G955U is using G9550 model version - Samsung Galaxy S8+ Questions & Answers

Hi respected members, I'm new here and I need your valuable assistance .
I bought S8+ and when I checked the model version in software it is showing SM-G9550 which is Chinese version not Hong Kong, but on the back of phone G955U is mentioned. For more confirmation I compared the IMEI and serial number which are mentioned on the back of phone and also showing in software information in about phone. IMEI and SN are same in about phone and on back side of phone. I also checked the carrier in downloading mode (after pressing Volume down + Bixby + Power Buttons) and carrier is VZW which is Verizon if I'm not wrong.
I'm foreigner in China and current Chinese version is creating problem in phone that no any update (current is 7.0) for my S8+ software and the latest security patch is 2017, some APPs like Facebook and Whatsapp don't show any notification etc.
I already used Hong Kong firmware in my GalaxyS7 Edge which works perfect and also have Google APPs, but Chinese version don't have Google APPs, and there is no any play store library. To solve this problem, I tried to install Hong Kong based firmware (9.0) but Odin shows error that can't create partition, after reading about this problem it seems that firmware is not compatible with current hardware.
So I want to ask these questions!
1: How I can install Hong Kong firmware in current situation or if I install G955U then will it work in China? and from where I can get unlocked firmware because I'm unable to find unlocked firmware. Reference (https://firmwarex.net/samsung-s8-sm-g955u-9-0-official-firmware/), from this link which will work in my phone?
2: If I used PIT file to install Hong Kong version then is there any security problem or my phone will work well?
3: I'm unable to find PIT file for my current problem. I also need PIT file if first option will not work.
Sorry for too long explanation.
Need your kind suggestions. Thanking you in anticipation.
My problem is seems to be same as https://forum.xda-developers.com/galaxy-s8+/help/g955u-using-g9550-firmware-t3766862

Problem solved
I have solved my problem. As mentioned in my question G955U model is using G9550 because processor is same but RAM and storage is different.
I downloaded G955U1 from SamFirm and installed it. Working fine now.
I used this phone in China and Pakistan. The main problem in G9550 I was facing, it was 4G signals strength that were very weak in China and 3G was not working but in Pakistan 3G was working fine but no 4G signal on same phone. May be that was due to different bands. But now after installing G955U1 the LTE signal strength is very strong even better than iPhone X.
Still I'm searching about it that how anyone installed G9550 in G955U as I also tried latest G9550 on same phone but I was failed.

These guys will cross match the csc files to include carrier features for other country's. You can't out right install the 9550 firmware but can add bits of the csc to it. I've seen a bunch of "mutt" frankensteined devices. But don't like to get involved because stuff can go wrong real quick

Agree with you. I want to add bit more that G955U is 4GB RAM and 64GB Storage but G9550 is 6GB and 128GB. Obliviously firmware check the right configuration. As per my knowledge that we need to provide right BL (Boot loader) file. I mean BL file from G955U but other files from G9550. May be I'm wrong because I didn't try for it. This combination will work?

i have a similar problem too. i have a sm-g995u, i know because it is written on the back of the phone and also in the software info menu. however when i get into the AP and CSC values it says my phone is sm-9550. im currently suffering from poor network and i've currently lost signal. i mean my phone has been displaying "no service" for the past 2 days. I'm currently considering flashing another firmware but scared not to brick my device since i am a newbie with all this stuff.
my device is originally a g995u, if i flash a g995u1 firmware would it work?
what g995u1 firmware did you flash? i need help asap, ive been offline for a while because of "no signal" problem.

Yes you can install G995U1 in your phone. In my case I was also facing poor network issue, no phone call history and no live location for maps but after installing the G955U1, everything is working fine.

thanks man. i was able to flash the G995u1 firmware. However, my problem still remains, i still have no access to network. i cant seem to toggle or change network mode. its stuck on LTE/3G/2G, i suspect when i was on the road the connection to the lte was lost and failed to switch to the 3G. i see alot of people have similar issues.
i sincerely hope it is not a hardware issue like a roasted network chip...
sorry i cant use wechat because i have formated my phone. Kindly recommend any possible solutions please.

