Hi XDA,
I am currently on a T-mobile contract, but I will move to a different country for business purposes.
I know how to do the device unlock (thanks to youtube), but I was just thinking of different issues that
might come across when using different GSM network.
my device is rooted, running custom rom with T-mobile radio.
my questions are:
1. even if i unlock my device, shouldnt i flash a different rom that is compatible to other networks? (different radio too?)
2. could i use the roms and radios that are used in international version?
if the process is more complicated than I am thinking, could someone light me up?
Thanks in advance.

Never flash anything from an international model as you will brick your device.
Hello, I am soon to be new to the one plus scene, and had a few questions.
I got the factory unlocked 7t and plan on using it on tmobile. Am I going to have rcs messaging? Will it be limited in any way? Also I have read that you can flash to international from tmobile but can you go the other way? And final question going either way does it require root or anything or because they are stock images they work fine?
From what I can tell from where I purchased it says HD1907 which is the tmobile variant(or should be?) Listing and reviews say confirm getting the HD1907, and its factory unlocked without branding. Can it be branded? And I should be fine and able to go to international/de-brand if I decide to later?
Welcome to the OnePlus 7T, it's a great phone!
I suggest reading through this guide to flash from T-Mobile to Global: https://forum.xda-developers.com/oneplus-7t/how-to/guide-t-mobile-brand-conversion-to-t4019495
It will walk you through the entire process of flashing your phone and (if needed) rooting it as well.
Personally, I'm a big fan of the All-in-One Tool found here: https://forum.xda-developers.com/oneplus-7t/how-to/tool-tool-one-driversunlocktwrpfactory-t4103515
It does just about everything you could need in terms of flashing, rooting, returning to stock, etc.
No matter which guide you choose, both forums are very active and should be able to help you if you run into any issues.
In regards to the RCS messaging, you should be fine but don't hold me to that. I typically use Google Voice but I know that Google Messages supports RCS on T-Mobile.

First thanks for the quick response, as a past dev im familiar with xda and have been looking through the 7t section including those and im starting to getting familiar. Thanks for the recommend!
I suppose the question I still don't get is the listing is for a tmobile unbranded so does that mean its on global or not? is it on us, not global, but just not branded but other wise 99% similar to branded just lacks carrier apps? Is there a step in between carrier branded and global? Does tmobile varient + unbranded just means it has the straight from OP firmware? If thats the case does that mean it can accept the tmobile branded firmware? I know everyone is like go global it seems but just for the sake of understanding I want to know since its tmobile varient hardware can it go back from OP updates(if thats what its on) to tmobile? and still be bootloader locked?
seems like there is several steps
carrier branded > carrier unbranded(straight from OP?) > global
However the update on OP's site doesn't list a different global download? How do global users get the update? or am i missing that theres a us site section and a non us site section?
There are a few definite ways to find out:
Model Number: the T-Mobile version is HD1907. I have the International version (HD1905) which has dual sim slots (the T-Mobile version only has 1 sim slot available)
Is there a T-Mobile splash-screen
Are there any T-Mobile (pre-installed) apps
If you have the T-Mobile version, it will never have the original OP software unless you flash the International ROM.
It sounds to me like it's a T-Mobile version (HD1907) that's been unlocked and (probably) flashed to the International (global) ROM (which will get you the official OnePlus software as it comes without the T-Mobile carrier bloat, which is really pretty minimal. I think it was 2 apps when I had the T-Mobile OnePlus 6T).
If you decide to re-lock the bootloader, I'm almost 100% sure that you must be back on the original software that the phone shipped with. So if it's a T-Mobile version, you must flash the T-Mobile ROM before you re-lock the bootloader.
No matter which software you have, it's really pretty easy to go from one to the other, especially with the All-in-One tool.
Personally, I prefer the International ROM (or their Beta Channel) because of faster security updates.

