So I just got my 7 Pro a few days ago from Tmobile and so far its working great! I saw the guys over at XDA were able to get the software so I can flash the international firmware on my phone so I can start getting updates when One plus drops them instead of waiting for tmobile. Is there any downfall to this? Will I loose out on any features from Tmobile? I am currently using a cell spot, would that still work? And for the last question will I be able to revert back to the tmobile firmware if I decide to trade in my phone? Thanks for the insight!

From what I understand, Wi-Fi calling won't be as quick switching back and forth, you will absolutely lose RCS UP and the video dialer. I'm assuming you have the 4G LTE CellSpot V2, that will still work just fine. And the dev that posted the MSM to switch back and forth has demonstrated that there is a path back to the T-Mobile firmware. AFAIK, as long as you don't root the phone you should be good to go with a JUMP or JOD trade in in the future on the international firmware, but it's always best to have the path backwards just in case.
Generally the downsides are not very noticeable. "losing" RCS isn't bad considering no one really uses it still. Also even if you root your phone, it's not a problem with JOD or JUMP. But really, if you don't plan to root and take advantage of those perks, and you're satisfied with your current vanilla tmobile experience, it wouldn't really be worth your time. You're free to do what you want without any permanent damage probably.
RCS is actually the deal breaker for me lol. This is my first TMobile phone and being able to use RCS with my buddy i actually get to share videos with is great. The only reason I wanted to flash is to get the updates faster.
I recently purchased an S8+ on ebay. It was listed as a G955U. I waited till my current billing cycle on my other phone was up to port my number over to the new phone on a new carrier. The 1st day or two, I had very spotty LTE coverage. It would constantly stop working, and now will not work at all. It'll say I have LTE, but it won't work. I've been trying to sort it out, and found that the phone is actually a G955W, converted to a G955U. Is there any firmware I can flash, or anything I can do to be able to use LTE, or am I stuck with a phone that has no data? I'm using a T-Mobile MVNO at the moment, but could easily change to an ATT MVNO as well.

You should be able to just pop a new sim in and it personalize but to start you off if it don't. You'll need to flash the current level of bootloader revision combo file then flash a current w firmware. The u u1 and w are all the same device essentially a u1 at heart with personalized software. But that should get you started
Thanks. Unfortunately I was going back and forth between different firmwares, and accidentally flashed U combo file to a W firmware. Phone no longer turns on.
Hi
Have Samsung galaxy 2 fold at&t unlock
Can I change Carrier from att to t-mobile I flashing T-Mobile firmware or can I just Flash csc??
if your phone is sim-unlocked, once you insert a t-mobile simcard it will change the phone to t-mobile. no need to flash anything.

Yes, it works for making phone calls, texts, even 5g. But you won't get OTA updates. At least that's what I was told. I'm typing from a purchased AT&T unlocked Fold 2, with a TMobile sim inside. It works fine, just no updates. Still on One UI 2.5, and android 10. I'm actually here hoping to change this by flashing a TMobile rom. I did a little research last night, and it seems a little scary with the danger of bricking the phone. Back in the PPC hayday of flashing roms, I was all over it. I even flashed a few roms on my s6 years ago, so I have some experience with Odin, but it still seems nerve wracking because I can't return this phone if I brick it. Bought it used.

@vinscuzzy I feel you because I understand what you're going through. I used to flash my devices back in the day. I haven't flashed or rooted in a long time but like you, I also have an unlocked AT&T branded Z Fold2. It seems easy enough. Any reason why you would install the T-Mobile firmware rather than the U1 Unlocked version?

Theoretically I would think the unlocked version would be better because when theres an update, I'm guessing, we wouldn't have to wait for the carriers to do their stuff to it. But I'm not 100% sure if that's how it works anymore. The last truly unlocked phone I had was a Nokia 1520.3, with windows mobile, and it was great, BUT if I remember correctly I had trouble with wifi calling, visual voicemail, and tethering. I actually asked @zimgir124 the same thing in the other thread about which one is more beneficial, but haven't heard back yet.
Well, I just found another thread on how we can go back to AT&T in case we need to.
If it's running well now I would not be concerned with updates. You could well end up with a less functional device by updating.
I unlocked my note 10+ 5g from t-mobile, but it won't get service with verizon.
When I install a non-tmobile sim, the software does not switch from tmobile for some reason.
Also Sam Mobile only has t-mobile and metro pcs firmware availible for the sm-n976u
Does anyone know if there is a way to get the phone working with verizon? Thanks.
-God Bless
Try clearing Sim card tool kit data.
Network reset.
Clear system cache.
Edit Access point names to correct values.
That's all I got but sure there's more. Never had use more than the above but never changed carriers. Verizon advanced tech support should be able to help... AT&T would.
The Verizon Note 10+ 5G has a different model number. So they probably won't allow the T-Mobile/Metro/AT&T version on their network

