Galaxy S7 shows SM-G930T at the back, SM-G930F under settings, QS 820 chipset - Samsung Galaxy S7 Questions and Answers

Hi,
I got myself a refurbished Samsung Galaxy S7 (flat) but after small examination I realized that there are a lot of inconsistencies, After some research I didn't find out a clear scenario from anyone else so I decided to share with all you so that may be one can help me figuring this one out.
So at the back of the phone its written SM-G930T, while when opening About Device under Settings the model number is SM-G930F. But also everywhere there is a taste of Verizon software (example under Access Point Names there is one APN which is disabled with name "LTE - Verizon Internet with APN VZWINTERNET).
Antutu results range around 132420 to 135500 and it reads the following under My Device:
SM-G930F
Basic Info:
Brand: Verizon
Model: SM-G930F
Device: heroqltevzw
Board: msm8996
Hardware: qcom
Android: 6.0.1(64bit)
Renderer : Adreno(TM) 530
Resolution: 1440 x 2560
Rear: 12.2MP
Storage:
RAM 3307MB
System Storage: 22.83GB
CPU
Architecture: Qualcomm Kryo LP
Type: 64-bot
CPU Cores : 4
CPU Clock Range: 1190.4 ~2150.4MHz
CPU-Z also state the same like Antutu.
What I want to know is if there is anyone else with situation like mine, and how to go about when you want to update to Nougat or which ROM should I consider using in any case of failure, say bricking this device.
Thank you in advance.

Also I should mention that I'm not in US, and this phone is unlocked and I'm using gsm simcard and it works perfectly.

Boot into download mode to find the actual model number.

Hello, I actually have a similar example with my SM-930A. This phone is also factory refurbished and I as well had some suspicions. I RAN my IMEI# against imei.info.com to see if it was blacklisted. It gave me SM-G930F (SM-G930A). The problem is G930F is the international Exynos model and G930A is the USA Qualcomm model. They have different chipsets with different cores. I get mixed readings with different HW info apps including CPU-Z as if it's a hybrid between the two. The further I investigated, I found Verizon apps, IPhone apps and a suspicion that the firmware for ATT was flashed onto an International model but is using swapper and linker to hide it. I know it sounds crazy.

