955U at Tmobile store.

So I went to a Tmobile store and looked at the Galaxy s8+ and noticed the model was 955U not 955T
It was of course their demo unit which was strapped (tethered) to the desk which makes it impossible to feel properly in the hand... But whatever.
Curious if only the demo model was a U variant or what? I never payed attention to other models before now?
The U variant of other Samsung models, do they have Locked bootloaders? Is it only the F variant that is unlocked (bootloader)
Sent from my Rooted Galaxy S7 EDGE on Android 7.0 Nougat, here's the instructions how to do it!

The SM-G955U is suppose to be the Unlock variant of the S8+, which make it super interesting, Hope this comes with unlock bootloader

All snapdragon s7 edge have locked bootloader including the g935u so I'm assuming the same thing with the s8 hope this helps (unless someone finds a way to root s8)

With the S8 and S8+ they are using single SKU..Verizon, At&t and T-Mobile will be the same model number. Screenshot of my S8 recovery screen.

According to Samsung.com and the phones full specs they are each different

You guys think flashing another carriers firmware unlocks the missing bands?

None of the U's are bootloader unlocked. They are just network unlocked. At least starting with the S7 in my experience. Its a hopeful thought though. I hope I am wrong

That is absolutely right. Only exception being TMO will work with a prepaid MetroPCS sim and ATT with work with a Cricket sim.

That's really interesting. So I purchased a T-mobile model directly from Samsung.com (paid in full), will I possibly be able to use it on At&t?

From what I read I'm not sure how long it will take to have T-Mobile officially unlock it. They have an app for that but they have several different criteria as far as being a current customer or a prepaid versus postpaid customer. Ive never unlocked a T-mobile phone with the app or a third party unlocking service so maybe someone with examples could chime in. It does seem AT&T has an easier online unlocking method for current and non customers to simply fill out a form.

And the U models are slow with updates

Samsung doesnt care if it is unlockable or not, see, the exynos variant can be freely unlocked.
It's the us carriers that ***** about unlocked bootloaders nothing more.
And you paid for a piece of hardware that is known for being locked down, nothing hidden.

What is your point? It's not like they sell equivalent locked and unlocked versions in the us (no, the 950f is not equivalent as it does not work on ~half the us carriers).

First of all, it's not my petition I didn't make it or sign it lol. Exynos and snapdragon do not have equivalent radios the need for CDMA in the us is the whole reason the soc is different.
My comment was in response to your "you knowingly blah blah blah" comment, as it's irrelevant given there isn't an equivalent unlocked alternative.

Okay everyone. I purchased the UNLOCKED variant. So what carrier is keeping my boot-loader locked?
Spoiler; no-carrier. Samsung is keeping it locked.

If samsung made an unlockable bootloader for the non carrier version of the snapdragon s8 then you could just flash that unlockable bootloader to an lets say verizon s8 and defeat the whole bootloader locking story., that's why every SD835 s8 is locked.
And you said you didn't create the petition but Lol you used the same nick from xda to create the petition, just stop being pathetic, i'm out

Sure, but when did OP claim they didn't make the petition, and who DID claim they didn't make the petition? I think the guy is all confused haha

This is not the way people should ask manufacturer for things like this.
Only way to get anything done is to find connection in big Android news web sites, tell them to publish poll 'Would you buy next Samsung flagship if it will have locked bootloader?' and then put all this people on FIRE there!
And of course, if they persist, people should persist too.
Simple as that.

I too, will vote with my wallet when choosing my next phone and tablet. If Samsung doesn't leave me a real option for unlocked bootloader, I will spend my money elsewhere.

Just to mention here the Chinese version which is a snapdragon variant has a unlockable boot loader. The US variants don't, the question is why would Samsung do this, if not requested by a carrier otherwise every single snapdragon variant would be locked but they're not.

What about 950/955W? All Canadian phones are carries-unlocked and yet Samsung keeps the BL locked. No reason whatsoever. Definitely will go with a different brand once my S8+ gets old.

Dam my samsung order is on its way, and just found out about this... Someone is canceling the order now.

Carriers can opt-in or out, that's the smart way to do it for Samsung
Please add Snapdragon Note 8 to the petition title, and you will get more signatures; also, please share this on the S8+, and Note 8 XDA pages too--if you add the Snapdragon Note 8, of course. Carriers can opt-in or out, that's the smart way to do it for Samsung. For example, besides the US Snapdragon S8+, my other phone is a T-Mobile OEM unlocked Motorola Moto Z2 Force. T-Mobile and Sprint allow Lenovo to OEM unlock the Moto Z2 Force, while Verizon and AT&T do not allow it. Samsung cannot blame carriers, because some carriers obviously allow OEM unlock for a different phone that has the exact same CPU/chipset as the aforementioned Samsung (i.e., Qualcomm Snapdragon 835 mobile platform). Samsung has no valid excuse and cannot shift blame to carriers, but why should they? They can save money off of voided warranties via allowing OEM unlock, and give owners what they want at the same 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

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.

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)

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.

