Well of course that's not going to work.

But why do you want AT&T bloatware when you have a T-Mobile device?
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?

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

1. Download the firmware
2. Put the phone in Download mode
3. Flash with Odin
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.

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

1. What's your phone's current version?
2. Which exact version did you download?

    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.

    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?
    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.

    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
    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
    1
    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
    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

    Thank you. I kinda had an idea but i didnt even know it was the tbs the firmware (F711U1TBS2BUL7) smh.
    Yep, regular U1 is UEU or UES, and Thom Browne is TBU or TBS

    (WIP, files are currently processing and uploading)

    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!

    U firmware: https://www.androidfilehost.com/?w=files&flid=327752
    U1 firmware: https://www.androidfilehost.com/?w=files&flid=327753

    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

    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

    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.

    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
    1
    So If I download the Verizon Android 12 update and use AT&T userdata, will my phone look like a branded AT&T phone?
    I said "sans USERDATA". Do you know what the word "sans" means?