There are essentially 3 ROMs direct from OnePlus that you could flash (aside from the T-Mobile version)
HD65AA Global (which is one I would recommend)
HD65AA India
HD65BA Europe

So as long as it is infact a HD1907 I can use the builds here to go back to this models stock and then bootloader lock? would this be the best way to do so?
Edit: so the about info says HD1907 it didn't say tmobile when i started it the sim tray hold 1 sim. (just arrived) so I should be able to put it back on tmobile branded and lock the bootloader yes? I didn't actually confirm that its bootloader unlocked but im assuming since about info says its tmobile but appears to not be tmobile branded.(unlocked bootloader is only way that could all be true) The packaging was all completely sealed which is why im just a bit confused still as how it can be a tmobile variant but not be tmobile branded but also not modified outside of the factory?
so it looks like its 10.0.10.HD65AA rom, model HD1907, device state locked. so to go back to tmobile stock would I have to unlock? then do something like in this guide https://forum.xda-developers.com/oneplus-7t/how-to/op7t-t-mobile-unbrick-tool-to-restore-t4004005 ?

Just wanted to say thanks for the info! I was able to unlock bootloader(not sure if i needed to but did) flash the tmobile branded from https://forum.xda-developers.com/oneplus-7t/how-to/op7t-t-mobile-unbrick-tool-to-restore-t4004005 after doing that I looked in bootloader and it says device status locked so im all set.(nice to know that I also have global as an option among others) Thanks again!

Glad to hear it went well. Aside from a more recent security update, I don't know if you'll see any difference between the T-Mobile ROM and the International (global) ROM so enjoy it.
I know some folks wish there was more development for the OP7T but it's really pretty solid. Oxygen OS is smooth and Android 11 should be available for it by the end of the year. That being said, I'd love to see how the Paranoid Android ROM runs on this device! Hopefully that'll come soon.

Hello flashers.
Question here.
I have a US unlocked version G781U1/DS. Is it possible to convert to G781B/DS? The reason for this is European B version has dual sim support, whereas apparently it is disabled on US models. Otherwise why would Samsung put DS into model name for U1 and snap in a dual sim tray?
I think both devices have same hardware specs.
Will it work?
Thanks.
No, it will not.

Why would you want to do this? The U1 version is a multi-CSC firmware and should work as needed in any country. I have not been able to secure a FW set for the S20 FE5G as of yet, but if it was available, it could be confirmed or denied that the specific CSC you need is contained within. Again, I'm rather curious about the issue you're facing to lead you to want to do this. Technically, you should be able to flash any Snapdragon CSC that is built for the same device. That is speculative as ive not confirmed this, but that is how it has been historically from the S8 onward
I have tried all CSC versions available in CSC menu, none of them enables dual sim. Note CSC available are most for US carriers like TMB and ATT. There is XAA (international apparently) available as well but does not enable dual sim either.
I've read thread after thread and as best I can tell there is an EU version, a global version, an India version, and the T-Mobile version. The radios on the non-T-Mobile versions are different than the T-Mobile version (or so it seems).
What I have is a OnePlus Nine Pro from Amazon, fully unlocked, T-Mobile version. Works fine for me on T-Mobile. What I want is the unlocked firmware, as if I bought it in the US directly from OnePlus. Like the Nine that I got directly from OnePlus that I am returning because I want the telephoto lens and a couple other improvements the Pro has.
Since someone may ask, here is why:
Avoid bright magenta startup screen
Get patches more quickly
Get round icons
Debloated (esp. Qualcomm)
The feel of the phone, to me, is less than the Nine with stock unlocked firmware
The dialer is better on stock OOS 12
I don't want to lose the radio, I don't need an International version, I plan to stick with T-Mobile, so it seems like it should be easy, but I can't find the firmware. If the global version is the same as the unlocked, fine, but do I have to do weird things to keep the US compatible radio (like I read in various threads)?
Hardware version 22, software LE2127_11_C.19, if it matters.

Sorry, but if it is T-Mobile carrier, you have to unlock the bootloader with a token. There is a XDA thread on unlocking the T-Mobile bootloader if you are on a branded LE2127 model phone.

