Question Flash T-Mobile firmware on unlocked S21 ultra - Samsung Galaxy S21 Ultra

I'll admit I'm a noob, but I was wondering if there were guides or a way to flash the official T-Mobile carrier firmware on an unlocked s21 ultra by chance? If anyone can point me in the right direction please. Thank you and sorry if it's a dumb question.

The SM-G998U1 is Multi-CSC Device (OYN). Change the CSC to TMO by entering the following code on the TouchPad. *#272*YOURIMEINUMBER# Select TMO then install.

Once last question, forgive my ignorance. Once I flash from the unlocked version to the T-Mobile branded firmware, will I need to manually flash each update that comes out for T-Mobile do you know?

You SHOULD receive Tmobile updates once you're on Tmobile firmware and network but I don't think it's something that can be guaranteed. Your Primary CSC can't be changed to TMO and therin lies the problem. In the last couple of years Samsung has complicated firmware and CSC transitions on it's numerous array of devices. Lots of potential users lean to an unlocked device thinking they'll have more freedom of choice but it won't always end up as a benefit. I always recommend buying your service provider's device for full functionality but it doesn't always work out since some users tend to swap service provider's on a regular basis.

I'm on T-mobile's network, month to month, no long term commitment which adds flexibility but even being on their network I didn't aquire their Branded Device. I have the Hong Kong SM-G9980 variant. I couldn't care less about 5G, to me it's the biggest marketing scam since light beer. The only other feature I lose is Carrier Aggregation which much like 5G enables faster download speeds. I can easily have my laptop handle this and transfer files or data to my device. So there's no carrier bloatware, the bootloader is unlocked, I get updates from Samsung typically sooner than US devices and still have Wi-Fi Calling and VoLTE via Tmobile. Most users don't do much research to define which device is best suited for their needs. "I got this great deal on an S21 Ultra but..." We can point the finger at Samsung as well, way too many variants leads to a lot of problems.

I downloaded the firmware from SamMobile and Odin then flashed it. I had the unlocked version I purchased from Samsung directly. when selecting the csc portion but it still shows the xaa portion as well. Not sure if I did it wrong but seems to be working for me. Putting it in download mode requires holding volume up/down and power. Every site I visited told the wrong directions

Unlocked S8 -> Tmobile

Hello, I'm a tmobile customer that just purchased an unlocked galaxy s8 from the Samsung website. I'm wondering if going to the store and getting the tmobile firmware on it installed is really necessary. I mainly want to do this because of the software updates, but then I thought the the unlocked version might get updates from a different source? Am I right? I'm sorry about this being such a general question, but I just want to do what's best for my new phone. Would you recommend me installing this firmware? Or should I just keep the stock unlocked firmware it came with? Are there any drawbacks associated with not installing the tmobile firmware on it?
EDIT:
To start, will Tmobile even do this in the first place? I'm totally clueless whether they offer installing their software on customer phones or not.
Thank you.
Hi there. Unfortunately, you are going to be really hard pressed to find a T-Mobile rep anywhere that could/would flash firmware w/ Odin. Not saying that there aren't some reps out their that don't know about this stuff (there are a lot that really have no clue though), but this is well outside of what most of them are trained for, plus Odin is only supposed to be used by Samsung. Also, historically (at least the last couple of years), for whatever reason Samsung's unlocked US models have been getting updates slower than the carrier versions, which really doesn't make any sense because there is less to go through to get them updated. That being said, there are several threads in the T-Mobile S8 forum here as well as the general S8 forum dedicated to carrier switching, which can guide you in turning your unlocked model into a T-Mobile model, for all intents and purposes.

