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?

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.

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!

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 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.

I purchased a Samsung S7 on Amazon, and it was listed as a G930V. However, when I received it, I was disappointed to see that in "Device Info"... it lists it as a Samsung G930U.
From what I understand, this is indicates Unlocked Firmware install, which will prevent me from using Verizon's Visual voicemail and also be unable to use the built in Video calling feature, where you can video call anyone in the Verizon Network.
What I don't get, is why the back panel of the phone has a Verizon Logo, even though apparently it is unlocked. I thought all Verizon branded phones, have the G930v firmware?
Anyways, is it possible to flash the phone to G930 firmware, so I can use the features I want to have access to? Or is it recommended I just return this item and try and buy another G930v? Does anyone have any detailed instructions on how to flash to G930v?
Interestingly, when I checked the IMEI online... it lists the device as a Verizon G930V. I guess someone has previously flashed these to U from V?
ETA: Are there any benefits to sticking with Unlocked firmware? Are there any advantages of G930U over G930v? I know the G930v comes with a bunch of bloatware... but wondering if there are other things that VZW's firmware might handicap?

3 weeks late but here are my insights. U firmware has less bloatware than the VZW branded firmware. In general, most people prefer the U firmware over their branded firmware unless, as in your instance, there are certain features only available in branded versions. My guess would be that yours was a VZW that was flashed to U. In all likelihood it shouldn't be too difficult to convert back to VZW, if that's your preference. You'll need to familiarize yourself with Odin flashing and the particulars of matching bootloader numbers for firmware to flash. For an example see link: https://android.stackexchange.com/questions/202491/what-do-the-numbers-and-letters-in-the-samsung-firmware-mean
Hope this helps ...
I got Note 10+ 256gb unlocked version from Samsung. Planning on using it on Tmobile. Do I need to do anything specific to make it more compatible with Tmobile. I've currently unlocked s10e on Tmobile and overall network coverage seems bit subpar compared to Galaxy S8 that I purchased from Tmobile.
So I'm just curious if I need to do anything for Note 10+ ince I get it, to make it more network friendly.

Download the tmobile firmware from sam mobile and odin it to your unlocked.
I googled it but didn't have luck. Any chance there is a link to the T-Mobile firmware?

It's not up on Sammobile yet...
But it is on samfrew

What about for the 512 version unlocked? Can use same as 256 unlocked?
And is it recommended to flash the firmware (T-Mobile in my case too) right out of the box or do you have to put your old sim in from your previous phone first, then setup your gmail acct and let the sim reach the T-Mobile network?
Never had unlocked phones so this will be a first, hence the questions...

It doesn't really matter. The storage size doesn't affect the firmware. It's all the same.
Flashing the carrier firmware will factory reset your device, so I wouldn't waste time setting it up first. Just put your SIM in and let it provision for T-Mobile. It happens automatically so there's nothing you have to do. Then flash the firmware with ODIN.
Just research and make sure you know what you're doing before flashing. ODIN is fairly fool proof, but it's still best to know what you're doing first.
Add each file to it's respective field in Odin v3.13.3. Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data.
I thought you can flash without messing with your data.

Technically you can flash without messing data but will be difficult to identify the reasons if you encounter any issues after that. So its better to flash it now itself when its freshly out of the box
I was going to update the Unlocked firmware via OTA software update. Once I receive the update I will then flash the Tmobile firmware via Odin

Just received my unlocked Note10+ 512GB an hour ago and, as was the case with my unlocked Note9, it works great out of the box with T-Mobile and Mint (a discount reseller). No custom flashes needed unless you want the TMO bloatware. I would leave it as-is and just download the respective carrier apps individually. Love this BEAST so far! :good:
I bought the note 10+ and i'm on the tmobile network. The only issue I'm having is VOLTE. To my knowledge VOLTE should work. Can anyone confirm this?
Hi everyone,

Even though it is unlocked, i can see the SM-S901U does not support 2 5G bands which are used my in country (unlike the generic unlocked SM-S901U1). My question is that,
1) Since the s22 is basically from samsung, with the carrier models having control over the software, will i be able to flash to the generic unlocked firmware and model SM-S901U1 and get support for the other 5g bands too (i see the generic unlocked version SM-S901U1 has the 2 other bands that i need)?
2) Will the hotspot work and will i be able to recive OTA updates?
3) And the main question, will i require an AT&T SIM for the flashing process?
I was digging around the ultra thread for some info:
OTA and Non-OTA Firmware for S22 Ultra SM-S908U and S22 Ultra SM-S908U1 Versions
See Post #2 and #3 for the Links to the Firmware All of the firmware posted here can be flashed on any U or U1 Device. Each of the firmware's are NOT carrier dependent and only has carrier labels listed in order to have an idea if you might get...

If someone can help/guide me, i'd be great!
Thanks and Cheers!
1. You will be able to flash s901u1 firmware (you will need a patched version of Odin to do so) but it still will not have the 5g bands, it's a hardware thing.
2. Hotspot will still work and you will be able to receive OTA updates when on s901u1 firmware.
3. No you will not, even when the phone is locked you will still not require a sim

Thanks for such a quick reply
I had thought that the bands were locked via firmware (was hoping that samsung gave control to the carriers to control the bands via software). Sadly that doesn't seem to be the case
Since the s901u1 has those bands available (i checked here: https://devicebeast.com/devices/samsung-sm-s901u1-galaxy-s22-5g-uw-dual-sim-td-lte-us-256gb), i guess that will be a better buy for 5G.
I have an SM-S901N, unlocked snapdragon from South Korea, bought it last summer and rooted successfully using the method here. I've been running rooted, updating periodically with odin, everything works just fine. Except...
I'm in the US and use Verizon Wireless. The two features I miss: wifi calling and visual voicemail. These are both only available with the VZW firmware.
The U1 is also an unlocked snapdragon. Can I flash the U1 VZW firmware on my N and get these two Verizon features? Even better, can I use the HOME_CSC from VZW and change the CSC without a wipe? I've seen mixed info on whether you can successfully change CSC using odin without wiping, and have it stick. I assume the Verizon-specific features will require the CSC to be set to VZW in addition to everything else.
Your phone will die if you try
