[Q] Best buy "unlocked" galaxy s5: unlocked bootloader?

I've been an iPhone user for 5 years now. 3G and 5 versions. I am tired of iTunes I would also like to tinker a bit with my next phone. . I have used Linux as my main desktop os for a few years.
Anyways, I'm on a grandfathered unlimited data plan on att. My iphone 5 has no working power button, the mic is defective and the battery is worn.
I work in construction so i was considering the s5 for its dust rating and removable battery.
I spoke with tmobile today and they told me that any tmobile device, even if bought for full price new on amazon or best buy would be locked to tmobile service. They informed me I would need service with them in order to unlock. If that's the case it rules out buying a tmobile version for the unlocked bootloader.
Does the unlocked version from bestbuy come with the unlocked boot loader?

To clarify I meant the model listed as "Sam G900"

Go into settings and in "about device" for the model name. Sam G900 is not a model name.

I'm pretty sure he's just going off what best buy says for the model.
I too am wondering this question. Very disappointed in the new S6, thought it was going to be "the next big thing", turns out they just want to be like apple now.
Side note, where would u recommend buying an unlocked bootloader S5, that has LTE capabilities for att? Or does that not exist in the US? Been searching but coming up empty handed.

I don't have the phone I am referencing. Like mentioned earlier, it's just the model number off of best buys webpage. They have the g900a model and a Sam-g900 for sale. They only sell the tmobile prepaids unlocked at a higher price point.
Is there a reputable online seller of new or refurbished unlocked tmobile versions?
I don't know if I wanna gamble buying used.

Buy a 900f from ebay. There are tons of reputable sellers there, just look at their feedback score. All qualcomm models support all lte frequencies, however they're not activated by default. There's a guide in general or q&a which shows how to activate all freqeuncies

Does the 900f come with unlocked bootloaders? Is there a way you can identify if they have an unlocked bootloader without physically checking the phone just don't want to spend hundreds of dollars and kinda get stuck with a phone that's not what I wanted.

I just purchased an unlocked GS5 G900T (Tmobile version) from eBay yesterday, and should have it by the end of the week. I've purchased my last 3 phones from eBay, and all have been true to the ad, and in excellent condition.
You do need to study the photos closely though, and make sure the seller has good feed back, and a lot of feedback (I never buy from sellers who have only a few ratings and/or using a new account).
I got this phone to use with ATT and wanted an unlocked bootloader. Kinda wish I knew that you could activate the frequencies on the 900F though, as it seems like most of the development is for that model. Oh well, as long as I can root and have a few choices of ROMs, I'll be happy.
I'll probably be using some sort of stock based rom on this phone (for a while at least).

ok cool, thanks for all the help!!
I did not know that T-Mobiles Galaxy S5 Came with unlocked bootloaders. I am just going to get one from them since T-Mobile and ATT run on basically the same LTE Basebands and LTE will not be affected as much as the international version when i'm on ATT's network

didn't read the rest of the replies but cricket...they sell it with unlocked boot loader, and you can sim unlock after six months...but they are owned wholly by att so you'll have att's reception and reliability. Of course your unlimited data would be history but crickets rates are significantly lower than most other mvno carriers
Edit: the model no is sm-g900az

I called bestbuy.com customer service. The customer service agent was no help. No additional info than what's provided on the webpage (actual samsung model # is what I was looking for).
She transferred me to their technical support department. The gentleman spent about 5 minutes or so searching and couldn't come up with anything more.
I was told to call an actual best buy store and speak with their mobile department.
I called later today when best buy opened up. Sat on hold for 8min before an actual human being answered the phone. They too were no help. The conversation went like this...
Me: do you know which model of the g900 the sku 5760005 is referring to. . The listed model number Sam-g900 with that sku# is not an actual samsung model number.
Them: it's a g900.
Me: no you do not understand, g900 should be followed by one more letter. Is it a g900a, g900t, g900v, g900f, g900h, etc?
Them: it's a g900. What provider do you have?
Me: I'm on att but probably going to tmobile soon.
Them: we don't carry tmobile. I have a g900a. It works good. (they have the prepaid tmobile s5 on their website).
Me: nvm. Thanks have a nice day.....click.

Best place to buy Exynos version in US

Like the title says, what's the best place to buy unlocked international phones in US.
I also might have an option to buy while traveling to UK and looking for suggestions.
Will be using it on AT&T.
thanks!

The US has Snapdragon, the UK has Exynos

thanks for the eye opener, now back to my question "Best place to buy Exynos version in US"

In the past, I've had the best success with well rated ebay resellers. Having ebay back your purchase is important because they are so buyer centric. If there are any issues at all, they will force paypal to refund your money. The only downside to this, is that you'll likely pay a little more - especially if you purchase right at release time.
Wonda Mobile and Expansys are also great/reputable online resellers that will surely sell the S8 and S8+. You'll pay closer to the retail price of the device (no ebay fees, price gouging, etc) and their return policies are good. That said, YOU will pay return fees back to Korea if there are issues and you're 100% at their discretion for returns/replacements/restocking fees, etc.
Hope this helps.

