Hi All, I want to continue using my AT&T prepaid plan but I recently bought a locked T-Mobile Galaxy S7 SM-G930T (I'm going to try to unlock it - if that doesn't work this is all moot). I would like to flash AT&T firmware so I can use the AT&T LTE bands. Can I follow the instructions in the link below once I've unlocked a T-Mobile SM-G930T and turn it into a SM-G930A?
http://www.droidviews.com/nougat-firmware-on-att-galaxy-s7s7-edge-sm-g930a-g935a/
I've read the link below... but it seems to be only if you want to continue using T-Mobile service which I don't.
https://forum.xda-developers.com/tm...w-to-flash-att-nougat-to-t-mobile-s7-t3553610
Changing firmware doesn't have anything to do with what bands the hardware supports. Unlock it and throw the ATT SIM in. Only difference is carrier supported features and software (wifi calling, etc). Flashing ATT modem might improve coverage but all S7 support the same bands.
Thanks buddy for the reply. I'm used to using a custom ROM on my Android phones so this is new. Mostly CyanogenMod.
That's good to know I don't need to flash in order to get the bands but I understand I need to if I want OTA updates from at&t. It seems relatively simple that you just flash the AT&T ROM over the T-Mobile with Odin and then use some update file. It doesn't even effect Samsung pay and Knox which is great.
Stupid question: is the AT&T modem included with the AT&T rom? Also, with regards to the 2nd link in the OP what is the update file that you put on the sdcard to use in recovery - is that an OTA update because your ROM is different from your carrier?

The following is the latest G930A Android 7.0 firmware file. All you need to do is flash it with Odin's AP slot to completely convert your G930T to a G930A. No other steps or files are required: G930AUCS4BQC2_CL10280464_QB12904132_REV02_user_low_ship_MULTI_CERT_meta.tar.rar

I don't get why you would do this other than to have ATT bloat over TMO bloat (IMHO TMO has less bloat than ATT). There's no technical advantage. Am I missing something?

The amount of bloatware is irrelevant since you can freeze all bloatware on either build. I experienced many issues on the TMo version including issues with Android Auto, Google Assistant, and Tasker. I thought these apps were buggy but all of those issues were resolved on the AT&T version. The AT&T version seems to be a better, bug-free build.

Read that in a different thread you posted to after I responded. I think it's very YMMV though. But if you saw improvement then ??
Hi, did anyone ever complete this flash from SM-G930T to SM-G930A? I'd like to do this solely to try and get the wifi calling feature since my workplace has poor cell service but great wifi. I bought the T-Mobile phone, unlocked it, put the ATT sim in and everything but wifi calling works fine. I appreciate the reply!
This is much later in the year (11-8-2021) and ATT has posted the list of phone they say will work and it only shows G930A. It seems their test of working means it must have been sold by ATT. They say My G930T won't work. So Will ATT continue to use customer's unlocked phones it they were not orginally sold by ATT. They have the records. Will ATT refuse to use one of their SIMs even if the phone is Flashed to ATT logo. I do not want to throw away my G930T phone.

Hello and thank you. You posted this information and link back in 2017 and so much has changed. Mostly ATT is now working hard to get rid of all 3G towers and firing up 5G. They said my Galaxy S7-GM930T would not work so I think they link you posted will help me convert the phone back to a GM930A or U or U1. My question is,..Has anything in your post changed since 2017 and if so could you please advise me of what I need to do. Thanks very much.

They sent you a message saying the phone won't work?
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.
Hi all
I just purchased the International S8+ dual Sim variant, the G955FD, from eBay.
I live in Canada and will be using both a Telus Sim and a Rogers Sim.
Is there anything I need to worry about regarding the CSC type?
I found this thread, https://forum.xda-developers.com/ga...ility-flashable-csc-selection-v1-0-0-t3605264
So it seems easy enough - I just don't know if and when I need to change the type.
And should I even be changing it to Telus or Rogers, since they don't have this variant?
And yes this is my first Samsung phone
And input is appreciated!
Edit: if it matters, I don't use wifi calling for either Telus or Rogers. I also plan on simply rooting the phone with magisk to make some mods, and put on Android pay
Just curious. Where was your Duos sourced from?

