I recently purchased the G920t factory unlocked version on Amazon. I rooted it and installed a custom ROM. I was hoping that someone could help me out with finding the stock firmware for the factory unlocked variant. I believe it is slightly different from the standard T-mobile firmware, as it didn't include any t-mobile apps, etc. The reason I was asking is I've been having call quality issues and wanted to flash back to stock to see if it would be resolved, but didn't want to flash to the standard t-mobile stock as I believe it is slightly different. I know I should have made a back up before flashing a custom ROM but I failed to do so and am now trying to fix the issue afterwards.
Thank you so much for any help you can offer.
What firmware was on it originally? What baseband?
My USA factory unlocked 920T shows a baseband of G920TUEU3COK1 after the latest OTA update was installed. XDA rules don't allow me to post links to SamMobile firmwares. You can search their site for "920T", but don't used the "SM-G920T1" search result. The proper firmware has "Cellular South" as the Country/Carrier.
Thank you so, so much. So that'll allow me to roll it back to the way it was right out of the box?

yes, but I don't think it'll reset the knox counter to zero.
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
I've seen a couple of threads about this here, but I'm confused about where I can get the firmware to flash an unlocked S10 (SM-G973U1) to T-Mobile firmware, and they've not really told me where to download the firmware that I need. One thread pointed at S10+ firmware, not useful to me, and the other didn't give any URL for downloading firmware.
Can anyone help me find the right firmware? I've used Odin before, and am fine with that. I also know that I have to have the right firmware for this to work *smile*.
Also, the firmware to flash back from T-Mobile to unlocked would be very useful, since I may want to change back to unlocked at some point. The reason that I want to flash T-Mobile firmware is since I'm still on the May 1 "monthly" Android security update on my unlocked S10. That doesn't make me happy, more than a quarter behind by this point...very disappointed.
Thanks!

If the phone is SIM unlocked, the Firmware you want is the USC or XAA firmware... That way it will switch carriers apps and bloatware when you change sim cards...
Search for samfirm on google....

Hi i am new here and need help with updating my Samsung note 9 i still have a baseband N960USQS1ARI5 but will like to update to the latest firmware. i'm using an unlocked AT&T phone. can anyone guide me? I'm not sure if updating the firmware will lock the phone and the process to update, do I just update the firmware in stages as the updates were released till i get to the latest update or can i update straight up to the latest? I am thinking of using Odin, is that a safe way to do this? any help will be appreciated. Lastly, can I change from the AT&T firmware to lets say a none carrier based firmware so as to stop seeing the AT&T logo on boot up? Maybe switch to a firmware that supports global or international? Does anyone have links to an unlocked firmware update i can use, as well? Please help!
I must state that the phone never updates automatically as it always says the software is up to date.

to your last point, at&t phones are notoriously bad at updating
factory unlocked phones will remain forever unlocked and phones unlocked that are bespoke to a specific carrier will also remain unlocked even with Odin flashes providing that the method employed to unlock it was legitimate. Some unlock methods employ root and only trick the phone into thinking its unlocked. Well, once you remove root, and thusly the trick, the unlock is gone. I have ran across rare examples where the person swore up and down that they unlocked their phone with a legit unlock code and that it relocked to a carrier once the sim was inserted and initial programming completed, but i dunno. Sounds weird to me, but every person who said this also said that the phone locked to a carrier other than the one it came from originally. Take that for what its worth, but i still mostly stand by the first couple lines of this section of my diatribe
If you want the at&t crap gone, get the N960U1 firmware and flash it in Odin. You will need the modified version of Odin to flash it so it can ignore the 255 errors the phone throws up from flashing firmware for a carrier (or, in this case, no carrier) on to a phone that it wasnt originally designated (not designed) for
go to sammobile.com/firmwares, get the info for the firmware you want to d/l, get the Frija tool or Samfirm and download the firmware thru one of those as theyre literally 5x faster and flash it

no update samsung Note 9 AT&T unlocked phone in another region without AT&T sim card
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.

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?

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.

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.

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