The guy that replied first is really correct! T-Mobile store won't flash any phone, don't go beyond simple troubleshooting. It is easier to fly to Mars, than talk about flashing a device with rep. I do hope there are some T-Mobile reps that do really know about flashing, but I just haven't seen one yet.
I am with Unlocked S8 and use it on T-Mobile. I don't have any signal specific issues for example and features such as WiFi Calling, Band 12 and VoLTE all work well. There are few thing that flashing to T-Mobile firmware could give you:
Video calling(to specific phones only)
Advanced Messaging(believe other phone needs to support it)
DIGITS service will be built into the phone dialer.
I was also debating about doing it, but all 3 mentioned features are not wildly available and don't work across all devices and networks. On top of that you will get few T-Mobile apps pre-installed + Lookout app + T-Mobile logo when booting up the phone.
We can flash practically anytime we want, so I would suggest you to wait and see how Samsung will treat unlocked devices and how fast updates will arrive. If T-Mobile will do them much better than Samsung, then I will flash myself or when those 3 features above will work across all devices.
Sorry for reviving this thread, but my unlocked s8 gets slower upload and download speeds than my friends tmobile s8, we are both in NYC and he's getting 100mbps and I'm getting 30-40mbps. I assume they also have specific settings hardbaked in their rom that allows for optimized carrier usage?

the t mobile firmware comes with 4x4 MIMO and 256QAM. which leads to better signal and faster download speeds.
Can I flash just the modem or CSC to get the benefits without flashing the whole tmobile rom?

This is a question I'd like the answer to. I'd like to keep all the Samsung default software features but get RCS, which is the most important thing, and one of the main reasons I'm still using my LG G6.

i think you'll need the whole firmware to be able to use RCS and the tmob features. i personally think the tmob firmware is better since it has 4x4 MIMO and 256QAM enabled. so better signal and service

I don't care about any of that. I value the Samsung unbranded experience more. All I want from the Tmo FW is RCS.
Alternately, if they ever support it using the unlocked S8 FW, i'll switch back to my S8 in a heartbeat. My G6 seems to get tons better battery life anyway for some reason.

I believe you have to use the "flashing unlocked firmware" because the prince's version of the ODIN will bypass the ROM checksum and let you flash any variant you want. if you use the normal ODIN and you are going from unlocked to t-mobile (950U1 to 950U) ROM it will fail.
I used to be on the unlocked but now I'm running t-mobile rom to have multi-line baked in to the native dialer. and my service provider SW ver. shows TMB/TMB/XAA
All is good and I'm happy with the ROM after few days the battery life seems the same as the unlocked version.
i just want to know if i can keep the bloatware free and just flash the modem from tmobile firmware.
i just want wifi calling, volte, 4x4 MIMO and 256QAM. i dont care much for the multi line feature cause not useful on my end and idk about rcs because the person on the other end needs to have it and i dont really see it as useful.
lol s7 bloatware free firmware was so easy to flash compared to this xD
im running the att variant but im sure all the hardware is the same. so i dont see why the unlocked firmware wouldnt support this out of the box.

When I had my S7 Edge I was able to mix and match different ROM with different modem files ie I would be on the unlocked ROM with the tmobile modem and was able to use the unlocked firmware with t-mobile radios. This is what you want but I have not tried it with the my S8 you can try if it dont work use the prince's ODIN to take you back to stock.

Isn't "flashing unlocked firmware" means that you have a carrier provided phone and want to flash unlocked firmware on it?

Correct, but it also works the other way around. Anytime you want to change variant you must use the modified version of ODIN as it bypass the checksum or the flash will fail.

Can i flash the sm-g977b firmware onto the sm-g977n device?

Hey 5G Pioneers,
I am wondering can I flash the sm-g 977b firmware onto the sm-g 977n device through the Odin? Did someone make it?
Since these two models are all using the same Exynos 9820 chips
And from my previous experience of using my galaxy s8, Samsung actually enabled me to flash the firmware in different regions only if the devices were using the same chip version.
I am currently in Australia. The Korean version of 977N is much cheaper, and it seems that is the only network unlock version that I could buy from the market.
Not sure where are you in Australia but I bought mine from a Telstra Sales Rep (based in CBD, Melbourne) where he got a discount code and gave its to me for AUD 1400 for the 512 GB Majestic Black Version, unlocked , I'm using Optus, VoLTE, VoWIFI works fine on it.

