Before you proceed further, you must absolutely understand what you are doing, therefore, if the subject below comes as a total surprise for you, read more about it either on XDA or elsewhere.

You cannot flash muti-region firmware on your devices as the hardware is different. There is, however, a couple of options you can try to see if eSIM "becomes available" within the firmware that you have and this is a total speculation at this moment.

US phones, SM-F711U (network locked) and U1 (network unlocked) come with a single IMEI of a physical SIM slot. Traces of eSIM are nowhere to be found within the phone's settings. As compared to multi-region phone, SM-F711B, that comes with 2 IMEIs printed on the box, which can also be seen in the phone's Settings->About the phone.

DISCLAIMER: I am not responsible for any possible damage to your phone as a result of the actions described below. Do it at your own risk and peril.

I found this external link that is applicable for OXM (multi-region) Samsung devices that are distributed across Europe and Latin America. It would be interesting to know what options will you get on your phone. I do not know the specifics of which IMEI to try, therefore, it is more on trial-and-error side of the matter:

https://www.droidwin.com/change-csc-codes-samsung/#What_is_OXM_Multi-CSC_Firmware

Alternatively, you can try entering hidden CSC menu if you do the following steps. This used to work in older Samsung phones (Dual SIM Galaxy S9 for example, not sure if it still works in the latest models)

1. Download Google Phone application from Play Market

2. After installation, dial the following combination in Google Phone:

*#*#27262826#*#*

3. See what the available options are and change CSC.

A friend of mine had a Samsung Latin America SM-F711B device brought in the US, however, eSIM IMEI was grayed out and SIM Card Manager menu option in Settings->Connections was not available to scan QR code or enter the plan details manually. Samsung Latin America said that certain features of the device may change depending on the region. Not sure if that was referring to which region the devices were manufactured for or the physical location of the device. Samsung US only said that eSIM of that device was not compatible and therefore as grayed out. The details of incompatibility were left ambiguous. At the time I knew about it to try the steps above, the device was no longer available.

Please, post screenshots of available options when you enter the CSC menu. Perhaps, what you find out may not meet your expectation. Remember, entering the menu does not do anything to your phone, however, applying the choice through installation will. Thanks.
[Samsung Galaxy Z Flip 3] shaan_x:
Thank you for the feedback back and advice, i tried to enter secret CSC menu by following the instruction but nothing happens.

Alright contacted multiple times to Samsung but have not got any positive answer regarding the esim, only that there is a software update coming which will enable the esim.

Which is interesting as 1 IMEI number is currently shown on my phone too, sadly i found out that esim was not available on my model after i got the phone and converting my sim to esim.

Really appreciate your response and provided information.

If there is anything that can be done please let me know.

Current CSC on my device is XAA.
[Samsung Galaxy Z Flip 3] job42:
I have had a talk with AT&T Support and they also confirmed that the only eSIM support they currently provide is for iPhones and Samsung Galaxy watches. I doubt that eSIM specification on the Samsung watch is different from the phone. I also have doubts that eSIM specification for Samsung OXM (multi-region) phone is different from Samsung XAA (single region US), however, this is just my speculations as there is no eSIM specification and implementation details available on Samsung website to compare between the regions. AT&T also confirmed that the support for eSIM in Samsung phones will be available "soon". There were no specifics about the definition of "soon" from AT&T.

Bottom line: the more we, as users, start pushing Samsung Support and local carriers with eSIM availability on Samsung devices, the better. I know that currently, there is a test firmware with eSIM support available for Samsung Galaxy S21 family. Hopefully, the update with eSIM support will come to Galaxy Z family sooner than we expect.

why my f771 u does not go into download mode? it is booting into recovery but when I select reboot to bootloader nothing happens and go to normal startup tried to adb as well.

any suggestions?
[Samsung Galaxy Z Flip 3] job42:
The only way that worked for me to enter the Download mode was through the use of Odin software (aka Odin Mode). More info here (your case is #3 in the article). It also has adb commands to enter the mode, but I only tried Odin Mode.

https://www.thecustomdroid.com/samsung-galaxy-download-odin-mode-guide/

1. Power off the phone.

2. Launch Odin software (make sure you use the latest release) on your PC and connect one end of USB-C cable to your PC. Keep the phone powered off and do not connect USB-C cable to your phone yet.

