Sorry for a potentially idiot question, but I have 2 phones in my household both as unlocked SM-F711U1. My software is "up to date" according to the software update within android and trying to manually update with the samsung smartswitch app via windows on both phones.
I am trying to get esim to work, which apparently should work with the updated software per this post https://www.xda-developers.com/samsung-galaxy-z-fold-3-flip-3-usa-esim-support/
Problem is, I don't have the F711U1UEU2DVEE version, it looks like I have the F711U1UES2CVD4. Do I just have to wait longer for the newer software to show up as available? I'd love to not have to manually flash these.
Thank you, I know it's a rookie question!

I had to flash mine to DVEE in order to see the SIM manager.
Thanks for the reply.
Is the DVEE update not coming to my particular type of flip3, or will it come later automatically if I'm patient?
Alternately (I'm not familiar with flashing modern phones) if I do have to flash is there a way to it that will preserve my apps and settings without it being wiped? And if I flashed does it still automatically update later? I've read a fair amount about flashing and even tried at one point on a different phone and had some problems...

Mine didn't fetch it automatically. OTA will eventually come, probably a newer one at July 1 security patch.

I manually did this for esim capability.

Hi. Sorry if I may have made any mistakes, I am new to this. I have a Verizon SM-F711U Flip 3 that I bought second-hand recently. I tried to use my existing AT&T sim card inside it but it rejected it with a "carrier change" message. I contacted Verizon and they told me the device was unlocked and fully paid off. Based on what happens it seems like the device isn't unlocked, but even after contacting them multiple times, they all say on their servers the device's IMEI is shown as unlocked.

I've flashed U1 firmware which removed the Verizon bootscreen and bloatware, and initially it seemed like it accepted the sim card considering it connected to 4G and allowed me to make calls and messages, but about 5 minutes later it displayed the same message saying "carrier change not supported" and disconnected from network. The service provider software version still shows VZW/VZW/VZW

Would flashing ATT U firmware fix this by any chance, or is there something else I could try?
If it said "you're not allowed to use another carrier at this time" and provided Verizon's 1-800 numbers, then that means the phone is still SIM locked to them
Thanks for the reply.

1. Yes, it will come via OTA eventually

2. If you want to manually install it, yes, you can do so without factory resetting

3. Yes, future OTAs should still work fine, if you manually flash

Interesting it dropped today.
If I want the most updated I have to manually grab it and esim was essential.
Now it's just security updates mostly.

@yygemmi770 , I saw you were having the same issue I was with the VZW not switching even after a flash. Did you ever figure out how to resolve this?

It is currently a verizon phone I'm trying to switch completely to Tmobile including their bloat. Here's what I have done.

1. I flashed a TMB version of the same build but its just booted as Verizon still. I got a message saying the sim was not for Verizon but everything worked.
2. The next thing I did was flash the latest U1 Tmobile version. I now got the no Verizon boot screen and no more sim message. However it still says vzw for the csc.

Were you able to figure this out? Thanks in advance.

EDIT: FYI I used the SamFW FRP tool to change the CSC and it worked perfectly.

I was able to get the CSC to change on stuck units by using Chimera Tool. This was the only successful way I was able to do it, as the normal flashing procedure would not work.

That is paid, no? I used the frp tool I mention and it worked like a charm no issues.
Yes that is a paid program, but I use it within our company. There are probably a number of different tools that can accomplish it now. Looks like sometime around May or April the solution was found and coded into these programs.

Oh that makes sense. I was happy that it worked. The other methods seemed very difficult.

    For those who aren't already aware, F711U is the model number of all of the US carrier versions of the Z Flip3. The F711U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. A "U to U" or "U1 to U1" flash does not require a factory reset, but changing from one firmware to the other will require one. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.

    Manual Odin flashing is designed for those who:

    - want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
    - want to flash U1 firmware to their U device
    - want to convert from U1 firmware to carrier U firmware
    - want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)

    For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via the various firmware download tools posted here on XDA like SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I have access to an internal Samsung firmware download tool that usually gets new versions before they hit the public firmware download tools, so that's where my files come from.

    This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware (or haven't done it in a long time), I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.

    Happy flashing!

    Notes:

    - DON'T QUOTE THE OP WHEN YOU REPLY, kthx

    - I have lots of threads just like this one for other Samsung flagships, if it interests you. For those who have already made use of my previous threads for a different device and are upgrading, welcome back :)

    - My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc

    - it's quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single flagship model, so I won't be uploading every single version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit the firmware download tools.

    - My naming method for folders on AFH is: build - bootloader - Android version
    So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.

    - HOME CSC file keeps data intact; using the other CSC will wipe data. Flashing USERDATA will also wipe data.

    - Since AT&T doesn't allow their firmware to be publicly available (for any of their devices), I'll try to always upload at least one USERDATA per bootloader increment for AT&T (and Cricket, if they get this model). I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.

    - For identifying USERDATAS, and to know what region/CSC to use in the firmware download tools if you're downloading yourself:

    AIO = Cricket (not available via firmware download tools)
    ATT = AT&T (not available via firmware download tools)
    BST = Boost Mobile
    CCT = Xfinity Mobile (Comcast)
    CHA = Spectrum Mobile (Charter)
    DSH = Dish Network
    TMB = T-Mobile
    TMK = Metro PCS
    USC = US Cellular
    VZW = Verizon (available via firmware download tools, but Manual Entry is required - Auto will not work)
    XAA = U1 firmware

    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.

    Can someone locate the thom browne fimware please?
    Well normally I would say that you can get it yourself from the various firmware download tools like SamFirm or Frija. But it looks like Samsung changed something over the weekend, as the current versions of the tools are failing to pull any firmware

    So I can grab it for you

    so if im flashing my verizon carrier lock (60 days lock) device to u1 it will unlock it?
    No, flashing firmware will never magically SIM unlock a device, no matter which model it is or what carrier it's from. The SIM lock resides much deeper than firmware