Great question.
As I did more reading on the device I checked the eBay listing and didn't see exactly where it's sourced from. I should have it in hand by Wednesday and I'll try to validate then. What should I be looking for?
Is there a specific source country that works better than others?

Firstly, congratulations on the new phone. I've got a 955FD as well.
It doesn't matter where the phone is sourced from, although if you want to check, you can go in to settings > about > software information > service provider information and see the CSCs listed there, in this format 'XXX/XXX/XXX'
The first one is the active CSC on the device at the time of you checking, the second one is the CSC for the SIM card currently being used, and the third CSC which can not be changed at ALL is the one from which country the device was sourced.
I'm in Pakistan so for me the CSC format is: PAK/PAK/MID
First two are PAK because that's the CSC for my SIM card and because it's the active CSC on my device, however the last one always remains as MID since that's where my device was imported from.
Canada has no CSCs available for the G955FD sicne it's the Exynos variant and the one sold in Canda is the G955W which is Single SIM and SD835, however the CSCs should work regardless of device variant. You can flash the CSC for whichever is your main SIM card, or whichever you use more often. Either Telus or Rogers, entirely up to you.
The benefits of flashing your carriers CSC is getting stuff like VoLTE and WiFi calling (and sometimes even 4G+/LTE+) to work. No harm in doing it since you're going to root anyway, so make sure to flash whichever one you prefer.
Magisk, rooting, mods, that's all fine, but do confirm properly about Android Pay before actually going ahead and rooting.
Samsung Pay will not work in Canada with the 955FD, and will definitely not work anywhere at all once you've rooted and tripped the KNOX warranty counter. Android Pay can be tricked into working by passing SafetyNet with Magisk, not sure if this still works or not though.
Other than that you should't have any issues.
If you've got any more questions, just tag me or quote this post and I'll be happy to help.

Thank you!
The break down is very much appreciated.
Is there any issue with flashing (via TWRP or Odin?) random CSCs?
Since there is no G955FD in Canada, I don't want to break anything.
I'm very comfortable with flashing and modding the heck out of Android phones, but Samsung seems to be a totally different ball game lol
I obtained a Galaxy S8+ G955FD Dual Sim from e-Bay as well, sourced from UAE. I was able to register US issued MasterCard and Visa on Samsung Pay.
I am on T-Mobile, other than not having WIFI calling, the G955FD works great. Rooting the phone would most likely break the Samsung Pay. So that is a decision you need to make.

No issues at all. Plenty of people in the US using the Exynos variants and they've all flashed the necessary CSCs when required.
Flash TWRP using Odin and then use the flashable CSC selection mod to choose whatever CSC you'd like to flash.

I'll assume that flashing TWRP is going to trip knox, right? therefore flashing a localized CSC is going to require me tripping knox.
Which hey, if Android Pay works fine then i don't need to use Samsung Pay i guess.
If i dont change my CSC, then will my phone receive OTAs when they're released in whatever country its sourced from?
Will changing my CSC to a Canadian one mean i'll start seeing Canadian OTAs?
What about manually flashing official images? Do i have to make sure that the file i'm using matches the CSC as well?
And lastly, are the S8 and S8+ images the same file? Or are ROMs for the S8 100% compatible with the S8+?

Flashing anything other than a Samsung Stock ROM will trip KNOX. Including TWRP. The Canadian CSC using the flashable CSC selector will have no effect on KNOX since it'll already have been tripped because of TWRP.
If you don't change your CSC, and are rooted with Magisk and have mods, you won't get any OTAs since the phone is rooted.
And no, changing to a Canadian CSC will not get you Canadian OTAs since the Canadian variant has the Snapdragon 835 and the 955FD you're getting has an Exynos 8895, so OTAs and stock ROMs are most definitely not interchangeable.
Manually flashing stock ROMs is possible, I suggest you flash the newest one available when you get the phone, which is G955FXXU1AQK7. And honestly, because there's been a major overhaul in how CSCs work on the S8, you can just grab any firmware and flash it and it'll stay on the CSC your phone came from because it can't switch to a Canadian one without you manually doing it.
S8/S8+ images are not the same and you can't flash S8 images on an S8+ or S8+ images on an S8.
Only S8+ (G955F/G955FD) stock ROMs will work on your phone.
However, since you're going through all the effort to root, change CSC and flash Magisk Mods, might as well use a custom ROM?
They get updated regularly so you don't have to keep flashing the stock ROM, and you can still have root, CSC mods and everything but with a few extra features and possibly better performance.

