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

Thanks I did that yesterday already and it still didn't work
I am a member because the owner hates the Iphone and I respect that

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 am a member because the owner hates the Iphone and I respect that

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......
I am a member because the owner hates the Iphone and I respect that

1) Download this https://dl.twrp.me/hero2lte/twrp-3.1.0-0-hero2lte.img.tar.html and WAIT.
2) Download superman ROM: https://www.androidfilehost.com/?fid=817550096634750162
I choosed this rom cause it got nougat bootloader and kernel. Also download CSC chooser zip: https://www.androidfilehost.com/?fid=745425885120710484
3) Install twrp via ODIN and uncheck auto reset in odin. Then press power + home + volup to go to recovery. Put the superman rom and CSC chooser zip files on Sd card and put back in phone.
4) Install Superman rom,in aroma pick superstock kernel 'samsung pay and knox work' and install/update everything especially the bootloader. In mods stick to stock as possible.
5) Install the CSC zip file and choose t-mobile USA.
6) reboot and pray everything works LOL
I'm not responsible for any damage that might occur but if ir worked donations are welcome to help a medical student here

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!

The problem is the APN and you can not modify it. Contact your carrier and see if they can assist.

ehrn i purchased the phone it was perfect. connecting internet was showing 4g.. but when i installed this original Verizon rom it became difficult.. now i am unable to root and install custom recovery... please guide me to root and install custom recovery TWRP and i want to install custim rom.. please help

@dipankar.c2bs
You might look into getting your CSC "sales_code" changed. I'm not sure if that is entirely the problem, but it is likely related. Even the USA Verizon ROMs come preloaded with databases that are used to provide custom parameters for a variety of carriers and locations world-wide. (See the file /system/csc/imsprofile.xml for example) I suspect the way this information is actually used is through the "sales_code" CSC value, but I'm not 100% sure of that.
I'm guessing you want "INS" or "INU" instead of VZW
What you currently have:
Code:
getprop | grep -i csc
If your handset is supported by Airtel, one of their technicians will probably know how to do the CSC change, possibly without even rooting the phone.
If it not supported, they probably will be under orders of their employer not to help you at all. But, is is easier for them to give you advice face-to-face, rather than over the telephone (subject to monitoring), if that is possible.
A question to ask - a form of social engineering - is this: "do you know of someone in the area that can help me for a small fee?"
[EDIT]
There is one other possibility for a non-rooted phone. I really don't know if this would work (I am speculating here), but the basic idea is to apply a CSC for a closely related device Model (a SM-N90???? Qualcomm model, hopefully for CDMA/LTE) that is for your country and carrier on top of your existing ROM using Odin. Get the CSC file from Sammobile, and:
- wipe the entire phone using the stock recovery. (You can remove the external SD card first if you like)
- boot the phone, shut down, boot into stock recovery.
- wipe the entire phone again in the stock recovery
- boot into Odin and flash the CSC in the CSC slot.
- boot the phone; do a minimal configuration and see if you have the service you want.
Note that @donc113 s advice given above is the right place to start: ask your service (Airtel) to help you before you try anything yourself.
good luck.

when i purchase it was good... there was 4g indicator also.. no verizon boot screen.. but now it dont works..

One of your friends who installed the stock ROM apparently didn't understand the consequences of what he did. Stock ROMs set the APN for Verizon. Did this friend happen to make a backup before he did the ROM switch?

G930P to G930T

All,
Apologies in advance if this has been answered (I think it has, but I am being cautious here). I've seen a couple of posts that seem to indicate that this is indeed possible and relatively easy. Wanted to see if I could get confirmation before attempting this (seems too easy).
Full disclosure: this phone is not rooted. It is unlocked and I'm currently using it with a t-mobile sim, but the sprint activation app continues to cause problems and requires it to be force closed. I'm also now having sporadic issues with LTE connection. Double checked all settings with regard to t-mobile configuration already. Thinking this might be the best way to go at this point. I'm not interested in rooting/unlocking the bootloader unless absolutely necessary to do this.
Based on my research, it would seem that I could simply download Odin 3.12.3 (https://forum.xda-developers.com/showthread.php?t=2711451).
Then, use that to flash the flash the files found here https://forum.xda-developers.com/tm...o/g930tuvs4bqc1-odin-files-3-25-2017-t3579177.
Any guidance would be greatly appreciated. Thanks in advance!

Anyone have any suggestions?
Thanks.

Anyone? Don't all speak at once.
Thanks.

If it is unlocked, odin the tmobile firmware. It will unlock the correct bands. You can also flash the universal firmware and get the same thing without the bloat

Im having the same issue. Another thread suggests the universal version then flashing something else to open the bands we need. Those 5 download links you shared, are those all tmobile stock? Ya id love a tutorial lol

I decided to try this today using the files I originally linked and everything appears to be working just fine.
Thank you, lvpre, for the reply.

Hi, I am currently trying to find a way to enable VoLTE and wifi calling/text on my unlocked S7 Active. This issue is that this phone is exclusive to AT&T and I'm using it on T-Mobile. I stumbled across this thread and saw that you had success with this and the unlocked S7 Edge. Would the methods you used also work for the unlocked S7 Active running on Tmo?
Apologies if I'm in the wrong area of the site. I'm a complete noob to thIs community and the rooting process itself. I have made one post so far asking some questions regarding this topic over in the S7 Active root section. Received a very kind and thorough response (still need to follow up and thank him!)
He did say there are ways to enable VoLTE, but I'd have to research the topic to figure it out. And that's how I ended up here
Thanks so much. Very grateful for any insight.

Thank you guys so much for the direction! I checked out both links. The last one (17-18 pages) looks quite useful, but just after reading the first page, it's very clear that I need to start from the beginning. It was like trying to read a foreign language.
It would probably be safer for me to try to find a beginner's intro to rooting and basic tutorial first.
Hey, you guys should set up a mentor program! I know I would gladly fork over a reasonable donation for some one-on-one schooling
Edit: I have bookmarked the advised links too. Will be returning to them as I become more versed in all this.

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

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.

Install (Phone INFO SAM).apk
check csc if they are all the same operator
