I've been searched for few days and try my best not to ask this stupid question. But seems like nobody cares about it or everyone know the answer except me....
So, here is the question:
The CSC code you talk about, looks like have three different "status" at least. The csc code found in download mode, the csc code found in recovery mode and the three codes found in "SETTINGS>ABOUT PHONE>Software information>Service provider", what EXACTLY did they mean?
I know there is active csc, firmware csc, original csc. For example the three CSC codes found in Settings, XAS/XAS/SPR, which is active csc? which is firmware csc? which is original csc?
Additional, I can't change the last csc code XXX/XXX/SPR, right? And in recently firmware, the active csc code seems like could change with SIM card inserted. If this is true, can I assume that there is no difference among USA's Carrier versions whether in hardware and in software?

From what I recall, when I initially got an S7 was that the phone had been made in Korea and the CSC region code was for China (first CSC), and the carrier (second CSC) was for I can't recall the phone companies name in China.
Even with the CSC described above, the phone worked just fine in the US. Never the less I changed the CSC by flashing. I chose the first CSC to be XAA (USA), for the second CSC I had the option for ATT, Sprint, etc so I could have used a specific CSC for a specific carrier, right? (yes)
But instead I wanted my phone to be more generic, because I wanted an easy method to allow for any US or European/other national region GSM sim, somewhat like an international phone yes?, so I chose XAA (generic sorta carrier) for the second CSC.
The original phones CSC can show up in an app which shows the phones origination, etc, but since the 'active' CSC is XAA/XAA, the original birth CSCs don't really matter any longer.
If I put in an ATT sim, remember I'm using a generic carrier CSC of XAA, the CSC will not change, though my phone will still work ok. If I put in a T-Mobile sim, it's the same, the phone still works but the XAA CSC stays the same.
I could flash the ATT CSC, and because my phone is a GSM phone, it would still work with a T-Mobile sim, but I might not get any special T-Mobile abilities, since the ATT provisioning may has some enabled extra services that T-Mobile might not have. I could flash the T-Mobile CSC and the same would apply if I inserted an ATT sim.
I'm not aware of the phone companies in the US yet making all their GSM phone compatible with each other by a simple sim switch (is that called e-sim or something like that?, though I understand that the hardware may be in many newer phones, but software disable. I believe there is a current law suit and or an FCC complaint regarding the issue or collusion by several phone companies, as with the phone companies 'disabling' a simple sim switch to change companies, makes is more difficult for users to easily change phone service providers.
As usual, most US companies do what they can to make things more difficult for their customers, and our government does little to stop them. We sure could use Europes more friendly citizen advocacy and better pricing, increased privacy and control of our personal info, as well better service for public utility, internet and phone services. Europeans just don't put up with the s**t like US citizens do.
So going back to your original post, the active CSC is what you need to pay attention to in order to mate that with your current region and service provider. The original CSC info, from my perspective, might only be useful if you wish to return a phone back to it's stock birth status.
Anyway, I hope this helps answer your question.
I know this is a really old post, but I was digging in to know about the Service Provider... I have XAA/XAA/SPR on my SM-N960U (Note 9), I'm outside of the US I'm living at Central America, so when I just came here I bought a Sim-Card from here and All works fine, now. I'm trying to Update by Odin to Android Pie, but I don't want to mess up with this important part because I will still live here during the following year. so, you think there is a possibility of messing this "sim-Unlock" by upgrading? hope you can answer this post I know it's being a while since the OP.
so did anyone find out how to the change the 3rd CSC code. eg i can convert a VZW/VZW/VZW to VTR/VTR/VZW. But how i change that last VZW to VTR also. Some say it cannot be changed, but others say i can be.
im coming from a s8+, where you could flash the combination files etc.. and end up with all three same csc codes on the phone eventually.

