For those who don't know, G960U is the model number of all of the US carrier versions of the Galaxy S9. The G960U1 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 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 (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.
Odin 3.13.1 3B Patched is required for flashing these.
Happy flashing!

U1 firmware: https://www.androidfilehost.com/?w=files&flid=257047
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 S9+, 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
- 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. 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

Starting with the S8, firmware is universal. Bloatware and carrier customization is determined by the USERDATA file that you flash

I don't know if you can *only* flash USERDATA by itself. I suppose if the Build is the same, you can try.

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. Maybe the files from the samfirm app are not for sprint I don’t know but for region I put in SPR just like I did with the S8 or maybe I got them from uodato I can’t remember honestly

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...

What model do you have? And what firmware version were you on before trying to downgrade? Some firmwares include bootloader updates which cannot be rolled back.
I have a N950F and this is the Oreo image I succesfully flashed "BL_N950FXXU3CRC1_CL13094739_QB17155977_REV00_user_low_ship.tar"
I can flash "COMBINATION_FA71_N950FXXU3ARA5" without a problem which is 7.1.1 But I think it's the bootloader that is giving me issues and since the combination file doesn't include a bootloader (AFAIK) it goes through, but when I try to put in any bootloader from Nougat, the flash fails.
I tried flashing:
-BL_N950FXXU1AQI1_CL12007350_QB14830234_REV00_user_low_ship.tar
-BL_N950FXXU1AQHB_CL12007350_QB14652984_REV00_user_low_ship.tar
and both failed. It's important to note that I'm trying to flash the whole thing, not just the "BL" file. I just pasted the BL file name because I think it holds the information you need.
Ok thanks for providing the info. One more question, what Odin version are you using?
It is not possible to downgrade.

3.13.1
I have a similar problem. Bought my N950F in Panama but I'd like to change to Brazil's ZTO(unbranded) to be able to use Samsung Pay there.
I got Odin 3.13.1 and the ROM N950FXXU3CRDF_N950FOXM3CRE4_ZTO (latest 8.0.0) from SamMobile. When I try to flash I get the "Check Fail BOOTLOADER" message. Trying to uncheck the BL, I get another error but also not able to flash. Maybe my phone has a newer version that doesn't allow it to in theory "downgrade"?
Any solution?

Hi, yes you are on the "U4" bootloader and trying to downgrade to the "U3" bootloader (look at those characters in the build numbers, that's the bootloader version). Can't downgrade from u4 to u3 though.

I have a ATT s7 edge. I was running on g935AATT4CRE4. Oreo. I found a firmware that was a 935U firmware. I flashed it with Odin with no problems. I liked it a lot. I wanted to go back and compare the 2. I know, kind of dumb. I had issues flashing original firmware listed above. I did some research, I downloaded latest att software and flashed it. Worked fine. Here is Build number G935AUCS8CRK1 . Now I cannot go back and flash the 935u firmware. I have noticed the 5th digit from the end is now 8 and not 4. Could this be issue? Any ideas.

You need to download and flash the SM-935U 8.0 firmware that matches your baseband version exactly if you scroll down you will see an USA(AT&T) version that matches your baseband that is the one you need.

use your last valid twrp backup from before the issue to restore:
carrier configs (odm)
efs
also when you flash full stock, use csc.md5 and not home_csc.md5 as CSC file.
it migh be good to research what the very latest firmware files are for your device. there should be a july update somewhere. so use that and try again.
if you want and try to fix ure csc issue try to flash zip in:

Hello everyone i've been really struggling with updating my phone that i got pre-owned It's a Samsung Galaxy Note 9 (SM-N960U) and I have not recieved updates since I got it the phone is still on Android version 8.1.0 and security patch from 2018 so i've been really wanting to update it to the latest version but I couldn't and i figured out that phones from AT&T only update via their own app or OTA thing anyway I thought of flashing it with a stock firmware VIA ODIN but i checked on sammobile that the note 9 AT&T csc only has 1 update and thats 8.1.0 also so i was wondering if i can use some other firmware to flash it or do i change csc? would that work if i changed the csc or am i gonna have baseband and signal issues? I tried KIES it said it didnt recognize my phone probably because the software version has never been updated and very old , i wanted to flash it to a different CSC than AT&T but i dont think thats a good idea, please help

Kies is for older Samsung devices, Smart Switch is for newer Samsung devices.
Here is a list of firmware at Sammobile that has android 10 for your device. They are for T-mobile but I'm pretty sure it can be used on the AT&T Note 9.
https://www.sammobile.com/samsung/galaxy-note9/firmware/sm-n960u/tmb/
Here is a thread for AT&T note 9 where another user flashed their Note 9 with firmware from another carrier. Use the T-Mobile firmware and follow the steps from post #4 of the thread linked below.