The hardware is NOT the same -- firmware is incompatible:
I don't think you can successfully flash the North American Qualcomm based firmware onto the Exynos hardware or vice-versa. At best it would give you an error, at worst it could brick the device. They are two completely different processors on different motherboards, and use different other hardware as well (power regulation chips, radio chips, etc).
What may have happened is that someone found a way to overwrite the model number and/or possibly the 3 character Samsung CSC (customer service code) code(s) in your refurbished phone. If the hardware says it is Qualcomm processor, then it probably is a North American hardware version of the S7.
Handy free hardware information tool for Samsung smartphones:
I use a free hardware information tool called "Phone Info *Samsung*" written by vndnguyen which is available on the Google Play store. It shows not only the phone model number, but the CSC codes, the date of manufacture, hardware, and all available sensor data. You might want to install it and see what that app finds. It has a few ads, but they are unobtrusive. Hint: disable notifications for it if you don't want to get "tips" from the author.
Discussion of hardware in North American models:
Note that the hardware for all the North American models is identical (with the exception of one Canadian carrier that uses the European/Asian version of the phone), and they all have the same Qualcomm processors and chipsets. All that differentiates them is the firmware and CSC code that is flashed onto them. The NA motherboards all have "SM-G930V/P/R4/A/T" printed on them. The cellular radios on the NA motherboard include the GSM radio bands used in North America and they also include a radio for the CDMA bands used in North America. IIRC, the GSM bands cover most but not all of the European/Asian GSM radio spectrum, so the phones should work outside North America, but possibly won't get quite as good reception as the European motherboard would get. One last comment about the NA version of the phone: If the phone has been carrier unlocked, it is possible to flash any of the various NA S7 carrier's firmware or the factory unlocked G930U firmware onto it. I have personally tested this. Flashing the G930U firmware onto a NA phone is a great way to get rid of all the carrier-installed "bloatware" apps, leaving only the Samsung interface and apps and the Android apps. However, flashing different firmware onto a phone does NOT carrier unlock the phone -- I found that out by trying it (the phone booted up, but when a non-original-carrier SIM was installed, it asked for and required a SIM carrier unlock code).
Discussion of hardware in European/Asian models:
The European/Asian version of the hardware is, as you mentioned, different than the North American version, and uses a Samsung manufactured Exynos processor and related chipset, and other hardware is different as well -- including the antennas, loudspeaker, and charging daughterboard. Interestingly, the European/Asian motherboards have "SM-G930FD SM-G930F/W8" printed on them, possibly indicating that the difference between the G930F and G930FD motherboards is, similarly to the NA motherboards, only the firmware and CSC code -- the actual hardware may be the same (other than the G930FD SIM tray which is capable of holding a 2nd SIM card OR a Micro-SD card). My understanding is that the European/Asian models do NOT have the capability to connect to CDMA networks -- and only will work on GSM networks. Again, IIRC, the GSM radio spectrum is slightly different in Europe/Asia and North America. However, I do know that the G930F and G930FD models will work in North America on the GSM networks, again, possibly with some reduced reception due to band differences. I have personally tested this by putting a US T-Mobile SIM into a G930FD phone I repaired and it worked well.
I have 3 questions for you folks in Europe or Asia that repair the G930F/G930FD phones:
1. Would you please clarify whether or not the motherboards for the SM-G930F and SM-G930FD are actually identical and only the firmware and CSC codes (and SIM tray) differentiate the two?
2. If a European/Asian phone has been carrier unlocked, can a different version of the European/Asian firmware be flashed onto it?
3. Are there factory unlocked versions of the firmware that have no carrier "bloatware" apps for the SM-G930F and SM-G930FD? If there are, please identify what they are, and supply links where to find them. I am not talking about custom builds -- but rather genuine Samsung firmware that is not carrier specific.
I hope this helps to clarify things a bit.

Sorry to be "that guy" but the US models are Qualcomm-based while all Canadian SM-G930W8 models are Exynos-based, so there is no "North American" model for the S7.
As far as I'm aware, booting an S7 into Download mode is the closest thing to a foolproof method for determining the true model of the motherboard in the phone, no matter what the label, Android, or any system info apps tell you.

Hello guys, following up your comments, here are the results of phone info *Samsung*

So just to make sure I understand your well, this phone has to be a Verizon variant even though at the back of the phone under glass is written SM-G930T?

Does the imei on the box or other labels match the imei when dialing *#06#?
Based on what is shown in download mode, the motherboard is from a Verizon s7 sm-g930v.
Bootloader from Samsung info screen begins with g930v too.

All firmware is the same. I have the "t" varient, now running the "a" varient for Oreo, but I always run the "u" varient cause less bloat. Someone made a detailed post earlier, might have been to long to read.

That's not true at all. I'm running the att Oreo beta on cricket that was branded sm-g930t. Download mode shows it's the "a" varient now. When running "u", you bet it also says "u", same with any firmware, if I flash "v", it'll say "v"

Sorry if my posts were not clear. I was referring to USA s7 models with Qualcomm processors. Canada and other parts of the world are using Exynos versions.
From the original post, Antutu reports the phone as being a sm-g930f and, as far as I know, there is no 930f for the USA: https://www.sammobile.com/devices/galaxy-s7/specs/SM-G930F/.
I wanted the OP to confirm the model # before flashing files (either for Qualcomm or Exynos) and a quick way to do that is in download mode.

