I have a SM-930V(verizon) galaxy s7 and is running Tmobile(930T) firmware. Is there any tmobile sim-unlocked firmware that I can download? Or can I flash the 930U firmware and sim-unlock my phone? What are the implications on doing this? I want to keep samsung pay, wifi calling, and LTEvoice.
You need to get a sim unlock code - there are a few websites you can purchase that from. It is not a firmware change, at least not on the S7.
Correct me if I'm wrong but don't Verizon phones come GSM unlocked or is that only for outside of the country?
Verizon S7 comes unlocked: http://www.androidcentral.com/yes-verizon-galaxy-s7-and-s7-edge-are-sim-unlocked, Just Flash the latest SM-G930U Firmware available. as always at your own risk of course, plenty of guides on how to flash the U firmware to verizon s7 here at XDA.
My T-Mobile S7 came with a device unlock application... Ive never seen it before, so i tested it out by using the temporary unlock and it worked...

It works. A tmobile rep confirmed that it is now unlocked.
If you do not have the apk for some reason... i grabbed it heres the apk:
mines is factory unlocked (SM-G930U) so am good to go , congrats on unlocking it and you can now flash the SM-G930 U firmware on it and get rid of the TMO bloatware.

I bought an AT&T S8+ from my friend and I unlocked it.
I was wondering if it was worth the hassle to Carrier Switch and then flash Unlocked firmware?
My CSC says ATT/ATT/ATT but I mean it works on T-Mobile and I heard the last 3 are permanent so even if I carrier switch, it'll be TMB/TMB/ATT or something like that.
What does carrier switch even do?
Can I follow this method even though my model number is SM-G955U and not SM-G955U1?

I buy my S8+ on Sprint and flash unlocked firmware and for me, it's worth, only lost VoLTE but i really don't care about it. gain more user space because unlocked firmware have less bloatware and I think it have more battery life. I didn't make any carrier switch.
Sorry for bad english haha. And yes, doesn't matter, you can flash it safe.

AT&T, it's stuck on the May security patch.
I had an att s6+ before and used it oversea. I never got any ota updates. Only hope is Odin. You may want to att s8 forum to confirm.
Looks like it is my only hope. What exactly is Odin and do I flash a carrier one or a stock one. Then if I do the stock one do I get normal updates.
Possible for anyone to link me to a guide on how to flash this unlocked AT&T s8+ to a factory unlocked one or a Three-UK one? Also by doing this will over the air updates start working.
I think att locked the bootloader so no you can not flash other carriers rom. Sorry.
I have a Sprint-branded S7. It's unlocked. I want to switch to T-Mobile.
Sprint changed its S7 bootloader to v5 in November 2017. All other carriers, including T-Mobile, are on bootloader v4 or earlier.
The problem: You can't flash to an older-version bootloader. You'll just get an error. The phone has efuses that prevent it.
Are there any workarounds?
Specifically, I want to switch this S7 from Sprint's G930PVPS5BRA1 to T-Mobile's G930TUVS4BRA1 (bootloader version emphasized).
No work arounds I've ever seen, US snapdragon models are all bootloader locked which prevents you doing any major modifications at a firmware level.
You'll either have to wait for a v5 of the firmware you want, or try the carrier unlocked G930U v5 firmware which might work better with T-Mobile.
I believe this is also the same for the unlocked bootloader on Exynos models, but only if you get the newest drag firmware version.

Unlocked is also on bootloader v4: https://www.sammobile.com/firmwares/galaxy-s7/SM-G930U/. That is why I suspect this v5 bootloader is a trick by Sprint to frustrate switching.
Booloaders are all locked on US S7s you can not switch Stock ROMs
You could SIM unlock and use a T-Mobile SIM though (paid)
Or sell that phone and buy a tmobile one

This phone has the domestic unlock by Sprint, so I can switch stock ROMs. I did exactly that last summer when Sprint and T-Mobile's ROMs both had v4 bootloaders.
Because it is unlocked, you are right that I can also put in a T-Mobile SIM while it has the Sprint ROM. However, it will not see all T-Mobile bands until I put T-Mobile firmware on it. I noticed that last summer, and there are other anecdotal reports of this on the internetzors.

Pretty certain that all bootloaders on the US model S7s are locked meaning you cannot switch stock ROMs, other than Verizon to the G930U, maybe others to that U firmware, but I don't own the snapdragon variant so just going on what I've read here on XDA
All Snapdragon US S7s are bootloader locked, meaning no custom anything
As for certain bootloaders of each stock ROM I don't know
But I do know SIM unlock and bootloader unlock are two completely different things, switching from one carrier ROM to another does not unlock the SIM to that carrier

They are locked against unauthorized/custom software, but there is nothing that stops you from putting authorized software on them. As all US variants are hardware-identical, all carrier ROMs are by definition authorized on any.

I see, but what would be the point of switching from Sprint to T-Mobile stock ROM?
Surely just different OEM bloat?

While the hardware supports all bands, the ROMs do not have all bands enabled. From personal experience last summer, if you have the Sprint ROM on the phone, your phone will not see all T-Mobile bands. There are plenty of anecdotal reports of this on the internet.

I was under the impression that only SIM unlocking would solve that?
So you are saying that by managing to flash from Sprint to T-Mobile, a Sprint S7 is now able to use the T-Mobile network without a SIM unlock ?

