Thanks.
So far so good on my ATT Locked S9+

Thank you so much. This set my G965U1 back to unlocked userdata and all my Att bloatware is gone. If you have a G965U1 device this firmware will work to set you back to original state when recieved from samsung. I used Home csc and no userdata file and it removed the att userdata I had been using.

I will be sharing this to help other get back to their original unlocked state. Thank you to OP.

Sure and no problem.

Thanks and 5 stars!
EDIT: FYI: Flashed on a Verizon (VZW) ARF4 S9+. Came back up as unbranded as expected! T-Mobile SIM in device and device asked to reboot once it finished the initial boot up (not set up). When it did, I completetd the setup process. Once I finsihed I was able to place WiFi calls and no effin bloat!!! It does seem to be VoLTE.

No problem :good:

Will applying this firmware unlock a locked AT&T S9 plus phone? Ultimately I would like have a TMobile branded phone or at least be able to use a TMobile SIM on it.
Thanks in advance

I found the answer to my previous question and the short answer seems to be no.

So I flashed my SM-G965U1 (Unlocked S9+) to the U firmware. I'm currently on G965USQU3ZRLG (Pie Beta 4) and I can't flash it back to U1/XAA "G965U1UEU3ARK5" in Odin. What am I missing?
<ID:0/006> Odin engine v(ID:3.1301)..
<ID:0/006> File analysis..
<ID:0/006> Total Binary size: 6534 M
<ID:0/006> SetupConnection..
<ID:0/006> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)

I downloaded odin, I have it installed. currently DLing, the U1 firmware you posted to put on my U. Anyone able to give me a crash course in how to load it on to the phone with odin?

G970U and G970U1 Firmware Links Here

For those who don't know, G970U is the model number of all of the US carrier versions of the Galaxy S10e. The G970U1 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. 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 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 pay for a subscription to a site that gets the official releases (usually) before they hit SamFirm/Frija, so that's where my files come from. However, I don't have unlimited bandwidth on the site, and it's also quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Sx and Note x 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 SamFirm/Frija.
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, 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=290639
U1 firmware: https://www.androidfilehost.com/?w=files&flid=290640
(Quebec tends to be the fastest download mirror, if it gives you that option)
Notes:
- I compress extra small for space and bandwith savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- I remove the .md5 from each file solely for faster flashing (Odin won't check the file integrity without it). Rest assured, the files are perfectly fine and safe - Odin has a million safechecks built in.
- My naming method for folders 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. Any zips with "wipe" in the title do not have a HOME CSC included.
NOTE: With initial release, HOME CSC was not included by default, so I created it myself. Should flash fine, but until noted by someone in the thread, it has not been tested.
- I have identical threads for the S10 and S10+ as well
- 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 SamFirm/Frija:
AIO = Cricket (not available via SamFirm/Frija)
ATT = AT&T (not available via SamFirm/Frija)
BST = Boost Mobile
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
SPR = Sprint
TMB = T-Mobile
TMK = Metro PCS
USC = US Cellular
VZW = Verizon (available via SamFirm/Frija, but Manual Entry is required - Auto will not work)
XAA = U1 firmware
- the correct procedure for switching from one carrier's firmware to another is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want

Just a quick question will you be hosting FW for models G973U, G973U1, G975U, G975U1? Don't know if XDA will have separate forums for the s10e and s10+ models. Supposedly there will be a 5G S10+ coming during Mid 2019 which would have a separate FW section I assume.

Read the OP

Nice plan! Kudos

Build SBA added.
SPR is the only USERDATA for this build so far - not sure if it will stay a Sprint-exclusive release, or be more widely pushed out. But like with any other build, it can be flashed to any S10e, regardless of which carrier it originally came from.
EDIT: Xfinity and Verizon USERDATAs added

I have the tmobile variant. Trying to flash and keeps failing for some reason. Trying to flash the U1 . Came with G970USQU1ASAT

As of the moment of posting, these cannot yet be obtained from SamFirm, and are not yet on SamMobile, but I thought some of you might like to get early access
I have no idea if existing patched Odin can be used to flash them, since I don't have a device to try it on. Maybe one of the blog sites can give it a try for us, on one of their review units. But at minimum, devs can peek into the partitions if they want, or casual users can keep the files on hand for converting firmware, once they get their device.
The large files will be your 4 part firmware and then grab your desired USERDATA as well. I'll continue to add more versions and more USERDATAs over time.
Happy flashing!

