Here's the situation:
I'd like to take advantage of the Samsung trade-in deal but want to buy the correct phone to give me the most options and i'm finding conflicting things on reddit and even here, can someone answer a few quick questions for me:
1) Can i START with an unlocked S8+ from Samsung and flash the TMO firmware if i want? Or any carrier firmware for that matter (selling purposes)?
2) If the answer is no, you can't start with an unlocked S8+, does that mean i have to get a TMO version of the S8+ to be able to flash the unlocked firmware and/or flash back to the TMO firmware?
3) Lastly; if i get a TMO S8+ and flash the unlocked firmware can i still flash the TMO CP to get 256 and MIMO? I did that with my S7 Edge however i started with a verizon version which was already unlocked - flashed unlocked firmware but TMO modem.
3b) I also saw someone on reddit who said they bought the verizon version, flashed the unlocked, then flashed the tmo.
I appreciate the clarification, there are just so many threads and a lot of different answers it's hard to sort through them.
Thanks in advance.
I have the same question. I ordered my wife a T-Mo S8+, because she doesn't care about unlocked/bloatware, etc.
I ordered myself a US Unlocked version, but now I'm.wondering if I should've ordered a T-Mo version.
Couple reasons:
#1 T-Mo version has RCS and video calling. Not a big deal, but cool nonetheless. Apparently GearVR doesn't work on the unlocked version?
#2 The unlocked version only comes in black. I have a couple options with the T-Mo version and could always flash the unlocked software.
#3 Some people have had issues flashing BACK from the unlocked firmware to T-Mo, so if I want T-Mo firmware on my unlocked version, will I have issues flashing it?
I don't really care about colors. Black is fine. And if I can freely and easily switch back and forth between T-Mo and unlocked firmware on either version of the phone, then it doesn't really matter which one I get. Until I know which firmware works best for me on T-Mo, I'm not sure which version I really want to use.
They fixed the GearVR on the unlocked versions; of the 1000+ posts i read i did see that.
Also, i did find this thread but haven't had time to go through it all:
https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487
Based on the title, i would ASSume you could do whatever you'd like. I don't care about RCS or video calling so that's not a big deal to me. I decided to take advantage and nabbed the unlocked version, it was the cheapest and since i can probably find a way to flash whatever i want on it i took the risk. I have a couple old phones that getting $200 in on trade is worth it, i went with the S8+ and will probably do it again using my wife for the S8 trade in. Decide which device i like the best and sell the other.
The trade-in was the main incentive for me too. Coming from Nexus and Pixel I'm used to unlocked devices as well.
And I've been pouring over threads today, but some threads are 100+ pages long, and just too long to read or even search through.
Usually the community finds a way with flashing firmware so i'm confident. I'll come back and update this thread when I get it, the only thing I would like to do is flash the T-mobile CP modem for 256 QAM and 4x4 mimo. Other than that, Unlocked firmware all the way

Same here. I received my S8 plus unlock version. I would like to convert totally to t-mobile. Instructions so confusing though.

All you need is the firmware files (BL, AP, CP, and CSC_OYM for new carrier flash, CSC_HOME for manually updating same carrier firmware) for the version you want to move to and the modified odin (prince comsy). A quick search will turn up all you need here on xda. Just like the snapdragon S7 and edge, changing which carrier/unlocked software you have is just a 5-10 minute odin away. All versions are compatible regardless of which carrier/unlocked software you start with. Ignore all of the "how to change to XAA" etc. Just find the modified odin and firmware you want to use and flash.
EDIT: To clairify, all snapdragon software versions are compatible with any snapdragon S8 or S8+.

There's no longer a need to flash the TMO cp. I have flashed the unlocked software on my TMO S8+ and unlike the S7e using the unlocked firmware, CA, 256QAM and 4x4 all work fine. The phone enables these things based on the sim inserted. I did a test with my wife's S7e (unlocked using TMO modem file) and my S8+ side by side and speeds were identical, and my S8+ reports CA using bands 2, 4 and 12. The S7e on the unlocked cp (modem) would not have CA and have slower download speeds.
The only thing you lose is the video calling within the phone app (same as the unlocked S7 and edge) when flashing the U firmware to the S8. But unlike with the S7, since you no longer need to flash the TMO CP file to get 4x4, CA, etc, you can now take OTA's for the unlocked version and do not have to manually flash the newest firmware in odin.

Infinite Thanks! So based on your post, i'm not going to do anything. I hope your message gets out there because there is a lot of confusion on various sites including Reddit about the CP modem with the S8/S8+.
That's great news.

Thanks. So finally i flashed tmobile firware on my unocked version s8+. Now i have video calling enabled and also tmobile logo while boot up. As u said i have my end results showing TMB/TMB/XAA NOT TMB/TMB/TMB. But i guess from your post i dont have to worry about it. And also they got rid of enable VoLte toggle but it can be enabled with nova launcher not a big deal.

