I have purchased an unbranded G930F from B&H for use on AT&T in the U.S. The phone currently seems to work fine with AT&T LTE, here is what I've determined using Phone Info and About Phone:
Country: Panama
Product code: TPA
PDA: G930FXXS1APG3
CSC: G930FUUB1APEQ
Baseband: G930FXXU1APEQ
Now I'd like to reflash my phone using Odin to fix some software issues from OTA updates not resolved by factory reset. From what I gather, I think the proper thing to do is flash the latest firmware from SamMobile (any region) and extract HOME_CSC from the current Panama firmware. I've read a lot of other guides and threads but a lot of similar questions are unanswered or refer to deleted posts on other sites. So here goes:
1. Does CSC affect my phone automatically working with AT&T LTE in the U.S.? Should I make sure to keep using the Panama CSC since it seems to be working, or does it not matter? If it does, is there a list of certain CSCs that are compatible with AT&T LTE or a specific preferred CSC for AT&T users? Does the CSC need to be for the same model S7 (ie. can I flash a CSC from a Snapdragon model firmware with a G930F firmware)? (found out that requires root, which defeats the point of remaining stock/untripped KNOX)
2. Will flashing a more up-to-date firmware for a different region also change the baseband, or can I safely flash a new firmware while leaving the baseband intact? Similarly, will flashing a more up-todate firmware/baseband for a different region possibly break AT&T LTE? Are only some basebands compatible with AT&T?
3. I don't have Samsung Pay on my device, but I found mixed info saying that UAE and UK firmware include working Samsung Pay. Are those the only ones that do and will either of those affect AT&T LTE functionality or other software features? It's not critical but would be nice to have.
4. I see some custom firmwares list VoLTE support, are there any stock firmwares that do that would be AT&T compatible? Once again, not critical but it would be nice. (seems it's not worth the hassle)
As far as I know, there aren't any firmwares for the G930F that lock out the AT&T bands. You're fine using AFR, XSG (UAE's firmware), and AMO for your csc to use samsung pay. AMO (Spain) has the whitepages feature if you should want it, but I think that MST pay in AMO doesn't work (I don't use that firmware, so can't confirm). I use UAE's firmware and have no issues with the latest release and pay/framework. I've made plenty of MST payments all with no issues. To my knowledge, your baseband firmware does not need to be preserved at all. I recommend you do a complete reïnstall of the UAE firmware and flash everything to avoid issues. I'm on AT&T and have yet to have had any signal issues.
As an aside, only the USA has "4g LTE". The rest of the world calls it 4G. Your status bar indicator for data strength will always show 4G in international ROMS for this reason. In case you were wondering, "4G HSPA" is actually 3G or H/H+ in the rest of the world. United States carriers rewrote the definition of data speeds in the united states so that they can get away with selling lesser services than the rest of the world. Telecoms in the USA are among the worst in the world, so congrats :victory:

I'm new to the forum and phones in general. This was helpful but I'd like to ask a few questions to clarify.
I purchased 2 phones off eBay for use on at&t. One of them came with a UAE baseband G930FXXU1BPJG and one came with G930FXXU1APB4 (which I can't find any info on) The second.. APB4 displays LTE, but the UAW firmware only shows 4G. I just assumed it was not using LTE, but your post seems to indicate that it might be. I never actually ran a speed test, which I will do.
1. How can I get the APB4 on both? I haven't been able to find a download for that or even a google result.
2. Why did the AT&T rep have to manually change my IMEI number in their computer to one for an AT&T s7 before the UAE firmware would even negotiate 4G (it was stuck on H) ?
3. If download speeds on the UAE phone aren't LTE do you have any other ideas I can try?
Thanks in advance for any help.

The CSC is the part of your rom that is specific to the local carrier, e.g. VOD for Vodafone. A list can be found here (http://forum.xda-developers.com/wiki/Csc) but is doesn't seem to have XAR or XAC.

XAR = Cellular South
XAC = N/A
Anyone figure this out?
There still hasn't been an answer as to exactly what the difference between XAR and XAC is.... Anyone figure this out yet?