- I have identical threads for the S10 and S10+ as well
- You can get USERDATAs from SamFirm for everything but AT&T - those files will never be on SamFirm. So in addition to the 5 piece firmware, I'll try to always upload one USERDATA per bootloader increment for AT&T
- For USERDATAS (all the others are self explanatory):
ACG = C-Spire
AIO = Cricket
LRA = Bluegrass Cellular
CCT = Xfinity Mobile (Comcast)
CHA - Spectrum Mobile (Charter)
TMK = Metro PCS

There might not be "codes" per se, but there's always a specific error that either shows up in Odin, or on the phone itself

Yeah, I remember on earlier phones there were errors showing. I didn't see anything except failed only on Odin. I'll try again later. I tried both the patched by raymond and regular Odin.

The only Odin that might work is the 3.13 patched (3B). But as stated in the OP, I have no idea if that Odin will work, or if a new one is needed.
If Odin fails, then we need to know on which step it fails, and what the message is. Probably best to just post a picture of it, or paste the log

Just to be clear, nobody has been able to flash U1 firmware to a U s10 device?
Considering ordering an s10e, but hoped that I could flash the U1 firmware to pass the provisioning check for tethering.

@iBowToAndroid
By any chance is there an AT&T userdata for the new SBA firmware? Sorry to bother
Nvm i just didnt check userdata and it worked

Should work. I usually use pdanet vs the native tethering because tmobile can detect native tethering and throttle (happened on my pixel) .

Flash successfully and working now. Will test if anything is broken

So all 4 main files are the same and there is no difference in T-Mobile's modem file versus ATT's? If I grab USERDATA file for TMB, it will flash all T-Mobile's bloatware.
As I remember flashing S7, S8 with a firmware that had TMB wording, where I could distinguish the firmware files. I mainly flashed 4 files on aforementioned models and skipped USERDATA and my unlocked U1 model became TMO and had all the features.
Soon T-Mobile is releasing firmware updates, will see how different they are.

So ive flashed the U1 firmware and it takes but the user data refuses to take and my phone is stil saying vzw/vzw/vzw

Could you clarify the exact actions you took, step by step? And which odin?

Here's the procedure that worked best on the S9s, to convert firmware on a U model:
1. Wipe in recovery -->reboot bootloader-->flash U1 firmware
2. Upon boot, watch for the popup that says "your device will restart to apply new carrier settings", and do it. Make sure your desired SIM is inserted for this step.
3. After that finishes, power off, boot to download, and flash desired U firmware with non HOME CSC and desired U USERDATA. That should give you all the desired carrier settings - and bloatware.
Also, G973U and G973U1 firmware is now live and downloadable in SamFirm. Getting U1 (at least for now) requires manual entry - Auto will not work. U firmware is up for these carriers:
Xfinity Mobile
Spectrum Mobile
Sprint
T-Mobile
Metro
US Cellular
Verizon (have to use Manual entry - Auto will not work)
So going forward, I'll only be adding full builds if I can get them before they hit SamFirm, and only if there isn't build for that month already (eg. I won't add any more February builds since SBA is already up.). I will try to stay up to date on USERDATAs for AT&T and Cricket, since AT&T won't let their firmware be put on SamFirm.

I have an G975U1 and I attempted to flash the U1 firmware using 3.13 out of curiosity.
The first time it failed.
When the device steps through the necessary steps for Verified Boot, it failed.
VBMETA was referenced as was the partition table. So I can only surmise that the new VBMETA.IMG information doesn't match that which is stored within the device's partition tables.
I, unfortunately, didn't capture the the log nor the screenshot.
When I put the device back into 'Download Mode' and tried again, it passed.
I am going to try a CSC change from G975U1 to G975W using Odin 3.13B but I doubt it will work.
.....
And my attempt to change G975U1 to G975W using the Bell combination files failed. It provided the same error messages regarding VBMETA. See attached logs and screenshot.

Flash T-Mobile firmware on Unlocked Note 10 plus version?

I was wondering if we can flash T-mobile firmware on note 10+ unlock version.
I remember 8 series it was doable without any issue. Anyone had this done so far ?

I loaded TMO on my unlocked Note 10+ . no issues for me.

Where did you downloaded tmobile firmware? Can u see video call features?