Are you saying that you can't accept OTA updates if you flash a carrier CP with unlocked firmware? Or are you saying that accepting an OTA on unlocked firmware will overwrite the carrier CP?
So I just bought a Verizon Pixel XL off ebay with the intention of using it on T-Mobile because I was under the impression that taking it to T-Mobile was no issue and would be no different than using a google store one on T-Mobile. Although I am reading some concerning threads about the bootloader issue. If this phone happens to have 7.11 will I be unable to flash the T-Mobile factory image onto it? Or is there really no benefit in doing this anyway? Do I and will I be able to flash at least the T-Mobile radio over to it?
Then if it is before 7.11 and I unlock the bootloader right away can I keep it unlocked even if I play around with images and stuff such as trying out the O beta? or do I have to avoid Factory images once its unlocked and only use custom roms?
Thanks in advanced!

Only thing that matters is if the origin of the phone is Verizon or Google.
If the origin is Google you can install the Google factory image and use it on anywhere, unlock the bootloader, root and have a grand old time.
If the origin is Verizon you are relegated to the Verizon image regardless of where you use the phone, no flashing for you.
Compare the build code of your phone to the build codes on google factory image website and you will know what you have.
good luck

Well this was a display model I guess, no specifics on what kind of store but its listed as being a Verizon model. So I may be SOL. As far as working on T-Mobile if that is the case are there any downsides to using the Verizon model aside from flashing?

Verizon model is fine for what the phone is.
You shouldn't have any issues using it on T-Mobile USA . Verizon phones are sim unlocked . The only thing with the Verizon version is that if it had the update where they don't let the bootloader unlock then you can't unlock it and root. Besides that you can use it on TMobile as a regular Google phone.

This is partially false, I'm using a Verizon pixel XL on TMO and when I dropped out of beta, Google rolled out the TMO branch to my phone.
If you can depixl8 it and unlock the bootloader, you can flash custom Roms or the factory images to your heart's desire with no issues. Just never relock the bootloader, since it won't be able to be unlocked again(if it truly is a Verizon pixel XL)

You can sideload updates to a locked device so OP could sideload a current ota from tmobile. It can in fact beneficial to run the tmobile software on tmo because of optimizations for network connectivity
If you haven't updated it yet and its version is older than last November, you should be able to unlock the bootloader. Once it's been updated to a newer version, it can't be unlocked.

I guess that'll be the big question. If the phone was only a display model since it was released. I wonder if the display models get the updates pushed automatically... I will find out tomorrow.
Well the phone came with 7.1.2 so no fun for me. Thanks for the info from everyone.
Very interesting, I stuck a T-mobile SIM in it and I can now switch on OEM unlocking. It was greyed out before I put the SIM in.

I have not I will this evening or tomorrow though. I was just under the impression that all Verizon Editions had that switch disabled no matter what SIM card went it. As I stated before this was a display model, I got it for next to nothing due to very minor screen burn from the demo mode, I can barely see it so i'm good with what I paid. So I wonder if display models weren't Verizon models? Or maybe this was a third party Verizon store and not corporate. Either way is there anyway to tell which one it is? The SKU on the back is G-2PW2100-021-B and it has build number N2G47E on it, which is not the verizon build I don't think.

Google points to that being a Verizon SKU. But with the build number being non-Verizon, you might be able to unlock it.

Hi, I was about to buy Google Pixel XL off the eBay how can I tell if its Verizon phone or Google phone? I asked two sellers, they didn't know if it was Verizon on Google phone, they are just selling as Unlocked GSM , I never bought Google phone so I'm very new to it, per my understanding Verizon phones wont able to have unlock bootloaders? and Google phones will do? also Google phones can work with Verizon and GSM phones without any issues or they are only good with GSM?
you were saying something about build id to check
https://developers.google.com/android/images
I went to this webpage but I dont see any differences in model # for both ver?