The only thing I'm coming up with is XAR is possibly non modem or USA based and XAC is modem based and outside the USA

XAR is the version for USA. XAC is the version for Canada.
CSC explained, such as it is, incuding what XAR and XAC mean
Stock OTA update or roms (generally speaking) has to match your specific csc on your devices stock firmware build.
The three letters after the model number signifies: 4 meanings, all valid indicating very different things. The hard part is deciphering what your CSC means and how that effects primarily your ability to upgrade correct software, whats bundled in it and maybe a hint why your not getting a OTA update.
1) the country or region(s) a model was bundled for (often csc for a tablet identity) XAC Canada, XAR Cellular south of USA
2) The carrier product code is firmware bundeled by every cell provider . Each has thier own and a different csc code even when a parent company is servicing a different country or region(s) within a country, Think Virgin Mobile in Europe, UK, USA etc... .
3) The consumer specification code . These are either bundle software by options.. of say Samsung G3 vrs Samsung G3 lite, or Italian vrs English, or Both.... consumer type, app and use options... basically limitations or exceptions between software bundles for same basic model depending on where its being sold. You know, bells, whistles, cultures, even age, sex and race user groups can require important distinct features between standard stock builds multiplied by makes and models. Targeted software, use, design..
4) The customer product code. So you bought a device off web, on sale, not affiliated with any carrier, specific country or region, bulk generic bundles. Eg. travelling abroad with your tablet bought generically over here or buying a GS5 in Tokyo airport on your way home to USA.
Why is that a problem? Depends where you physically are, with a device from? With certain customisations or exceptions and how does OTA connect via unfamiliar local data access but foriegn from the csc perspective. USA CARRIER but Japenese csc...
I suck at explaining but read article I reference down below.... Burners are probably in this work around .
Be certain the build+model+csc is same before choosing a flash rom or upgrading your stock firmware. Odin, Kies etc will likely refuse to flash/sync/upgrade if there is a mismatch in csc more often than any other reason
Here is a helpful, current and informative blog by Wilma Dee that explains csc much better, some great work arounds, csc troubleshooting and major carrier code plus country code lists,
Since I'm new here, I dont know her, I wont post a link but I really feel this paper is worthy of XDA scrutiny and appreciation. Search Google with this title, posted April 15 2014.
How To Change the CSC Code on Samsung Galaxy S5
These are not complete lists, they are Samsung specific, GS5 specific. as she lists them and its alot.
Are the country codes at least unified between all brands? I dont know but not likely.
There are different brands, with differently configured tabs and cells, in different countries and several distinct regions within each country, many data carriers with subsiduary carrier companies in diferent countries, regions, languages, configurations etc etc etc.
No wonder answering what does CSC stands for, means for your device, lists of codes is so hard to do .
So I have this S7 International version and I've been reading a lot and realized that my CSC is ECT for Nigeria NG I'm thinking this could be why my data is so damn slow compared to my HTC.... Is there a way to change this and how would I go about changing it... I'm on MetroPCS (T-Mobile) in the USA.
Thanks
go to sammobile . com and download the firmware you want and use Odin to install. Theres plenty of other software, whether it's UK, Luxemburg or any other. Plus you can get the latest April security update
I just wonderin what's the best country, I was thinking Austria T-Mobile but honestly I don't know much about Foriegn carriers
But seriously I waited 4 hours for a 2GB file to not gethalf way done I just stuck my sim in my HTC and it's halfway done in 5 minutes
Make sure whatever you download is of the 930F variant and not any of the snapdragon firmware. Most US based ones are of snapdragon type.
I know that I was just wondering if it matters what country I download whether it's Austria or Germany Poland UK etc
Holy crap this has fixed everything. I now for the first time have an LTE signal. Unfortunatly it's not rooted anymore but I"ll take being able to use the internet over having a linux distro on my phone any day
Glad to hear you sorted the problem. Best way to select ROMs is to look for countries with matching LTE bands to your carrier. Most likely case is that CSC might limit bands or do something on that area.
I have a greymarket import S7 Duos with the CSC OJV (which is either middle east or africa depending on the source) and it still hasn't received the June firmware update. I'd like to switch my CSC to get timely firmware updates. Does it make any difference which CSC I use? Is there any that would be best based on update timeliness and/or compatibility with US carriers (T-Mobile/AT&T)?
Also, is there any way to download stack firmware images direct from Samsung rather than going through shady third parties?