Okay,
Thank you everyone for your contributions so far, I am actually getting the picture of what I have with me.
These are the information I have with this phone and from your input the finding so far:
The phone got SM-G930T at the back hence T-Mobile variant
Under Download mode it says this phone is Verizon variant
Under some settings like APN there are some bits of Verizon like Verizon APN - Hence Verizon variant
Under About Phone, the model number is SM-G930F ( I believe the one who flashed this phone they knew they wanted it to end up in international market, hence they found a way of making the model number looks like its an international model (SM-G930F)
The details of IMEI under imei under imei.info gives this result: G930F GALAXY S7 (SM-G930T) - Which gives more questions than answers.
What I believe right now is this is Qualcomm variant phone with Qualcomm chipset.
Now I really wanna know if which latest ROM I can flash to get the latest possible Android version in here! Say Android 7.1.1 or Android 8, etc. But something stable because this is now my main and only phone I got.
Thanks again for all your inputs and contributions.

If I were in your situation, I would flash the latest stock Verizon ROM since the model number is sm-g930v.
Before flashing, I recommend testing the phone to ensure it functions with your carrier. If it doesn't, I would contact the vendor.

If you think it's amerian latest is 7.0 with 8.0 coming next month. I'd recommend the "u" firmware, less bloat and less warning messages, like hitting airplane mode is one tap, not two cause a warning pops up

I'm not using Verizon line, I'm using Tigo line (Africa/Tanzania), so I'm not sure what Verizon ROM will do to this phone, whether will render this phone useless or because its now working then after flashing Verizon ROM it will continue working even though the SIM card is not Verizon SIM?

How do I test the phone to ensure the functionality with my carrier?
I think my situation is a bit complicated, there is no vendor, no warranty, I can do whatever I want with this phone, the only problem is whatever I do I have to be careful and sure that I won't brick this phone as it is my only phone right now.
All I want to do is to flash it with the latest android version

Put a sim card in the phone and make a call, receive a call, turn on wifi, turn on data, send a text, receive a text, take a picture, take a video, and insert an SD card.

Can someone suggest the right ROM which is latest and stable for my phone? Which is official but without any carrier bloatware?
The one I'm having right now got no carrier bloatware, only inactive verizon APN, and also got Samsung Apps which is okay with me (After start using S Health I found it a little bit interesting).

Go to sammobile, write your phone model and get the lastest firmware available, select the default one without bloat and don't forget to disable frp lock before flashing.

Differences between Australian, International and Dual Sim versions?

I'm mulling over upgrading to a Samsung S8+. The problem is that I want the Maple Gold version, but it's only available in the following forms:
* United States - Nope! Because I want the Exonys version because I want to root it.
* Australia - It's even got its own model number, different from all others, SM-G955FZDAXSA. I fear this might mean that the software and/or hardware is somehow inherently different from other International versions of the phone and I'll run into problems rooting it.
* A dual sim version - This can be hit or miss. Some dual sim versions can be rooted and flashed with the same custom roms as the non-dual sim version. Some require specific custom firmware in order to work properly or at all.
So what I want to know is whether or not the Australian version is different from other International (read: Non-U.S.) versions of the S8+ and whether or not the Dual Sim version can be rooted using the same methods and flashed with the same custom firmware as the single-sim version (though it might be too early to know this as of yet).

SM-G955FZDAXSA is just the product code that retailers use in Australia to maintain stocks etc, it's the SKU for the device.
SM-G955F is the actual model number, which is the international variant, which CAN be rooted. The 'XSA' part at the end is the CSC for Australia, all countries have a different one.
Here in Pakistan my S8 Plus is SM-G955FZKDPAK, the PAK at the end is obvious.
Dual SIM is called SM-G955FD, but the ROMs for 955F and 955FD are the same.
All the 955F models, whether Dual SIM or not have the Exynos 8895, unlocked bootloaders, can be rooted and you can use the custom ROMs available in the development section.
In short, all 955F models are the same (hardware wise). Nothing to worry about. Let me know if you have any other questions.