SIM unlocking only appears to permit you to put your phone on another network. It does not appear to enable all your phone's bands. To enable another network's bands, you appear to have to switch ROMs. If there's another way of doing that, I'm interested!

My guess is you would first need to perform the actual SIM unlock, and then move over to the preferred network ROM to have 100% of their bands and abilities
If your phone was originally on Sprint, and you managed to flash to T-Mobile, my guess is that your T-Mobile SIM would still not work until you SIM unlocked
CSC change is what determines which features work and don't, for example on o2 CSC I can get WiFi calling, but with XEU (also UK ROM) I cannot, even though my carrier is o2, basically I bought the phone on XEU but unless I switch manually over to O2 CSC I cannot use that feature

Yes. Another way of putting this is that SIM unlock and band unlock are different. Sprint can unlock the SIM and let me put other carriers' SIMs in my phone. However, that doesn't unlock all the bands. That is only doable by flashing that carrier's ROM. Due to Sprint's curious choice to upgrade its bootloader, I am locked out of doing that.
I have previously been in a state where my CP was from a different-version SM-G930U ROM, while the rest was from an SM-G930P ROM, and I got repeated "Security notice" warnings from the Samsung software.

I am somewhat experienced in this but not enough to be sure. I have sm-g30U factory unlocked by sam and got oreo update and hate. How may I check my versions or rather where might I find the proper software to downgrade to nougat . I dont understand why people keep saying "930U sprint, or vzw" . When its unlocked its not any carrier only the carrier you happen to use as its a dual sim right ? though today im with vzw i may not be tomorrow. Anyway can i flash backwards , I saw a few videos where it was done on sammobile and if not I would love to get any info in rooting it to help my battery not liking the oreo so i can help at least with bloatware. any help would be appreciated

There's two types of unlock.
* Bootloader unlock, which allows you to modifies the phones boot partition. It's required for custom ROM's and recovery.
* Carrier unlock, which is just whether your phone allows any SIM or only a specific carrier.
The G930U is carrier unlocked, you can use any SIM, but it's still bootloader locked like every other US model S7, which means no boot modifications.
As a result you can't rollback the G930U because of the locked bootloader, and you can root it but only but using an engineering bootloader which comes with many side affects.
Does only the number matter or does also the letter? For example, say Im deciding between U5 and S5, how would the efuse work?

Yes just the number , cell carriers tend to use the letter S while Samsung unbranded tend to use the letter U. But the number tells you the version boot loader .
Hi, I have a problem with my note 20 ultra and I would like to know precise info because is very important. I live in Italy, and I buy a note 20 ultra sm-n986u in the USA to get the snapdragon variant, which is much better of the version selled here in Europe. The phone was At&t locked, but the seller give me a code to unlock it to insert my italian sim. All is working well, except the fact that the phone never recieve updates due to the fact that I'm not in the USA. So I need to flash a new firmware with odin. So this is the problem:
1) Should I flash an n986u firmware (with At&t bloatware)? In this case I will lose my unlock code?
2) Can I flash a n986u1 firmware to de-brand the phone from At&t? In this case I will lose my unlock code?
3) If I lose my unlock code, will the same code work again?
I searched in theese forum an answer, but no one can give me a precise information, only hypothesis. I think it is a very difficoult argument, but it's very important to me. Can someone help me? Thanks.
Flash it with U1 firmware and it will do auto update. you won't lose the unlock.

So basically unlocked phones are brand phones (att, spring, verizon ecc) in which someone already insert the code? And it stays forever?

Ok thanks! Then I will flash U1 firmware if I it keep unlocked. Tell me, does in USA companies uses 4g+? My note stays only on "4G LTE", while my old phone used to stay with "4g+" network.
I have an unlocked T-Mobile S22 Ultra, but I can't stand the boot screen and all the bloat. Is there a method to flash a unlocked firmware on T-Mobile variant? From what I understand we can't OEM unlock toggle on these.
What I did was, I got the U1 t mobile version firmware from sammobile, did a clean flash, and everything is working good, I believe you have to chech that the firmware you're trying to flash has the same baseband as the one installed in your phone. Also you need the latest patched Odin version to flash it.

Can you look to see if your Sim Card Manager is any different than the one outlined in this post (https://forum.xda-developers.com/t/sim-card-manager.4410867/)?
It's the same, except that I only have a physical Sim in my phone. I don't use eSims.
How much bloat are you seeing? I thought T-Mobile bloat was fairly minimal.
A shortcoming I noticed when I flashed to the U1 firmware was you can't RCS with AT&T contacts anymore. Minor inconvenience, but still an issue.
I guess my T-Mobile bootloader is U2A? I don't see which is the compatible download for that.

Everyone loves to run debloat scripts with no real knowledge of what they're doing, then complain that their phone is acting up and giving errors.
I swapped firmware for T-Mobile U1 u2a. Will I still get updates? I had the same firmware just not U1.
So theres no way to flash "global" firmware on a Tmobile S22 ultra? I hate Tmobile boot screen and updates are not the same
Hello, i got a phone but it's tmobile locked, how do i bypass first activation screen and ultimately unlock for WW use
If you still owe for the phone (even promotion) it cannot be unlocked until it is completely paid off. If it is paid off, you will need to contact T-mobile to have them unlock it.
Thank you, is there a way i can see if it's paid off or not?