Hi,
(I'm quite new to all of this.)
I installed android nugat on my Samsung Galaxy S7 SM-G930F using this guide: https://forum.xda-developers.com/galaxy-s7/development/rom-superstoc-rom-v1-0-aroma-t3496520.
And I currently my sim card is not able to connect to network, after insertion of the sim card, I pass through sim pin. Sim is loaded by phone. On the locked screen it says 'Just emergency calls'. When I try to call anyone, it says 'Not registered in network'.
Already tried two different roms, even Samsung Switch Emergency Software Recovery and Initialization.. nothing happened, the problem is still there, not able to use any mobile services.
Did find that my IMEI is not the same as on the back side of the phone.
Samsung Serial Number is equal with back of the phone.
CSC CODE INFO:
PRODUCT CODE: SM-G930FZKABTU
ORIGINAL CSC CODE: BTU
FIRMWARES CSC CODE: BTU
ACTIVE CSC CODE: BTU
AVAILABLE CSC CODES: BTU, CPW, DBT, ITV, KOR, NEE, XEF, XEO, XEU
CSC COUNTRY: UK & IRE /GB
MOBILE OPERATOR: 23002
I also find that the android says that it is G930FD (dual sim version), even though that on the back of the phone there is written G930F, and obviously there is no way to put second sim inside.
I'm in Czech Republic and I've Vodafone. Everything worked perfectly fine before I started messing up with the roms. Do not know whether the IMEI was different when it was working.
Could anyone give me some advice how to fix it?

Hi mate
Where did you get this phone from??
The imei is not right and the change for sure is not caused by flashing the custom rom , flashing the custom rom probably caused that the original Imei resurface , first imei belongs to a totally different phone:
Model: DIAMOND
Brand: XTOUCH
IMEI: TAC: 359007 FAC: 07 SNR: 042596 CD: 4
The second one it does belongs to an S7
Somebody changed the Imei ...usually this is done when the phone is stolen.......maybe that is why is banned
Take the phone back , the phone was working fine because you had an Imei from and old phone ....the original imei is probably reported stolen
Not glad to here that. I bought it from some guy, there is no way for me to put the phone back.
Is there any way to make it work? Next time I'll rather buy brand new, but once I have it, and money are gone...

i though i was in a similar situation i thought my s7 was hot because of a old text i found on it. and i later found out another phone the girl had was stolen not my s7 so i got lucky. basicly without equip like octoplus box changing its not gonna happen.

If you have any form of receipt / chat with your seller, your best bet would be to print everything and go to local authorities. It's a slim chance, but a chance nontheless.
It might be the case that the seller banked on you not changing your rom etc.
It's most likely a stolen device and yes there are ways to make it work again, which won't be discussed, since it's illegal and also any IMEI should not be posted here as mentioned by the previous poster. As you found out, you can easily backtrack IMEI information. This time it worked out for you, but usually it just get's you into trouble.
And even if you don't have anything at all, still go to the local authorities and explain it to them. If the original owner of the device tracks the IMEI, which you accidentially reset, you might get accused of being the thief, even if you did not do it.
Next time you buy something used, ask for an ID copy (depending on country) and make a receipt with price, IMEI and you and your sellers data (Name adress etc).
If **** like this happens again, atleast you will be on the safe side. And even then.. sometimes it's better to save some more money to get a new device from a store (full warranty etc.).
It`s the only tips, i can give you now. But i do wish you the best of luck.
Thanks for answers!
I'm just wondering, if the imei, would be marked as stolen, and I would restore the original one by flashing the rom, wouldn't be the imei displayed in android, the same as is on the back of the phone?
Just installing rom wont change IMEI!
Sent from my SM-G930F using XDA-Developers Legacy app
I basically tried to install APP, BL, CP, CSC using Odin couple of times (have tried: Czech Vodafone 6.0.1, Czech O2 7, Germany Vodafone 7, SuperStock-Rom_SM-G93XF_V2.4, that what I remember). Once also tried to clear data using twrp and root it. Also once I messed up the installation, so I did Emergency software recovery and initialization using Smart Switch.
Since updating to Android 7.0 on SAMSUNG S7, the SAMSUNG call/phone icon no longer notifies or display for me missed calls. I've to rely on a third party truecaller for the notifications. I'm not used to this and as a result I've missed to respond to very important calls.
So can anyone tell me what these region codes like LRA VZW mean?
https://samsung-firmware.org/model/SM-G930U/
Which one should I choose? Bought a Sprint S7 in China(coz it's twice as cheap as those sold in China). Use the local CMCC network. I did install the TMK version. Works fine except for a few minor bugs. I'd like to know what these other region codes stand for.

The codes represent the country/region and/or the mobile carrier/network the device is to be used on.