It seems that there is problem with your network chip but yeah you should make sure that your phone hardware is based on G955U. G955U (USA version) and G9550 (Chinese or HongKong version) have same processor. As I already told you that my phone hardware was G955U (Verizon version) but G9550 firmware was installed because I bought it from China. I was facing many problems like slow speed, no live tracking of location using any navigation app, no call history and poor network coverage. After checking the phone I came to know that originally phone is G955U, you should also double check your phone version especially in downloading mode. After all I installed G955U1 (unlocked version) then everything works well. If your problem is same then G955U1 should work well. I installed Android 9 version.
Furthermore if you will try to install other versions like F (Global version) then obviously you will face other problems too.

Possible to convert flash SM-G930U firmware on a SM-930P?

Hey guys!
Yesterday I got a Sprint carried S7 SM-930P as a gift. The only problem is that although it works flawlessly on my sim cards (I'm not in the US), I found out that the 930P won't get the 7.0 update. Is it possible to flash the G930U firmware without messing my phone up?

I wouldn't do it unless your absolutely sure, I wouldn't be so sure if it's for a different model number. If they were able to have the same firmware flashed Samsung would just release it, they obviously didn't because it requires extra effort, pointing towards the conclusion that the firmware is not flashable on 930P

You can flash it, i have done it myself. There are many guides over here that tell you how. All S7s in the USA are the same exact thing hardware wise, only the software (firmware) is different. Am currently running SM-G930U firmware on an SM-G930VL S7. @op the sprint s7 (SM-G930P) already has android 7 as of last 3 weeks

SM-G930P converted to SM-G930U
Hey guys. I was able to flash the sm-g930u firmware downloaded from sammobile... the problem I have now.. I have a blank csc. No product code.. and on software updates it fails to register my device. Also in settings . I have some weird options. Which some of them are repeated. I will upload screenshots.. Also there's a system UPDATE option and also software option. Which one of them fails to register and the other only works with Wi-Fi. Should I revert back to my stock sprint firmware. If so do I need to wait for a firmware with same build date or newer. Because on sammobile haven't uploaded a firmware with a build date on par with the current install. Then I would have to wait right. ? If using a older firmware it will brick or do something to my phone ?​

Did you flash all file in the SM-G930U folder (AP,BL,CSC,CP)? Because i did it with T-mobile,Verzion an it work fine
Thanks for the reply. Already solve.. what happen i flash home_csc. So ir was like that. But then i made a back up.. and flash again using the csc file. And all work perfect. At first phone was with the SPT csc.. then after i restored phone and pop in my sim it did something.. and now I'm with XAA csc. Works perfect. And could receive updates (phone registered). Just waiting for the july security patch update. Btw phone works better in every way.. battery even last longer..

Hey Buddy. I would recommend doing a full back up on your phone., using Smart Switch app
It saves all your numbers, message, etc..
Then proceed to flash the latest firmware for the Region or Provider. Using (CSC) not (home_csc) which means flashing the csc will wipe your phone data. Phone will be like new again. Proceed tru set up. Loggin in gmail. Proceed to update smart switch app if not found in apps. Then restore from the back up file. And good to go.

actually all S7 are not the same hardware fyi. The Sm-g930p has chipsets snapdragon and uses cpu procesaor quad core but the sm-g930F has the chipset Exynos8 cpu is octa-CORE the chipsets vary from these two. Flashing firmware for one chipset to the other may cause major problems bot to mention bootloops.. but I looked up sm-g930U and it uses the same processor as the P model.snapdragon

He said all S7's in the USA are the same, which is correct. Exynos/930F isn't sold in the US, only way to get one is to grey import.
You can flash any USA model's firmware onto any other USA model because they're all the same hardware.
anyone running the 930p with current update how did you get around the binary 6 lock all the 930U firmware versions I can find are binary 4 I think t-mobile is 5. Anyone got links to a firmware we can push to sprint variants that are binary 6.

