Flashing 930U on my T-Mobile S7?

I just heard when the August security patch released on the 930U today two very interesting things. I wanted to see if they were true:
1. All Galaxy S7s released in North America are actually the exact same hardware model, but because of different firmwares not every LTE band or software feature is activated. For example, a Verizon S7 that is listed to supposedly only have CDMA and Bands 2, 3, 4, 5, 7, and 13 (which is pathetically lame by the way) can be flashed to the 930A software and work perfectly on AT&T.
2. I can flash the 930U software on to my 930T phone and turn my T-Mobile phone into a 930U. I'm still making payments on it and I'm not sure if this would unlock it or not, I don't care, I plan on paying it off and unlocking it through T-Mobile anyway. I'll get White Pages back which T-Mobile took away for their stupid paid service, and I can download the August security patch and from now on get my updates directly from Samsung.
So is this possible for me to do? I'm new at this whole thing. Also, if I did flash my phone into a 930U, will that affect me unlocking it through T-Mobile later on when it's paid off? Thanks for the help.

If the bootloader is higher than currently on the SM-G930T then it should allow to a flawless flash.

Yes, I just found out yesterday about how the T-Mobile S7 is currently the only version that has a different level bootloader than everyone else. The day had come when Verizon users can now do more with their phones than T-Mobile users, what a shame.
Could a pending upgrade be in store for the 930U firmware so it's possible to do again?

Probably maybe. I would say to hold on on updated the TMO S7 in hopes that the SM-G930U gets a bootloader higher that what currently TMO has and allow you to flash. Since it's unlocked then updates maybe 5% faster.

Thank you, I wish I hadn't found out that I could do this only yesterday. I'm still fairly new with the whole concept of flashing software, I know what it is but that's really about it. Hopefully I'll be able to flash the unlocked firmware on here and get those missing features back.

[Discussion] OTA updates for factory unlocked phones are dependent on carrier

I bought factory unlocked S9+ (SM-G965U1) phone a year ago. I always thought that software updates for unlocked phones are independent of carrier, and this was one of the advantages of owning one.
However, after Pie update I was stuck with January security update. I recently started to wonder why, and I stumbled across multiple threads on Samsung and T-Mobile support forums about this problem. BTW, I'm using T-Mobile.
Apparently, Samsung pushes updates to unlocked phones based on the carrier you're currently using! For some weird reason, they haven't pushed updates for those who use T-Mobile sim card:
https://doc.samsungmobile.com/SM-G965U1/TMB/doc.html
T-Mobile itself pushed updates for T-Mobile-branded S9+ phones: https://support.t-mobile.com/docs/DOC-37179
Here are Samsung updates for unlocked phones that use Sprint sim cards: https://doc.samsungmobile.com/SM-G965U1/SPR/doc.html
This is unbelievable. I don't understand, why in the first place Samsung differentiates unlocked phones by carrier sim cards. Software builds that are pushed are still the same in the end regardless of sim card, just check Samsung update webpage for different carriers (e.g. https://doc.samsungmobile.com/SM-G965U1/XAA/doc.html )
Anyway, I went to Bestbuy and bought a $1 sim card kit. I put ATT compatible sim card into my phone, and without any activation I got all of the security updates until September.
What the hell is going on? Are T-Mobile users stuck on putting different sim cards in their phones to get latest software updates?

Man, that must really suck.
This is the first time I'm reading that the updates depend on the SIM card. I have a T-Mobile phone variant using a Mexico SIM. So now my curious side has me if I should attempt to update using the T-Mobile software and seeing if I find an update with my Mexico SIM. Probably still won't update.
But, I have no way of TWRP backing up so, I won't even attempt.
I already changed firmware anyway, I have flashed stock carrier-free firmware on the phone and I'm on the latest security patch (September)

YES, this maddens me greatly! If I didn't know how to use Odin I would be stuck months and months back! All kinds of little carriers push the updates, but not T-Mobile! Thanks for the $1 SIM card idea, that sounds easier than downloading firmware and flashing with Odin.

I think that this is Samsung's fault. This is factory unlocked phone, so it receives updates directly from Samsung. For some reason, Samsung still differentiates between carriers by making CSC carrier-specific (even though pushed builds are the same for all carriers in the US!), instead of just being XAA, which it should be.

Actually, there is a post regarding this issue on XDA: https://www.xda-developers.com/samsung-treating-us-unlocked-device-owners-second-rate-citizens/
This is horrible on Samsung's end. It's sad, since this is the best phone I've owned so far in terms of hardware. But it'll definitely affect my decision, when it's time to upgrade.