Could you be more specific as to what each of these code names stands for? All of those downloads are for G930U, which, unless I'm mistaken, basically means these softwares are found on the UNLOCKED S7's and that once installed, no matter where you bought your S7 from, be it Sprint or Verizon or AT&T or whatever, your phone should behave just like an unlocked S7, independent of any carriers(or regions?) So what's the difference between, say, G930U SPR and G930U ATT? And what about all the other ones, like LRA XAA ACG AIO VMU...? I can't seem to google anything out about them. Can you shed some light on it? Thanks
I would've posted a screenshot of the linked page but from my phone that seems kinda hard. Sorry for the inconvenience!
I have been reading here on XDA and elsewhere on the 'net for a couple days on and off trying to figure this out...
I'm American but I live in Europe. I had an s8+ from the USA and used Samsung Pay without difficulty. My phone was stolen and I replaced it here with the SM-G955F model with SEE/SEE/SEE as my CSC and was dismayed to discover the world of Samsung region-locked apps.
I was going to flash a stock ROM from the UK (where XEU CSC allows SPay, as I understand) but upon further research realized that both SEE and XEU are on the OXM multi-CSC ROM. So I'm not really getting anything different by installing this ROM and various threads have said fairly authoritatively that I will NOT get the XEU CSC by installing that ROM.
QUESTION #1: Is that accurate? Although some posts said "NO" quite authoritatively there were several that seemed to think it would work. I don't want to go to the hassle of flashing a ROM and restoring everything if it's pointless...
So I went on and researched multi-CSC further and read some articles and posts that indicated that all I need to do is put in a UK SIM card and factory reset my phone and it'll ask me to set the new CSC when it comes back up (since XEU is part of the OXM multi-CSC ROM). The bad news is that I don't have a UK SIM card, but the good news is I've got several friends from the UK and could probably chase one down if this has a high likelihood of success. As before, though, several posts and articles indicated this did NOT work.
QUESTION #2: If I get a UK SIM card and put it in and factory reset my phone do I have a pretty good chance of getting a new CSC?
The final direction my research has taken me is into combination files (https://www.sammobile.com/forum/threads/39155-How-to-change-CSC-with-a-combination-file). Really tough to get an understandable intro to what combination files are and how they work, but if I understand correctly it's like flashing your phone with a utility ROM that doesn't act as your phone but will potentially make changes to your phone, like resetting the CSC. Of course it's the usual mixed bag of some posts saying it's a silver bullet and others saying it doesn't work at all.
QUESTION #3: If I lay hands on a combination file (is that the right term?) that sets the CSC is this a fairly sure-fire way to go?
QUESTION #4: Of these 3 options which do you recommend?
Some of you might recognize me, used to be pretty active in the root/mod/ROM game back from the days of the OG Droid on, but have been away for a while. Now I've got a new Samsung S10E, and I don't quite get the relationships with the versions and trigraphs, etc.
My phone is a G970U1 - which I understand is a non-carrier specific unlocked model? But the Service Provider SW ver. reads SAOMC_SM-g970U1_OYM_TMB_PP0022 with TMB/TMB/SPR tags? What's the OYM? And what's up with the two T-Mobile tags followed by the Sprint tag? I did some digging around but couldn't see where there might have been a guide/explanation in this forum... pointers would be fine if it's too much of a pain to explain the whole thing here.
Also, OTAs? Would those come from TMO because of the tags, or from Samsung because of the U1 instead of the U?
Thanks....
For others' benefit: OYM is multi - covers multiple options depending on what SIM you toss into it. And the OTA question was answered a few minutes ago when I picked up the US Unlocked update from Samsung.

If you have an unlocked S10e model, then you shouldn't have SPR at the end. It should be XAA. For example if you put T-Mobile sim in your unlocked phone, it should read: TMB/TMB/XAA, meaning that you have an unlocked US model(U1). If you put another US carrier sim in the phone, then first 2 TMB/TMB will change to that sim, such as ATT, VZW, USC...but the third XAA will stay the same. If your phones shows SPR, then it should be Sprint branded model that was flashed with U1 unlocked firmware. Basically US carrier firmware has OYN in the Service Provider SW ver. and unlocked is OYM.

Thanks! That's exactly the kind of knowledge I was looking for.
So... my phone was somehow hijacked from Sprint and reflashed as unlocked somehow? It arrived in factory shape, including all the little plastic protective bits that you have to spend fifteen minutes peeling off, tearing open, etc., etc., etc...

