If you're not doing a factory reset, then no, don't need to remove any accounts

As you said, if I'm flashing USERDATA that will wipe data. I typically associate "wipe data" with a factory reset so I guess my question is do I need to remove Google and Samsung accounts if I'm flashing USERDATA? Also, the ATT USERDATA in the OP should work with any firmware of the same Android version?

Thanks for all the help!

There's no need to flash USERDATA, if you're just updating software. So if you don't want to do a factory reset, I would just skip it

So with this you can flash SM-F926W to either U or U1 firmwares? I'm trying to flash Canadian version to either U1 XAA or U Verizon. It has been quite some time since I flashed but I just need to get into download mode and flash files from Frija correct? And pick CSC not Home CSC so the phone is wiped, no need to wipe or remove accounts beforehand correct?

I have a stupid question. My unlocked Fold 3 which is on Verizon still has yet to receive the OneUI 4.1.1 update. I'm still on version F926U1UEU1DVG7. I was curious if I can flash the XAA update F926U1UEU2DVI2 to get the OneUI 4.1.1 faster. If so, what settings do I need to select within Odin to not lose any data?

Flash HOME CSC, not the regular CSC.

But, there doesn't appear to be a changelog posted for that version yet. So I can't confirm if it's 4.1.1, unless someone else can verify and chime in

Do you happen to have the USERDATA for the current AT&T FIrmware (Which is now on Bootloader 2)? I tried the USERDATA that is linked in the first post but it failed in the patched ODIN.

Does your device have bootloader 2?

Yes, it has bootloader 2. I believe that is why the user data is failing when I try to flash it now. I had to send my phone into samsung under warranty for a failing wifi flex cable. The phone has been repaired but they also updated it to bootloader 2 before sending it back. I don't mind using it on unlocked firmware, but I usually flash ATT on my Samsung phones when possible.

I have a source who can get me firmware for any USA Samsung model, but he charges me for each one. So it wouldn't be free

Dear,
Should I go for SM-F926U or SM-F926U1 since I will not use it with AT&T or any USA network?

    For those who aren't already aware, F926U is the model number of all of the US carrier versions of the Z Fold3. The F926U1 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=327754
    U1 firmware: https://www.androidfilehost.com/?w=files&flid=327755

    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

    U1 Firmware XAA shouldn't have a USERDATA file on it, so you can just ignore that slot on ODIN.

    I guess what I'm asking is isn't there a way to just simply flash one of the US firmware's like XAA = U1 firmware or the CCT = Xfinity to enable the proper US frequency bands on a Physical dual sim international phone ?
    Click to expand...
    Click to collapse
    Nope. If you want US firmware, get a US phone

    I keep getting this error when trying to flash the U1 firmware on my Locked Verizon Z Fold 3. Am I doing something wrong?

    I do not want to lose my data so I'm using HOME_CSC. Will it go through if I just select CSC?

    Also, I have no Userdata file (I downloaded using Frija)

    Please help will be greatly appreciated.
