Question Flash s908u1 on carrier based s908u - Samsung Galaxy S22 Ultra

I just read a how to on flashing firmware on s22u. I purchased it second hand and was told it was unlocked. Wasn't true but the seller basically said sucker bye bye. I paid to have it unlocked. Working on different carrier though I hate the att bought ware. It's still server locked by att because the seller owes money on the account. Att won't help because I don't have the account number and can't get it. Samsung can't help because it is a carrier version. Samsung offered to trade in for s23u +$700 more. I was hoping to flash Samsung's s908u1 firmware over the s908u and make this phone useable.

Canadian idol 3 sim locked

Hi just purchased my idol 3 from koodo in Canada it was locked and was wondering if anyone has a good place for unlocking? Thanks
If it's showing sim locked you should return it. Alcatel would have no reason to lock it since they are not selling the phone via a carrier....if you ended up getting one someone fiddled with previously it's possible they managed to lock it....you won't find any place setup to unlock the idol 3 since it's intended to be sold unlocked.
In Canada they only sell with carriers. Telus koodo and bell. I put my wife's rogers sim in my koodo phone and asked for a unlock code. Even when you go to purchase a phone on alcatel website you can only purchase from the cell companies in Canada that offer the phone. We cannot purchase from Alcatel.
There might be an unlocking company online that will charge to unlock it. Or a company that will ship a US version to CA.

Other canadians here have identified their phones as the 6045i (when everyone was uploading their stock firmware) so it's the same model as USA.
If the Canadian is locked, then it would still be beneficial to get a US version or paying for an unlock code or service.
Thanks for the help guys. Sucks that the Canadian model is locked. But not surprised. Lol
Def locked when bought from a Canadian carrier. They lock everything except the nexus phones...even when bought at full price.
I'd try cell unlocker or some other 3rd party unlock service. Telus/Koodo charges $50 for an unlock code.

For that much would be cheaper to purchase in usa...have shipped to friend in usa then reshipped to canada....can then flash the stock canadian firmware we have online.
Yeah, Canada's wireless is borked... The CRTC did change all the rules and did force the carriers to provide a way to unlock in a contract and immediately unlock when you purchase the device in full, the only problem is, the morons forgot to add the part where the carriers should have to do it for free, when you own the device. So, now they can still charge... looks a lot like it did before, with just more pointless words in the act.
The free part was unlikely to be an oversight. It was probably the most requested part of the code of conduct. They stopped short of free and price controls when it came to unlocks.
Bit of a shame, I think if a contract has been fulfilled, they should do it for free.
At least there's a trend lately of affordable high performance phones... Hopefully that leads to fewer phones bought on contract up here. Many normal customers just aren't aware if the "device balance" mark up, and plan mark ups. Better off paying outright.

How to outright purchase a TMOB S7 after launch for carrier unlock?

Assuming that TMOB does not lock the bootloader so that the S7 variants can be rooted and custom roms eventually installed, what is the best way for a non-TMOB customer to outright purchase a TMOB variant of the S7 so that it could be unlocked and used on another carrier, like T, that locks their bootloader?
I am going to assume here that TMOB will use the same TMOB Remote Device Unlock App that requires the IMEI to be in their DB and registered. Looking at the TMOB pre-paid site, the phones available seem not to be very modern so I would guess S7 will not appear there for many years.
Is it as simple as going to a TMOB store and doing an outright purchase without a plan?
Last time, I pre-ordered a Note 4 prior to release and had to setup service and cancel within 30 days which was a bit of pain.
I am looking for a simpler retail channel.
:fingers-crossed:
Right there with ya, would love to find out.
Carriers in the US are finding new ways to keep users from unlocking phones and moving to other carriers. These new monthly installments and required post paid plans are one of those ways. Best bet would be hoping for third-party unlocking services to work with t-mobile's version soon after launch.

I'm in the same boat, but I don't believe a simpler retail channel exists. Each release since the S6 has been locked down with the TMOB app and even direct customers have a hard time unlocking within the first 21 days. Threads on XDA discussing carrier unlock reach hundreds of posts - never seems to be an answer other than buy the device outright and request an unlock code after 30days. =/
Found this place that is supposed to be able to unlock TMOB's crapulance. I have not idea if they really can do it though.
http://www.androidsimunlock.com/phone-unlocking-service/tmobile-device-unlock-app-official-unlock/
unlockbase.com also advertises they can too, but when I emailed them specifically about the S7 they said they were not sure.
I'm wondering whether there will be an unlocked 64gb (or hopefully 128gb!) variant that could accept a TMo stock-based ROM & utilize WiFi calling & all TMo LTE bands.
I'm glad this thread was started, I'm looking to buy the tmobile s7 outright and was trying to figure out how I was gonna unlock it.
My tmobile s5 had an unlocked bootloader, I'm hoping for the same with the s7... Anyone know if the tmobile s6 came with unlocked bootloader?