I think you're correct. AT&T is compatible with Tmobile but not Verizon according to B&H Photo compatibility charts.
So it look like AT&T is in your future. AT&T is easier to deal with anyway. Do not use a corporate store though, use over the phone or online AT&T.
It may be possible to change out the C port PCB for the Verizon variant. Yes that PCB controls internet access. I can't confirm this is the only difference though! That PCB is only $20 and relatively easy to change out.

It's gets service with att, but it still has the tmobile boot logo. I flashed the att rom, but it didn't help. The carrier is supposed to automatically switch when you insert a different sim card right?
I also tried *#272*imei# but it says "unable to process the request"

Is it on Verizon or AT&T???
My 60 second attention span is kicking in... now.
As for switching sims I never had to.
The boot logo is the least of worries.
Be glad you didn't brick it.

It's actually super difficult to hard brick a Qualcomm device, and even if it is hard bricked and only enters EDL mode, it can be fixed as long as you have the correct files.
There are too many safeguards in place between Qualcomm and Samsung - the average user will always be blocked from doing anything that would brick a device. There's really no danger in flashing firmware whatsoever

I'm trying to use it with att because it won't get service with verizon at all.
It's very annoying having the tmobile bloatware. Also it should be compatible with att's 5g, but it only gets lte.

So then I'm assuming that it did not automatically change over to the AT&T splash screen and bloatware when you inserted an AT&T SIM?

Right. It does not have a multi-csc mode for some reason. I thought all samsung phones had that by default.

I'm guessing the only option left is to root the phone, and then start manually removing things.

My method doesn't involve root, no. You can't root if you've taken an OTA update in March of this year or later
I hope I can be of some help.
I recently ordered a Note 10+ 5G - Locked Verizon from a popular online re-seller. When I turned it on, I was greeted with an AT&T boot logo. I was pretty upset, but I though I'd try to get it up and running on Verizon before spending a couple weeks sending it back and getting a replacement. I tried Verizon's online software and I couldn't get beyond the IMEI change. It kept telling me that the Note's IMEI was what I was already using with my Droid, which was obviously not the case. So, I headed into my local Verizon store.
Nothing they did would get my 4G SIM to work, so they swapped out for a 5G SIM for free, then switched my hardware IMEI numbers and proceeded to have a some difficulty getting on the network. After doing a network reset, it seemingly worked. More on that below. I was getting both data and voice over network. I was able to transfer my setting, apps, etc from my Motorola Droid with Samsung Switch. The phone indicates both 3G and 4G signals as I travel around town. 5G is not available in my immediate area, though it is in some cities I occasionally travel to, but I'm unable to test that just yet. I become aware that there are differences between Verizon's 5G and other networks and it seems the non-Verizon phone I have is probably for the best in terms of compatibility.
Unfortunately, texts frequently take 10-30 seconds to send. Images, gifs and other non-text MMS can take multiple minutes to send and sometimes just fail. Other times the recipient will receive them twice. I feel like this may be due to the poor coverage at my residence. Further testing in areas of good to excellent coverage are necessary. I tried changing the network settings from Settings > Connections > Mobile Networks > Network Mode, but anything other than the default "GLOBAL" would result in a disconnect of data and voice services. The only way to fix it was Settings > General Management > Reset > Reset Network Settings. This would restore the Mode to GLOBAL and bring back data and voice services.
In an effort to remove the AT&T branding, I learned how to trigger a carrier switch, dialed the code and changed it from AT&T to XAA. That got rid of the AT&T boot animation and I was able to remove all but 2 stubborn AT&T apps. I noticed that my android version was 10 and UI was 2.5, so I set out to update.
This is where things got frustrating. Every attempt to update through the settings > software update was met with failure. Try again in 24 hours, it would say. I assumed this was because I was now using a Verizon sim on an AT&T firmware, but I wasn't sure. I thought I might be able to flash to a Verizon firmware, but after several versions and some more research, I learned that going from 976U to 976V was not possible.
So, over the course of several days, I learned a lot. I looked up the firmware releases on AT&T's website for the 976U and saw that they matched the T-Mobile and MetroPCS versions. So, I settled on a T-Mobile version of Android 11 / UI 3.1. It updated without any issues and even remained in XAA mode. No bloatware, no loading images, all settings and apps the same.
So, even though I have an unlocked AT&T Note 10+ 5G 256GB and you have a T-Mobile, the fact that we both have a 976U model, I think there is hope for you to get up and running on Verizon.
Hope this has helped.
I have a TMO S22U and basically I immediately flashed to U1. I'm just curious are there any advantages I'm missing out on being on U1 opposed to T-Mobile U? I know there probably aren't many but I'm just curious.
Some say U1 us better. I'm At&t so probably someone on Tmo will chime in. But for me, U1 offered nothing over U. I mean yes no At&t bloat but I can disable what I don't want on U to get the desired affect.
My biggest thing was the T-Mobile splash screen, it sounds SO DUMB but flashing to U1 made it literally 100% Samsung for me I'm just wondering what could have been lol
The only thing I heard, but I am not certain about is that you lose the TMO visual email capability. Otherwise I have not heard anything else. I am on TMO and I kept mine on U. As butchieboy said, I just disable what I do not want. In all reality, there is not much from TMO that is loaded on the system side. More of the bloat is from Samsung and Google.
Thanks for the speedy replies guys much appreciated
One thing I noticed when I did the same thing, was I could not get 5G Ultra Capacity to work. Not certain I was doing anything wrong, just wouldn't work for me.
I think I read somewhere that you do get it, but there is no icon for it in the U1 image. It will show 4G LTE. Check your download speeds.