I literally just did this 2 months ago. Got a pixel xl and it was a verizon phone but I have Tmobile. The phone can be unlocked, it can be rooted, it can be rommed, yes it can! Mine came with 711 or 712 cant remember but whatever doesnt matter. Just follow the guide in the other thread by @Homeboy76, it's a GREAT read and tutorial. It will put you from stock nougat to stock pie, but afterwards you can go to nougat, oreo, or pie. I know because after I did it, i went to an custom rom, then to a custom oreo rom, back to stock pie, back to custom pie lol. I would put a link up to the thread but idk how to do hyperlinks lmao, i skipped that day of school.
I've read that the Galaxy S9 hardware is identical for all carriers in the USA.
If I bought a factory unlocked Galaxy S9 can I flash it to the carrier I am using (Verizon, Sprint, T-Mobile, AT&T) to enable carrier specific software and features? Can I flash it back to the unlocked firmware?
I already see a thread about flashing the unlocked firmware to carrier models so I am assuming there are no issues there.
Can one carrier model be flashed to another carrier model?
No, bootloaders are different, with the S7 there was an unbranded U firmware that was compatible with most of them, unlocked firmware will be that one for the S9, but no you cannot just flash different device firmwares to the wrong model
I was able to flash the ATT rom onto my Verizon S9. I got a VZ s9 from work but I'm on ATT. For the most part it's worked great, I had done the same thing previously with a Galaxy S7. I say for the most part b/c I am on here tonight to post a question myself about the fact that I'm getting a delay with MMS messages. I imagine it has something to do with the APNs I have setup, but I can't seem to figure it out.

Did you have to flash to the U1 software first?
I do think that is what I ended up doing... tried to go directly first and it kept failing. Got fed up and decided to just try and put the bone stock rom on it, and that went on really easily.... so after using it like that a few days I tried to drop the ATT rom on it and it worked without issue.

Yes, but you need to go to the u1 firmware 1st then to the other carrier firmware. Also make sure you avoid the newer firmwares with the new bootloader, as the unlocked model and certain carrier models don't have the new bootloader.

That'll be why I still thought that then, coming straight from the S7 > S9
Had many members flashing the wrong firmwares thinking they could do that and bricking their S7s / wondering why ODIN failed

I tried downloading vzw firmware G960USQS3ARI6 to my unlocked sprint s9 and still not vzw flashed. want to do this so can have voice over LTE. Any other steps im missing? flash went through but still sprint
As soon as Firmware ver. 3 came out for the G960U1, I was able to flash it to my Sprint G960U and finally have VoLTE, WiFi calling and stable LTE for MetroPCS. Used samkey to unlock it from Sprint. My phone is actually performing much faster without all of Sprint's bloatware hogging my RAM and storage space. I can confirm that OTA updates still work the same...I received September's security patch (current) with no problems. Device is still official status and Knox hasn't been tripped.
A lot of people think you can just flash the carrier firmware of your choice and boom, it works...I had the same thought process....that's not the case. You have to make sure that there is a matching firmware version for the carrier you want to flash to, as well as make sure the G960U1 firmware version (the unlocked version of the S9's software you have to flash first before even carrier flashing) is the same version of what is installed on your phone now. It's easy ya'll......just READ lol.
I'm in love with my phone again thanks to XDA. ?
HAPPY FLASHING!

I can confirm that OTA updates still work the same...I received September's security patch (current) with no problems. Device is still official status and Knox hasn't been tripped.
A lot of people think you can just flash the carrier firmware of your choice and boom, it works...I had the same thought process....that's not the case. You have to make sure that there is a matching firmware version for the carrier you want to flash to, as well as make sure the G960U1 firmware version (the unlocked version of the S9's software you have to flash first before even carrier flashing) is the same version of what is installed on your phone now. It's easy ya'll......just READ lol.
I'm in love with my phone again thanks to XDA.
HAPPY FLASHING!

Hi, I got one unlocked G960U1(G960U1UES3ARI1) and downloaded new fireware(G960U1UES3ARI1-SPR) from sammobile, but after flashed SPR ROM successfully, the info on the phone still shows XAA, anything I missed here? Thanks!

Well first off, you have the unlocked phone. I don't. My G960U is originally from Sprint, so I'm not sure about carrier flashing regarding the G960U1. I thought it was supposed to provision itself after you put the sim in, and the associated carrier apps will download since it's the unlocked model...but I may be wrong...

I've read that the Galaxy S9 hardware is identical for all carriers in the USA.
If I bought a factory unlocked Galaxy S9 can I flash it to the carrier I am using (Verizon, Sprint, T-Mobile, AT&T) to enable carrier specific software and features? Can I flash it back to the unlocked firmware?
I already see a thread about flashing the unlocked firmware to carrier models so I am assuming there are no issues there.
Can one carrier model be flashed to another carrier model?

I know so many people have already answered your question from some saying No to others saying Yes but you need to Install U1 first and Bla Bla Bla.
I want to give you one specific answer: With S9 you can any Carriers firmware you wish or even Unlocked phone's firmware. You will never have any issue. And you don't ever need to flash U1 or something else before changing carrier firmware you can Flash from ATT S9 firmware to VZW S9 firmware without any issue. You can also flash from U to U1 which is from Carrier specific to Unbranded/Unlocked but only hiccup is original Odin will give you SHA-256 error, which is normal because you are flashing U1 firm to U device or vice versa. This error can easily be resolved by used Patched odin that disabled SHA-256 check. And trust me you will never have any issue.
You will never want to do this but I have gone as far as mix-matching U and U1 firmware together as well. Like flashing AP, BL and CP of U device but flashing CSC of U1 device. and it still works.
hey there, a little late to the party, having trouble with going from a Verizon to a Sprint, even by way of U1. I can't get any of them to work. And I've been told I have to go from VZW to U1 before I went to Sprint. Is that not the case? I'm having a hell of a time getting anything to flash, everything fails.

well, I tried to load the Sprint image from the VZW, no dice. It said it passed, but upon reboot loaded up the old Big Red (even with the Sprint SIM in it).
Anyone have any ideas? This is driving me insane....