Great! Thanks so much! I'll order a Maple Gold S8+ sometime later today then!
Thank you murtaza02 for the information. I found a good set of specifications for the GN-955FD here:
http://www.phonemore.com/phone/samsung-galaxy-s8-plus-duos-sm-g955fd/3256
I found the device at a couple of retailers in NZ. I believe there may be errors in the specifications listed on their sites? Neither vendor lists the device as supporting LTE band 30, but I think they have just listed NZ bands. One vendor lists the chipset as Snapdragon. Is this even possible? The specifications at "phonemore" show it as available in blue, but I can't find one of these anywhere.
I wasn't aware that sim 2 only supports up to 2G (no 3G, 4G, or LTE on sim 2). Is this normal for dual sim phones?
there is information out regarding gluing a SIM card on top of an SD card, and using both. Would you happen to know, are people successful with this?
thanks!

Apologies for the late reply. Quote me next time so I get a notification for it!
The 955FD only comes in Exynos 8895 and the compatible bands are the same as on the single SIM 955F.
SIM 2 only supports 2G, unfortunately.
As for the gluing SIM on the SDCard, it is not only dangerous because your SIM tray could get jammed or stuck, it has also been patched by Samsung.
People did this on the dual SIM S7 edge, a software update was released that wouldn't allow 2 SIMs and a microSD card to be used at the same time.
So I doubt that it'll work on the S8/S8+.

Hi I have a galaxy S8 from the USA, but I live in the UK. It is a G950U with sprint firmware but unlocked.
I flashed the F950U1 firmware. Now WiFi hotspot is working.
But I can figure out how to setup Samsung pay since it defaults to US.
Is there anything I can do to get out work?

You can't flash any Exynos firmwares on a Snapdragon device. And there are no UK firmwares available for a 950U.
The best I can suggest is to (if possible) uninstall the Samsung Pay app and framework, and install the ones from APKMirror and see if that works then.

If you're in India, just download any OXM firmware, and flash it on your device WHILE AN ACTIVE INDIAN SIM CARD IS INSERTED.
You'll be on the Indian CSC and stuff like VoLTE and all should work fine.

Hi Murtaza,
Just wanted to check which is better to buy in Pakistan if I am not looking to root the device or install custom ROMs. I have the option to buy two types of Dual SIM variants of Samsung Galaxy S8 +. The first is the international version G955FD and the second is an Xfinity version 955U.
Which would run better in Pakistan? I am getting the US version cheaper and just wondering if there is a reason? As far as the benchmarks go both Exynos and Qualcomm versions are almost at par as per YouTube videos. So is there some other issue? Or is it just because the US versions are priced lower in the international market.
Secondly kindly confirm your comment about the second SIM being only 2G. As per my understanding, if I switch the data network, the other SIM becomes 4G as well. Or in the case of SO, I will have to physically shift the SIMs.
Would really appreciate some support on the above two queries.
Thank you.

Hi Sikander,
Choice is entirely yours, if you are not planning to root, then it doesn't really matter whether you get the G955FD or the G955U.
However, do not get fooled by the shady shopkeepers in Pakistan. The Xfinity G955U (or any G955U for that matter) is NOT Dual-SIM, it is only available in Single SIM, don't let anyone tell you otherwise.
The only Dual-SIM Exynos version of the S8+ is SM-G955FD.
As for which would run better in Pakistan, doesn't make a difference again. 2G/3G/4G will work on both of them. And yes, the 955U is cheaper because US variants are generally priced cheaper here due to lack of warranty and whatnot.
The second SIM is 2G only when SIM 1 is in 4G mode. Without physically changing SIMs, you can change SIM 2 to 4G, but then SIM 1 will be changed to 2G.
Also, I have to update. It's not 2G only, it's actually 3G/2G.
So if SIM 1 is in 2G/3G/4G mode, SIM 2 can be in 3G/2G or just 2G mode, depending on what you choose. Network modes can be changed around on the slots without physically removing the SIM slot and swapping them around so you don't have to worry about that.
Let me know if you have any more questions.