Same issue I am currently facing. I flashed latest stock rom G965FXXUAETG3 and now my phone is on 'emergency calls only'. I am in Pakistan and I think carrier is locked now. However, in Service provider SW very PAK/ PAK,PAK, TEL is written.
Any resolution? Help needed.

I'm using my S9+ on Cricket Wireless here in the States. I had been receiving regular updates through the May 2020 update. It's now July 25, and I haven't received the June 2020 update. I check several times each day, but I keep being told that my "software is up-to-date." Will I ever receive the June 2020 update? Or will they jump me directly to the July 2020 update? If the latter, when might that happen? Or am I stuck at May 2020 with this former Flagship device? Thanks!!!

LIke myself and others. You will probably be stuck on the May 2020 update.

Factory unbranded phones should push updates ok OTA (without sim inserted and network settings reset before checking for updates over WiFi connection)- Is this not the case with your device?

Is there a download for the OneUI2.5/Android11 update available for the SM-G965U1? I have been checking Sammobile but it seems like the U1 is one of the last to still not have the update. I am on the T-Mobile network.

We are all waiting for this update because of wireless Dex

Seriously what is the advantage of T-mobile vs Unlocked?

I have an S20U now that is unlocked. What I love is that I get the updates faster it seems (although, the S20 has had way more updates than normal). I am thinking of getting the branded Tmobile one, I have never had any issues using their software and it seems to work better on the network. I do not honestly care about "bloatware" as I will at least be getting a 256GB model.
Anyone have any experiences either way?

I don't have any experience with TMO specifically, but what I do know is that typically the carrier branded devices get their updates WAY fast and more often than the Unlocked ones. I'm in the same boat, I don't really care much one way or another about the bloat. If I don't like it I uninstall it if I can or at the very least disable it

It is my understanding that the unlocked one can be used in any country and any network. Just switch sim card and you are done. The TMobile one, may be locked until you pay off the device. You also don't get the bloatware with unlocked (one less thing to Uninstall if you don't care for it).

There are 2 "Kinds" of Unlocked, you're referring to SIM unlocked, the other is the U1 devices sold by Samsung. Which I suspect what the OP is referring to

That used to be true, but not for the last couple of years. The unlocked US Note10+ (N975U1), for example, has gone through 18 software releases in the 12 months it's been out. Many of its updates came out within the first few days of the month, and included that month's Android security patch.
T-Mobile has been lagging for the past few months in its updates for both the N975U and the N975U1, but you can manually download and flash the latest unlocked software immediately.

Also, it is my understanding that Tmobile tweaks it's cellular radio's to perform slightly better than the unlocked version of any phone used on it's network.

From my experience, AT&T, the branded phones have the extras like wifi calling and VoLTE enabled and the unlocked ones don't. Some of the video call features are missing. I wouldn't have a problem with the bloatware but AT&T seems to force it back on and there is no way to remove it without root (which i don't do anymore). This has been my experience from Note 5 , 2 of the 7's ,note 8 and the note 9 I currently use, all have been unlocked.

Unlock has free caller ID builtin, Tmobile you have to pay for it. Unlock has no Tmobile branding or bloatware. Unlock version is easier to bypass tmobile hotspot apn, and usage limits
T-Mobile version has video calling on the phone app, unlock use to, but not anymore. There might be a few more things but I can't remember right now.

This simply isn't true with the Samsung phones. I have had both and there definitely is no difference in connectivity in either data or calls between unlocked and carrier version.

agree - that was a bunch of talk on this forum last year when the note 10+ was shipping . lots of cats on here were trying to say this and it was just not true. i had 3 unlocked phones on tmo and service was consistent.

I think he's referring to carrier aggregation. I don't know if it's a thing licked phones have that unlocked don't. I always go unlocked (so the phone feels like it's mine, lol) and can't say I've noticed a difference.

Thank you for your post. Does the Wifi Calling on Tmobile work on the Unlocked phone? I am looking at buying the unlocked 512gb model but have to have wifi calling when I am traveling internationally.

Does anyone know if the stock firmware can be flashed on any device if it's factory unlocked? I think the answer is yes, but just want to make sure before I purchase one used. I know your can flash the carrier firmware so I assume you can do the reverse.

Yes. and if you follow a few of the guides here you can "unlock" video calling and RCS in Samsung messages as well. And if you are really creative, there is another guide to expanding bands and tweaking receiving antennas
And the last question, if you buy the U1 unlocked, you can flash carrier firmware or unlocked firmware either way all you want, but keep in mind going from u to u1 firmware requires a wipe.
The old "unlocked" was slower to get updates is only true if you wait for Tmobile to release it. If you use Frija and Odin, you can pretty much get it the same day Samsung releases it. I'm too impatient to wait for Tmobile to "get around to" reviewing it and re-releasing what Samsung released weeks before.
Most of the "negatives" of having unlocked are long gone at this point and it tilts more into the positives.