If you install any firmware such as the North American (Global) once the rom is installed you have to go into fastboot mode to unlock the bootloader. No rom comes unlocked....sorry!
This is what you want. Anything else and you risk breaking the radio.

I'm confused. Is the EU version the same as the unlocked version as sold in NA directly from OPO?
[edit], Yes I had read that and don't want to have to screw around with the modems; on the Nine I had several OTAs after unboxing it, the modem just kept working (on T-Mobile, who is my carrier). That page you reference says "You must flash the T-Mobile modem after every OTA" which is not interesting to me. And it talks about dual SIM, which I believe the NA unlocked version does not have (at least the 9 does not). So there is a firmware out there, presumably, that is different.
If I spent the extra money that I don't have on a new Nine Pro straight from OPO, I'd have the firmware I want. Instead I need to flash it, which is no big deal, but I can't find it. And I wouldn't have the pretty blue color : )
Of course I assume my experience with the Nine is the same as the Nine Pro, software-wise.

But you can't use the global firmware on the T-Mobile 9 Pro without losing the radio I thought? I figured that was the whole reason nobody has made an MSM Mod to flash the T-Mobile variant with global instead of EU software.

The T-Mobile 9 Pro has a unique situation where it only works right with the T-Mobile modem. The T-Mobile 9 doesn't suffer from this issue and can use any 9 modem. The process here has been proven to result in a usable modem once the conversion is done. I don't believe the same can be said of using the NA global firmware.
This is what you need to do for the Global Firmware.

The word that keeps throwing me is "global". So if I spent the extra $300 and got it directly from OnePlus in the United States, I'd have the global firmware?
The few threads with "North American" aren't explicit [enough for my tiny brain].
I've been testing the (pretty blue) one I got refurbed, and it seems fine, so I'm keen to fix the issues I've mentioned, and I don't mind the work.
FWIW, most of the time I see "global" on xda, it is different from "U.S.".

It's Global due to it not coming preloaded with T-Mobile firmware. I believe the 2127 you have came sim and bootloader unlocked. I bought my 2127 directly from T-Mobile and had to request T-Mobile to sim unlock it and request a token to unlock my bootloader from OnePlus site due to it being directly from T-Mobile. So, when you convert it to the Global version it will remove the T-Mobile bloat.
9Pro directly from OnePlus site for NA is 2125 and for EU is 2123.

OK, so that's a "no", it won't be the same as the 2125, software-wise. It won't have the very bright magenta startup screen, it won't have the T-Mobile software pre-installed, but there will be differences (what?) from the 2125 firmware.
Right?
Is it possible to get/load the 2125 firmware?

Your phone will pretty much run the 2125 software when you convert the 2127. Won't have anything T-Mobile at all unless you install T-Mobile applications. The main advantage of it all is faster software updates rather than sitting around waiting for T-Mobile to update their software for 2127 branded phones. That thread I posted will help you convert your 2127 to 2125 (Global) BUT! Keep in mind to make sure you retain your T-Mobile modem.

OK, so it is "yes", but with a caveat for the modem. Which is weird because, as I understand it, the modem from OnePlus direct purchases would be fine and fully support T-Mobile. No way to get whatever that modem is [and have it work perfectly]?
Thanks for your time going back and forth, by the way.

The 2127 has a modem specifically with T-Mobile bands as I like to say built for the T-Mobile network. The 2125 has a modem that still works with T-Mobile, but doesn't have the extra bands that come with the 2127 modem. That's why you should retain the T-Mobile modem before converting to 2125

This.
Out of curiosity, if you know, does this apply to the Nine (non-Pro)? I'm used to getting all the T-Mobile bands, until I hold on to my phone so long the network changes.

No, it doesn't apply to the regular 9, just the 9 Pro.
I bought the 2125 Pro for use on t-mobile USA and it has global firmware. I looked on the official OnePlus manufacturer tech specs and it has all the LTE and 5G bands that T-Mobile USA says they currently use in their support site. I don’t understand what this is about a special modem firmware for T-Mobile. Is there something I am missing here?