Hi Sikander,
Choice is entirely yours, if you are not planning to root, then it doesn't really matter whether you get the G955FD or the G955U.
However, do not get fooled by the shady shopkeepers in Pakistan. The Xfinity G955U (or any G955U for that matter) is NOT Dual-SIM, it is only available in Single SIM, don't let anyone tell you otherwise.
The only Dual-SIM Exynos version of the S8+ is SM-G955FD.

Dear Murtaza
I don't actually buy phones from local vendors anymore. One doesn't really know if they sell New or Reburbished models.
I generally buy from Homeshopping.com, and I have ordered at times from Daraz.pk.
The phone options I was looking at are as under.
https://homeshopping.pk/products/Samsung-Galaxy-S8-Plus-G955F-Price-in-Pakistan.html
https://homeshopping.pk/products/Samsung-Galaxy-S8-Plus-Orchid-Gray-Price-in-Pakistan.html
The first one is the Xfinity version and second is the FDD version. Both are with non official warranty, but getting it with warranty is around 12 K more. But I haven't had any issues with their devices so far.
Any idea about the 955FX version. My Cousin got one about a week back, but I am not sure which variant is that, as it is not even posted on GSM arena. Supposedly it is Dual SiM and an International variant. Still have to do a Abit of research on it.
I switched over to Chinese version a few months back. Very impressed with the phone in all aspects, but the only issue is that the Navigation is useless. The GPS keeps bouncing on GMaps. Its elephone S7. The other issue was Wi-Fi reception which is not that great. I think it was a radio issue, but not sure whether it was hardware or software. There is not much ROM development for the phone. Otherwise it would have been a great phone, with almost a vanilla ROM and hardware specs close to a flagship.
Anyway, just decided to go for a branded phone this time.
Waiting for the Black Friday deals to come up. Might buy the note 8 or S8 plus. Let's see.
Thanks once again.

955FX isn't a model number, 955X might be one but that's the demo / display unit used in stores and that has no cellular radio or SIM slot.
Do confirm the model number with him and then see.
Be cautious with HomeShopping though.

Will confirm the model number. I am pretty sure it's not a display version as he is using it. Will confirm once again.
Ok. Thanks. Will do on both counts. I have been buying stuff from Homeshopping since 6 years when I bought my first And if HTC Desire Z. Not had any complaints, but some people in my family have.
Take care.

I Purchases this phone in Kuwait. I travel around the world a lot and one function I've noticed not in this phones software is Wi-Fi calling. When I'm not traveling I'm on the USA on the T-Mobile network. Which software can I change the phone to to get Wi-Fi calling to work? Would Deutsch Telekom (T-mobile Germany) be the one to use for my dual SIM? Do they even make a dual sim for Germany? Please, any help and/ or direction would be awesome.

WiFi calling is carrier based. So it'll only work when you've got the SIM from your main carrier and the same carrier firmware to go with it.
Sent from my SM-G955F
I got a UK unlocked s8 at the moment and Wi-Fi calling works flawlessly with a o2 sim. So I think if you have a carrier unlocked phone, it's up to the carrier

New Samsung S7 trying to find what version it is.

Greetings All.
I have just got a refurbished samsung s7. I am trying to find out what the model of the phone is and am seeing a few conflicting things with the phone and the model numbers.
First off I am in New Zealand, I was expecting this to be the international version (the one thats common in nz) SM-G930F.
In the setting > about phone > Model number it is listed as a SM-G930F. This would make sense. However where it gets confusing is in oydn mode the phone model is listed as a SM-G930V and in CPU-Z app the phone is listed as a Verizon model and is using the Snapdragon 820 chip (not found on the F models).
I cant post links yet, but imgur with the id's below will have some screen shots of the phone and what im seeing.
Oydn Mode - /a/AxKfy
Other Screen shots of model numbers - /a/Mbo0Z
Thanks for any help
Common trick grey market sellers do, fake firmware to make it look like a 930F
Turn it off, then hold vol down + home + power until it boots into download mode. In there you should be able to get to phone information, and it will tell you the model info. Info in download mode can't be faked, and will be your real information.
Unfortunately so far from what you've said it's sounding like a faked US model.
Yep, probably the SM-G930V with firmware model number faked
As above, Download mode will tell you the real model
Very common trick to sell Snapdragon S7s as Exynos