Hi everybody,
On Sammobile website, I found 4 firmware Korean variants. I tried getting more information on the "KOO" variant to see if its a stock Samsung firmware without Carrier Apps/Bloatware without luck. I couldn't get any detailed information whether it can be flashed over any other Korean variant. Can anyone here clarify if its possible and If yes provide further details?
Attached a snapshot.
Many thanks

That is the non bloatware Korean version but it doesn't allow me to flash it. I suspect you have to flash it with the userdata file also.

Hi,
I did disable the apps which is great, but there menu operator items as well!
Edit : Forgot to mention that the boot logo is of the operator as well.
I was researching something about using the PIT file along with the firmware but can't find the specific PIT file for S10 5g.
Use Odin or the modified version to flash combination firmware. Then flash your desired firmware.
This is the only way I am aware to remove all carrier bloatware and boot logos.
Dual SIM

I am particularly interested in this as the 977N variant seems to be dual sim. I notice it also has additional bands to the 977B varient and I would like to put the telstra firmware to ensure operation of VoLTE VoWiFi RCS etc.
The main purpose is to use at home and overseas. So more bands and access to features (VoLTE, VoWiFI, RCS etc. on my telstra SIM and local overseas SIM) when overseas are the goal.
Unless someone can confirm that the 977N with vanilla firmware will support all the telstra features?
Thank you for your assistance

Correct, but that's typically something the person wanting to do the process of flashing firmware on a $1k phone should research or ask about here on xda. As much as I love helping to provide information, it is best for the user that is wanting to undergo the process better educate themselves on what they are about to tackle.
If it had the likelyhood of causing a brick, I would definitely tell them straight away. But other than that, we all get a nice sense of accomplishment when we do flashing that we weren't too sure about. At least I do.?

Looking for Samsung Galaxy Note 9 Official Stock AT&T Rom for my unlocked phone

I bought a Note 9 from Amazon I thought it was an official AT&T phone but it is the unlocked version. My unlocked version does not support a number of AT&T's features I would like to have access too. I have read how to flash the Rom and I know how to do it. I downloaded a Rom which I thought was the AT&T stock rom but it was actually the same Rom I had the unlocked version. So when I flashed it it was the same as before. I think it is possible it flash the phone so that it is like I bought it from AT&T. I have seen people do this on youtube with their Galaxy note 10's. I am unable to find the Official Stock Rom or maybe I have and am unsure if it is the official one. So if anyone knows where I can get the dang official Rom so I can flash my unlocked phone and turn it into an official AT&T phone that would really help me. Thank you very much.
My Model Number is
SM-N96OU1
My Baseband Version is
N96OU1UEU4DTC7
My build number is
QPA.190711.020.N96OU1UEU4DTC7

in sammobile, you could find your "carrier" rom version as you want, which is U, not U1 (unlock version).
then use samfirm or frija to download the rom with max speed.

So If I want to flash it too the official AT&T I should look for SM-N96OU instead of SM-N96OU1, correct? I am nervous about bricking the phone. I have read that the AT&T version and the unlocked phones are exactly the same they just have different firmware. Is this true?

I'm looking to convert my SM-N960U1 (unlocked) to the AT&T version as well. I'm seeing the following as the lastest firmware I should be downloading to convert to AT&T. Can anyone verify this because the N960U does not have AT&T firmware available?
...firmware/SM-N960U1/ATT/download/N960U1UEU4DTC7/335086/
All the U firmware is the same. If you have At&t sim you can flash any Note 9 U firmware and it will provision to your sim. If you are coming from U1 you will need to do a factory wipe. Was your device purchased as unlocked or was it U?....
Oops never mind I see its unlocked.

For some reason i feel that Sammobile its more about selling firmware software to buyers of samsung instead of helping people take the best out of their phones. Some of use pay over the 1000 dollar for a phone and dont get easy help while samsung should atleast give us the freedom to get the firmwares for our devices for free. Sam mobile has ablot of information on their website,but ofcourse nothing for free. Even signing up their websites is an issue,and to get support thats another issue. So i most say Sam mobile its all about selling Samsung software,while you and me who buy the phones,not sammobile! Resell it back to us. Seriously its discrimination in my eyes. Maybe am wrong, but thats how i feel about. Now i dont know what business relation sammobile has with samsung,but i know the founder is not a. Chinese, but a Holland guy. Thank u.