If you use home csc file during flashing, it shouldn't delete data. I personally use regular csc file which resets the phone. Since you are flashing a bit different firmware I would suggest you to use regular CSC file so it would wipe the device. Use Samsung backup from your phone, to back everything up, including homescreen, your settings, your apps and so on

US Unlocked models are U1(XAA code) and carrier versions are U.
So T-Mobile version of Note10 (regular) would be: SM-N970U and CSC(or the region code) is TMB, that is what you could type in the search fields of SamFirm

Does this looks okay from sam mobile?
Extract the firmware file you just downloaded. You should get 5 files:
AP (System &Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC_*** (Country / Region / Operator)
HOME_CSC_*** (Country / Region / Operator)
Add each file to it's respective field in Odin v3.13.3. Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data.

Yeah, after that you would use Odin to flash these files. Your list didn't include USERDATA file. So total should be 5 files when you flash it. I have attached Odin, just unzip where you like

If you haven't done it already. - On your phone go to settings>accounts and backup>backup and restore, then do back up
After that is done, turn off your phone. Then press and hold Vol up and down + power button. Release power when you see Samsung Note10... wording on screen. The download mode will ask you if you want to continue, use Vol up to continue
Now into Odin app, you will place each file into the corresponding spot: BL, AP, CP, CSC and USERDATA.
The last step is connect your phone to your PC and in the Odin app you will see under ID: COM(will turn blue)
Now if you are ready, start it If successful, Odin will say pass, I think

General G996U and G996U1 Firmware Links and Flashing Discussion Here

For those who aren't already aware, G996U is the model number of all of the US carrier versions of the S21+. The G996U1 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 pay for a subscription to a site that gets the official releases (usually) before they hit the 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!

U1 firmware: https://www.androidfilehost.com/?w=files&flid=322092
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 to an S21, 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 Sx and Note x 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
SPR = Sprint
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
- the correct procedure for switching from one carrier's firmware to another is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want

Initial U firmware and AT&T USERDATA are posted, along with U1 firmware. U firmware is not yet accessible in the firmware download tools like SamFirm and Frija, but if anyone wants a different carrier's USERDATA (for flashing bloatware to a U1 device or for converting a U device from one carrier's bloatware to a different one), let me know and I'll get it for you

Are the firmware in OP compatible for the S21 (Non-plus)?

This thread is in the S21+ forum, not the S21 forum.
This thread is for model numbers G996U and G996U1, not G991U or G991U1.
If you're looking for S21 firmware, that will be found in the S21 forum

I agree with you

Does the firmware control the SIM lock? So, can you flash the U1-XAA firmware and use say a phone purchased from AT&T on another carrier? Or do you need to do the SIM unlock before flashing?

SIM unlock always goes much deeper than firmware. Flashing U1 will never automatically unlock any model - the unlock has to be done separately. If desired, I can provide a recommendation for a professional 3rd party business to do the unlocking, for any interested users who may not meet the carrier's unlock requirement(s).

Thanks. That's what I figured, but wanted to make sure. I like to get off of the AT&T firmware as quickly as possible as you can't get their updates unless you have an active SIM in the phone.

3.14.1 patched

I don't have my S21+ yet but it will be here soon. I ordered from Samsung and selected the Verizon version as unlocked was considerably more expensive.
Does anyone know what Verizon specific bloatware the S21+ has?
Are there certain apps which can be uninstalled with the U1 version but not the Verizon U version?
Are there any potential speed benefits on the 5G network that would be lost using the U1 version, or features like tethering that won't work?
For updates in the future, would they arrive faster on the U1 version, slower, or the same?
My main purpose in flashing from U to U1 is to free up the maximum amount of space of the 128 GB while still retaining 100% of the speed and features I would have with the Verizon version.
Thank you for educating me! It's been a couple years since I flashed my Note 8.

I order a unlocked S21+ U1 version straight from Samsung and didn't have to put in any VZW info.
There is a buttload of Samsung bloatware but no VZW except fot MyVZX

XAA U1, VZW U1, stock TMB U, and I've tried the TLI U1 above and couldn't get it to work. Using google dialer, I input the codes like *#*#27262826#*#* and as soon as I type the last star it just disappears and nothing pops up. I tried with T-Mobile and Verizon sim.

Dialer codes usually don't work on VZW firmware, whether U or U1. But they almost always work on TMB and all others.

How To Guide F711U and F711U1 Firmware Links and Flashing Discussion Here

(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.

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.

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.

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

Hello, well from my understanding Xfinity is bootloader unlockable after 60days and fully played for. I am wondering if anyone is planning on making a thread for Xfinity specifically. 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.

I think network unlock got mixed up with bootloader unlock. You can unlock the phones for use with another carrier after X days and completed payment.

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