I got my Galaxy S7 Edge (G935F) on Amazon and was going to get the NOTE 7 EXYNOS from https://www.bhphotovideo.com/
They are a good retailer - I am hoping we can get preorder from them - (they did offer a preorder for the NOTE but it never happened because batteries started exploding before the NOTE 7 Was released.

Silly question - but why would one prefer the Exynos version over the Snapdragon? Is there a noticeable difference in performance, or some other factor?

From what I hear, the performance on the Exynos variant is better than the Snapdragon variant. Also, the SnapDragon variant has been bootloader locked as of lately (Note 7, S7, and S7 Edge) while the Exynos variants have been unlocked.

So I pre-ordered a sim unlocked s8+ through samsung's UK site. not sure if they will ship to US though

Greetings from Canada,
Would anyone know which "soc" goes in the Canadian variant?
Thank you.

thats so naive from you..see the galaxy s7 exynos variant was unlock the past year where the s7 820 was not, what that means ?
basically means that you was not able to root any western device , but only exynos variant can... and root a device is crucial to open a lot of possibilitys like overclock
and responding to the question of this guy, basically in every latin country on america you can find the exynos variant, which is kind a weird cosidering that allways all america used the qualcomm variant in the past , and because a lot of mexicans carriers dont have the culture of wait until the oficial release of the smartphone i will expect some people to buyit long before

Canada is getting the snapdragon like the USA unfortunately.

Handtech and Clove are both reputable UK shops that many on this forum have used and recommend. Be aware if you're​ a first time buyer at either you may have to jump extra hoops to clear your credit card. This is normal and due to the high degree of fraud in international cell phone sales​.

BH has it listed now, but just to notify when available. It has it listed as SM-G955. It doesn't say whether or not it is SD or exynos though.

I know with the international S7, Samsung Pay would not work in the US. Not too worried about that, but are there any other drawbacks? Will it work on all the LTE bands for AT&T?

I think for those that really want the international version, you'll have to find overseas sites that ship to the US or get them from a reputable seller on eBay such as never-msrp. The downside, as always, to importing is a higher price and generally, no warranty. I generally get quarterly trade where if anything happens and no one fixes the phone, they'll just give a full refund of the phone price. Anyways, just make sure it says SM 950F or SM 955F. The F are the true international unlocked models. Samsung pay may now work in the US. Check out the S7 threads to see how they got pay to work in the US

The s7 had all AT&T and tmobile bands. Volte didn't work and wifi calling also didn't work on tmobile tho even though the s7 had band 12. It just would not connect. I now have att so that's no longer a concern with me

I contacted the UK samsung web page and the sim free version still need to make a 5 minut call in the uk first to be truly unlocked, as it has region locked.

Check out clove UK. They have the cheapest pricing for the S8 and the s8+ and you get the international model. Picking mine up Soon

You don't want them to ship it. The EU phones have region lock. To use a SIM from a country different from the phone's selling country you have to make a 5 minute call on a SIM native to the selling country on a network native to the selling country. That's why all the grey market phones on eBay are mostly from Asia.
Here's an article on it.

LTE on ATT works fine on the International Varients - the only thing missing is WIFI Calling and VOLTE - if those are big deals for you, yoiu need to stick with an ATT Phone. I haven't missed them - LTE speeds for me have always been great - I don't need WIFI Calling - and HD VOICE, well, I am not so sure it is everythign it is cracked up to be - call quality for me has been very good - so I personally am not missing anything.

I have wondered for a while if the snapdragon model in the US isn't something paid for by the NSA to be a the only US variant offered. Like more backdoors, etc built in to the Snapdragon variant. Unless there is some other obvious reason why the US gets only the Snapdragon variant.
It really doesn't matter for daily usable or noticeable performance however. Bet you'd never be able to tell which variant you were using if they were set up the same and you didn't check in the settings to cheat to see which variant it was.

Single universal model for the US?

With the Galaxy S7, it was a single model variant that was dictated by the carrier software installed. What's the likely hook of this happening again with the S8 or do you think it'll be like the old days where each carrier has different hardware?

Single model for US it sounds like.

Yep, SM-G950U model for S8 and SM-G955U model for S8+. According to Best Buy preorders for unlocked version starts on 5/9 http://www.bestbuy.com/site/clp/samsung-galaxy-s8/pcmcat1489428710715.c?id=pcmcat1489428710715

SM-G950UZSATMB - What!? Bootloader unlocked?