India is a good option as they get updates very often , compatibility? if your phone is working fine now it should work fine with any of this...
CSC change, you have to do a factory reset
Check this thread , it shows you how to change csc or flash a newer firmware without waiting for the update (odin) BUT you should do it with G930FD firmware there they use G930F firmware , the basics are the same
http://forum.xda-developers.com/galaxy-s7/how-to/official-stock-firmware-update-odin-t3369431
This thread says that the single sim firmware and dual sim firmware are interchangeable. Am I misunderstanding something?
As far as carrier compatibility, the phone works, but I don't have visual voicemail. Also not sure if I'm missing other features like VoLTE.
The Spain firmware has wifi calling and Samsung pay. I don't know if you can make wifi calling work but you can tweak Samsung pay for USA market.

Same here. On the FD version.. My problem is dual SIM not really working. Yes, I have two numbers and. That's about it. Data doea not work. Disabling SIM2 and. SIM1 works LTE on AT&T. No VoLTE obviiusly so I can't comment about it. With an xposed module, my Android pay works. You will most. Likely won't be able to make Samsung Pay work. I did a massive reading and can't tell you one person that was able to set it up and use it in a store . my advice to you is forget about OTA. Don't be scared about the Knox bit, trip it, and install TWRP and a custom ROM. those get normally the latest firmware in them, with recent security patches, and some of them are even OTA by themselves. You can also hey rid of tons of bloatware this way. I wouldn't bother dealing with changing CSC from Egypt to India. Since you are already at XDA I guess you know what to do.

If you boot into download mode, the phone will even display G930F as its model number. You can run F firmware on an FD without issue. As for the dual SIM working, I haven't tested it, but I did read that SIM1 has full connectivity, while SIM2 is limited to 2G/3G. You can't have two 4G SIMcards active at the same time.
I'm running Samsung pay perfectly fine on UAE firmware. Samsung pay is unfortunately firmware dependent. However, if you trip KNOX you're not going to be able to use Samsung Pay ever again. And to be completely honest, if you're not using Samsung pay, you shouldn't be using an S7; get yourself a better phone like the G5/Nexus/V10/Moto X. The S7 lacks a lot that other phones bring to the table, assuming that you don't care much for photo quality.

Would wifi calling work on US T-MOBILE?
Same question here. I'm using Tracfone and T-Mobile sim cards, and my G930FD is from United Arab Emirates. There is a Islamic calendar in the S Planner which I was unable to get rid of, so I found the UK firmware and CSC from Sammobile. After flashing those files to phone, the Wifi calling and Samsung Pay still won't work. Otherwise the UK firmware works fine, since there's no bloatware or funny stuff(like calendar from other country). Dual sim works with no issue too. Still hope to find a better CSC file for Samsung Pay and Wifi Calling.
My G930FD is a Singapore set and Samsung Pay has been available for quite a while now.
I recently flashed the UK BTU firmware, seems to have less bloat but Samsung Pay isn't available, side loading didn't seem to work either.
I flashed the UK firmware hoping to get faster security patches, so far still on July. But not sure if just me, but phone feels a bit snappier and fingerprint sensor seems more accurate on July vs June's.
Where are you all getting the stock firmware for different countries?

When you had the Singapore firmware, did you actually use Samsung Pay successfully? I have a 930FD that is for the UAE, but Samsung Pay wasn't on it and it didn't work when I sideloaded it. I flashed it to the the BTU version and was able to sideload it and log in, but it won't take any of my credit cards here in the USA. Also, the signal strength on AT&T is much weaker than another phone that I have that is made for the American market.
Should I try to find a firmware that is still located in the same region as the UAE with Samsung Pay and without the annoying bloatware the UAE mandates for their phones? Would India be good?

