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.
Hi guys quick question I have a friend that visited me her to The Dominican Republic and decided to give me his Samsung Galaxy S7 Edge. The phone is actually unlocked to any carrier but my main concern is if he goes back to the US and report the phone as lost with Tmobile, will the lock the phone again? Or just make it as bad esn that way it can no longer be activated in the US..
Pls answer me ASAP, my friend is leaving back to the states tomorrow and we just want to make sure prior to he giving me his phone...
Thanks in advance

Network stays unlocked if it was a permanent unlock via Tmobile. (Not a 1 month temporary unlock sometimes done by Tmo). Even if it gets locked, it can be unlocked on ebay for a fee.
ESN will be blacklisted.

Thanks for you response but ebay isn't a option
If it's a friend of yours, why would he report it as lost if he's giving it to you? Doesn't sound like a friendly thing to do. Or are you trying to scam TMO somehow?

Thats was not what I said
This sounds shady. He's giving you his phone, then false reporting it stolen so that he can get a new one.
Either way, they won't relock it but the ESN will be bad. If it registers on a tmobile tower (even through a prepay service) it will kill the service because the phone's blacklisted through TMobile.
Ok I have been reading about this from multiple resources and haven't seen a direct answer to my issue so I wanted to ask the community here. I want to thank everyone In advanced for taking time to read this and help me out.
I purchased a US Sprint S8 from a friend. He's called them and they unlocked the phone for us. I am attempting to add it to my Verizon plan. They are giving me the run around stating the IMEI isn't compatible. I am not seeing how this is possible as the S8 is showing it's both CDMA & GSM compatible. One rep in their tech support stated they could add the IMEI into their database and that will help resolve this, which was two days ago when they submitted that request (48 hour turnaround). I follow up with them and they are telling me it's not CDMA compatible blah blah blah. Now, the other thing worth mentioning is that when I take my Verizon SIM and insert into the sprint S8, it states that it's not a valid SIM.
Anyone recommend what's the best course of action here? I'm not the most savvy person when it comes to dealing with Odin and rooting the phone. Worse case scenario I am going to drop this thing on ebay and try to recover my expense.
Have a great day!

The it's not CDMA is bull, Sprint is a CDMA carrier. The Sprint S8 also Supports Band 13.

what model do you have?
My understanding is only 1 model is sold in the US, the SM-G950U. Has CDMA and all the LTE bands used in the US. Carriers just add their own bloatware.
Maybe you need a specific verizon sim. I know sprint needs specific sims for certain phones.

I am thinking that you may need to flash the unlocked firmware(G950U1) to your phone, which is XAA. Unlocked firmware includes many US CSC codes that should be compatible with most US carriers. Your Sprint phone may only have its own CSC which could be SPR, but Verizon's CSC is VZW.
Check out this thread: https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817 Ask your question on that thread as well.

Based off reading that thread you mentioned that would make sense hypothetically. Would you or anyone be aware if I flash this and it still doesn't work, can I flash back to sprint and sell it as a standard sprint phone? Don't want it bricked or be out the $$ by my half ass attempt of acting like I know what I'm doing.

It is always a risk, but first I flashed my unlocked model to T-Mobile firmware(using regular Odin app), used it for 2 months and recently flashed back(using custom Odin app) to unlocked firmware before putting my phone for sale of eBay. I personally take the risk especially if it doesn't work for you with Verizon and don't see a reason why you wouldn't be able to flash back in case you need it. In other words if you phone enters download mode, then it should be able to flash.

Tried to flash to g950u1 tonight and it didn't help the SIM issue. Going to try the Verizon version and also as the store to give me a new SIM card. Hoping this works out soon
Appreciate the advice!
Hello all,
Like many others, I unknowingly bought a blacklisted phone on eBay. It's a Samsung S7 with T-Mobile from the US. I live in Costa Rica, and I'm trying to use a SIM from a local service provider. Sending the phone back for an uninteresting list of various reasons is impossible at this point. So, I am attempting to unlock it.
I rooted the phone with SuperSu thinking that would work, now I know better. After hours and hours of research, I found a xda dev that can remove the lock, but with my slow internet speed, he says it's impossible.
I was suggested to use one of the paid services, but I'm concerned that if my slow connection will not work for the xda dev, why would it work for a paid unlock service? My connection is 5/1. Anyone have any luck buying the expensive @$$ service and successfully receiving the code with a slow connection?
Is there really no way around the T-Mobile Unlock App?
Is there truly no DIY process or program that I can do, being that the paid unlock services may not to work?
I really need this phone to work. I just moved to Costa Rica, and I use my phone to work. So, I am pretty damn stuck between a rock and a hard place with spikes. I'm pretty desperate, almost willingly to pay my last money to a dumb unlock service.
But some of the services say that it will not work if the phone is blacklisted.
I just don't know what my options are at this point.