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

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.

Flash Canada firmware on US unlocked

So someone is the Fold subreddit said that he was able to flash the Canada firmware on his US unlocked fold and everything works including 5G. Is this true? Are there any downside from doing this? Thanks for any imput.

My understanding is that you need a device that supports the bands your carrier uses, that's all. The U1 has the widest carrier coverage. I have tried to find info on whether you can flash a firmware to get other bands, and perhaps that's what you are asking, but I doubt this.
Which carrier are you on?

Yes it is possible. They are the same device and you can cross flash. But why do you want to?

Not so much wanting to but was just trying to educate myself if it was possible. The whole discussion was to get the new Android 11 update sooner since unlocked models are the last to get it.

I am on tmobile. It was a discussion to get android 11 sooner instead of waiting.

I went ahead and did it ...I'm actually loving it! I'm just going to keep the sm-f916w version since it seems to get the faster updates and also as a plus I can see less samsung spam ads for some reason. I could be wrong but my samsung pay no longer displays ads all over the place as it has a more clean look. I dont get multiple notifications about turning on my phone finder offline or whatever as the US version did. That was driving me nuts!

I flashed it to my Tmobile U model yesterday which i had U1 on. Works fine.

Question Exynos/HK versions: AT&T LTE band question

Hey all,
I'm looking at getting an Exynos or an HK version of the S22 series. I saw none of the other versions besides the U supports bands 29 and 30 that AT&T uses. Since they seem to be the more minor bands, how much does it matter and how much does the lack of those bands impact service? And does AT&T ban those S22 versions from their 5G networks?
I'm starting to get tired of OP, but I want something I can tinker without having to deal with AT&T's Sammy versions.
Thanks!

AT&T won't support the international models on their network or so various users have said in other posts. You end up locked out. T-Mobile doesn't do this but the long range 5G and LTE band 71 is missing from the international versions which would mean no coverage in any areas using band 71. Either way you are screwed on AT&T and T-Mobile. Don't have any info on Verizon. Best suggestion is. (Don't Do It)

Crap. Guess my only option would be getting an AT&T version and using a paid service to unlock the BL and SIM.
We already tried T-Mobile last year and had a really bad experience with service and network quality, so they're out.
Thanks for the info!

You might want to rethink the Exynos version and look at one of the SD versions that can be rooted.

I am afraid you will not be able to get the bootloader unlocked (I may be wrong there). Rooting is not possible on the US or Canadian S22. I just switched to TMO this year and so far have had no issues. I use their 5G home internet too.

So is that the Hong Kong and Korea versions? Again brings up the question of if bands 29 and 30 missing impacts service and if so, how much.
If I get an AT&T BL unlocked with a paid service, can I root using the method listed in another thread?

I don't see the S22 series in the list yet. So might wanna further research that.
PSA: Unlock Bootloader on Snapdragon Galaxy Devices with SamPWND (Paid Service)
SamPWND is a paid remote service that allows you to unlock the bootloader on Snapdragon Samsung Galaxy devices sold in the USA and Canada.
www.thecustomdroid.com

There are many posts on here attesting to the fact that the US models of the S22 cannot be rooted. The BL cannot be unlocked, so no root.

May I ask what you are trying to achieve with root? Do you have something in mind or do you just want a custom ROM. There are other issues with rooting the phone. Main one is loss of Knox. This will stop the Samsung apps from working. So there is a trade-off no matter what.

There are magisk mods I run on my phone as well as some Xposed mods.
Not terribly concerned about Samsung apps. I haven't had a Samsung phone in years. Last one I had was an S8 and I only got that thru insurance when I lost my OP6.

Understand. Just wanted to let you know that things like Samsung Pay and Health Monitoring will no longer work and this can not be fixed if you change your mind. I did read that AT&T will ban any international phone from their network, so you do not want to go that way if you intend on staying with them. I think there was talk about the Korean model being SD and was missing band 71 (I think). There is no full solution out there unless a way comes along to unlock the BL.

AT&T doesn't use 71, so not a big deal. T-Mo did.
We tried T-Mo in the summer and had a horrible experience. We went running back to AT&T after 3 months.
When you say banned, are you talking about just the 5G or the entire network? I'm already blocked from 5G with my OP phones. I can't say I miss it as I wasn't impressed with it on T-Mo, and LTE does what I need it to do. Outright banning seems like a stupid thing to do, especially as a lot of foreign travelers could very well end up using AT&T while they're here. But then again, it IS AT&T ...

From what I read, AT&T will ban your IEMI if it is an international phone so it will not work on their network. They are the only ones that do this as far as I know.

Check this out. Long read through all the posts, but may be able to answer your questions. There are other discussions on the US models and international models, so just look around.

You ain't gonna win with the U.S. Carriers. They absolutely don't want you rooting your phone on their networks. Why do you think all U.S. models have unlockable bootloader's when shipped from Samsung? Because they demand it. They also know you will try to get around it and when you do they will screw you by banning your device. If you gotta have a rooted phone move to another country lol.