I got my S8+ over Thanksgiving and have been using this for less than 2 weeks. I received an OTA update a few days ago. It was an Android security patch dated November 1, 2017. So, I am getting security patch updates.

So maybe the first think i do is try and see how long i can go without having to root it / put on TWRP.
If i dont touch anything, including the CSC, will i receive OTAs as the source country gets them ? or am i out of band and therefore am on my own?

Just got the phone!
It's CSC is XSG/XSG/XSG which looks like "United Arab Emirates unbranded"
First thing im noticing is that it's not restoring my Google backups
Is this because it's a samsung phone and i need to use the Samsung backup feature instead?

It's CSC is XSG/XSG/XSG which looks like "United Arab Emirates unbranded"
First thing im noticing is that it's not restoring my Google backups
Is this because it's a samsung phone and i need to use the Samsung backup feature instead?

It is indeed a UAE phone, good place to be sourced from since XSG gets updates fairly quickly compared to other CSCs.
What issue did you face when restoring the Google backup and how exactly did you try to restore it?
Some people have reported that the Samsung Pay app installed on XSG phones works well in other countries, so you can try that out if you want, otherwise Android Pay should work fine.

Thank you!
Yes, i actually just got a notification for an OTA. I think the December security patches.
Which is aweosme, so i'm not going to flash a different CSC because i dont think i need to at this time!
Regarding the backups; I was expecting to log in to this phone and get all my apps that were installed on my last phone.
But then i realized that htis is a brand new phone and i dont have a backup to restore to!
So i just manually installed the apps i needed and was on my way.
Lastly, yes, i just installed Android Pay and it works perfectly fine.
Thanks for all the help!

If your previous phone is an android phone and you use Google ID on that phone, you should have no problem restoring your apps. The Play Store remembers your Google ID and all of your apps should be restored if you log in with you Google ID.
Im noticing now that of my 2 SIM cards, one is usually around 80% strength, while the other is around 50% strength.
is this possibly an issue with using the wrong CSC for my region?
Or maybe since only one SIM can use LTE at a time, the other SIM is stuck on 2g/3g and it just has crappy reception becuase those towers arnt really in use anymore in my area?

Yeah, that is probably the case.
I had taken my 955FD to UAE earlier this year, used my local UAE SIM in slot 1 for LTE, and my Pakistani SIM card in slot 2 so I could still get texts on that number. Battery life did take a significant hit since the signal strength on one of the SIMs was quite low.
Changing CSCs may or may not have an effect on the signal strength. A good way to check is by using the SIM with poor signal strength in another phone with the same network mode, and see if you get the same results, if so, changing CSC will do nothing. If the difference is very large, then you could consider flashing the CSC although I wouldn't recommend rooting your phone just for a CSC change, especially if you aren't facing difficulties in making calls/sending texts/using data.
I have a 955FD XSG also. Using AT&T. I managed to enable VoLTE by quickly putting the sim on an att branded phone and returning the sim to my phone. I now have the VoLTE toggle and calls are placed over LTE but I can't seem to get the wifi calling toggle to appear.

