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.
Babadebucci!
So firmware is your phone currently using? still the att?

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 .
Hey guys, I've got an unlocked T-Mobile s10e that I'm currently using with straight talks att sim. Service isn't that great at my house with att and my wife's Verizon gets all her bars. Can I just swap with the Verizon sim, or do I need to flash the Verizon firmware. I'm very familiar with Odin and flashing with the s6 and s5, but I do currently have a locked bootloader. If I do need to flash the Verizon firmware, which one do I need to use? I've been a member here for years but couldn't get into my old user name so had to create a new one.
Question. I have switched my carrier from Verizon to T-Mobile. How do I remove the Big Red branding/splash screen/apps and replace them with the T-Mobile stuff? Can it be done with a factory reset or do I need to go deeper?
Thanks
If you have a T-Mobile sim. Just call them and have them reprovision your phone. All they will do is have you turn it off, they will send a new signal. Once you turn it on, it should update to all T-Mobile.. I forgot on question. Is this a factory unlocked version? If so I do not think you will get much T-Mobile apps. I know I do not have that annoying boot screen, and that is how I like it..
I have a VZW branded device. I want to get rid if all the Big Red stuff. I'm even contemplating flashing the U1 firmware or the latest Tmo or their CSC. I just want to make sure I get the security updates ss I should and not get them from Verizon.

If you have a Verizon Branded, but a T-mobile sim, do as I suggested, or you should be able to flash the U1 firmware
Will do. Thanks
Learned something.
Samsung BYOD carrier update only works with carrier unlocked devices bought directly from Samsung. If you change carriers and want either their bloat or no bloat you must flash via Odin. Nice part is if you flash the unlocked firmware you can uninstall all the bloat. The jury is still out on OTAs....