You can't get around it. It is currently impossible to "downgrade" the bootloader binary version. All US carrier variants are version 4, except Sprint that is 6. You are stuck.
The only way it would ever be possible is if (a) one of the carriers, in a future software update, increases their bootloader version to 6, or (b) if someone figures out how to unlock the bootloader for the Snapdragon models.
Neither of those options is likely to happen, ever. You might get lucky and hope the G930U unlocked version has a higher number (it hasn't been released for Oreo yet), but I wouldn't bet on it.

Blame Sprint; there is really no reason for them to do what they did except keep users from switching their phone to another carrier. This isn't a Samsung thing. I don't believe you would be able to do this with any other Android phone, either (i.e. go backwards in bootloader versions).

Galaxy s7 "updates software" option missing

Hi, I have just bought a brand new galaxy S7, model SM-G930F.
Although it is an international model, it carries a snapdragon 820 processor.
I am told , that it is a USA model, built under Verizon.
SM-G930F is supposed to be a global model with exynos, does anyone knoes what is the phone I bought?
Anyway, my real problem is, that the "updates software" option is missing, in "about phone" list.
I am stuck in android 6.0.1
I checked it is not rooted and it must be a genuine phone.
Can anybody guide me through solutions?
I would really appreciate any help.
Thank you
Moving to general S7 Q&A since you say it's a SM-G930F.
Check the back of the phone and verify the phone model. You should be able to update through other options like Kies, unless they've changed that recently.

It's not a G930F if it has a Snapdragon processor
Commonly faked to look like G930F by editing firmware / stickers / model numbers etc, more likely to be the G930V if it's Verizon
Boot to download mode and check the model number in there, that's the only one that can not be faked
(Volume Down & Home & power)
And they likely removed the update option from settings to prevent any problems of the phone updating to either the wrong firmware, or removing their fake edits with a V update
Flash the proper firmware with ODIN 3.12.3 or newer from updato.com once you know your model S7
Galaxy s7 "updates software" option missing
Dear Durham,
Thanks for the help.
Yes, you are right; it is G930V.I have been tricked...
I have visited updato.com and found 12 variants of S7 firmware.
My bootlader version is - 6.0.1 November 20, 16 USA (Verizon) (VZW) G930VVRU4API3
Shall I download and install this one and afterwards make a manual software update or
shall I install the latest - 7.0 August 25, 17 USA (Verizon) (VZW) G930VVRS4BQH1 ?
After successful installation, will these firmware fake modifications( to G930F) disappear permanently?
I am much obliged
Thanks

The ROMs from updato.com are full ROMs so you can just flash the latest / newest one and you'll be 100% up to date once it boots
Use CSC and not HOME_CSC though as you are going to want to reset after the flash to clear any hacks from the previous ROM (This will wipe the device so backup any important files first)
CSC, AP, BL and CP
Yes this will permanently remove any modifications from the faked ROM
Wish me luck, I will give it a go!
You have been most informative, many thanks.
Good luck :good:

The good news is that the verizon edition can be rooted and is network unlocked from the factory so as long as ure carrier supports the bands it will still work for you on a side note flash the u firmware not verizon and u wont have any verizon bloatware out of the gate either
Mad scientist, thank you for your intervention.
Just to be clear, which firmware do you suggest me to install, not the verizon G930V?
Could I install the G930F for my country (Europe).
I thought they are incompatible...
As my bootloader version G930V I think I would better stick with the V version.
Are you suggesting not to upgrade to nougat and reinstall factory installed 6.0.1 and better wait for 8?
Yes you are right, I am not good at twiking.Will I have drain baterry issues with nougat?
Dear Durham,
Emergency help!!!!
I installed it succesfully but now it does not recognize my sim card, as it is from a non USA country.
Should I reflash a different firmware? F or U ?
I am from Greece
It seems to be working...
The Verizon logo appears upon starting the phone
But in language selection, there is only English and asian languages available.
Software update finally appeared.
In order to have my langage back, should I reflash with the U ( unlocked version) or the F (global)?
No mobile data.
Maybe I am calling through Verizon.Roaming.Expensive.Scarry...!!
He means that the G930U firmware will flash fine on the G930V, it is the same firmware but without the Verizon bloatware added
You can not flash any other firmwares, it just happens that those two are compatible with each other
Flash straight to the latest
So I shall flash the G930U?
Will my sim card be recognized and mobile data be active.
Nougat 7 or MM 6-your opinion, again?
thnks
No idea if your SIM will be recognised, but if it's not working with the V firmware it's worth a try
As I said, flash the latest firmware which is Nougat
Personally I would be contacting the seller and asking for a refund / exchange for a real G930F that you paid for
firmware
I tried, but he is not cooperative.
How about F version-it worked with it before ?
(only it was modified with the dissapearance of system update.)

No you cannot flash any other model firmware, that was NOT the G930F firmware, it was a hacked / faked U or V firmware
I think you better read a good few threads before going much further or you're going to end up with a brick
Contact the seller and request a refund
Don't suppose you can flash CSC files of the 930F on 930V?
Dear all,
Thank you for your help and interest in my problem.
This is indeed a great forum!!!
I tried to flash the F version, but thankfully odin stopped it from the beginning, presenting "failed" message.
I suppose if it continued, I would end up with a brick as Durham suggested.
Finally I flashed he U version, as mad scientist suggested, and up to now it works like a charm.
As Durham advised, I used CSC and not HOME_CSC and the hack was eliminated.
Sim card is recognized, no bloatware and mobile data working.
Let's hope it will continue like this...!!!
Only glitch, not everything is in my home language ( message icon name and in settings-the menu options-any idea how to fix it? - I removed english and left only my language as selection, but onle these remain untranslated)-small problem
I have learned a valuble lesson from my adventure.
Ebay, an organized platfrom may it be, it cannot control each individual's deceivals, so one must be extra wary when buyng from unofficial sources, nomatter good reviews from others...
Thanks again to you all for your help, I would be in serious position right now, if it weren't for you guys.

Samsung SM-G930S... all the same as

I have a Samsung SM-G930S... which is Exynos 8890.
Can I then put on any ROM from any other Exynos 8890 based phone? And all will be well?
All will be well if you enjoy a brick
Only flash stock ROMs for your model S7 (G930S)
Bootloaders etc are different between models, it doesn't just depend on the chipset

012512, thank you for your answer. I will look up those two ROMS. This rooting of the Samsung phones seems a bit more complicated than the last time I was rooting, the LG-G3 and the OnePlus One, or is it my imagination.... or just getting more-forgetful?
When you look for ROM's compatible for your phone, are you looking specifically that they are for the SM-G930S, or exactly what are you looking for? Other non-Korean variants that will work?
Thanks again.

Any custom tw roms will be fine. Take note that aosp roms are no longer supported for korean variants.
S7 korean variants are g93xK/L/S
So if you install a g930/5F custom tw rom, you can install it on your phone as long as you don't install the stock g93xF/FD roms.
Also, there is a separate twrp for korean variants in order to install a custom tw roms. Please refer "heroltekor" twrp.

Excellent information, thank you. By trial and error, before picking up your post, I put on an Exynos Infinity 8+ from v8. It seemed to flash fine using the default Bixby CSC indicated in the setup. I did this last night so have not had time to chck out all things, however, cell phone, messaging, bluetooth all work just fine. I'm about to clean install the v17 of the Infinity in a few minutes. TWRP is a a** saver and my friend.
Thank you, again.

