Unlocking More Bands?

Hey!
From what I've read online it looks like all S7 Edges are built identically which means that the bands must be controlled by software. Are there any firmwares, patches, or tricks that enable other bands? I have a Verizon S7 Edge on T-Mobile so I'm mainly looking to unlock band 12. I saw this post: http://forum.xda-developers.com/ver...e-flashing-sm-935u-firmware-verizon-t3415145/ but im not sure if that will unlock the bands or not. VoLTE and WiFi-Calling would be a plus.
Thanks.

So you mean like flashing the u firmware or something

I believe that is what this post describes: http://forum.xda-developers.com/ver...e-flashing-sm-935u-firmware-verizon-t3415145/ but I dont know if that will actually unlock the bands or not. Have you tried it? Will it actually unlock the bands?
Thanks.

I haven't tried this but my s6 edge works for my gf on metro and it's a Verizon phone with of1 firmware. I don't see why the u firmware wouldn't work for you.

Flashed the U Firmware. It didnt unlock the bands. Any other suggestions?

Maybe now that you're on the U firmware you could flash the T-Mobile firmware? Not sure if it would work or not, maybe you'd be willing to try. Make a backup just in case...

I do belive the band's are controlled by the baseband/radio file in the updates, of course most of my experience is with the ENG bootloader on HTC devices so I think for Samsung it's either modem or pda....more experienced members can correct me if I'm wrong, so feel free to jump in

Do you think flashing the T-Mobile firmware would help? I posted in the other thread asking if it would work but if flashing firmeware replaces everything (bootloader, os, kernel, etc) then it should work right?

SM-935V

I would like to know if it's possible to flash the firmware for
T-mobile I'm looking to leave verizon I know that the Verizon variant does not have 2 of the lte bands that T-mobile uses can I use Odin to Flash the 935t firmware to get the band's or am I asking something that is not possible. Thanks in advance

The answer is NO you're asking firmware to replace/add hardware and that's not possible

I have a Verizon branded s7 edge and used Odin to load the 935U PI3 firmware. I am on T-Mo now and do have LTE band 12 working (validated with LTE Discovery). The research that I did found that the US variants have all the radios in them, but some carrier variants of firmware disable certain bands. By doing the 935U firmware, I also got rid of the notice on every reboot that I was using a non-Verizon SIM. So I now have all T-mo bands and no stupid SIM message.

I can vouch for same experience as SF-IT guy. I bought a G935V and flashed with G935U firmware via odin. Works on T-mobile, even wifi calling works. Currently on the latest PI3 version of G935U firmware. I would that you search the forum to see if you can flash the G935T firmware directly. The only downside of using G935U firmware is that the FM radio chip is not enabled in the firmware. I read that the all the carrier versions (September security patch and newer) of the G935 firmware have the FM radio chip enabled. I prefer the 935U version because it there is not carrier bloatware. Samsung bloatware is still there.

So what would the FM radio chip do? Just enable FM radios is all? Because if that's the downside then it's not a major setback as not too many people use the FM radio.

I don't think you can

You definitely can. All US versions of the S7 & S7 Edge are the same hardware and can be flashed to any other US firmware. (including the U firmware that automatically works on all 4 carriers)

So what you're saying is that flashing the U version firmware will unlock by default all 930"X" and 935"X" phones? As in it just unlocks the mofo and debloats some while you're at it?
What's the catch? It seems too easy

Bloat is definitely gone on the U firmware, which is great. My phone runs faster and has more free space too.
I think some carrier features aren't supported on the U firmware. On T-mobile everything works (VoLTE and Wi-Fi Calling), but I think AT&T might have some issues with those.
If the phone is SIM locked to a particular carrier, I'm not sure that automatically gets turned off or not when you switch to the U firmware. You might need to contact your carrier first to get an unlock code?

What if I got a temporary unlock from t-mobile unlock app and then flashed this firmware? Would it make it permanent? Seems quite possible, but I don't know if the temporary unlock actually unlocks the phone or just inserts a bypass that would disappear if flashed.

I unlocked my US TMo phone when stock, rooted, and am running Echoe - which has a glitch where WiFi calling sort of works (can receive calls but not make them). In the TMo forum, there are threads on U - your comments here are more specific to what I am interested.
Which U firmware are you on and are you rooted (is is updated to latest v4 bootloader version), and did you have to ODIN and full wipe with CSC or did you get by with CSC Home to preserve data?
Also, are you on U CP or did you flash TMo CP to get all the bands?.

Nougat for SM-G930U firmware?