Question Flashing Unbranded 998U1 FW on VZW S21 Ultra 5G Variant

Good morning
I'm looking for global FW and I can't seem to find one that has bootloader version 5. My VZW phone just got an update on Jan 24 and evidently updated the BL to V.5
The most recent SM-G998U1 firmware only shows bootloader version 4. Am I just stuck? Any guidance is way appreciated!
Not sure what you mean by global FW, probably unbranded US FW.
You will just have to wait until G998U1 FW with BL 5 is released. Basically stuck until then...

That's exactly what I mean. Thank you. Seems weird that a carrier is first to release anything!

BULH (G998U1UEU5BULH) has just been released standalone check SAMMobile for G998U1
G998U is for US carrier FW
G998U1 is for unbranded US FW.
Both are interchangeable for Snapdragon US S21 Ultras
My phone is AT&T but I have been using G998U1 for a while now.

Awesome! Thanks for the heads up!
I just posted a thread on how to carrier unlock the same exact phone and FW/BL you are using, this may also lead to possible BL unlock later on, but may help you for now if you just trying to use a different carrier. Otherwise, yah, you are stuck for now, can't downgrade the bootloader. (As far as I know of yet)
Thanks for all of the advice and insight. Mucho appreciado.
My goal here is to purely load the non-carrier specific FW while maintaining my ability to use VZW and still have mmWave or UWB support. Also, VZW removed the ability to do "calls on other devices" like a Samsung tablet. That feature was removed on VZW FW but worked fine on an unlocked Note 20 Ultra that I had a few months back. Loading this G998U1 FW should make it act like a direct-from-Samsung phone, right? I don't really care about an unlocked BL or unlocked SIM slot, at the moment, as I'm staying with VZW. Thanks in advance!

And just to confirm, we'd want the XAA version, yeah? That's the non-carrier-specific FW?

SamMobile has download speeds equivalent to dial-up internet, unless you pay them for a premium membership.
SamFW.com is fast and free

That is what I do, and I believe you are right. Other versions may also be same or may be just as fine, but go for unknown XAA regardless.

You are right, their free dl is slow, but the others dont have it yet, so if you need it asap, their dl is the best you can get as of today. I am sure samfw and frija will have it soon.

Incorrect. SamFW already has it. Do you really think that I would recommend a site without checking first?

Yes, they did already have it.
You wrote your post 20 minutes ago, while my post was 2 hours ago. And I checked before making my post, so you clearly did not check before making yours

Even if you're referring to your post from 10 hours ago:
Where you do think SamMobile and SamFW get the firmware from....???
They get it straight from Samsung's servers, using tools like Frija and others. So SamFW may not have uploaded it yet (as of the timestamp of your post from 10 hours ago), but if SamMobile already had it, then Frija definitely did - because that's always the first and earliest available firmware source, since it pulls straight from Samsung's servers
Thanks for everybody's help! I'm going to take the plunge here -- looking to download the modded/patched version of ODIN and flash this sucker. *fingers crossed*
If I flash this on my AT&T branded s21 ultra, will I lose any features?
This worked great on my VZW variant -> unbranded -- flash took about 3 minutes. I did do a factory reset prior to the ODIN flash just to ensure that Google or Samsung didn't have any weird reactivation-type lock on the device. Thanks again for the help!
As far as the Samsung "allow calls on other devices" option, that does NOT work on VZW, for whatever reason -- when I initiate a call via the S7 tablet, I get an error that essentially states that it "Can't Make Calls. Make sure that your phone and tablet are connected to the same wifi network." Huge bummer! I'll keep trying. I know that when I had an unlocked, direct from Samsung Note 10+ and the S6 tablet, this feature worked perfectly. Fast forward and I no longer have either device and it's not working. Any thoughts are welcomed!

I lost nothing featurewise - still getting 5G mmWave and the WiFi calling is working.