AT&T or T-Mobile for unlocked S8+ ?

The backstory.... Preordered an ATT Note 7 and had many headaches with delivery / billing. I am now living with my old Note3 using Goggle Voice/Hangouts because of my weak signal (all carriers) at home. I'm using a pre-paid Straight Talk plan when away from home.
I've been waiting patiently for the S8+ and now need to decide between AT&T and T-Mobile for a GSM phone. I plan on paying full cash price and having it unlocked to use a 3rd part prepaid plan (Straight Talk or ?).
I considered a factory unlocked phone (Best Buy, May 9th??) but I am told that those will also have a locked bootloader. Up until the Note 7 I always ran rooted with custom ROMS. I became a big fan of Samsung Pay which I think also means a locked bootloader with no root is needed. Of coarse, bloatware sucks. I had good luck with Package Disabler Pro on my Note 7. I will be using my Google number, if only for forwarding to another number. WiFi calling is a must one way or another.
My Note 7 from ATT let me run Mobile Hotspot at the same time WiFi was enabled. This made it easy for giving my Android head unit in my car Internet access. The T-mobile version at the time needed to be turned on and off.
I'm leaning toward T-mobile only because of my bad blood with ATT. ATT coverage is marginally better in my area.

Either and flash the OS on it with ODIN. It is the same hardware so it doesnt matter.

Yes and also if the T-Mobile version is going to have an unlocked bootloader, flashing T-Mobile firmware should allow you to unlock it through the OS.
But it's highly unlikely it will have an unlocked bootloader, although T-Mobile have supported it, I don't think it's happening.

I get that if you buy a carrier phone and then unlock it. But what about the factory unlocked phones sold in the US?
I've heard that the bootloader on those phones is also locked, but not from a real good source of info. I've also heard international versions do not have a locked bootloader and do not support Samsung Pay. They also do not support CDMA (which doesn't bother me at all).

If I flash via ODIN does that kill Samsung Pay? What about Knox?

I'm in a similar situation and my first concern is what bands both phones support. Online it seems AT&T covers both GSM providers perfectly. The info on T-Mobile and its bands is extremely lacking. My second concern is the process of unlocking either fully paid off phone for use on the other. I think I can have TMobile unlock it for me but I'm not sure how it works with AT&T. The easiest solution is the unlocked version but thats not even got a release date set in writing anywhere.

As long you are flashing official firmware from Samsung nothing will break. Knox will not be tripped and Samsung Pay will work.

It is my understanding that all US (Snapdragon) phones cover all bands, including CDMA. That means you could even take an unlocked AT&T phone to Verizon. I'm not used to that! It even has LTE-U which TMo is supposed to be soon supporting.
I am an ex AT&T customer. They unlocked my Note 7, and again with the replacement, without issue. I seem to remember there was a wait period at first. 7 or 14 days?
The thing I'm considering is also the VR incentives for pre-ordering. I can tell you AT&T messed up my Note 7 pre-order. They shipped it on the release day by a slow method. I ended up going to a store and buying one outright and returning the unopened one once it arrived. That caused a billing nightmare that I had to call them every months until I finally turned it in and closed my account.

Can you recall where you read the carrier versions support all the bands just like the unlocked versions? All the info I found from the carriers shows different bands on each model.

You're missing what I'm saying... There will be no unlocked bootloaders on any Samsung S8 phones for the USA. You cannot get one from carrier or factory.
I think you may be mixing up Bootloader unlock and Sim unlock....

I do remember that it was a story about FCC approval of the factory unlocked (SIM) phone. Keep that in mind that it may be the unbranded, factory unlocked phone only, but the article did say they were all the same. The locked carrier phones may not be so flexible.
Other things I've found.. Best Buy SIM unlocked does not get the incentives. Best Buy, and their cheaper price, does not seem to offer a T-Mo phone.
The VR incentive is attractive to me, but is not a must have. At this moment, until I can find out for sure if Samsung Pay will work on an international version, I am leaning towards a T-Mo pre-order. But that is me and my preferences YMMV. I have a major dislike for AT&T.
Looking for where I read it. In the mean time this may be interesting to you.

It appears that going by this information the factory unlocked and the AT&T are NOT the same https://www.frequencycheck.com/compare-devices/6MQWs05y/samsung-sm-g950a-galaxy-s8-td-lte-samsung-dream/samsung-sm-g950f-galaxy-s8-td-lte-samsung-dream
You're correct that it seems T-mo info is evasive.
Hello,
I would like to know, if it posible to buy the Galaxy S8 from the samsung web page (att version), then unlock it and after that flash the unlocked rom flashing it with odin.
Can someone help me?
thanks.
Just ordered the 955F from Clove...
I'm hoping that missing bands won't hurt my AT&T usage much. Or any prepaid sims I may throw in there.
Will see if the 955U info comes out before my phone, and will decide if I want to cancel.