I'm on a Verizon s7 g930V running Samsung's stock firmware g930U and I've read that the phones bought through Samsung (so no carrier to go through) are getting Nougat OTA already.
I'm rooted, so it obviously gets mad if I try to check for an OTA, but should I unroot and check for a nougat OTA?
Do we know of anyone trying this successfully?
Does a Nougat Odin install package exist somewhere with "g930u" in the beginning of the filename?
Let me know if I should bother guinnea pigging on this one.

No need, I just checked and there's no update. Nothing online about it either. Seems only the international models are getting 7.0 at this time.

930/935 U is on quarterly updates. There will likely be no Nougat till April at the earliest.

so is there any possible way of running nougat on sm-g30u?
am i able to flash sm-g30f firmware on this to get nougat or is this not possible as they are different models?

The F model is the international version and it is not compatible with the US unlocked S7. You can however flash any US carrier version firmware on the the SM-G930U.

thanks, are they any known issues in smg930u like the ones i raised earlier?
seems very buggy in australia. Microphone is also recording muffled and louspeaker calls echo on my listeners end and no noise cancellation

getting frustrated with the device, network is bad, any possible way of flashing the baseband from a sm-g30F to a SM-G930U?
I need the network more reliable. Now i regret not checking the model number before buying the phone

EDIT: Neverfmind, figured it out.

I'm trying to figure out which image to download for T-Mobile USA?

What's the difference between USA(XAA), USA(TMK), and USA(CSC)?
http://updato.com/firmware-archive-...1&r=TMK,USC,XAA&v=Nougat(Android+7.0)&rpp=100

If you want full T-Mobile firmware with T-Mobile apps, logo and other features, then you need TMB. XAA is for an unlocked Galaxy S8(my S8 has it)

It depends on the model. If you have an unlocked US model, then WiFi Calling, VoLTE and Band 12 are already supported. My model of S8 is G950U1

I just realized that all three versions USA(XAA), USA(TMK), and USA(CSC) of the most recent July 28, 17 version for the S8

I think it might be a mix + carrier needs to support and device needs to be whitelisted in their system. Which model do you have or planning to buy?
XAA will contain most US carrier's CSC codes, so this what US unlocked model comes with.
TMB is for T-Mobile, which is the same as sold by T-Mobile.

You need to download the G950U1 firmware. It is the unbranded firmware. It has all the T-Mobile firmware but none of the bloat or boot logos.

I have a Straight Talk S8 and I'm done with them. I want to use my phone at T-Mobile next. But my phone doesn't have the WiFi Calling feature listed anywhere in settings?
I was think of flashing a Tmobile image?

If you put T-Mobile sim card, then go to phone app and access the settings and then check if you see WiFi Calling there. To find out what you CSC is, just download Phone INFO app(Samsung) from play store. The launch the app and swipe to the left to go to CSC section.

USA(XAA) is an unlocked version that works with US carriers.

Here is the most simple answer I can give all of you with this. Look at this thread. https://forum.xda-developers.com/tmobile-galaxy-s8/how-to/eng-boot-root-t3608353

Right, I had that question myself before, but you have to make sure which model you have and what is the CSC of your phone. Carrier versions should be: G950U, but US unlocked is: G950U1. There is a little difference in XAA and others, but if you really want unlocked that would have CSC codes of most US carriers, then use XAA image. It will allow you to put any US sim card in the phone and it should work.

I would suggest checking out the carrier switching threads here. There are several... One here and at least one other I think in the T-Mobile S8 guides forums section, that walk you through changing the firmware to the US unlocked while keeping carrier features.

You will need to download the USA(XAA) firmware. That will give you the unbloated version and you will have WiFi calling and volte with T-Mobile. Just type in sm-g930u1 and select the XAA firmware. I have full T-Mobile capabilities with that firmware which is the US Unlocked model.
Make sure to use the regular csc file and NOT the home csc file.

S8 active update

It is to ask i am having an unlocked s8 active with different carrier and out of usa... no ota here i am able to get and stuck on May security patch.. can somone suggest a way to pull updates as site is listing 2 more FOTAs more there.. will greatly thankful

You cant get otas outside of the usa on the phone its impossible. I did however just upload the dec update to the guides thread. You can flash that.

I doubt it, i would assume it needs to connect to att towers, it probably checks the sim too. But truthfully i have no idea, i just highly doubt it. Updating us phones overseas has always been done via odin and sideloading.

can I use this firmware over the AT&T S8 Active?

You're looking at the SM-G892U model. OP has the 892A. I wouldn't flash that unless you know they're interchangeable and also want a bunch of tmobile apps on the phone.

I've tried but even patched odin couldn't flash