Samsung Pay worked when I was on the SG firmware. It also worked when I flashed the Australia unbranded firmware, even though I was in Singapore. By working I mean I'm able to add cards, make contactless transactions and so on.
So Pay should work on any firmware that it's officially available in, regardless where you use it.
I would try Australia, minimal bloat. F / FD firmwares work interchangeably.
Hi,
I just received my unlocked G930F from B&H today (What a beautiful phone).
Exynos 8890 Octa-Core Chipset
According to "Phone Info" this was made on 2016.07.09 and assembled in Vietnam.
Product Code SM-G930FZKLTPA
Firmware code & Active code: TPA
Aavilable CSC codes: ALE, ARO, BVO, CHO, COO, EON, PCW, TPA, TTT, UPO, UYO
CSC Country: Panama
Mobile Operator: Home / 310410
I am located in New England.
The two Mobile Network types I have seen displayed so far under the SIM Card Status are; LTE and HSUPA
I did a manual update today and the current version is:
G930FXX1APG3/
G930FUUB1APEQ/
G930FXXU1APEQ
I have been trying to read as much about this version of the S7 as I can so I don't have to ask too many questions, I do have a few at this time though. My S4 was also on Straight Talk and would not update past 4.2.2 I needed a more reliable phone so now have this S7. I want to get all the security updates as well as any of the Android updates as they become available. Straight Talk is not so good about sending updates and I understand AT&T drags their feet on update certifications. Also, it appears some countries are more likely to get updates than others. I understand the UK gets frequent updates, I am not so sure about Panama.
I've read inserting a SIM from another GSM carrier such as T-Mobile even if not activated will allow updates via wi-fi; does this work to get the newest updates?
I want to keep the stock Samsung firmware for the moment & with that, is updating from the phone my best bet or is there a better way to get the latest updates?
Is there any benefit to having the CSC country reflect say, the UK or the EU as opposed to Panama? If so, is there a reasonable way to accomplish this & could you provide a link for me to look into it?
That's it for the moment, I have more reading to do...
Thanks!
Hi,
I'd appreciate some advice. I have rooted and flashed an old Samsung S3 before for a friend so he could play Pokemon Go - I wouldn't say I really understood what I was doing 100% but I followed some instructions carefully and it worked. But that was on an old phone that he no longer used so he wasn't concerned about bricking it.
But this is my current problem.
I am in the UK. In November I purchased a second hand Samsung S7. It was unlocked but had a THREE network splash screen. I knew that I was going to use Vodafone as my provider as I already had the contract so I wasn't over the moon about the THREE splash screen but in my ignorance (this was my first Android phone) I figured it was just an annoyance that I would only see on the rare occasions that I rebooted my phone.
However, I'm beginning to understand that there may be deeper issues, for example
1 - Vodafone keep sending me texts saying that WiFi Calling is enabled, but I don't have the setting to enable it in my Phone>Settings.
2 - There doesn't appear to have been any updates to the phone (including security patches) since I bought it and stuck a Vodafone SIM in it
3 - I haven't received notification that Android 7 is available - Vodafone were supposed to have released this a week ago but I am aware that the roll-out may have been put on hold
I'm guessing the problem is that although my provider is Vodafone I'm not getting any of the nice things they are rolling out (such as WiFi Calling) because my phone has THREE firmware.
But I don't seem to be getting anything from THREE either - this could be because they are just very slow but I am concerned that I won't ever get anything from them because I don't have a contract with them.
When I try to manually update I get a message saying that there are no updates and the following
G930F XXS 1BP K6
G930F H3G 1BP I1
G930F XXU 1BP JE
They all seem to be UK codes and I believe that H3G indicates THREE.
Is there anything I can do. I appreciate that I could just root and flash to standard firmware but I am worried about bricking my phone (it wasn't a cheap purchase) and that I would lose features like WiFi Calling (not that I am getting them at the moment). What about changing the CSC code to Vodafone - is that easy/safe - would that work?
Appreciate any help or advice.
Cheers,
Nigel

Try to download firmware from SamMobile.com and flash to United Kingdom (BTU) my phone was locked to three and I did that. You don't need root and it is highly unlikely that you will brick your phone if you follow the correct steps

I've had a look at SamMobile. Would you please explain what the different downloads are.
I want to stick to MM 6.0.1 for now. I can see three possible options
BTU - the one you suggested
H3G - THREE, not really an option because it is what I have at the moment
VOD - Vodafone, as that matches my contract
Want is BTU? - I'm guessing that it is an unbranded variant, although my daughter's S7 is unbranded and her phone shows it as XEU (which is listed as United Kingdom / Ireland) on the SamMobile site.
What about going to VOD - would that make sense as I am on a Vodafone contract so it would align better with services that they make available, such as WiFi Calling.
And finally, what are the implications of installing a new firmware - will it reset my phone and remove all applications and data. Will there be things that won't work because the system will detect a firmware change - thinking security things like WiFi Calling or Cashless Payments (not that I use them)?
Cheers,
Nigel

Hi Nigel,
BTU is the unbranded UK firmware. I would suggest BTU over VOD just because you don't have Vodafone splash screen or carrier apps. You will also get OTA updates allo5 faster.
There are no implications of flashing a firmware. It will not void your warranty or trip KNOX like root will. You will still have access to all the features of your phone.
Many thanks for all the advice. Going to bite the bullet and load some different firmware.
One further question though - do you know if BUT supports WiFi Calling.
Cheers,
Nigel
