How to unlock gsm on 4.3

Hey All
right i have just ordered this sprint s4 Blue from ebay for personal usage internationally
Suppose i get the phone on stock 4.3 , can anyone outline the exact process of how i can get this one to work on international GSM networks.
My fault that i didnt ask the android version from the seller.
with what i have learned : this is how this can work
1.. run knox removal script, i mean remove knox files ( as the phone will be used internationally i am not worried about the warranty)
2.. root the stock
3.. downgrade the modem to MDC ( this i have in a form of one click odin tar )
4.. run the unlock tool and thats it ( that also i have from autoprime)
but i am not able to find the required files which will work on the 4.3

I too am looking for similar info as to if this would work to downgrade my note 2 sch r950 from 4.3 to a lower version that can be flashed or unlocked to work with H20 wireless. They had no problem taking my money and not saying anything about bring your own phone needing to be unlocked. And I'm not even sure if this cdma phone can be unlocked, even though there is note 2's that can be and mine even has sim card slot so lay some truth please

EDIT:
I don't recommend anyone to flash this OTA, in fact I thing I'll shot it down
see post 69 in this same thread http://forum.xda-developers.com/showthread.php?p=57407812
Once again, Don't try it unless You know what are you doing, even when this is a pure unmodified OTA file, it semi-brickd my Moto X
OTA Just right now, android 5.0 lollipop 22.21.17.en.MX Im not in any soak list.
My device is a Moto X XT1097 Pure Edition
I haven't apply it becouse I'm not sure how to root it after the update.
And I'm asking, I'm not in a soak list, so this mean is the official release?
I'm just a user who got the OTA update, so use this at your own risk as I will not be able to help you.

You're on nextel carrier branded ? Can you put this ota on 1097 from carrier ?

It's the same model xt1097, as far as I know the only diference between the stock ROM and the carrier's ROM is the internet settings and stuff. Nextel Doesn't push bloatware or such so I'm guessing they just load some settings and rebrand the sistem version. I'm on 21.27.3, maybe the baseband could bring some problems I don't know... but I'm pretty shure it will work. I've been flashing stuff in carrier models for a while know and besides internet settings I've never had more problems
If somebody knows me wrong please correct me

So, how do we flash this?

I think you only have to check your APN settings. If you have an US model just make shure you're flashing the proper zip for your model. Carriers just add apps and stuff nobody use.
Think of it as installing CyanogenMod, everyone around the world has installed it and yet there aint carrier versions. Everything is about the model, not the carrier.
Anyway, whatever you decide to do you're doing it at your own risk. I'm waiting a couple of days to hear from my carrier so I can't give any help until I do the proces my self.

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 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......

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!

Guessing it depends on your country region .Anyway there is not much diff notice before and after update .

Ppl, does anybody had problems with this phone, now it's a little bit better, something I'm not doing anymore probably, but when I changed predefined apps on my phone I had to restart 2x a day the phone, huge lag and locking.
Had to shut everything to keep it simple...
I really need a CM rom on this... as Stock android as possible.... EMUI is destroying the performance.....

So with all that information that I provided above I am bit confused. I'm not sure if HD Voice is actually working because S8 Dialer doesn't show it. I downloaded a non root Google Dialer APK and it showed HD voice when calling my wife's TMobile number. I would really like to flash this to a completely TMobile version so I can get 4x4 MIMO & 256 QAM features but I am looking at http://updato.com and I see 2 different versions. SM-G950U & SM-G950U1. SM-950U USA TMB G950USQU1AQDE May 1st 2017 or SM-G950U1 USA TMB G950U1UEU1AQE3 June 12th 2017 . At this point I am confused on how I should proceed. If somebody could help me figure out how to proceed I would appreciate it. I have done a lot of flashing and unlocking bootloaders going back to my original Droid X but I really don't want to brick my $800.00 dollar phone right away.
Note: I have read [Snap.] Guide for Flashing Standard FW, Carrier Switching, and Flashing Unlocked FW and I am still a bit lost. Hope this is enough information for someone to send me in the right direction

Might be a TMobile software tweak that enables the NFC icon to show up in the notifications. Might not be enabled in the Unlocked Versions.
BTW What Model # is your wifes phone ..... I can't figure out if I should flash the G950U or the G950U1 ...