Hi,
I bought Samsung Galaxy S7 SM-G930S from the store which was converted into SM-G930FD as I was not having Korean sick apps installed in my mobile and there was no Korean logo of "BANDLTE" while switching off and switching on, when I saw my phone model name it was SM-G930FD and was supporting dual sim both had a same IMEI. But when I restarted my mobile after getting home phone got locked with this message "Custom Binary Blocked By FRP Lock" so decided to got into boot menu there I saw SMG930S written so i flashed mobile with SKT Korean firmware of smg930s but when I installed it I got tons of Korean apps and getting "BANDLTE" logo while switching off and on my phone I lost that Samsung Original logo which I had when my phone was converted into smg930fd. Now I want to switch back to Smg930fd settings/firmware so get rid of these Korean apps and Model to be appear as SMG930FD as the back of my Samsung Galaxy s7 glass has a phone model SMG930FD. I don't know Shopkeeper scammed me or what I told him I wanted to buy SMG930FD but he gave me this converted phone Kindly help me to get back to SMG930FD firmware/settings

Same case for me, one thing different is that i bought the phone used from some random guy on the internet, i tried OTA to get Oreo as the phone had Nougat but it says no update available for me, 4G didn't work on my netword too, then when i saw samsung health not working i thought knox probably is voided when i checked odin i found its a 930S instead of the FD.
I do believe there is ways to convert to the 930F/FD by flashing select flash, using a box/dongle or some paid tool like R3 or Chimera or whatever you can get your hands on. I work on a repair workshop, have those i mentioned above and i saw this feature where you can actually select which part you wanna flash from a specified md5 file, i didn't test it on any phone yet, but i think they flash the bootloader of the real variant 930X but they put the AP of the international version 930F/FD, from the AP file you can also select what to flash and what to not, so you can actually only flash system.img of the XXXF version and the rest can be from the original variant. Never tested it but i think that's how it works.
My advice is to return the phone, that's what i'm going to do as i just bought it today (i was a happy dumbea** already bought few cases and whatnot...) the phone is still good and all functions perfectly, 4G might not work on some networks due to the different bands but everything else is the same! there is a big chance you can get the international firmware on it and be happy with it, but there is always a chance of breaking it too! or getting a network lock which i guarantee you, you're not going to like...
I don't know if this type of phones is refurbished, but i really hate that Samsung actually does that or allow this to be possible (happened before with an S6), same goes for LG too (Had a v10 korean model with Tmobile firmware).
Again, my advice, return it!!
Okay so here is an update on my case, might help anyone. if you did read my previous reply you'll know that i bought the phone from someone online, contacted him back he didn't block me nor ignore me, he even called me himself, but he bought a ps4 with my money and can't go back. Still waiting to see if he can get the money back, but what i was thinking is to ask for few dollars back just cause 4g network and dual sim functionality doesn't work on the phone, again its a 930S with 930FD firmware, after confirming and playing around its actually 930F not FD so i think i can get back the dual sim function. I'll be flashing the phone if i got no money back, try to get FD or 4G working on it and sell it for maximum price, then use the extra money i'll take from him to sorta re-gain my money and try to find a better one.
If i ended up flashing this 930S to a 930F or FD i'll post the method and the result and link it in another reply for anyone interested.
Wish me luck.

Bro I found a way you can download custom rom of smg930fd by installing TWRP or CF auto root method in this way your model will I guess automatically turn into dual sim supported and model will be shown as smg930fd.

