For those who aren't already aware, G998U is the model number of all of the US carrier versions of the S21 Ultra. The G998U1 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!

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 carrier's firmware 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

That, and so that anyone interested can dig through the firmware for anything interesting.
I'm uploading in order of model number, so Ultra is last unfortunately - and my upload speed is only 10 Mbps. Should be up in the next few hours though
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 anyone know if Is the version SM-998U or SM-998U1 have or not dual SIM?
Thanks for doing this ! My phone arrives Wed and of course I wanna flash the U Home CSC to my unlocked U1 device so I can get the AT&T calling features. Are the ones you've uploaded the latest firmwares?
And thanks again for always taking time to do this!!!
Sorry for the possible silly question, but I am coming back to the Galaxy after 4 years on the Pixel and haven't been flashing for a while.
I am getting an Ultra from T-Mobile. If I flash the U1 (to remove the bloat) and then follow the instructions above, it says it will put the carrier files on there. Will that just put the bloat back on? I guess I was wondering if it would make it "stock" going forward. I just wanted to figure that out before I set the phone up since it requires a factory reset. Thanks!

No, that's not what it says - I think you're mis-reading. Flashing U1 removes bloat, period. If you want the bloat gone, you have no need to do anything else other than simply flashing U1 firmware

Oh perfect. I checked again after your post and my confusion was at
"the correct procedure for switching from one carrier's firmware to another is". I was thinking it was the procedure to switch from a carrier firmware to any other firmware including U1. So the re-adding of the carrier files didn't make sense.
Thank you very much for your quick answer!

Go create your own thread if you're going to post links other than the ones in my OP
I do have my own thread about these firmwares, I was just including the Canadian bloat free firmware because you only have the US firmwares. The links are to samfw because they update them regularly so people can get the latest releases where as your links are the current version you linked so if you don't update them then they'll be out of date versions. Do you get paid from your Android File Host links or something? What's the issue? No need to be hostile, just trying to help provide information
EDIT:
Also, when you're flashing between different carrier firmware's, you should only use CSC and not HOME_CSC because keeping the user data sometimes includes the bloat apps preinstalled.
The rule of thumb is if you're CHANGING anything, start fresh with CSC
If you're UPDATING from the same carrier firmware to a newer version, use HOME_CSC.
So for anyone using this guide, it's not recommended to use HOME_CSC when converting over to the bloat free firmware as it's a different carrier release. Not saying it won't work, it's just not recommended, almost like a dirty flash so it could cause stability issues down the road after a few OTA's or something.

XAC is for model G998W. The title of this thread makes it clear that this is only for models G998U and G998U1. So kindly delete your posts, and keep them in your own thread
Okay, post deleted, but it's probably worth noting that you don't know what the G998W is. Because it's the same phone as the U and U1. During the One UI 3.0 Beta on the S20 Ultra, I flashed G988U on my G988W, and when the beta continued onto the U1, I flashed those firmware files as well. The Canadian S20/S21 is just a non branded T-Mobile with more supported radio bands in the firmware.
If you actually look at the carrier info for the S20 Unlocked U/U1/W firmware, they all say XAC and XAA at the bottom no matter whether it's U/U1/W. They are all the same phone and Samsung even uses the same firmware merged, just different radio bands, and because Canadian radio bands support ALL bands, it makes the W firmware the a merge of both U and U1, so it's actually the better choice from what you have posted because it supports every U/U1/W the best. So your post is relevant to the W models whether you want to accept it or not.
That's why I included a link to the firmware, because it's the same device, same flashing process, completely same procedure, so this thread IS relevant to the W models even if you said U and U1 only, the W is also included in that even if you didn't say it was, doesn't make it true.
Also the only difference between U and U1 is U is unlocked but INCLUDES carrier bloat, U1 is unlocked and has NO carrier bloat.
So, closing info here.
U1 is unlocked, no carrier bloat, US radio bands
U is unlocked, HAS carrier bloat, US radio bands
W is unlocked, no carrier bloat, ALL radio bands
You just need to make sure it's the SM-G998W for AXC and it's the best choice with no bloat.
Just because you clearly didn't know this about the W phones, doesn't mean you gotta get all snappy, I'm just trying to help the community.