It isn't an issue if the phone was flashed. So if you were planning to buy a factory unlocked model, then it isn't the case but nothing to worry about.
Back when S8 was a Samsung flagship, there was a news that Samsung is planning to make the firmware more universal(at least in US) and if you have a carrier branded phone and you put another carrier's sim, then it would automatically apply that carrier's settings + download any bloatware.
Been searching the forums and have not found a solution yet.
Current Situation: Have a Note 20 Ultra US Verizon verient, SM-986U, Verizon Unlocked.
Current Issue: When ATT, US Cellular ect. SIM card is inserted, device will not recognize it and won't switch to new carrier.
Reference: Have a Note 10 Plus that is unlocked from verizon and currently accepts and reprovisions based on sim card.
Question then is, why is the multi csc note 20 from verizon not behaving the same way.
First thing would be to verify it's actually unlocked.
Second would be to perform a factory reset with the new carriers SIM card installed.
It should definitely see the new SIM after that.

Talked to maybe 7 verizon agents all teir 2, all confirmed its unlocked on all levels, (network, financial).
Talked to samsung and they say its locked to verizon, but not able to say how.
I have done what you mentioned as far as reset with different sim. I can also include that the other note 20s i have show same thing.
Have you verified that you actually have multi csc. May have to flash u1 firmware.

In Google dialer do *#272*YOUR_IMEI* that will pull up a list of csc that the phone can switch to. Don't change anything there and just cancel out of it, but can just verify that way.
Sent from my SM-N986U1 using Tapatalk
Carrier switching historically speaking is included in a firmware update that occurs about 4 to 6 months into the product life cycle.
Yeah am thinking without U1 firmware, probably won't happen. They have probably blocked the other csc somehow like they like to block everything else.

Hmm and thats what i worried about, might be to soon for auto switching, about 2 weeks ago the *#272* code did let me see the list, i didn't select anything with not being familiar with it, but no longer works, dialer won't accept. So bottom line that i'm thinking is give it a few months and should get update else flash U1 firmware to get around it.

Thanks all for answering, so what i have found out is the following.
1. SM-N986U is Multi CSC " Verizon, US Cellular, ATT, Ect".
2. *#272*IMEI# will not work in phone or google dialer for some Loaded CSC configuration. "VZW,USC,ATT".
3. Using Google Phone, *#*#27262826#*#* does in fact work on all configurations of csc U or U1 variants.
4. I did confirm that my device was unlocked but firmware csc has to manually be changed with dialer code. I was able to move between all loaded CSC with boot screens and network configurations.
5. We are currently waiting on samsung to push patch for sim auto recognition for CSC rebrand.

Dialed *#*#27262826#*#* on my unlocked Tmobile
Reading a bit more here.. So, I bought a N20 Ultra (SM-N985F/DS) unlocked, I'm currently using it in Colombia, the CSC code for this device is TPA (Panama). I want to change to generic unlocked (don't know if there is such a CSC) or a US unlocked not branded one... In this case is there a way to do this without ROOT/messing up KNOX? I travel quite frequently to the US and I enjoy using SAMSUNG PAY which is disabled (I get a message saying SAMSUNG PAY is not supported on my phone).
I do realice there are quite some threads on this CSC but I haven't found one that has the answer I'm, looking for (maybe not searching properly). Any guidance on where to look is more than welcomed.

Hi, wondering if you ever got this figured out, i'm in similar situatuin. I live in the Caribbean and bought the N20 Ultra (SM-N985F/DS) unlocked, has CSC code TPA. I want a global or us unlocked CSC or firmware so I can enable e-sim as I travel a lot. It is incrediby annoying that the phone is advertised as Esim enabled but many variants still dont have this activated.

I have tried dialing *#*#27262826#*#* in stocks phone app and Google phone app with no luck.
U1 model, CSC - ATT/ATT,ATT/XAA
I desperately need to be able to manually select my bands and the last Samsung update broke the permissions for the shortcut maker app I was using. I live on US/MX border and I cross every day and my phone is constantly changing bands and some are incredibly slow, it's killing me. Any help would be appreciated.
With newer os versions, we are unable to manually change CSC on devices using dialer codes, only way is to use a 3rd party csc changer. I would not recommend unless you know what your doing.