Hi,
I'm facing the same situation. I bought G930FD dual sim but later I found that it's actually G930S.
Now I want to install its stock firmware which is Android 8.0 by SK Telecom, Korea
Can you please tell me:
1. Changing the ROM will covert the phone into Single SIM version?
2. The phone will lock to Korean network only?
3. This will change everything into Korean?
Cheers

1. Yes it will!
2. This one depends if your phone is unlocked or not, most of the time it is unlocked.
3. The firmware is all the same Korean, US, Canada or international the biggest difference will be in bloatwares, as I had that phone before I can tell you, you'll have many SK telecom apps.
4. (this one I added) If you flash your phone with the original Korean firmware which is by downloading the firmware for the S7 SM-G930s from Sammobile and flashing it using ODIN, going back is quite hard! So if you're network locked or you want the dual sim functionality back, you'll need a special tool/dungle called Z3x to make the thing work!
5. (I also added this) To unlock the phone and make it work on all networks there is a process called "Patching the certificate" and it requires an unlocked bootloader which probably you already have, and root! and most importantly! it only works on Android Nougat. Basically what Im saying you can only have dual sim function in Android Nougat with the 930FD firmware, also if you flash the original firmware and its network locked, if you wanna go back you'll need that tool I mentioned and again, only Android Nougat.
Had that phone before, still have the firmware backup for the 930StoFD also. I can help if needed.

Now I'm confused to select a blue pill or red one
At one hand the current OS is outdated and have a very annoying and UN-stopable adware buit-in; but it's dual SIM
and on the other hand I may have an updated and ad-free OS by sacrificing dual SIM functionality

What you can do is install TWRP recovery, you can download it from "twrp.me/Devices" and look for your specific device, backup everything and transfer it to a PC or a memory card, just in case you'd like to go back later, then you can flash the original firmware with Android Oreo and see if you like it more and if its worth dropping the dual sim for! if you don't like it, you just reFlash TWRP as it will be erased, format the partitions and restore the backup, You'll be back with Nougat and dual sim function but the network won't work till you patch the certificate (used to be called repair network), and for that you'll need root, debug enabled, and the z3x. Your issue will probably be that last one, z3x, cause as far as I know you'll need this tool or a similar one to get the network to work again! and just to mention, for some reason, if you erase the dalvik cache or reset the phone, you'll have to patch the certificate again.
Just think it through carefully, I work in a repair shop so I got access to lots of tools, but in your case if you don't, it might be quite hard to get things working again if they break.

Happy to hear the issue is solved.
Couple of things you can try for a better experience if you like modding and tweaking.
If you have root and magisk, you can install a module that enhance your camera, it will increase the quality and add some extra features (I just installed it three days ago on my S8+, and the S7 is also supported, love it)
You can install a sound mod that gives you stereo like sound by using the earpeace and the bottom speak together.
Also with root you can patch your host file (Luckypatcher can do that) to block like 99% of the ads within the apps (I can't live without this one, life saver)
And can find tons more withing the forums, these are the ones I tried myself.

Canadian s7 not recognizing getting network with a european sim card.

So I've bought a second hand galaxy s7. It is a Canadian model SM-G930W8 . I live in Greece and have to use a greek sim card , the phone recognizes the sim card , but in the info it says unknown. Prior to an update I made it worked fine , but after the software update I am unable to get network reception . Anybody happens to know a way to fix the problem ? Will flashing a greek firmware solve the issue ?
You can try flashing just the home_csc, which contains carrier and frequency settings, from the Greek firmware onto your G930W8, but I'm not sure how different the 930W8 is to the 930F so you might risk a bootloop and have to flash stock. So make sure you've got what you want backed up.
What was the source of the update? Phone shows the correct IMEI?
I believe the 930w8 is exclusive to Canada.

Somehow the update messed it up? Is it a stock update from Canada? I have a Canadian s7 from bell on 7.0
I updated the phone from samsung smart switch , the phone was probably modded beforehand to run greek sim cards, and the seller never mentioned this.And with the update the mod was most likely wiped or something.

Try a different stock from sammobile or a Greek rom. But there shouldn't be that issue. Mine works in London with no problems.
I asked about the imei to ensure that the phone is showing the correct imei.
The model number has been confirmed in download mode?
Yeah I went in download mode and it is the one I have stated above , same model number on the back of the phone , I will check the imei when I get a hold of the phone , because a friend has it right now. Will try to flash greek firmware. And report back.
I booted into recovery and what is said there
-- applying multi-csc...
Applied the csc-code : TLS
successfuly applied multi-csc
That means that the phone is using the Canadian Telus Home.csc (I guess) .
So would flashing the home.csc from the Greek firmware work ? Does it have a chance to hard brick the phone ?