Relearning... software version questions?

Some of you might recognize me, used to be pretty active in the root/mod/ROM game back from the days of the OG Droid on, but have been away for a while. Now I've got a new Samsung S10E, and I don't quite get the relationships with the versions and trigraphs, etc.
My phone is a G970U1 - which I understand is a non-carrier specific unlocked model? But the Service Provider SW ver. reads SAOMC_SM-g970U1_OYM_TMB_PP0022 with TMB/TMB/SPR tags? What's the OYM? And what's up with the two T-Mobile tags followed by the Sprint tag? I did some digging around but couldn't see where there might have been a guide/explanation in this forum... pointers would be fine if it's too much of a pain to explain the whole thing here.
Also, OTAs? Would those come from TMO because of the tags, or from Samsung because of the U1 instead of the U?
Thanks....
For others' benefit: OYM is multi - covers multiple options depending on what SIM you toss into it. And the OTA question was answered a few minutes ago when I picked up the US Unlocked update from Samsung.

If you have an unlocked S10e model, then you shouldn't have SPR at the end. It should be XAA. For example if you put T-Mobile sim in your unlocked phone, it should read: TMB/TMB/XAA, meaning that you have an unlocked US model(U1). If you put another US carrier sim in the phone, then first 2 TMB/TMB will change to that sim, such as ATT, VZW, USC...but the third XAA will stay the same. If your phones shows SPR, then it should be Sprint branded model that was flashed with U1 unlocked firmware. Basically US carrier firmware has OYN in the Service Provider SW ver. and unlocked is OYM.

Thanks! That's exactly the kind of knowledge I was looking for.
So... my phone was somehow hijacked from Sprint and reflashed as unlocked somehow? It arrived in factory shape, including all the little plastic protective bits that you have to spend fifteen minutes peeling off, tearing open, etc., etc., etc...

It isn't an issue if the phone was flashed. So if you were planning to buy a factory unlocked model, then it isn't the case but nothing to worry about.
Back when S8 was a Samsung flagship, there was a news that Samsung is planning to make the firmware more universal(at least in US) and if you have a carrier branded phone and you put another carrier's sim, then it would automatically apply that carrier's settings + download any bloatware.

Question Does the regular unlocked version work with Verizon or do I have to buy 'unlocked' through Verizon?

Just wondering if the regular unlocked version supports mmwave or if I have to buy through Verizon. This gets on my nerves now.
Unlocked should in theory work with all carriers unless a carrier does certain odd things that couldn't be included on the "catch all" unlocked devices.
From what I can see it should work with Verizon phone and data just fine. Only the Verizon model it looks like comes with UWB (Ultra Wideband) though since that's Verizon's way of doing things if that interests you.
If you want that, will mean that you will have to have carrier injected junk though and buy the carrier version, get updates from the carrier, and have to have it unlocked by the carrier or sell it if you switch carriers. It will probably need to be unlocked by the carrier to put a custom rom on there also if you wanted to go that way. Its win and lose.
Coming from someone who just got the Verizon variant, it is indeed loaded with bloatware. It is also completely locked down from flashing roms or unlocking, verizon removed the oem unlock option entirely from their variant. So you can't even Odin flash to the unlocked firmware. Also the unlocked in the US is $349.99 right now versus $499 from Verizon directly. Although if you really want that UWB 5G then your only option is the Verizon model. Though imo not worth it. Go for the $349 one and enjoy it.

So I got the 349 one and it works with 5G was pleasantly surprised when I saw the 5G appear on my cell. All reps said phone compatible and the 5G Sim etc etc
Transferring device was painless.
I love the phone. I'm coming from using an Axon 7 never had a samsung phone before but like it. Got rid of a lot of samsung crop but customized it the way I like.
Thanks for your reply!
This is US market specific. For the A53 5G, any of the US carrier versions (with the exception of Tracfone) SIM unlocked will work on any of the big 3 carriers. Most of the versions (including Verizon owned Visible) are A536U, which is the version with Sub-6. A536V is the Verizon version with mmWave. I don't know what A536D from Tracfone is. Yes, you can get Sub-6 5G on Verizon.
But if you want to bootloader unlock, whether you are directly purchasing from Samsung or any SIM locked versions from carrier, it is not possible. See https://forum.xda-developers.com/t/psa-there-is-no-oem-unlock-on-us-galaxy-a53s.4443189/
I can confirm that the unlocked US version purchased from Samsung DOES work with Verizon. And like b1283822 said, does have/support Sub-6 5G, no UW.