3. Hold simultaneously Vol Up + Vol Down buttons on your phone (being powered off) and connect USB-C cable to your phone. In a couple of seconds, you should see a WARNING message at which point you can release volume buttons. Follow on screen instructions to enter the Download mode.
[Samsung Galaxy Z Flip 3] auto_art:
thanks mate that worked.
[Samsung Galaxy Z Flip 3] RMSfan:
I downloaded the U1 firmware from Frija, successfully installed it on my Z Flip3 using Odin, and when I booted it up, it ended up being the "Thom Browne" edition firmware (to my horror) with custom Thom Browne theming. It looks like the download links in the OP are also the "Thom Browne" firmware.

Where can I download and install the vanilla Samsung unlocked U1 firmware?

Edit: Found the vanilla firmware here: https://samfw.com/firmware/SM-F711U1/XAA/F711U1UES2AUJ7

The OP should probably warn readers that the download links he provided are for the Thom Browne customized firmware.

Latest Android 12 beta for SM-F711U1 (XAA), unlocked DOES NOT have eSIM feature after flashing.

Edit: this thing is like S21... can't change CSC at all. To hoot, I flashed U1 XAA (with XAC first) and now I can't go back to U TMB, it flashes fine but just doesn't take.
[Samsung Galaxy Z Flip 3] Lasetguy216:
So idk what I'm doing wrong here, tried 4 different image sets and still get FAIL model mismatch .

I have a sm-f711u with 2 imei's on the box, trying to flash U1 nothing mismatch, tried just U nothing FAIL, drivers installed, com3 added, download mode & usb debugging enabled... don't have a OEM unlock option.
[Samsung Galaxy Z Flip 3] K3n H1mur4:
Weirdly enough, Samsung just released a new firmware this evening (I've been checking for updates more than daily, and it wasn't available about 10 hours ago). No Android 12, no December security patch.
[Samsung Galaxy Z Flip 3] job42:
This thread is for SM-F711U and U1 variants (US version). Some may get confused with SM-F711B variant, which is non-US version and is not relevant here.
[Samsung Galaxy Z Flip 3] yygemmi770:
Is anyone else having problems having the phone prompt a restart with sim after U1 flash?
[Samsung Galaxy Z Flip 3] yygemmi770:
Ok so after doing a clean flash to U1, the csc still reads vzw/vzw/vzw. Trying to get it to TMB by putting in sim card and wait for restart then flash U package with user data. Any tips as to why this is not flashing XAA using U1?
[Samsung Galaxy Z Flip 3] job42:
SM-F711U1, Samsung One UI 4.0 beta 3, I am having an issue with Internet speeds when using mobile data: about 1MB/sec (3G-like), where it shows LTE+ (4G+) and should be about 10MB/sec. Anyone else?

UPDATE: Can't stand the slow speeds using mobile data, downgrading to F711U1UES2AUJ7 (Android 11). After the downgrade, mobile data speeds are back to the expected values (about 10MB/sec) for LTE+.

How to enter download mode:

1. Power off your phone (Vol Down + Power -> Power Off)

2. While being completely off, hold both Vol Up + Vol Down buttons simultaneously and connect your phone to your pc with USB cable

3. Press Vol Up when prompted to enter download mode.

ATTENTION Frija users: be careful using "Auto" mode for XAA as it automatically downloads CSC OYZ instead of required OYM

Yes this is very disappointing news i own F711U1 model flip 3

Have been contacting Samsung none stop since i got the phone almost 3 months now.

At first they said esim enabled update will be done shortly and now the replies has changed they are looking into it and if i dont get esim update this phone will be my last Samsung phone.
[Samsung Galaxy Z Flip 3] job42:
Unless the situation improves, the only way to go in the future would be with non-US version, however, there are limitations:

1. eSIM will not function as US carriers are deliberately blocking eSIM IMEIs on their network and provide the "support" only for outdated phones (example: Note 20 got eSIM support in mid 2021). All it takes to support eSIM is to allow eSIM IMEI to register within the network.

2. 5G will not be available or very limited due to hw differences.

Non-US versions (Latin America, but still OXM multiregion) can be bought on Ebay from reputable US sellers, brand new, unopened, with security seals, UPS or FedEx delivery.
[Samsung Galaxy Z Flip 3] d0x360:
That's not exactly true...

The Note 10+ and the z Flip3 can be rooted or could be and probably more if not all models but there's a catch and yes I'm talking about the USA snapdragon version.

First it has to be a carrier unlocked version so it has to be bought from Samsung. Second it has to be rooted before you put a sim card for any carrier in and lastly there's the catch... It requires access to a program made by Samsung that somehow has never leaked but that website that charges like $150 to do it to your phone has it so I'm assuming it's a Samsung employee..