At&t branded phones on Tmobile network

My wife works in a hospital and we used wifi calling because reception was poor.
It's still poor with Tmobile but no wifi calling. When we moved from At&t the wifi
option was greyed out. Tmobile states that it works fine on their network.
Is there any way to get a samsung s7 g930a and a samsung j7-j727a to use wifi calling
on the Tmobile network?
I'm sure it will probably involve something over my pay grade but I am willing to try
anything needed to get this feature to work

If your current firmware has WiFi calling (Volte) You can only use Volte if the network supports it. There are however many apps you can use for WiFi calling look on the play store.
Not sure what volte is, I have had some other issues with the
service that I thought might be resolved by installing a
different rom
Tell me if i'm wrong
Thanks

Volte is wi fi calling over a network which the network operator supports without the need for a specific app.
Please tell me exactly what you are trying to do
What network are both phones using?
Which networks were the phones on initially?
Have you modified the phones in any way? Root? or TWRP?
What firmware are both phones currently using? Go to Settings>about phone>software information>baseband version G930A????
Sorry for not getting back sooner
Both phones are currently on Tmobile network
Both phones were originally on At&t network
No modification
Samsung s7 g930a baseband version G930AUCS8CRL1
Samsung j7-j727a baseband version J727AUCS4BRL1
Note: Wifi calling was available on original at&t network but is now greyed out on tmobile network

Ok since wi fi calling is network specific (some have it some don't) you either need to have unbranded firmware on your phone so it works no matter which network is providing it, or you need to now flash T Mobile firmware for it to work again on your phone.
US networks are a nightmare when it comes to this sort of thing and it's a right pain in the a** to solve it. So what you need to search for now on here is how to flash different firmware on AT&T S7. You should always try to flash unbranded firmware so everything works easily, if not it will have to be T Mobile Oreo.

Ok since wi fi calling is network specific (some have it some don't) you either need to have unbranded firmware on your phone so it works no matter which network is providing it, or you need to now flash T Mobile firmware for it to work again on your phone.
US networks are a nightmare when it comes to this sort of thing and it's a right pain in the a** to solve it. So what you need to search for now on here is how to flash different firmware on AT&T S7. You should always try to flash unbranded firmware so everything works easily, if not it will have to be T Mobile Oreo.

Ok, If you think unbranded is the best way to go can you point me in the right direction
updato.com and sammobile.com both host firmware and have flash guides. SamFirmTool also is good for downloading firmware, but only lets you download the latest version and isn't as user friendly.
For unbranded you'll want to look for G930U firmware.
For best compatibility you flash all 4 files using (AP,BL,CP,CSC) this will wipe the phone clean. Otherwise you can try Home_CSC instead of CSC (So AP, BL, CP, Home_CSC) , which keeps your data but may not fully resolve your issues.