Bought another S7 on Ebay. Seller listed as new G930U,warranty shows its G930V

Like the post says I got a G930V apparently after buying what i thought was a G930U
Its snapdragon for sure
Samsung Info App says G930U and fw is OFFICIAL PDA G930UUES9CSC2 AND CSC G930UOYM9CSC2
After factory reset it still shows as G930U
When i go to Samsung and try to register for warranty it shows as being SM-G930VZKAVZW
Did i get burnt?
What should i do? i can still ask for refund.

It's not a problem whoever you bought it off has installed G930U firmware which is unlocked and not branded with any network crap.
You can flash it back to G930V if you wish as the device was originally on the Verizon network.
It's a USA device, I'm assuming that's where you live. If not then yes it's a problem.

I appreciate this. Yes i am in the USA , i use a Tmobile mvno called Ultra Mobile. Did a LTE speed test and getting 100mbps down and 25mbps up.
The phone is really like brand new mint.
Here's the thing...i dont know if its because of the U firmware or what, but this phone is MUCH less responsive than my G930f. Just kindof drags all around.
I rooted, de-bloated what was left, changed to high performance mode, cleared dalvik, and its marginally better.
What surprised me is the antutu score of 154,000 which was same as my other G930f.
Could the snapdragon 820 be that much slower than the Exynos 8890?
its like i have to tap things twice for everything to get the apk to open or, like tap twice in browser to get the keyboard up!
Perplexed.

The G930V isn't Snap dragon its Exynos. Install "android phone info" from play store to make sure it is, then flash either the Verison firmware again or the U G930U, that should put it back to new and resolve any messing about with it before you bought it.

I already did install Samsung info, the first thing i did when i opened the phone. Its Snapdragon no question.
This phone is LAGGY! Like slower than my S5
Btw the guy from ebay now says that this is a G930V with U firmware flashed.
I dont know if its splitting hairs but i'm pretty sure im going to return it

galaxy s7 sprint G930P G930PVPSACSI2

I have tried and tried to root it but it always fails using odin. Could use some help.
G930P (sprint)
G930PVPSACSI2
Android Version 8.0.0
Samsung Experience 9.0
Build number R16NW.G930PVPSACSI2
Android Security Patch September 1, 2019
If someone can shoot me to a guide or working files for odin it would be greatly appreciated.
I've tried around 30 guides and 30 different odin twrp files and each one has failed when trying to use on odin.
https://forum.xda-developers.com/galaxy-s7/help/help-rooting-snapdragon-galaxy-s7-g930a-t3977565
You can't. The G930P is locked down, with no known method to get around it.
All USA models are snapdragon SoC and locked down, some have work arounds that involves using a leaked engineering bootloader from the factory, but not the G930P.
TWRP also isn't possible, all the files you were likely flashing are for the G930F, which is Exynos SoC and able to be bootloader unlocked.
I figured as much, just my luck. If I was looking for a good device to root which phone would you suggest or should I go with like iPhone 7? main purpose im using this for is like pokemon spoofing lol is an iPhone 7 hard to jailbreak>?
How about galaxy s9 sm g960u that's my main phone which I could root if it was possible but the downside was id need to find something to hide root from snapchat and other apps.
You'd have to check the forums for that model specifically, but a general rule of thumb is a US model Samsung phones with snapdragons are bootloader locked. You'll have better luck with other phones, or importing the Exynos model (although that comes with less network band support in the US)

it also should be said that the F model variants of the galaxy phones do not support CDMA which is what sprint and verizon uses. if you want to use T-Mob or AT&T with a euro phone, all good, theyre GSM which is what the F models are capable of working with solely. Do NOT get a euro spec phone if you want to use vzw or sprint

I'm not connecting it to service. Just trying to use it for wifi etc. So if I got a Galaxy S7 AT&T phone off amazon it would work? I don't really know how to get a euro phone when I live in USA and I normally buy everything from amazon. Is a iPhone 7 at&t jailbreakable?