It's truly unfortunate and we can all give a giant thanks to Verizon for the battle against root/custom roms. They pushed the companies making phones really hard to get rid of the ability to do it and they basically complied.

Shame really.
[Samsung Galaxy Z Flip 3] shaan_x:
Is there any update on esim functionality for F711U1 with new software or has anyone heard of anything, i have been waiting 3 months for this and as per samsung this week update is happening.
[Samsung Galaxy Z Flip 3] iBowToAndroid:
I already know all about the paid services for bootloader unlocking.

Yes, the N10+ (and lots of other models) can be BL unlocked (and also therefore rooted) - but only if they're running firmware that's about a year old, at this point.

There is no method for the US Flip 3, regardless of which version it's running
[Samsung Galaxy Z Flip 3] job42:
A bit of night reading on the subject of BL unlocking on Samsung devices:

https://www.thecustomdroid.com/samsung-galaxy-bootloader-unlock-guide/

Excerpt:

Samsung Galaxy devices that are sold in the USA with a Qualcomm Snapdragon SoC come with non-unlockable bootloaders (officially). And so, the OEM unlocking option does not exist on such devices.

UPDATE: Therefore, I also do not believe that even paid services can do anything on the SM-F711U and U1 models (US variants).
[Samsung Galaxy Z Flip 3] Haz3:
It is actually possible I have a note 20 ultra from Google fi that is a u1 variant that is unlocked and rooted it cost me $125. The downside is is it's something to do with a cryptographic key that's tied to the phone specifically and the program above that the person was referring to was something similar to TeamViewer where somebody connects to your phone remotely and flashes what I believe is an engineering rom through Odin that allows for unlock but it breaks knox. And also it's not possible to update past like March 2020 security patch I believe because they updated the bootloader and if you flash it it will re-lock your bootloader and you're screwed.
[Samsung Galaxy Z Flip 3] job42:
you s

You said it: "engineering rom" that probably leaked somehow and being used in closed circles.

Were you able to install a custom bootloader and flash some alternative roms on your Note 20 Ultra? The whole purpose of unlocking the BL would be exactly that.

Note: we are getting sidetracked here - no such services have been confirmed for SM-F711U or U1 variants.
[Samsung Galaxy Z Flip 3] Haz3:
I used the word "engineering ROM" for lack of better term nowhere in the build prop or anywhere else does it say engineering. You won because most people weren't willing to pay to get their bootloader unlocked. I did however have twrp and later on Seahawk and orange fox custom recovery projects. The website and the entire unlocking process is ran by an individual that's well known within XDA and Samsung circles. It has nothing to do with a leak and everything to do with an employee that works at Samsung. As I said in my other post it has to do with the cryptographic key similar to how OnePlus phones on T-Mobile require a unlock key. But I digress as you said we're taking this thread off course just wanted to add my two cents I've seen a lot of misinformation and miscommunication.
[Samsung Galaxy Z Flip 3] job42:
Thank you for the clarification as this is still valuable information and might be useful for some in the future.
[Samsung Galaxy Z Flip 3] iBowToAndroid:
1. What is flashed is an "engineering token", which allows for OEM unlock and therefore flashing of custom binaries (like recovery, boot, etc). The token itself does not trip Knox, but it's the flashing of a custom binary that does it.

2. I think you meant to say that you can't update beyond March *2021*, which is technically correct if you're talking about full stock firmware. There are updated stock firmware packages out there available for flashing that have been modified to retain an old "safe" bootloader and still allow you to be on a newer version
[Samsung Galaxy Z Flip 3] Haz3:
1. That's the phrase I wanted to use but was unsure as I'd only seen a few conversations about the process.

2. Yes March 21( and to all your points really) I was attempting to replies to the others earlier but also was at work getting ready to leave so didn't have as much time as I need to convey what I need/should have. Apologies all
[Samsung Galaxy Z Flip 3] shaan_x:
I have just received android 12 update for F711U1 and sadly no esim functionality still.

Earlier this week when i contacted Samsung they said it will be enabled with this week update.

Has anyone had any luck on esim for F711U1?
[Samsung Galaxy Z Flip 3] job42:
UPDATE #1 (Jan 5, 6:57pm CT):

Just clicked on "Software Update" on my SM-F711U1 and it started to download.

UPDATE #2 (Jan 5, 7:11pm CT):

no eSIM feature after the update on my SM-F711U1 as confirmed by a single IMEI after dialing *#06#. eSIM, if enabled, should have showed IMEI #1 (SIM) and IMEI #2 (eSIM).