1. Not mad at all
2. It's the same device internally, yes. But this thread is about software - not hardware. And the software being discussed is the USA firmware, not the Canadian firmware.
sorry I've also been out of the firmware game for a while too. I have a U1 from Samsung unlocked S21 Ultra and need to put the ATT carrier firmware on it. If I'm reading this right, I'm using Odin and flashing the XAA U1 firmware without a sim, when it reboots and reads updated SIM carrier setting at reboot then I am shutting it down and immediately attempting to install the ATT U1 firmware (all BL, AP, CP, CSC (non HOME CSC)? I don't see where I would select USERDATA but I need the ATT options (was going to exchange it but I got all the incentives)

1. If your phone is already running U1 firmware, there's no need to flash it again
2. If you don't see the USERDATA slot, you have a very old version of Odin
It is running U1 but I need the ATT bloatware.....I'm on FirstNet and the only way it will connect correctly is if it's running the ATT built in config files. So I'm trying to go from clean to dirty!!

I'm on sprint and I used the Samfirm app to download the sprint firmware. Model SM-G960U and Region SPR.
I found some other sites with more files but not sure which would be proper ones to use nor do I have a way to get them as seem to require payments or premium download services.
They seem to be much larger in size so probably the full files we'd want?
http://samsung-updates.com/details/122078//SM-G960U1/SPR/G960U1UEU1ARBG.html - This one seems to indicate the unlocked model (U1) number but yet is SPR firmware somehow??
http://samsung-updates.com/details/121907/Galaxy_S9_SM-G960U/SM-G960U/SPR/G960USQU1ARB7.html - this one seems like it maybe the actual sprint one for the sprint model?
https://firmware.gem-flash.com/index.php?a=browse&b=category&id=14757 - This site seems to have other files with different names too. Maybe this is one without the security patch, IE the very first FW?
I like others purchased unlocked but want to load the bloat version to gain the extra features but want it to be able to auto update and be just like the branded ones.
On my old S7E people just had simple instructions with a single file or two to flip between unlocked and locked. This file the OP posted seems too small...

There's no guarantee you can convert. I convert from U to U1 every day for my customers. I don't think I've ever gone the other way though.
But if it's possible, you'd need to flash the full firmware with wipe CSC and SPR userdata, and then afterwards insert a Sprint SIM until you get the prompt to reboot to apply the CSC features
I’ve done it on the S8 I had the S8U and flashed to the sprint version and it worked just fine. Not sure what I’m doing wrong do I need he U1 firmware? It’s been a long time so I can’t remember

No, U1 *is* what you purchased, if you got the unlocked model. Did you do everything I said, including inserting a Sprint SIM and watching for the reboot prompt?
Yes I flashed all 5 files and left the sprint SIM in there. The boot loader didn’t change to the sprint logo either like it did on the S8.

As long as you flashed USERDATA_SPR, that's what contains the carrier customizations. If that alone didn't do it, and if you didn't get the reboot prompt afterwards, then it might not be possible
I think the problem are these files are wrong/not the full conversion.
In my post with the links I put above I found the following.
http://samsung-updates.com/details/122078//SM-G960U1/SPR/G960U1UEU1ARBG.html - This one has U1 in name but states SPR, this seems to match these exactly.
Problem with this is that means it is U1 firmware with SPR user data. This means your bootup logo would NOT change to sprint because it's not the full sprint package which means other FW tweaks carrier specific would not be included, only userdata which would require a factory reset to possibly see by itself.
The one the OP found seems to be just the normal U1 firmwares with the data part different only, thus your boot logo etc. would not change because it's the same one and not actually the sprint one.
We actually would need this one:
http://samsung-updates.com/details/121907/Galaxy_S9_SM-G960U/SM-G960U/SPR/G960USQU1ARB7.html
Oddly they both say Feb security patch yet are different FW version, BUT the model in this one is NOT the U1.
I could be wrong but I think this is the issue but no way to confirm since I can't get these other files...

You can flash it using modded or patched ODIN to the U1 non-carrier firmware to get rid of the T-Mobile boot animation. It will also remove the T-Mobile video calling dialer though but WiFi Calling will still work.
What he said^^^ flash the U1 firmware. Note your device will be wiped.

Well that doesn't matter to me. Have never used it yet so it doesn't matter if I wipe it. But will I get regular updates if I flash it with u1 firmware ?
And which firmware should I select it exists a few on this page or do I need to take the tmb one for T-Mobile but I'm not using T-Mobile and will probably never do

Well that doesn't matter to me. Have never used it yet so it doesn't matter if I wipe it. But will I get regular updates if I flash it with u1 firmware ?
And which firmware should I select it exists a few on this page or do I need to take the tmb one for T-Mobile but I'm not using T-Mobile and will probably never do

Do not use the one labeled TMB U1. That firmware isn't official and could potentially break OTA's. You want to use the U1 XAA with the same version or newer bootloader than what your device currently has. The the first character of the last five characters of the build number contains your bootloader version. I don't believe the Note 9 has a v2 bootloader yet, but I have only really followed ATT U firmware, U1 firmware, and TMB U firmware. When you flash, do not use the HOME_CSC! remember your device will be wiped and factor reset so back up what you want before starting.
I'm running the TMB U1 firmware. No bloat or boot screens and I get OTAs around the same time as the U t mobile devices. I honestly dont see a real difference from the XAA u1 vs the TMB U1 firmware to be honest
Well that's it's not a problem haven't started to use the device yet. But it's not any risk that I'm brick my phone when flashing with u1 firmware.
One thing I noticed it exists unbranded firmware what I can see on Samsung's page for n960U can I not use that firmware ?
But I should not flash home_csc ? I'm guessing that contains special files for u1 ?