U and U1 have the same radios in them, they are made specifically for the USA market. Depending on what carrier sim card you insert those bands for said USA carrier will be made available for the user. No need to expand bands. The technical specifications of the U1 and U models are listed on samsung USA website for cross referencing.

Anyone successfully using call recording feature on either version? Still looking for my U.S t-mobile variant..

T-Mo non-unlocked Samsung phones (maybe just the Note 20 Ultra though since I haven't been with Samsung since the Note 3 lol) have a bunch of issues. They're about one month behind on updates when compared to all of the other companies. Additionally, I saw someone mention that they have better mobile data quality. That is also true... I found that out once I manually switched to the Android 11 beta as my 5G speeds went from a constant 130mb/s down to 0.5 - 2mb/s without the firmware being specifically from T-Mo. In my settings, all of the mobile connection stuff is exactly the same as it was before...
Also, I don't have voicemail support. Yet another T-Mo problem (but you can easily add Samsung as a possible cause of that problem too)... Had to switch back to the Google Phone app just so that I could get old-school style voicemail (where you have to call your own phone number to get in).

This hasn't worked for me either. It's starting to seem like Samsung pushed some of their development onto the phone carriers now lol.
Hey Samsung, why not just leave Android alone when you get it from Google so you don't have to cause so many problems with your own, customized (ad filled, feature removing) version moving forward? Heck, I've already had some problems with a bunch of your apps and have gotten zero help or answers from you guys. That's the reason I've switched back to a bunch of Google apps, however, half of those didn't even work on this phone!!! But I messaged Google about these problems as well, and you know what? They fixed ALL OF THEM within two weeks.
I'll definitely be buying from a different manufacturer moving forward. Even more so since there's rumours spreading around online right now that the Note 20 was the last Note phone to be released since the upcoming S21 is going to have stylus support...

The difference between unlocked and t-mobile is that unlocked gets its updates directly from Samsung and is not branded.
While t-mobile version is branded and you receive the updates from t-mobile and not from Samsung. So delay or longer waiting time on updates would happen and maybe even won't get few of the updates.
Since t-mobile has to release them, which take longer time.

looking for "before-i-buy" details on the different versions, for using on T-mobile

looking for "before-i-buy" details on the different versions, for using on T-mobile
cant seem to find exact details on in2013 / in2017 / in2020 / in2025 but i have (obviously) seen those references around while trying to research the different versions
i presume 2 of those 4 versions are international and the others USA, please do correct me if i'm wrong.... and based on the descriptions from people who are "selling" the Oneplus 8 phone(s) all of these appear to be T-mobile compatible
i've seen that there are both locked and unlocked versions of the USA models.... and i also have easy access to some unlocked international models locally from 3rd parties.... which leads me to some questions:
Question #1
is the T-mobile OTA blacklisting for bootloader unlocking limited to sprint/t-mobile models, or would an SIM-Unlocked USA model also end up blacklisted for bootloader unlocking?
Question #2
is unlocked International a bad idea for usage on USA T-mobile due to availability of bands?
appears 4g and 5g would be accessible, but i don't know to what extent the coverage would be hindered (which i've noticed can be anywhere from non existent to severe cell frequency mismatch between brands / regions / models)
Question #3
am i looking at any kind of "technical difficulties" outside of OTA block, by bootloader unlocking on OnePlus? i am very new to the brand, coming from Samsung in the era before they were locked by default :silly:

Hi,
First of all, there are 4 versions of the OP8 :
IN2010 (China) IN2013 (EU) IN2015 (US) IN2011 (India)
The OP8 Prois the same, but with IN202_ instead of IN201_
There are also brand specific version: Verizon and T-Mobile. Those version are a pain (as I heard) to update even by the official version. There are some workaround to SIM unlock those, but they'll still be a pain to update and root. If you succeed in rooting that you'll be blacklisted for OTAs on those versions.
The USA version is different, not a pain to root or to OTA update, you keep OTA when rooting. In short that's the phone OP intended you to use. It's 5G, but not millimeter waves or things like that. I couldn't test 5G yet since I don't live in America, you have to scroll through the OP8 forums to find your answer.
And there is no "international version". Don't be fooled, International version is a way to lure buyers in buying chinese version but flashed with OxygenOS global. You'll buy the chinese version (with potential band mismatch), it's cheaper but you'll have issues with G-Pay and 5G (even 4G in some countries).
So #1: Carriers phone not only blacklist you when unlocking bootloader, they try to make it impossible for you to unlock it. Idk if it's the same with unlocked SIM (but I don't think so)
#2: Since international is in fact chinese with global software (and not chinese specific) I highly recommend you not to buy it (even though the price looks sexy)
#3: Unlocking bootloader requires you to wipe your phone, otherwise no issues if you follow the instructions. If you flash a ROM or install magisk modules then the stability of your phone depends on the dev's work and not the OEM anymore.
I might be wrong with the Carrier Devices banning unlocking bootloader since I'm not from America so search more on the internet.
Hope this helped, have a good day :good:

there is definitely an IN2017, it shows on phonearena and gsmarena spec pages, but in the USA each carrier has a designated model number within a same phone model (like 900P 900T 900V) so that might be what's going on with IN2015 versus IN2017 (i'm guessing GSM model versus CDMA model)

You're right, I forgot to put it, IN2017 is the CDMA.
And CDMA are modified versions of the IN2015. That's why you can't use the same cases for CDMA and GSM versions. They added in the phone, the hardware to make their 5G technology work. So CDMA and GSM technically are all American (since they're located there), but they're different, especially for OTA. It's not OP that provides updates for CDMA phones, that's T-Mobile or other carriers, and I heard people here complaining the updates are slow to be available. I don't even know if Android 11 is available for them yet.
That's why I advices you to buy the IN2015

There is a MSM tool for t-mobile that is up to date with the latest firmware, 10.5.20.

sounds wonderful to me i'm honing in on the decision to buy, just having a hard time finding non-retail prices, other than Swappa
would you recommend getting the T-mobile and converting (which effectively means unlocking? lol) or does that come with caveats avoidable by just buying one already unlocked?
it sounds like there's no difference but ughh... idk i'm in information overload mode trying to hit the ground running lol

If it was up to me, I would just buy the pro model if you can afford that. I ended up buying through tmobile to finance mine and had my device sim unlocked so I can unlock the bootloader.

I have IN2017 on Tmobile and would recommend it. The Tmobile vendor rom works better on their network for obvious reasons, for example 5G standalone doesn't currently work on the Global OOS (oxygen OS) roms.
To answer your specific concerns:
#1 I've never heard of Tmobile blacklisting anyone for unlocking or rooting. Just make sure the imei is good if you buy used. Use a legit site like Swappa.
#2 Yes avoid the "international". Stick to IN2015 (Global) or IN2017 for use in the USA.
#3 Bootloader unlock on the IN2017 requires a clean esn/imei. You fill out a form and Tmobile gives you the unlock code a week later.
After bootloader unlock you can easily root with Magisk or flash pretty much anything. On my 2017 I've ran the tmobile rom, OOS10, OOS11, and gone back and forth.

i have a feeling if i walk into a T mobile store and ask them for a bootloader unlock code form, they're going to look at me like i have an alien doing a handstand on my shoulders...
havent met a single employee yet who could figure out why putting a T mobile sim in my old Sprint phone is a bad proposal for coverage lol my hopes are pretty low with them.
could you tell me a little more about who / where / how to acquire the form from?

Hi,
First of all, there are 4 versions of the OP8 :
IN2010 (China) IN2013 (EU) IN2015 (US) IN2011 (India)
The OP8 Prois the same, but with IN202_ instead of IN201_
There are also brand specific version: Verizon and T-Mobile. Those version are a pain (as I heard) to update even by the official version. There are some workaround to SIM unlock those, but they'll still be a pain to update and root. If you succeed in rooting that you'll be blacklisted for OTAs on those versions.

They say you won't get updates, but my phone has wanted to update for over a week now. Maybe security updates aren't affected? I have IN2017, unlocked bootloader and rooted.

I have IN2017 on Tmobile and would recommend it. The Tmobile vendor rom works better on their network for obvious reasons, for example 5G standalone doesn't currently work on the Global OOS (oxygen OS) roms.

yes yes i'm re-quoting the post lol
are you saying that OxygenOS is the global rom? also, can you clarify what is being described by 5G "standalone" ?
just got my IN2017 and it's on oxygenOS 10
it is unlocked and my account is Sprint (and will remain that way) but sprint's system was too slow to reflect that this phone was activated on the account, so the T-mobile store wasn't able to put a T-mobile SIM in it (yet)
...with that said, the phone says 5G is connected and speed tests are.... pretty bad... barely meeting mid tier 4G standards... how can i definitively confirm or deny if i'm on the global rom