WiFi calling won't appear without the AT&T CSC.
Sent from my SM-G955F
Hi everyone. I have a Galaxy S8+ that I bought on BackMarket a year ago. The phone has been great, but has always had problems with some phone calls going straight to my mailbox for no reason, texts not coming in then suddenly working if I send OUT a text. After some research and contacting my provider (United States, Ting), I was told that this is because I need to enable VoLTE. My phone didn't have the option to do so and when I called Ting again, I was told that this is because my phone was the International version and VoLTE wasn't supported on that model.
I thought that was the end of it, but this week I had the thought that maybe this is a firmware thing instead of a hardware thing. Calling Ting again, they checked my IMEI and said my phone should be able to do VoLTE. Great! All I needed was Odin and the right firmware (I was thinking G955U1, TMB). So here's where things get weird. As I started to set up for flashing my firmware, I gathered the following info:
IMEI.info says I have:
Model: G955F Galaxy S8+ (SM-G955N)
Here's the info I get when running the "Phone INFO ★SAM★" app.
Phone Model: SM-N950F / Galaxy Note 8
Firmware's CSC Code: XEF
Bootloader Version: G955NKSU3CRI3
PDA Version: N950FXXS5DSC6
CSC Version: N950FOXM5DSC1
Latest Firmware: N950FXXSDDTJ1
If I'm reading this right, it looks like I've had a Galaxy S8+ running Note 8 firmware? At this point, I'd still like VoLTE, but even moreso, I'd like to just know what's going on and what I should do about it.
Seems like somebody installed a modded Samsung firmware on your phone. Check download mode for KNOX, I think it will be tripped (0x1).
If it is tripped then no Samsung Pay and stuff that depends on KNOX. If you are fine with that and just want to get VoLTE working, download the right firmware for your device and flash it to stock. If stock everything is important to you, I suggest contacting the seller on BackMarket and getting a refund or something if the seller didn't specify tripped KNOX.
BTW, if I remember correctly G955N is the Samsung direct model sold in Korea, so depending on CSC and what not VoLTE might not work. Best of luck
Thanks for the reply.
So I ended up solving this with the help of a few people over on Reddit. Here's what was going on and what the solution was, for others that come across this.
The phone was running v6 of HadesROM. I guess the creator of HadesROM uses the Note8's OS build as his base for the Note8/S8/S8+, which is why the phone was showing up as an N950F. And the phone itself was a G955N, which is a Korean model.
At the direction of a few people on Reddit, I used TWRP to re-flash with the newest version of HadesROM and set the Firmware CSC properly to a US Carrier.
When the phone booted back up, the VoLTE setting was present in quick settings and works great.
I purchased a Z Flip 4 (SM-F721U1) from Samsung US for use in Canada. Everything works perfectly, but I can't add my Canadian debit card to samsung pay. Funny enough, my Visa and Amex work without issue.
When I try to add my debit card, it tells me that the card information is invalid.
I've read that since it's a US phone, Canadian cards won't work in Samsung pay.
Is it possible to flash a Canadian firmware on the phone so that I can use my Canadian debit card? This worked flawlessly previously on my Z Flip 3 and S10+ (both purchased in Canada).
Yes you can! Just remember when you flash in ODIN to flash the CSC file and NOT Home_CSC.
Note that for some reason VoLTE and WiFi calling do not work still.

Great! Are you saying that wifi calling doesn't work on the canadian firmware? It's working on my current firmware and, previously on my Canadian zflip 3, there were no issues at all either.
In any case, I'll give it a try, worse case scenario, I'll flash the US firmware back on it.
Thank you!

Correct - I tried registering VoLTE on both the US firmware and Canadian and it won't register correctly (IMS always says not registered). Telus (my carrier) is saying they don't support this because the IMEI is showing a U1 model, but I know it should work correctly. I just don't know what to do to get it resolved.
Anyways flashing the XAC firmware allows you to use any of the Canadian Samsung apps including Samsung Pay.
Amazing, hopefully I have better luck on Rogers.

Let me know - it could be something Telus changed on their end.

backed up via smartswitch, flashed 721w firmware (XAC), restored.
All is good, able to use credit cards and debit cards, wifi calling and VoLTE are working as well.

Lucky! I think Telus is just tightening control on how they whitelist IMEI's for their service, which is unfortunate.

I might switch from Telus to Rogers just to be able to use VoLTE and VoWiFi with US models. Absolutely crazy how Telus started blacklisting IMEI's for US models (I submitted a CCTS complaint but I bet you that does nothing).
