Help...super confused?// - Samsung Galaxy Note 8 Questions and Answers

So I have a note 8 model sm-n950u1 and I am currently using a freedom mobile (GLW) SIM card and all is good. The problem is that my on phone software update will not work , I get a registration failed or process failed error even after a factory reset. The model on my box indicates smn950uzkaxxa. I want to update to Oreo and the firmware is now available online but am unsure what firmware to get.. should it be the Oreo for the sm-950u1 with the xaa extension? Or should I just flash the freedom mobile firmware for the Canadian variant sm-n950w? I am leaning towards the first mentioned and what files in Odin do I need to flash as there are like 5 options. Thanks in advance,,,any help would be appreciated.

Anyone????

I would say use the freedom one because my U1 updated to the Verizon U1. They are the same firmware across the board but optimized for each carrier without the bloatware.

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

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.

No ota pie update on note 8

Hello, I recently bought the note 8 but I am not receiving any OTA updates on it. Here's the software info on it.
Android version: 8.0
Service provider SW: XAA/XAA/TMB
Baseband version: N950USQS5CRK2
My current location is Pakistan and maybe that's why I am not receiving an OTA. However, I don't know which firmware should I flash to keep the phone unlocked on my current carrier and upgrade to pie. Any help or guidance in the right direction would be really appreciated.
Thanks

You need to flash the unlocked N950U1 firmware version on the phone that way you might be able to receive the updates from Samsung directly.. If you stay on the N950U firmware version (it's T-Mobile that you have) you'll have to do the updates yourself from now on since updates on N950U only come from the carrier's in the USA.. Follow @BlueFox721 directions on this link and you'll be able to flash the real unlocked firmware..

Will this affect any unlocking previously done on the phone? and which version of Odin should I use? it has listed 2 versions a simple and a modded one. And kindly guide me which firmware should I download, there are carrier specific ones and there is one called the unlocked XAA

I have no idea whether it will have any effect on the phone being previously unlocked and I don't think it would since it's unlocked firmware meaning unlocked from carriers already but you never know it could relock for all I know and then you'll just have to unlock it once again.. The directions should tell you which Odin to use and it's the modded version and the XAA is the unlocked version of firmware without the carrier specific crap loaded all over it.. I would ask around about the unlock first though since I didn't have to worry about that I don't know the answer to it..

Hey, I just searched for samfirm.exe, seems like it is deprecated. However, I saw it was getting the firmwares from samdb.org so I went there and searched for the firmware. Turns out, they have the same slow speed download for free users so I'm stuck here. Do you have the firmware in your PC? Can you upload it on GDrive maybe and send me the link? any help would be really appreciated. I usually get 1.5Mbps download speed but these downloads go only as far as 400kbps :#

AT&T S10 flash stock firmware from XAA

I flashed my AT&T S10 SM-G973U to XAA after unlocking to for use on T-Mobile. I can't seem to flash it back to stock, I always get an error usually after abl portion of Odin flashing. I am sure if I am using an incorrect Odin or what. Can some please guide me in the correct direction?

You mean you want to downgrade?
Actually it's kinda impossible, Samsung forbids flashing firmwares prior to the last security patch, no changes will be made.
I wouldn't say necessarily downgrade, but to flash my phone back to AT&T branded firmware like it was when I got it. I know that when I do a SIM card change yes it does change the firmware and branding but it's still XAA

Did you have any issues changing your AT&T S10 into XAA ? I'm planing to do exact this.
What gets me is, you can't find AT&T firmware anywhere except on shady looking, but legit pay sites so you pay for it when it should be free like all the other carriers firmware.

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.

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

Question Which CSC code to use

I have a U.S. Unlocked (snapdragon) S21 Ultra that I'm currently using on AT&T (SM-G998U1). Using the dialer method, I obtained my CSC of OYM. Frija will not recognize OYM which I guess means multiple CSCs are supported? I don't want to install carrier-branded software. I tried the CSC code of USC and Frija accepted it. Is this the right code to use? I don't want to install the wrong firmware and brick my phone. Any guidance will be appreciated

So if you don't want to install AT&T Firmware then the best option is to stick with the USC Firmware which is the software on your device. What's the motivation to replace your firmware with the same firmware already on your device? Your Primary CSC can't be changed, it will always be USC. Changing firmware with a different CSC typically causes more problems than it solves. OYM means it's a Multi-CSC phone, USC is your actual Primary CSC. Whatever service provider's SIM you use will be the Active CSC. One drawback in Unlocked Samsung phones is they are the last variant to receive OTA Updates.

The motivation is I'm tired of waiting a month after release of updates to get it on my device. This particular update is supposed to offer camera improvements of which I'm anxious to see. No, I don't want to change CSC or carrier software. I just wanted to make sure I was using the correct code for my device. I'll give it a try shortly and thanks for your help.

I got it updated. The zip file app I was using (IZArc) kept returning an error on the AP file. I switched to 7-zip and problem solved. I got a pass from Odin and phone rebooted into the OS so all is good. It should go fast and easy next time. Thanks again varcor for your help.
That's great, next time you're looking to see if there's an update try Smartswitch. Much easier than flashing firmware.