I did, 2 days apart in the same spot, the icon showed 5G as did the speed test connection type, but the speeds were much slower than 5G UC, almost 400 Mbps difference. Switched the firmware, back to the insane, almost WiFi type speeds.
Did you check the mobile networks setting to make sure 5G is available and selected?

Yes, that was my first thought. It never quite worked the way I should have.
preinstalled crap apps on tmo firmware
The main benefit for me on the unlocked firmware is the built in called id and spam blocking. For att you have to pay extra and tmobile has it on its best plan. But still think it works better than tmobiles implementation. And since i change carriers often i like to always have caller id and spam blocking no matter which one i use.

I downloaded the S980U1UEU1 firmware which on the latest update ends with AVCK. Used Frija to download it
Carrier firmwares usually get updated a week before the u1 series does.

Would've just been a considence. U1 firmware does connect to 5G UC just look at the service menu and it'll confirm if your connected to N41 or not.
But I moved back from u1 to tmv U firmware due to having weird call /sms issues where it would just stop working and only fix was a reboot. Hasn't happened since switching back to U firmware.
Here's an interesting question..
I was on TMO and I bought a S22U from TMO (unlocked it with them afterwards) and of course it was on 5GUC and everything (I used ESIM). I got another sim (Mint Mobile) and when used as primary it would show 5G+
After a while, and just out of spite of the hideous 4G LTE TMO icon I Flashed the U1 firmware.. I'm no longer using TMO as I ported my number to Mint and it has been good.. Would it make sense to return to TMO U firmware or should I stay in U1 as Im no longer using the TMO sim?

Probably fine on U1. You're no longer connecting to anything advantageous besides updates being slightly faster with U.
I'm with T-Mobile, but purchased mine directly from Samsung.. I have the S22 Ultra U1. Since my last phone purchased from T-Mobile A52 5G. biggest change, No daily spam calls or text.. What a difference that makes.. With T-Mobile, their so called Spam blocker was notihng more than a spam attractor. Plus no more of the hidious bloat and splash screen..
I have the unlocked and I dirty flash switch between U and U1 depending on which newest ROM is out. There's absolutely no difference save for the annoying TMOB splash screen and that it says UC ... But from my extensive testing the speeds are the same whether it says 5G on the U1 or 5GUC on the U.