Bro....
You will need to flash it. It doesn't come preinstalled on Sprint\tmo.
I'm using your exact setup. I too have the Sprint sim in my Tmo OP8
If you are on 10nand want to go to global, there is a thread on here that will take you through the process.
Follow the guide carefully but confidently. It does work and will not brick your phone.
You will convert to global a10... I had issues with cellular signal after converting.
HOWEVER, after upgrading to A11 global rom (local upgrade) everything works perfectly.
I'm on OOS11 Open Beta 3 with sprint sim on the IN2017.

based on what everyone's said so far about the global rom, i have zero interest in it.... i am merely trying to understand if i am on that rom now as a result of possible shady dealings from the seller on Swappa, based on how the post i re-quoted was worded. it threw me off.
but from the sound of it, i get the feeling OOS is not the global (or at least the version i have installed is as it should be -- stock TMO)
and i'm rapidly falling in love with this thing... it's so &@#%*$^ fast

Don't know what you've heard about global but it puts Tmo stock to shame

Simple answer. Buy the phone from oneplus.com. I did and have had no issues at all on T-Mobile. Trust me, with any OnePlus devices, you absolutely want to be able to root right off the bat and install viper. Audio tends to be a big problem with oneplus phones, and only viper seems to solve the issue.
The phone is $600, and a bargain at that price.

Just look at the version on the about phone screen. The TMobile software builds end in IN55CB (latest is 10.5.22.IN55CB), and the global roms end in IN21AA.
About the 5g standalone, that means you can connect to the 5g signals alone. This only works on the Tmobile rom right now. You'll see NR-SA in apps like signalcheck or network signal guru. The alternative is NSA (non-standalone) 5g where the phone has to be connected to a 4g signal at the same time for 5g to work. This gives you 5g speed but with higher latency and it uses more battery. It's just like when Sprint 4g came out but early phones needed to stay connected to the 1x signal as well.

Question Flashing unlocked firmware over carrier firmware?

Like the title says, is this possible and can it be done without wiping user data? Thanks.

Probably not worth the trouble. Always assume you will lose the data and back it up redundantly.
I thought there be a night and day difference when I got the unlocked N10+ N975U1 vs the AT&T variant N975U. There wasn't. The unlocked version actually had some bloatware not on the AT&T variant
Easiest and safest thing to do is package blocked the carrier bloatware. Verizon does some screwy modes to their devices so getting rid of that be nice. AT&T does not, that surprised me. Some users might like some of the AT&T apps.

It was successful, thank goodness. See my follow up here https://forum.xda-developers.com/t/f721u1-firmware-now-available.4484639/

Notice much difference?

Yeah the main stuff are:
1. Rcs with jibe server works now. Before it used att server so it wouldn't connect properly with other users
2. System updates come directly from Samsung instead of att

Don't use either.
Updates is one of the first things I disabled on my N10+'s. One's on Pie, the other 10, I prefer Pie though. Once Google started rolling out scoped storage I bailed.

AT&T/Samsung have a nasty habit of screwing up older devices with firmware upgrades. Just had a pair of Buds+ screwed up like that a few months back, now they need the firmware rolled back*. S4+, same deal a few years back, but bootloader was updated too, no rollback.
If an OS is running fast, stable and fulfilling its mission... I let it be.
*I have 2 new pairs of Buds+, they sound identical and like my original pair use to, grrrrr.
Went with them because Samsung's newest release lack the features I want. Rather annoying.
The Buds+ have a 11 hr run time, light, don't fall out and sound good.

Sorry I should've posted my question here, instead of creating a new thread.
I recently purchased a flip 3 and am on a payment plan, tmobile won't unlock my phone unless I pay it off in full. Is it possible to flash the default software of the unlocked model so I can get updates from Samsung and still have my sim work? I'm not switching carriers, do I need the tmobile version of firmware for data/phone to work if the phone isn't unlocked?

Phone service will still work perfectly fine on U1 firmware, but you may lose lose some carrier-specific features like wifi calling etc. But.... the U1 models don't always necessarily get faster updates than the carrier models. For example, with the most recent update, the carrier model got it 2 weeks before the unlocked model. So if that's your only reason for wanting to change firmware, I'd advise against it.

What I'm concerned about is tmobile eventually stopping the updates way sooner than Samsung. The carriers don't usually update a phone as long as the vendor so to avoid that I would rather not use T-Mobiles version. Thanks for the reply, it was very helpful.

Incorrect. Every single model's lifespan for updates has always been the exact same, whether U or U1

I downloaded the unlocked firmware via Frija for SM-F711U1 / XAA and flashed it onto my At&t unit using patched Odin. Lost my data since the install didn't work without flashing CSC but booted up and working just fine now. No At&t bootscreen or bloat
