Unlocked S8 -> Tmobile - T-Mobile Samsung Galaxy S8 Questions & Answers

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.

Can someone provide a link to a thread for flashing the Unlocked s8 to T-Mobile?
Thanks.

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.

I believe you will have wifi calling and volte but not 4x4 MIMO and 256QAM. i think MIMO is activated in the modem itself.

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.

Thanks Peeps!

Looks like it i got the verizon variant and ive downloaded the xaa rom which i believe is the candian one and it worked but didnt have any of the features like volte and wifi calling so i just now flashed att firmware and it worked flawlessy so yes it works!! no root no complications

We will need eng kernel before that happens. I'm sure it will be doable in the future, not now though.

So if I flash AT&T firmware on Tmobile Note 8, it should work fine on AT&T since there's no Tmobile Unlock App in it? Right?

Yes...if you look into the s8+ forum for carrier switch there is a guide that should also work for note 8...the main focus is to change the csc...however, you may just be able to flash the ATT firmware and it work when you put in the ATT SIM. It may be better to flash the unlocked firmware first...and then to att...but to get the device to be csc ATT, instead of ATT, ATT, TMB, You may have to follow the S8+ guide...
So try the easiest first, flash ATT...If activation does not work, flash Unlocked then ATT, if that is no good...follow the S8+ guide with Canadian firmware to change csc code of device to ATT...you might pm the op of the S8+ guide about what Canadian firmware to flash to change the csc...I am going to make a guide for us when I have a chance to test it myself...if just flashing to AT&T works...awesome, good luck
Oh yeah...the device must be unlocked first to change carriers...you can get it unlocked by T mobile or by paying for it

Flashing T-Mobile Firmware to Unlocked Version S10e

So I'm planning to buy an unlocked S10e from Samsung's official site, but I've heard that on the unlocked versions you get slowest updates, no RCS, no wifi calling, nor VOLTE. I've used Andriod for years but I've never used any other samsung product besides my Galaxy S3. I've heard you can flash firmware but I needed some questions answered. Would this break anything like knox? Would I get updates normally ? besides bloat any problems with doing this ?

No, unless you like using mobile hotspot for free (if that's still a thing on the unlocked firmware).

Yes, you will receive updates from whichever firmware provider you install. If you have Samsung's unlocked then you'll get it directly from Samsung and if you flash T-Mobile, for example, then you will receive updates from T-Mobile in the future.

Other than possibly having to pay to use mobile hotspot, as addressed above, I don't believe you could introduce any other issues not mentioned.

Thank you. This is really helpful. I believe that the hotspot should be free on T-Mobile ? (My LG V20 can use it free). Also do you have a guide for flashing the T-mobile firmware ?

At&t is only carrier where wifi calling and Volte won't work for unlicked units. It has to do with the imei.

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.?

S10 U firmware vs. U1 question re carrier specific optimizations

I read on another forum that does have the technical talent that XDA has, that if I have an unlocked S10 with a U firmware and start on T-Mobile as an example and then restart the phone with an AT&T sim card that the phone will reconfigure itself for AT&T including the built in apps.
Is this true?
Thanks in advance.

Yes, Samsung uses multi-csc firmware on most devices for a few years now. If your going to use att for service though i would recommend flashing there specific firmware they release which is more optimized. There are a few threads with links to the files. And if you switch away from att later switch back to any other U/U1 carriers firmware.

NOT TRUE WITH THE S10 from a US CARRIER!!!
Each Firmware is Carrier specific if the phone is locked to that carrier!
Once the phone is unlocked, you CAN flash the USC Firmware, which is the Unlocked MultiCSC and AUTO SWITCHING for most USA carriers....
The only G973U phones that do this out of the box are the UNLCOKED phones from Samsung. They have a CSC of USC.
ALSO, good luck finding "AT&T Specific Firmware", as it is nearly impossible to find, the USC firmware hass all of the carriers bloat built in as well. and it switches it out automatically when you swap sims....
AND, if you do install the ATT specific firmware, you will just have to flash it again if you want to switch to another carrier and actually have their features and apps! SO, Just use USC firmware!

I was saying to use att firmware because its been agreed upon without it you wont have that good of signal. Blame ATT for being a**holes like that. Just because you CAN use other firmware dosent mean its the only or best way.

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