Are you sure that US unlocked model on T-Mobile isn't getting "4x4 MIMO & 256 QAM"? In the specs on Samsung website it shows: VHT80 MU-MIMO,1024-QAM, don't know if it is any different.

So with all that information that I provided above I am bit confused. I'm not sure if HD Voice is actually working because S8 Dialer doesn't show it. I downloaded a non root Google Dialer APK and it showed HD voice when calling my wife's TMobile number. I would really like to flash this to a completely TMobile version so I can get 4x4 MIMO & 256 QAM features but I am looking at http://updato.com and I see 2 different versions. SM-G950U & SM-G950U1. SM-950U USA TMB G950USQU1AQDE May 1st 2017 or SM-G950U1 USA TMB G950U1UEU1AQE3 June 12th 2017 . At this point I am confused on how I should proceed. If somebody could help me figure out how to proceed I would appreciate it. I have done a lot of flashing and unlocking bootloaders going back to my original Droid X but I really don't want to brick my $800.00 dollar phone right away.
Note: I have read [Snap.] Guide for Flashing Standard FW, Carrier Switching, and Flashing Unlocked FW and I am still a bit lost. Hope this is enough information for someone to send me in the right direction
Thanks

How to verify that SM-G950U1 do or does not support 4x4 MIMO & 256 QAM on T-Mobile? I might flash my unlocked unit to T-Mobile only if I know for sure that my device doesn't support it.

I'm not sure if it does yet but I would assume so since you are flashing the T-Mobile firmware .. I have tried many different methods of finding out if it does via the device but I think you need root. I tried multiple applications from the play store and used multiple phone codes to open every menu available. I got to the ServiceMode to change bands by using *#2263 / I got to ServiceMode with Debug that gives information about the current Band that you are on and how many MHZ you are running at. It also gives you some additional info: RSRP RSRQ SNR. Unless somebody else has a way to figure this out without root I'm not sure. Also Ill add a list of the current cities with 4x4 MIMO below. I did verify that all HD Voice, Wifi Calling, Video Calls, & Volte work .... Verified by downloading Shortcut Master Lite https://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite&hl=en ( Under App Explorer / System Apps / IME Settings / ImsSettingsLauncherActivity / Launch ). I am happy with the TMobile Version .. It has T-Mobile App installed and Lookout but there is ways to disable those and remove them without root. I haven't removed them but i read it is possible ... Doesn't use much RAM. If you need anything else let me know!

So from your 1st link, I do see that my city is there (WA), but second link, didn't have it.
I have done flashing via Odin many times on my previous Galaxy phones, so I feel comfortable, but I am kind of debating...if I really need to flash and if I will benefit from this.
I will ask you few questions and it may help me make a decision:
1) Have you measured download speed using Speed Test before flashing T-Mobile firmware? If yes, any difference?
2) I hear that my phone calls are clear and pretty positive that HD Voice is there, even though there is no icon.
3) VoLTE, Band 12 and WiFi Calling are supported and work well. Never had a reception issue or call drops, at least not yet.
4) As for RCS support, do you see it often when you text other users?
5) Video calling - your phone should have it, have you used it?
6) How is battery life compared to an unlocked software that you had before?
From the list above, I would flash to T-Mobile if: #1, 4 and 6 are working properly to make user experience better. I do know that RCS even on T-Mobile is limited to phones that support it, for example Glalaxy S6, 7 and 8 and possibly Note 5. Also some LG phones I believe had it as well.
In other words, what did you gain when you went for T-Mobile firmware?
Before I forget, you used Odin and added needed files such as BL, AP, CSC(you probably didn't you HOME file, just CSC) and also USERDATA TMB file - I am correct?

Any updates on whether or not the Unlocked USA S8 supports 4x4 MIMO & 256 QAM on T-Mobile? I've flashed the T-Mobile firmware on my unlocked phone and haven't noticed any speed decreases or increases. Any new way to verify that s 4x4 MIMO & 256 QAM is actually active with the unlocked firmware? I believe it is doing 3x CA though...

I am trying to find that info for sometime... I have seen somewhere that there is/was an app in play store which was similar to LTE Discovery, but it did show more info on 4x or QAM, I don't really remember. That time I didn't need this info, so I didn't really pay attention. I found this site that has some info: http://www.howardforums.com/showthread.php/1888849-How-to-tell-if-using-4x4-mimo
