Just got an Unlocked S10 for use on ATT network and am debating which firmware I should load. I imagine the answers are already here on this forum but frankly my head is spinning going through the various threads.
With Carrier (U, not U1) firmware, I've read that the carrier specific firmware and bloatware will load based on SIM. I'm coming from an S7 so this is new to me. So what's the difference if I load VZW firmware rather than trying to track down ATT firmware?
Thanks!

If it's a u model never been messed with and properly unlocked it should load carrier based bloat and services based off the sim inserted. If you see multi csc or oym yes you should he able to load Verizon Verizon firmware and then it should repersonalize based off sim inserted. S8 and up all the us based u models are identical hardware. Software is only difference. I don't know the exacts on doing us models. I smartened up and got F models or imported snapdragons due to unlocked bootloaders. But I did have a u model s8

i have an unlocked 920t (t-mobile) on att network. should i be using the att section for rooting and roms?
No. Roms are based on your phone model. Stick to the TMobile forums. I know with the S4 the international roms are generally compatible as well so you may check in the General S6 forums, too. Most custom roms list which models are compatible in the OP.
Besides, you won't find much here since the att phones have locked bootloader and no root currently.
great, thanks.
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?

There are multiple sections, but I believe you need to look under: Flashing Standard Firmware, but do ask, just in case.

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.

Hi Everyone,
I've searched and could not find a clear answer, and am hoping someone can help.
I just purchased a US Samsung Note 8 (SM-950U1), my question is, is it possible for me to install the G955W (Canadian) firmware on this device?
For Canadian users is anyone currently using a US Note 8 (SM-950U1) Factory unlocked?
Thanks.
Made a typo I meant can I flash SM-N950W Canadian firmware to a SM-950U1 Factory unlocked Note 8
Thanks,

not yet, North American models are all Snapdragon with locked bootloaders. If someone finds a way to unlock the bootloader then you could get a flashable zip version of a Canadian ROM and use that but as far as I've seen nobody has been able to do much with the Snapdragon variants yet.
I have been reading the s8 plus thread where users have flashed the s8 plus Canadian (sm-g955w) firmware to the Us s8 plus (sm-g955u) is it not the same process?
Thanks for your help

If you follow the s8 + guide...if available it would be the same for u...I am working on a guide for carrier switching but it is for U.S. snapdragon models...but it uses the Canadian XAC home_csc...I say pm the poster of the s8+ that you mentioned for details and then flash at your own risk....you can always flash back to your original....before you do, though, insert your Canadian carrier SIM and see if you can activate it...when I was testing the carrier switch there were options to change to Canadian csc's....good luck
Any update? I also bought my note 8 from USA. With the US firmware, we do not have access to certain features like VOLTE or caller ID and spam protection.
Check out blue fox's thread. I just flashed US firmware on a Canadian unlocked XAA device(not sim locked to Rodgers, bell etc). long as your flashing stock Samsung firmware, youll be fine. The Canadian and US Note 8 phones are basically the same.

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.

So i bought this phone here in the middle east and i noticed that the firmware is from USA (Sprint). and i feel that the phone is used or refurbished. My question is:
1. Can someone easily modify the RTN so that the reconditioned status will be "No" so it would look like its not a refurbished one?
Also i noticed that samsung pay is showing deals from USA, my second question is:
2. How to change the country of samsung pay to a middle east one where im currently residing?
Edit: I have a SM-N960U Phone if that helps.
Edit2: Also why its not updating to Android 10?

1. I have no idea about this. sorry.
2. no, you cant. you have a Sprint version so you just can use samsungpay in US according to your phone's CSC (if your phone's knox hasnt been tripped, ofcouse).
2bis. the U version cannot update to android 10 by OTA. you can use odin to flash the latest firmware to your phone. Since you're living in middle east so i suggest using the U1 version's firmware to get rid of all Sprint's bloatwares.

Hi. Thank you,
i checked the warranty(vol down+power+bixby) and it showed 0x0 so im good on that part. but i can still use samsung pay using my middle east credit card right? or totally not at all?
i checked sammobile site and there are lot of U1 firmware variants it seems. should i just choose anything except for the CDMA?

I have the same model n960u from verizon and i am in middle east too.

https://www.sammobile.com/samsung/g...SM-N960U1/AIO/download/N960U1UES4DTD1/338195/
If you want everything work in middle east then you better sell this model and get international model N960F dual sim.
But in my opinion N960U is much more better because it has snapdragon 845 SOC chipset with adreno gpu its very powerful for gaming and battery efficient
and N960F has exynos with mali gpu and it's not that good as snapdragon.
And also thoisands of users has screen discoloration issues "hardware failure" with exynos model after android 10 update.

Not quite true about these things:
- samsungpay: here in asia, US version N960U can use sspay with some US banks' cards, ex: citibank credit card.
- screen discoloration issue: many Snap version phones have that issue too afaik, so i dont think its chip related. But yeah, the cause is still unknown.
I do agree that snap version is more powerful than exynos one.

It doesn't matter it's just csc code for who use American sim card.
If you use this phone non american sim it will use xaa unlocked csc code by default no matter which firmware csc you flash
They all comes multi csc firmware.
I recommend you to wait until next week because there will be new updated firmware available oneui 2.1 update with tons of new features from note 10.
Tha firmware i gave you the link earlier is oneui 2.0.