What beanvee has said but I think it's worth mentioning I find Sam Firm tool pretty straight forward to use and you'll always get the firmware in separate parts which can be useful.
I found a link for the G930A here
I'm not really understanding the differences in firmware. How is flashing with this firmware
any different than what's on the phone right now?
I am just trying to get the wifi calling to work, How is flashing it with at&t version firmware going
to help me on the tmobile network.
I guess I don't know what I need, stock, unbranded, official or custom rom.
I checked all sites listed and there is no firmware for the J727a, alternative?
I would rather someone more knowledgeable guess what I need to do, if that is what is
necessary because the phones are no good to me without that feature. Any suggestions
would be appreciated.
Each carrier deploys their own CSC file, which contains carrier specific configurations, and its this file that determines if VoLTE or VoWIFI is enabled and how it connects.
AT&T may have different VoWIFI settings to TMobile, which is why using AT&T firmware it doesn't work. Some carriers outright disable it since they don't offer it.
Your best bet would be G930T firmware https://updato.com/firmware-archive-select-model?q=SM-G930T&rpp=15&order=date&dir=desc&exact=1
However unbranded G930U should also work because the unbranded firmware is meant to work on all cariers. G930A would likely get you no where since it'll be AT&T specific
The phones in the USA are all identical hardware under the hood, the only difference is the carrier branding and firmware.
But that's only for the S7, I'm not familiar with the J7.
And it's not through lack of knowledge @JohnAtlas, US phones are a nightmare to do anything with. There are several options available but it's difficult to explain what to do and how to do if you are not familiar with how the software works.
There are many guides on how to unlock the software on all US networks, and depending on the network can include multiple steps to complete, you just have to search and read.
Ok, I was able to find the latest firmware for the G930 phone
I installed odin and have the files, BL, AP, CP, and CSC or Home CSC
My question is, Do I load all files and then start or do one file at a time in odin
I tried all files the first time and got failed error and dismatch
Thanks

All files in correct slots and use this Odin https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Put all files in and used patched odin via link
Received fail and screen that said, "An error has occurred while updating the device software"
After reading more, tried to install twrp and received secure check fail : recovery
Rebooted phone and this is the screen right now, not sure what to do next
Thanks

That is the system recovery and when you flash with Odin you need to put your phone in download mode first press volume down+home+power. The phone should not go to that screen you have posted either before or after Odin, its a completely different recovery mode.
Get your firmware from updato. Com or sammobile
G930U, filter by USA and choose the latest XAA or USC and use the modified version of Odin. We know this works because thousands of people have used it to do what you are trying to do.
Thanks for info, I used G930U TMK version since we are on Tmobile carrier
It seems to be working fine and wifi calling is available
There is no TMK version for the J727U but will try the XAA for the other phone
The way I understand it is that the U means unlocked and the XAA is generic and not carrier specific
Please advise if I'm not on the right track
Thanks for your help

That's brilliant , glad your up and running.
So the letter "U"after the "G930" denotes the region of the world the device is build to operate in, the Americas just happens to be U. The unbranded firmware is the one that has a region but no network assigned to it, so a 3 letter code is used instead, in your case its USC, or XAA.
Europe is G930"F" or "FD" and the 3 letter code for unbranded is BTU & XEA.
Anyway if your phone is running great on T Mobile then don't update it anymore, turn auto update off. The advantage of keeping it T Mobile is you have the wifi calling, the unbranded firmware needs more fiddling around with the get the wifi calling working on the network your using, so best to stick with what works.
I will have a look for firmware for the J7 you have to see if i can recommend doing something with it to get the wifi calling working.
*update*
So it seems the J727 is the same as the J7 in terms of the internal components, everything is the same in both models so that's great news. I think the "27" bit is just a marketing thing.
In theory you should be able to flash the latest T Mobile Oreo to your device from this link https://www.sammobile.com/firmwares/galaxy-j7-pop/SM-J727T/TMB/download/J727TUVS4BRK1/249137/
Now before we start please check / do the following to avoid further problems.
1. Save everything you need from the phone to your pc.
2. Check that you have OEM unlocked in "developer settings" and "USB debug" enabled.
3. developer setting menu is, settings>about phone>software and information>build number>tap 7 or 8 times, developer menu should now appear. (Sometimes it's somewhere else but build number is what you want to find and tap on 7-8 times).
4. To avoid any issues with device FRP lock, delete your google account off the phone., settings>accounts>google. delete it. When successfully flashed you just add the account again when the phone starts for the first time by signing in.
5. Use the same version of Odin you used to flash your S7.
you can also use updato.com (i think it's slightly faster than sammobile.)
Let me know how you get on.
Remember J727T (TMB) is the firmware you want.