UPDATE #3 (Jan 5, 7:15pm CT)

Frija is showing new Android 12 download available for Model: SM-F711U1, CSC: XAA . You can now download it and flash it through Odin too.

New version: F711U1UES2BUL7 / F711U1OYM2BUL7 / F711U1UES2BUL7

Now, regarding your eSIM issue, you can start talking to Samsung Support through Members app, escalate to Samsung Care Pro representative and ask the following or similar (I did it this very morning):

1. In Samsung Shop app, specs tab for the phone SM-F711U1, indicate "SIM 1 + embedded SIM" in SIM Slot Type parameter. Nowhere in specs it mentions about eSIM being disabled or requiring an update to enable it.

2. I have a product SM-F711U1 that only has one SIM 1 IMEI, missing eSIM IMEI.

This is product defect and it needs to be addressed asap.

Do not listen to what they have to say at this point. Just confront them to acknowledge #1 and #2 above, which is true.

Depending on who you get and time at hand, the number of available options is as follows:

a) Samsung will start talking about a mysterious "update" that supposedly will enable eSIM in the future. We all know where it goes from there.

b) Samsung will try to open a reference ticket (begins with 1) to "report" an issue. Nobody will do anything, really.

c) Samsung will try to open a repair request ticket (begins with 2) to start your device "repair". You will receive a text message later from Samsung with a URL, and if you fill in the details, they will initiate your device being shipped to Samsung for repairs. There is nothing to repair.

d) You can initiate a full refund regardless of depreciation. A faulty product, that gets advertised and charged as one thing but being sold as not official specs compliant product smells like a lawsuit. Any lawyers here to confirm?

Bottom line: Samsung Care Pro professionally does not care and will not get eSIM enabled until operators "allow". What you do with your SM-F711U1 at this point is entirely up to you. So far, only Note 20 Ultra (US variant) got eSIM support for all I know. Anyone else with the Samsung US phone and eSIM support, please, come forth and share some details.
[Samsung Galaxy Z Flip 3] iBowToAndroid:
AT&T USERDATA for Android 12 has been uploaded to the link in the OP - build UL7. Other carriers are getting this build also so the rest of the files will be readily available in lots of other places if needed
[Samsung Galaxy Z Flip 3] mawin:
I bought a Verizon flip 3. The phone has a sticker on the back with IMEI & IMEI 2 (!).

Of course it is not enabled. It auto updated to Android 12 but still esim not enabled.
[Samsung Galaxy Z Flip 3] job42:
Let's organize a massive call campaign to Samsung Support about eSIM being disabled on fw level as follows:

1. Flip3 official Samsung specs indicate "SIM 1 + embedded SIM" without any restrictions imposed (see screenshot attached).

2. Where is the eSIM IMEI on the phone? Dismiss any attempt from Samsung to mention an update or a carrier dependency as there is no official Samsung statement regarding the matter.

3. Escalate to Samsung Management, ask for the ticket number.

If we get 100+ requests, it will get some attention.
[Samsung Galaxy Z Flip 3] iBowToAndroid:
Let's not hijack my thread since its purpose is not eSIM.

Thanks.
[Samsung Galaxy Z Flip 3] blkghost22:
Im sorry to ask but can you find the thom browne android 12 one ui 4? Please.
[Samsung Galaxy Z Flip 3] iBowToAndroid:
You can get it yourself via Frija and the other similar firmware download tools, by manually typing in the correct fields
[Samsung Galaxy Z Flip 3] blkghost22:
for the love of my life, I cant find it on sammobile or frija. I have not clue what model or the manual inputs i am trying to look for
[Samsung Galaxy Z Flip 3] iBowToAndroid:
SamMobile doesn't have it. That's why I specifically mentioned "Frija and the other similar firmware download tools". Computer tools, not websites

PDA: F711U1TBS2BUL7

CSC: F711U1OYZ2BUL7

Phone: F711U1TBS2BUL7
[Samsung Galaxy Z Flip 3] blkghost22:
Thank you soooo much, may i ask (in case for later in the future) how do i know what oda csc and phone to input. Your knowledge is greatly appreciated
[Samsung Galaxy Z Flip 3] iBowToAndroid:
Frija and the other similar firmware download tools always only pull whatever the very latest version is. But as long as you know the correct CSC and other versions from at least 1 valid release (even if it's an older one), the tool will automatically pull whatever the latest version is. You just have to always use Manual entry because if you do Auto, you'll get the normal U1 firmware with no branding
[Samsung Galaxy Z Flip 3] blkghost22:
Thank you. I kinda had an idea but i didnt even know it was the tbs the firmware (F711U1TBS2BUL7) smh.
[Samsung Galaxy Z Flip 3] iBowToAndroid:
Yep, regular U1 is UEU or UES, and Thom Browne is TBU or TBS
[Samsung Galaxy Z Flip 3] apatcas:
T-mobile is really taking their time with this release. they are literally last.