1.) - Yes it is that simple and it does work. I had done it with the U1 firmware and had no issues. If you want to ensure full compatibility (and video calling) then you will wanna consider flashing the Tmobile carrier firmware. Flashing carrier firmware onto the phone will not have any impact on the network/sim unlock status (in case if your wondering).
2.) - You will have to ask the carrier your going to use in Asia if it will be supported. Since the unlocked model has no sim/carrier lock on it you can use it with any provider that supports the phone.
3.) - Yes and No, depending on the carrier. Tmobile has been the most compatible with BYOD devices so yes to most of that. AT&T on the other hand not so much so, as they only provision things like WiFi calling, VOLTE, etc. on phones they have sold. Some people have tried to find work arounds to this AT&T restriction, so YMMV.
In Tmobile's case if I remember correctly WiFi calling should work just fine and VOLTE will. You may need to setup the APN manually, or at least make sure it is set up properly. Another option (and one I did to get video calling to work) is flashing the the firmware from Tmobile for the SM-N975U to ensure full carrier compatibility.
What do you mean full compatibly video call, isnt video go with facebook messenger or depend on apps?
I don't have to root in order to flash, right?
Is there any current issues that I need to know?
Is it worth get 5g at all?
Is there any guide or video guide to flash tmobile carrier firmware to note 10 plus unlocked? Please answer asap so i can purchase phone soon

Hopefully this will clear up any misunderstanding..
My reply was referring to carrier features and nothing more.
When I says "full compatibility" I mean any specific customization or tweaks the carrier makes to the firmware they release for the network they run. These tweaks would not be fully (or mostly) present on the U1 firmware. For example U1 firmware may not get the best speed or signal strength as opposed to the carrier released U firmware.
When I say "video calling" I am talking about starting a video call from the dialer app (same one you use to dial a random number on the telephone). This would not be present on the U1 firmware.

No.. but I would suggest that you do some google searches and read up on how to do this. This way you have an understanding on what you will need odin for and how to use it.

IMHO in the USA I wouldn't just yet.. Not unless you want the shiny shiny to show off to your friends. It's not widely available and once it is I would still wait for them to work out all the kinks before spending the extra money. The LTE speeds I get as it is are sufficient enough for what I do, but eventually I will end up getting 5G after it gets fully released and the carriers get it stabilized.

Yes tutorials and videos are on the internet.
I would encourage you to put some effort into finding the answer. I will tell you that the steps to do this are the same for the S9+ and a person was just recently discussing flashing 975U firmware to the 975U1 firmware on this forum.
I wonder if this video good idea to follow

It is pretty decent.. but here's a few more things you will want to do.
If you have a google account on the phone already be sure to factory data reset it to remove FRP lock.
If not already mentioned in the video use the CSC_*** file and not the home_csc file.
Flash the USERDATA file included with the tmobile firmware. You can easily see where to place the USERDATA file in tge odin flashing tool.
After you get done flashing the phone be sure to factory data reset it to ensure everything works (OTA, etc).
sm-g975u unlocked att phone wanting to change to tmobile. I have a tmobile sim and had originally plugged this in. The phone works fine but I recently noticed it has no Ota updates occurring. I would like to load tmobile firmware on it to enable some of the tmobile features as well but primary concern is ota updates.

When I try says fully updated when I put it on samsung switch it says fully updated
Can this be done?
What firmware do you suggest?
Csc *#272imei#(may have that wrong) but is recognized and does work not sure when and what to use here, many options.
Also, not sure of the answer here, but if I run an update or csc change (the phone is unlocked) would it require me to unlock it again for any reason?
I am trying to get the phone close to a tmobile if that is possible
Thank you in advance if i need to give more info please let me know.
Download the firmware of your current network and flash you will begin to receive updates. However you can also flash the unbranded one which is G975U1 and you will still receive updates too
Can you give directions on how to get the firmware for the current network and how to flash the phone? I have an SM-G975U that is on SPR that I need to get to ATT so it will get updates from cricket. I have found a lot of materials on the internet and not a single one shows all of the steps clear enough for me to risk blowing up my phone. I have found the SPR files and TMK, and USA, and TMB, but no ATT.