The non-branded firmware is the U1. The reason the modded or patched ODIN is needed is to skip the check that you are flashing the same carrier firmware. The hardware for the US and Canadian models are exactly the same. The firmware on Sansung's page isn't meant for flashing in ODIN.
Although I have only seen one user experience issues with the TMB U1, which for some reason, gave him a modded software warning when they tried to check for updates. I would stick to using the actual non-carrier specific firmware, which has T-Mobile's WiFi Calling and still has band 71 enabled.
ok so the SM-N960U is carrier branded and the SM-N960U version ubranded i thought it was some more technical difference between the different models.
Well the phone i have is new just carrierd unlocked but it's coming from t-mobile but i'm not going to use it in usa right now. So unless i need to have t-mobile's software i gladly skip it and use unbranded and that is the "U1 XAA" i need to use ?

The U is carrier specific, the U1 is a generic non-carrier specific firmware that should work with most US carriers, and the W is the Canadian equivalent of the U1. The hardware for all three is exactly the same.
The unbranded and non-carrier specific firmware does have its advantages. No carrier bloat, it works well with T-Mobile, and if you switch carriers, the phone will reconfigure for the SIM inserted. The only time the U firmware is recommended is if you need a specific feature for a particular carrier that isn't available in the U1 firmware. Video Calling for T-Mobile, WiFi Calling on AT&T, and so on.

Ok so with other words i can use the unbranded XAA firmware and keep OTA now. But if i ever want to use T-mobile or AT&T further on i just install corresponding firmware for that carrier right ?

That's correct! The U1 non-carrier firmware is like a stepping stone, If you want to move from one U firmware to one from a different carrier, you need to flash to U1 first and always make sure you never use the HOME_CSC. The HOME_CSC doesn't wipe the device, which can cause a number of issues when converting. Being on the U1 though, makes it very easy to go back to any U firmware because you are already at the point where you could just straight flash to any U or W firmware as long as the bootloader version is the same or newer than what your device has at that time.
ok thanks for all advice
just to be curious because i don't know but wish to learn. Why should u never flash hone_csc and what does that file do?

The HOME_CSC prevents wiping while flashing. If you skip the wiping part, you risk having no data, no potential cellular connectivity, no different unlocked bands for the firmware you are flashing to, etc. You pretty much put yourself in a position where you have to flash again, but actually use the other CSC to ensure your device works properly.

Hello all. I am new to this community. I have read several of the posts that mention that the US Snapdragon variant of the Note 9 cannot be flashed with TWRP or custom roms. However I see that based on this post regarding T-Mobile that the U1/ublocked variant can be flashed with any of the other U variants as long as the bootloader is the same. Does this mean that I can flash the T-Mobile firmware on my unlocked note 9? If so can anybody guide me on how to do this? I am trying to go back to having T-Mobile's built in multiline and voicemail functionality which I lost after going from the T-Mobile branded Note 8 to the unlocked Note 9. Thanks!

Yes you can. Use ODIN to flash the T-Mobile firmware. It's that simple. You don't need an unlocked bootloader or root. No it won't trigger Knox.
If you need detailed instructions, they have been posted in some of the firmware threads here, o you can go to the Note 8 forums and read through the carrier switching thread. Just follow the steps for flashing carrier firmware. The steps are all the same, you just make sure you're using the right firmware for your device.
Thank you so much! I was able to successfully flash to T-Mobile using the forum threads.

That's because U1 XAA is on ARJ9. There won't be a U1 Firmware with an ARH6 build number.
As per the title, bought an unlocked G970U instead of U1 by mistake. Should I expect a Verizon splash screen greeting me in the bootloader? I don't wanna see any branding anywhere in my phone. Can I get rid of any of that flashing U1 firmware?

Which G970U phone you have bought. If it was a Verizon branded, then their logo should greet you If you bought T-Mobile variant, then its logo will be present while booting the phone. Flashing is possible and it depends which carrier you have. Also don't you have the phone in hand yet?