Question S22 Ultra esim enable TGY csc

Hello all, new here! Never rooted a device, I'm very technical and confident but would like to ask the question as to why I'm looking to root or change CSC.
Currently my S22 ultra 512 is a Dual sim Hong Kong purchased device. TGY is the current CSC, basically I'd like to use the esim option and phones sold in Asia specifically China, Hong Kong & Macau at least I'm told have this disabled. My note20 ultra dual sim is the same. By changing csc/firmware can I enable this feature that other s22s have? Basically is there another s22 with identical hardware dual SIM and all that I can put on the phone that will enable this feature? I'd like call recordeding if possible as a phone feature rather app but it's not important. I'll attach screen shots of what versions I currently have. Sorry if I'm asking the wrong questions I'm technical but new to android rooting.. Willing to PayPal or donate to anyone who can assist me through the process. SM-S9080 TGY I know the Taiwan sold device is basically the same hardware but have not received a clear answer if esim is enabled, thinking no but figured I'd mention it. I'd also like to do the same to my Note20 Ultra. Thanks in advance

I think SM-S908E/DS is the same hardware

Hi Guys, someone can confirm if CSC TGY have esim activated on S22 ultra SM-S9080? o wich carrier could have it?
I'm having exactly the same issue... just tried out the HK and CN variant. Both don't an eSIM support.
However, I've also read somewhere that Samsung has "dropped" the eSim support in on of the recent Firmware versions, because the had too much trouble with that.
So the quesetion is: Is this a regional issue (e.g. TGY, etc.) or is is a "Version" issue (e.g. an earlier version still might have it)
Best!

hi i have a s9080 hk model and tried flashing the s908e/ds firmware through odin buy kept getting failed partition error
i want to share my experience with my note9, it was the N variant - South Korea, i had network issues in which case i had to root my phone and install a custom rom which had csc of my country and i worked great.
if you could do with a rooted phone follow this:
1. check if your phone is listed as rootable.
2. check if your phone has a custom rom:
if YES you could see or ask for what you need ( in the Rom's forum or the developer).
if NO wait and keep researching.
dont flash another region firmware even if its the "same phone" you might break the phone.
Okay, quick info: I've flashed all three regions (China, Hong Kong, Taiwan) on the SM-S9080 (current firmware versions june to Sep) and none of them have eSIM support.
This is really annoying - especially when all the offical samsung websites praise that the phone supports esim.
I'm personally pretty pissed off and the key reason is that I know that other users of the same phone in other regions of the world can use it and I'm not able to do this, because the programmers just want to make their lives easy and "silently" drop this feature from the firmware.
Something similar happened about 15 years back with a Sony device and since then I've never ever bought anything from Sony again (neither phone nor anything else). So the same is probably going to happen with Samsung.

When you flash a different CSC, I read that since basically the firmware reads your sim, grabs the CSC from that, that if you leave it out, on the boot up screen before you start the setup, you can hold Volume down, I believe or some button combo to skip through set up so you don't need a SIM to complete it.. then you have the actual firmwares original CSC and not the one that was read from your SIM card.. Cuz if not no matter what firm u are you flashing, if your SIM card is in there and you run set up it's going to go by that. The firms are supposedly all the same but what's changes is the CSC each time.. now overseas, United States, snapdragon vs Exyno it's a different story. They do have different firmware's...
But I do know that the phones are basically all universally the same all the same hardware but it's the firmware the software that does all the matter of difference... Including the bootloader for instance. We all have the same hardware but I can't unlock mine it's software there that can do it.. if I find the site up forward it for you.. have you gone into the service mode after enabling it? There's a bunch of crap you can do in there that has to do with antennas and SIM cards and ESIM stuff you might just need to enable something.

