non OTA update? I don't have a PC, but I might be able to use my work PC. I do have an micro SD card.
In summary:
1. Where to find the update files? the non OTA version
2. Is it doable without PC?
3. Can I just jump to the latest firmware update, or do I have to do it manually one by one?
4. Will it wipe my phone, because I spent hours customizing it before checking the problem.
Thank you very much if there's anyone willing to help me figuring things out.
regards,

2.You can use work PC but need get small software named Odin and samsung drivers for correct work
3.You not need install one by one you can flash directly to latest one but must use HOME_CSC and make backup with samsung app named smart switch which is already on phone if not you can get it on Google Play Store

Hi, check the thread
https://forum.xda-developers.com/s10-plus/how-to/guide-g975f-flashing-megathread-faqs-t3936704
there are answers for all your questions=)

thank you very much guys!
I need an urgent help however.. I changed my csc to SPRINT from ATnT, using *#272*IMEI number# method. I kept changing to T mobile, and all, until I got stuck with SPRINT.
Now I tried the *#272*IMEI number# method and it won't let me do it with SPRINT CSC.
HELP please ( I just want to go back to ATnT or T mobile again..

To try and force a change of the csc power down your phone, remove the SIM card and boot up your phone without any SIM inserted. After the phone has completely booted up insert your SIM and you should get a message that the network settings are being updated.
I purchased an unlocked AT&T S10+ as well to use on T-Mobile. Since you don't actually have AT&T service I would very strongly recommend that you flash the U1 (unlocked) firmware. There are instructions for doing this in another XDA thread.
AT&T firmware is modded specifically for their messaging, network and WiFi services. Since I'm not an AT&T customer I got no OTA updates until I flashed the U1 firmware. Immediately after flashing the U1 firmware and booting up OTA updates were available to download and I receive OTA updates when they are available so there's no further need to manually flash updates using a computer.
The current U1 firmware has night mode for the camera and was just updated this week to the August security patch (which is good for Samsung).

Hi thank you very much for your help. I appreaciate it. However, as you can see from my opening post, I kinda did a mistake and locked myself out of AT&T now.. I am stuck with Sprint after changing CSC 3x feeling safe.. then Spint removed my ability to change CSC via *#272*IMEI#
:crying::crying::crying:

You shouldn't need to change the CSC using the dial code. If you cold start your phone without a SIM card then insert the sim after your phone has fully booted up you should get a message about your network settings updating.
I would also still recommend flashing the U1 unlocked firmware.

Hi thanks again for replying to me. I tried many times doing this but as soon as my SIM card got in, SPRINT OMADM took over.. I can't even get rid of the notification.. sigh..

This might help:

That's apparently something annoying that's specific to Sprint.
To get rid of any US carrier stuff on your phone I would still suggest using the modified Odin (which can be found in the XDA firmware flashing threads for the S10+) and flash the U1 firmware version which is carrier free.