Yeah, the phone hasn't arrived yet. In the pictures I can see the box has no carrier logo, but I'm guessing it's Verizon because I haven't seen a Verizon branded box yet. Also, the box definitely says G970U.
I've been a Nexus/Pixel user all my flashing life, so I'm well versed in the fastboot/adb dark arts. How does this compare to Odin? There are so many new terms that I'm still trying to understand: CSC, HOME CSC, USERDATA, etc. Is there any guide I can follow to flash my incoming phone to U1 firmware?

The T-Mobile version is also G970U, so it can be pretty much any carrier. USERDATA file is present in carrier firmware, if you flash unlocked firmware you won't need/have this file.
Link below is for S8, but works for S10 as well. Of course you would need to use firmware files for your phone. I would also use instructions under "Flashing standard firmware" first using Standard Odin. If you get an error when staring to flash, then use (Patched) Prince Comsy's Odin.

Thanks a lot. One last question. I'm based in Mexico (we only get Exynos here), so I got a U version to get the Snapdragon CPU. Obviously I don't want any US carrier branding/blotware in the phone since I couldn't benefit whatsoever from it. What about OTA's, though? Will I get them whenever Samsung releases an update for U1? Or will that depend on my carrier? Should I update monthly using Odin? Do I have to factory reset? So many questions :silly:
The link you provided doesn't work, btw. But I've since found some other Odin guides. Thanks!

I corrected the link in case you need it.
To answer OTA question: I had unlocked U1 model of S8 and when I flashed it with T-Mobile firmware then my phone got OTA from T-Mobile when they release it. I assume if you have carrier branded phone and flash it with U1(XAA) firmware then most likely your phone will get updates when Samsung releases them. You won't have to use Odin every time there is an update if you flash properly. Also, it would be advisable to flash using CSC file instead of HOME CSC, so your phone would be wiped. It is because you change firmware and want your software to be fully compatible. After flashing and you check your phone's software update and see that is shows "not compatible or something similar", then I would just suggest you to do "reset"(factory reset) from setting and after you setup your phone, that message will disappear. Also don't do any software update before flashing as you phone may get a fresher firmware than the one you might be trying to flash.
1) Check your current phone firmware
2) Download firmware you want, but if you can, get the firmware that is a previous one than the current one, so you will check to see how your phone gets OTAs
3) Flash using Odin
4) After that disconnect and let the phone do its thing
5) Set it up and check to see if software update section in settings don't give you any messages such as the one I outlined above, if it does, just factory reset the phone
Please excuse any mistakes I make as this was my first time flashing firmware. So anyway, I have a Verizon S10. I got tired of Verizon’s bloat and all the missing stock features so I flashed the Unlocked Firmware from Sammobile. As I had no prior experience, I did research and came to download the latest U1 firmware with the XAA CSC. I know there’s a U1 version with the Verizon CSC, but I decided to use the XAA version because I knew it was universal. Now I could be totally wrong on this, but isn’t at least one of the three CSCs supposed to be XAA? All mine are still VZW, just like it was on the original carrier fw. I even tried taking the Sim out and reflashing, but no luck. The phone is still locked to Verizon, could that be why? The problem is, can I still get OTA updates? How can I stay on unlocked firmware and get them? Did I mess up and should’ve flashed the VZW U1 fw? Is this fw all vzw cscs too and I just messed up somewhere else? I have the pda of the xaa version with the csc of the vzw version. I don’t know what to do. I would’ve loved to install the one ui beta now that I’m in unlocked fw, but I can’t because my active csc is version, who blocked it

Some answers to your questions:
1. I don't know, it should flash a data partition that's for the unlocked firmware. I remember reading that somewhere here in the forums.
2. I think Verizon phones are more locked than the others, but I could be wrong.
3. You can get the OTA updates on the unlocked firmware, you just have to have a SIM inserted.
4. You may have, do a factory reset in recovery and try flashing this with that special version of ODIN:
https://www.androidfilehost.com/?fid=1899786940962609128
5. U and U1 firmware are different, sort of. U is carrier and U1 is unlocked.
For those who aren't already aware, G991U is the model number of all of the US carrier versions of the S21. The G991U1 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!
U firmware: https://www.androidfilehost.com/?w=files&flid=322084
U1 firmware: https://www.androidfilehost.com/?w=files&flid=322085
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)
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
Thanks for the firmware links!
Odin blocks flashing from U to U1 or U1 to U. To successfully flash: Use the patched/modded odin found here.
Patched Odin 3.13.1
For those looking for a modified, modded, or patched odin that is a newer build than all the fake and renamed prince comsy 3.12.3 versions floating around. I patch recent Odin versions to offer similar functionality to the princecomsy; in that...

I don't guarantee that any particular bands will work on any particular firmware. Also, carriers don't use every single band in every single area
