(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!

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

Flashed a physical T-Mobile F711U to a F711U1 XAA firmware using Odin(Can't stand the bright pink boot up animations).

Flash worked perfectly. But, when I tried to test doing an update from Google settings it failed every time with "Registration Failed". I flashed the device back to the T-Mobile F711U firmware and was able to update without issue.

Not sure if you ran into this issue, but it's worth noting you might not be able to update the phone if the carriers are checking the Firmware.

Edit: Also forgot to mention, had to use the patched Odin due to the Firmware Model mismatch. Phone does work properly though.

What do you mean by "doing an update from Google settings"?

What type of update? What "Google settings" exactly?

From "Settings" App > "Software Update" > "Download and Install" and pressing the "Download and Installing.

I get "Connecting to server" and then immediately "Registration Failed" I've attempted over Wi-Fi and with that option toggled off.

This could also be the phone is new and T-Mobile doesn't have the F711U1 XAA firmware at their carrier level, but the registration failed annoys me. On F711U (official T-Mobile firmware) I simply get a notification that the device is up to date.

Which F711U1 version did you flash?

Which F711U1 version did you flash?

I flashed my phone using the F711U1OYM1AUG7 (F711U1 XAA) firmware from sammobile.

I flashed it back to the T-Mobile firmware, (F711UOYN1AUGB (F711U TMB) and the issue went away.

I did flash it again to the XAA to confirm the problem this evening. Never retained data during the process. Factory reset and removed my account information (Google and Samsung) before updating the firmware each time.

I've done this on a few phones in the past. If I'm making a blunder in the process causing this then I'm truly sorry for wasting anyone's time.

Well UG7 is the latest that's available. So yes, I would expect you to get an error.

Once an update is available, if the phone is still giving the same error, then you can worry about it

Or want too work with me on One. Sorry too spam or thread. But if u are familiar with how rom building, and flashing was with any other recent samsung model/Xfinity/bootloader unlock. It would be highly appreciated too know your experience.

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

1. Thom Browne *is* U1 firmware

2. USERDATA belongs to U firmware, not U1. So I have absolutely no idea. You'll have to try it and see what happens

Have successfully flashed F711U1 to F711W. Everything working fine. Used Odin 3.14, CSC_OMC_OYV, and working on Telus with all available features working.

Please note that AFTER the flash, you will be prompted to reset the device to stock. Reason being is that it needs to install the appropriate CSC linked to the inserted SIM card.

Can anyone confirm if cross flashing different build firmwares that it will unlock the unlock bootloader option?

Currently on carrier firmware for TMobile and I'm wondering if this is possible or if the u1 firmware has the unlock bootloader option available

    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