So, all the SM960U devices are the same. Just flash the T-Mobile firmware.

oh alright, tyvm im gonna go through with it and update you how it goes, ty for the help and response :highfive:
Hello people, having exactly the same problem, so its a SM-N960U phone, unlocked from AT&T. First to say, im not in the US, dont have AT&T sim, the phone is updated to android 10 with 2.0ui, with baseband ver. N960USQS3DTB1.
Now somewhere i read that bootloader must be unlocked in order even to begin thinking of flashind the device, dont know how accurate that is... Id like to ask the Owner of the post, if he was able to make it, to update his firmware. And if so did he indeed succeded from the link above from ep1kku ?

No, the bootloader does not need to be unlocked before flashing if you are flashing stock software, unlocked bootloader is required to flash custom software, not stock software. There are some manufacturers that require unlocking bootloader even when flashing stock software but Samsung is not and probably never will be one of them.
You can flash your device with stock firmware any time you want, provided that the firmware is not a firmware that is older than your currently installed firmware and if the firmware is for your model number or an equivalent variant of your device with a similar model number and the same CPU series.

You can boot into download mode and it should say whether the firmware is "official" or "custom".
As I said, you can flash stock firmware provided that the firmware that you are flashing is not older than your current firmware, you can't downgrade the firmware, you can only flash an equivalent firmware to what is already on the device or a newer, updated firmware. Your error may be due to this. For all Samsung firmware, the 5th character from the right in the build number is referred to as the binary version. Your currently installed firmware has a "3" for the binary version, this means you can only flash a firmware that also has a binary 3 or you can flash a firmware that has a number higher than 3 but you can not flash a firmware that has a binary that is lower than 3(you can not flash a binary 1 or 2 firmware).
Depending on the specific error that you got, this could be your issue. What was the specific error that you got?

I got you, well iv got into download mode many times, its say official, so in theory i can flash official release right, but keeps ending with that odin error, no idea ... Could it be because im in different region than the device's market, its a US market phone like i said, in from europe

When using Odin, in the box that shows the flashing process, it should say exactly which error you are getting. When I asked what error you are getting, I was not asking "why" you are getting the error, I'm asking what it says in that box. Post the exact name of the error. Try to flash the device, while it is flashing, watch the dialog box in Odin, when it gives the error, take note of exactly what the error is, you can scroll up and down within the box and read all of the output data in that field.
Yes, it could be due to being from a different region but I doubt it. It could also be because your device is a Snapdragon version but the firmware that you are trying to flash could be for a Exynos version instead, or vice versa.

You still aren't telling me the SPECIFIC error that you are getting in the dialog box in Odin. That has been the most important question to understand your issue but you keep dodging it. Flash the firmware, watch for the error, take note of exactly what error it says it is, then post exactly what it says the error is. If you can't post that then there is no point in replying.
If you are trying to flash the device in a different region, you may not need to flash the whole firmware from the different region, you may be able to flash just the modem.img from the alternative firmware. To do this, extract the firmware, find the modem.img then convert that modem.img into an Odin flashable .tar using 7zip with its highest level of compression, then flash the modem.img.tar via Odin.

I added to my previous post.
Strange, your screenshot doesn't show an error, it just stops without giving an error.
I'm assuming that your firmware came in multiple parts with some CSC files? If so, try flashing without using the CSC files.

Give me a link to the firmware that you downloaded and I'll compare to see if it is supposed to work.

Alright, https://www.sammobile.com/samsung/galaxy-note9/firmware/#SM-N960U this is without the carrier, if you put at&t in search menu, you will see that only 1 is available, with android 8.1
So i tried U1, version at&t https://www.sammobile.com/samsung/galaxy-note9/firmware/SM-N960U1/ATT/#SM-N960U1 also didn't work, i tried T-mobile on same U1 model, also didn't work. Everytime same error/none error like on the screen shot
