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:
  1. 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)
  2. Is there a T-Mobile splash-screen
  3. 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
All of which are found here: https://forum.xda-developers.com/oneplus-7t/how-to/oneplus-7t-repo-oxygen-os-builds-t3997037

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?

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.