What I've (think to have) learned so far:
There are two different hardware combinations: (a) the snapdragon variant and (b) the Exynos combination. For each combination, there are differernt firmwares available
Each firmware (e.g. SN-S9080) is a special combination of modem-settings, software configuration, etc. that is geared to optimize the phone performance and battery consumption
For each firmware, you have then certain CSC variants, wihch then further add which apps are available, etc. (for example in the Taiwan variant, Google is available, while in the China Mainlaind variant it is not)
During the first-time installation process, you can choose the language of the phone (and maybe also the CSC), but you can't change the firmware
Therefore, my problem is this: I've tried all the CSCs which are available for m firmware (SN-S9080) but none has eSIM support. Now I want to flash a differetn firmware (e.g the SM-S908E firnware), but Odin currently doesn't let me flash this onto my phone.
Does anyone have a guidline of how to flash a SN90E firmware onto a phone which currently runs a SN-S9080 firmware?
Best!

During the first-time installation process, you can choose the language of the phone (and maybe also the CSC), but you can't change the firmware
Therefore, my problem is this: I've tried all the CSCs which are available for m firmware (SN-S9080) but none has eSIM support. Now I want to flash a differetn firmware (e.g the SM-S908E firnware), but Odin currently doesn't let me flash this onto my phone.
Does anyone have a guidline of how to flash a SN90E firmware onto a phone which currently runs a SN-S9080 firmware?
Best!

i think the chinese s9080 is locked down only because you cant flash other firmware like other models most secret codes like to change bands dont work and this model took agesto get one ui 5.0 update
Well, I can flash different CSC variants, e.g. the Taiwan or the HK variant (and these are not multi-CSC firmwares, but seperate files).
However, does anyone have an idea of how to flash e.g. the S908E firmware onto a phone that is currently running S9080?
I was able to flash all files of the S9080 variant (including BL - the boot loader), so that means that the phone is *not* locked, right?
I've tried to click the repartitioning option (because the S908E is bigger than the S9080), but that also didn't help.
Do I maybe really need need to "root" the phone first for flashing another firmware? This doesn't sound logicall, so I tried to avoid rooting so far ...
Any ideas or a link to a "how to" is warmly welcome ...

When you flash a different CSC, I read that since basically the firmware reads your sim, grabs the CSC from that, that if you leave it out, on the boot up screen before you start the setup, you can hold Volume down, I believe or some button combo to skip through set up so you don't need a SIM to complete it.. then you have the actual firmwares original CSC and not the one that was read from your SIM card.. Cuz if not no matter what firm u are you flashing, if your SIM card is in there and you run set up it's going to go by that. The firms are supposedly all the same but what's changes is the CSC each time.. now overseas, United States, snapdragon vs Exyno it's a different story. They do have different firmware's...
But I do know that the phones are basically all universally the same all the same hardware but it's the firmware the software that does all the matter of difference... Including the bootloader for instance. We all have the same hardware but I can't unlock mine it's software there that can do it.. if I find the site up forward it for you.. have you gone into the service mode after enabling it? There's a bunch of crap you can do in there that has to do with antennas and SIM cards and ESIM stuff you might just need to enable something.

with an without SIM card didn't make a dfference. The firmware files for 9080 are all single CSCs anyway.
So after more than five weeks of trying around, I finally have to say that it seems impossible to enable eSIM on a 9080 (i.e. the version bought in China).
I've tried so many things by now (the VN Rom, the Dr Ketan Rom, switching CSC to Hong Kong or Taiwan, etc.).
So my conclusion is this: You have two options
a) Don't buy a Samsung Galaxy phone at all
b) If you really want to by a Samsung, then buy on from a region where there are the least restrictions on your firmware in the first place.
Everything afterwards turns into frustration.