Might be able to resell the phone with a *disclaimer* that it is blacklisted, I would recommend Swappa over Ebay though, (I got a really decent chunk of change for my Galaxy S Blaze that I sold on there), and then use the proceeds from that to acquire a phone that isn't stolen.
I got mine unlocked in a repair shop at gaffar market,delhi,india for rs 3200 inr and it was blacklisted on tmobile's website, when bought it was unlocked but after few days it automatically got locked to tmobile.
I mean to say if i can get it done in india you guys can also get it done in your countries.
You would have to do a firmware swap - which you could do yourself - you just won't be able to use it on that particular carrier, even via an MVNO on that carrier. My own S7 is ex-VZW (network locked); but I could take it to T-Mobile (and did) via firmware swap. My carrier (Tracfone) uses both VZW and T-Mobile towers ; while VZW was out, T-Mobile, however, works fine. If you sell the phone post-swap, include documentation that a firmware swap was done, so the buyer does not try to take it to T-M by mistake - some folks insist on following the labelling unless expressly told not to. (My S7 still has VZW labelling.)

Firmware swap? So you're saying you can take a Note 4 on T-Mobile that is blacklisted and you can fix the problem just by flashing a new firmware from AT&T? Am I understanding that correctly or no? Because I have a Note 4 that is on T-Mobile that someone left at my GF's work and never came back for, so they wanted to throw it away, so I took it, I rooted it, deleted all the bloatware and have it working great as a small tablet, but I can't use it as a phone because it is blacklisted. Been trying to find a way to use it for years now with no luck, I will not dish out any money to one of those sites, I don't trust them. If there is a way I can do it myself I would surely try it.

A blacklisted IMEI only affects the blacklisted carrier in question - it does not affect ALL carriers. (I cannot take my Snapdragon S7 to Verizon or that side of Tracfone due the IMEI being Verizon-blacklisted; however, it does not affect T-Mobile or the T-Mobile side of Tracfone - which is a separate network/carrier - which is why I was able to take the phone there.
. In your case, your Note 4 has a T-Mobile blacklisted IMEI; therefore, you can take it to AT&T Mobility, Verizon, the Verizon half of Tracfone, or Sprint - you simply need the apropos firmware and SIM. If the phone itself has T-Mobile labeling/branding, and you are trying to sell it, you should include documentation indicating what was done, and why (honesty). The biggest issue is sellers that DON'T do that (document what was done) or worse - don't do a firmware/ROM change for a phone with a blacklisted IMEI. So you can actually use it as a phone - you just can't take it to the original carrier.

This is what I am saying - that and a SIM from a carrier other than the one that blacklisted the IMEI - I took my own phone from VZW to T-Mobile (Tracfone supports both carrier networks). Because it was an internal swap (same MVNO), it cost me nothing.
ok so i purchased 2 phones from a company here in the united states called SPECTRUM MOBILE....
i payed the phones off i have proof of ownership..
one is an Samsung S9+ the other is the Samsung S10+........
i used an unlocking service to remove carrier lock because spectrum requires you to use thier
service for 1 year before they will unlock i guess? CS rep was an asshat!... so i payed to have unlocked
i was able to get the s9+ activated on BOOSTMOBILES network with NO issues!
the s10 + i was not so lucky.... they only accept a global unlocked version of the s10+ bought directly from
manufacturer.... the rep for boost mobile was not much help in explaining why... he really didnt know anything!..lol
and there was a major language barrier which made the process even worse.... so i guess my question is..... can someone
help me understand why they wont accept it on the boost network..... and maybe a work around that can be discussed
that dont violate T.O.S. i have considered purchasing chimera tool or DFS ... is that a possibility or just a waste of money?