Next thing we'll see Twitter messages about the "brutal expectations" customers have of receiving software updates.
[Samsung Galaxy Z Flip 3] iBowToAndroid:
So flash it manually...? That's literally the entire point of this thread
[Samsung Galaxy Z Flip 3] apatcas:
If I flash the unlocked version of the software than Samsung Messages doesn't have RCS support. And I ain't sharing every text message with Google just so I can use Google Messages.

I don't know if AT&T uses Samsung Messages or Google Messages.

Would I be able to just put the AT&T User_DATA in the CSC part of Odin and flash?
[Samsung Galaxy Z Flip 3] iBowToAndroid:
Yeah you definitely haven't read the OP.

There is no such thing as "AT&T firmware" or any "(insert carrier here)" firmware. You can flash any F711U firmware and be perfectly fine
[Samsung Galaxy Z Flip 3] apatcas:
I think you didn't read why I want the carrier bloat. I need Samsung Messages to have RCS enabled.

So my question again is... If I use the AT&T user data in the CSC part of Odin, will that give me all the AT&T bloatware?
[Samsung Galaxy Z Flip 3] iBowToAndroid:
Why would you put USERDATA in the CSC field of Odin....?

CSC goes in CSC. USERDATA goes in USERDATA
[Samsung Galaxy Z Flip 3] apatcas:
Sorry, that's what I meant. Also, I just flashed AT&T userdata and I can confirm that mixing U1 firmware with U Userdata does not work. No AT&T apps were installed.
[Samsung Galaxy Z Flip 3] iBowToAndroid:
Well of course that's not going to work.

But why do you want AT&T bloatware when you have a T-Mobile device?
[Samsung Galaxy Z Flip 3] apatcas:
Because I do want android 12 and T-mobile is taking their sweet time with it.

But I also do want RCS in Samsung Messages and that is apparently carrier phone specific.

Do you know of a way to install OneUI 4 from AT&T on a U1 firmware?
[Samsung Galaxy Z Flip 3] iBowToAndroid:
U1? You previously said that RCS *doesn't* work on U1 firmware.

Nothing you're saying is making any sense.

But you can download Android 12 F711U firmware and flash it, sans USERDATA
[Samsung Galaxy Z Flip 3] apatcas:
What csc should I use?
[Samsung Galaxy Z Flip 3] iBowToAndroid:
It doesn't matter
[Samsung Galaxy Z Flip 3] apatcas:
So If I download the Verizon Android 12 update and use AT&T userdata, will my phone look like a branded AT&T phone?
[Samsung Galaxy Z Flip 3] iBowToAndroid:
I said "sans USERDATA". Do you know what the word "sans" means?
[Samsung Galaxy Z Flip 3] apatcas:
Sorry. That was definitely on me not reading all of your reply. Do I use their CSC?
[Samsung Galaxy Z Flip 3] iHeartslutsz:

Yes
[Samsung Galaxy Z Flip 3] iHeartslutsz:

[Samsung Galaxy Z Flip 3] iBowToAndroid:
1. Download the firmware

3. Flash with Odin
[Samsung Galaxy Z Flip 3] iHeartslutsz:
Okay , so I get to part where it says android recovery, i selected reboot to bootloader and it doesn’t give me the blue download screen or is download mode the part that says android recovery? Sorry for all the questions it’s my first Android.
[Samsung Galaxy Z Flip 3] iBowToAndroid:
1. You need to have the Samsung drivers installed first

2. You need to already be holding the volume buttons when you plug it in. Then let go when you see Warning. Then press Volume Up
[Samsung Galaxy Z Flip 3] iHeartslutsz:
Oh okay . I figured it out but now im having trouble with the firmware on my order page from Samsung it just had sm-f711u but in my phone settings it has sm-f711u1 but the firmware i downlaoded said there was a write error when i loaded everything in odin and pressed start.
[Samsung Galaxy Z Flip 3] iBowToAndroid:
1. What's your phone's current version?

2. Which exact version did you download?