I see this BOGO offer direct on Samsung's website for Galaxy S8's. In the past, all Galaxy S phones were SM-G920T (T for T-Mobile) SM-G920V (V for Verizon, etc) and then Best Buy sold that piece of crap SIM unlocked SM-G920U that was bootloader LOCKED and couldn't do anything with it.
I'm trying to find out here if the Bootloader is locked on any variant of the Snapdragon 835 S8's, and which version I should get. T-Mobile has the same BOGO offer on the S8 in the form of a rebate as well, but I can't confirm anywhere the specific model number. I'm so jaded by the fact that T-Mobile left the bootloader locked on their S7 that I can't imagine them leaving it unlocked.
The G6 is also BOGO right now as well, but I don't know if that bootloader is unlocked like all my previous LG phones from T-Mo we're.
I'd really appreciate any kind of confirmed answers you might have!
Cheers!

All the carriers have "U" devices in the U.S. this year. The SIM you initialize the phone with is what carrier's features are added. A "U" from Samsung apparently doesn't take on the carrier whose SIM is used features and remains virgin. So "U" could be considered "universal" or "U.S." It's still a S-835 device which means "U" definitely doesn't mean unlocked bootloader.

I'm not an expert at all but I really doubt that ANY Samsung bootloader will ever be unlocked again. Pretty much after 2013 all bootloaders were locked [AFAIK] at least for the Galaxy series. I really like Samsung devices but my Galaxy Tab S (late 2014) isn't even going to get the Nougat upgrade - this actually pisses me off greatly.
When you see 'unlocked' concerning a phone/device it means CARRIER unlocked, not the bootloader. The 'unlocked' means that you can use it with any carrier that the device supports - so just about most of the carriers/providers in the entire world. Still not sure about this concerning CDMA (Verizon/Sprint) as some things may not work (different bands). Tried using GSM phones on CDMA a few years back and wasn't able to use 4G/LTE & also MMS.
Good luck.
EDIT:
Was typing this as BarryH_GEG replied to your question. Yes the letter following the model corresponds to the various carriers (Verizon, Cricket, Sprint, etc) and are also different for international versions.
EDIT2:
On another note I own a Galaxy S7 Edge (international) that has the Exynos processor that is unlocked. At the same time this is the only device I've never rooted because it works so well for me, no carrier bloatware. Also the only device I've ever purchased without a removable battery. Until the latest updates I was able to go 2 days without charging (not anymore unfortunately). The international S8/S8+ also use the Exynos processor so you might consider this option. However the cost will be high as it was for me when I purchased my GS7edge as you'll need to purchase it directly without any US discounts or such. I paid out just over $700 for my GS7edge directly, though at the same time my AT&T bill is much lower because of this.
I've researched the GS8+ international and it's looking to be around $800. Compared to trading in my GS7edge international for an unlocked US version I can get for $375 (with trade-in) if I do this within a month or so... I can probably get $400 for my GS7edge (since it's international) but how long will this take? If I only get $300 for it for a quick sale I'll still spend $500 for the new 8+ so is this worth it?
Only stating these issues so that you understand my thinking concerning an unlocked bootloader. These are [mostly, still SS stuff] bloatware free, have incredible power, etc, etc. I miss rooting my device but is it really worth it for the cost? I really want the international/Exynos S8+ but still not sure.
Let me know your thoughts, later.

LG V20 US996 Variants

So I got burned on ebay on two separate US996 phones. The sellers never stated a provider and just said factory unlocked (some on ebay actually say US Cellular) so I naively assumed they were the same as the unlocked version B&H photo has been selling.
However after buying them I found a thread on how to tell the difference and the factory unlocked should say USA under the battery. However, the phone I got says UCL (which I think is US cellular) and my wife's phone says BPL (no idea what provider that is).
So, I am wondering if I should just keep these at this point. I paid $268 for my wife's phone about a month or two back and $250 for mine a week ago, so not a terrible deal, but I could have gotten an AT&T unlocked version for not much more new.
So anyway, these phones don't come with any carrier bloatware which is nice and why I'm considering just keeping them. I don't really care about rooting, however I am concerned about 2 things: future updates and cellular bands.
Does anyone know what the differences are hardware wise between these 3 variants or is the only thing that's different the software?
If it's just software shouldn't there be a way to flash these with the real factory unlocked firmware?

Here's a page with the latest ROMs for each variant of the US996:
https://lg-firmwares.com/lg-us996-firmwares/
The BPT one is the BrightPoint version.
The odd thing is that the US Cellular version of the US996 has a much newer version of firmware than the USA Factory Unlocked US996.

Interesting. It looks like the US Cellular firmware works on the unlocked version so I guess there is no difference. I wonder if that means I can flash my wife's phone with the US cellular firmware as well. Never heard of brightpoint.

not sure how true it is, but if you flash the US Cellular firmware on the unlocked version and try to unlock through LG then it would no longer be recognized as the unlocked version. that said you can unlock first and then flash... which is what I did so I can't confirm the former to be true
