Galaxy SM-930V compatiable ROM? - Samsung Galaxy S7 Questions and Answers

I have SM-930V. US Cellular will not activate because this phone is not in their unlock policy. I want to flash firmware G930R4TYU4BQE1 the phone is qualcom.
will US Cellular firmware work with the Verizon S7? Please post link with your firmware suggestion.
I did have this phone on the US Cell network a few months ago but I was experiencing signal issues. Data worked fine, but voice service was mostly unavailable.
Thank you!

US Cellular is an off-shoot of T-Mobile? I believe that is GSM.
I went to Verizon last week, and they advise they are only CDMA. I think that is incorrect, but never the less that is what I was told. I purchased a sim chip and put into my A&T compatible phone. No go. I put it into another device that works with GSM chips, and though the device saw it as a Verizon service chip, it did not get any service. I am in a really terrible spot for cell service.
I read that Verizon was coming out with GSM service, maybe earlier this year? The service reps I spoke to do not seem to be aware of it.

You can only flash G930V or G930U firmwares to the Verizon G930V model S7s

I have a U.S. Cellular on Verizon but I was converted recently from Alltel. So I actually got the U.S. Cellular TP2 activated on Alltel then was brought over with the conversion. Everything seems to work except when I boot to Android data is flaky but use to work fine on Alltel they have an open ticket for me. Give them a call and talk with a tech to get it activated. Just don't say anything about it being a U.S. Cellular phone and you might get luck. If they say its not a Verizon TP2 then disagree and ask them to force it through. We are suppose to be able to take our devices from one carrier to another as long as its CDMA to CDMA technology per FCC order. Verizon also joined the Open Device a few years ago so it should not be a problem. Good luck!
Oh but mine is still all setup for Alltel...must be a grandfather thing but at least on Windows Mobile everything still works. I tired to configure it for Verizon but data did not seem to work. And mine still says U.S. Cellular as the carrier....wish I could get that to go away.

i dont believe g2x has 850mhz UMTS HSPA

I am from Vancouver bc. I am on the Bell network. Which operates from HSPA network only. Rogers is the only provider in Canada to have both gsm/edge and HSPA networks operational.
I bought a g2x, branded tmobile on the front itself and unlocked from a trusted source that I have repeatedly bought phones from. I get a new android cell phone every two months or so. Im familiar with setting up apn and so on.
The bell sim I use cannot find the bell network upon any kind of search. I can only find Wind and Mobilicity networks and they are AWS. I've tried reseating the sim and so forth, all fail. The sim works fine in my unlocked at&t atrix and Telus milestone.
I borrowed a rogers sim and it was able to register on the 2g network only. I entered the rogers 3g apn but it would disconnect when I put it on wcdma mode. Im convinced that either I have a broken umts radio or a faulty unit or tmobile screwed up. Looking for suggestions please and thanks .

imma keep this too about 3 lines if i can....
it has to have 850mhz its stated by the FCC that it does... (google specs)
and if it didnt... tmobile would have a law suit.... please if you will give us this "trusted source"
and when did you get the G2x?
I'm sure Tmo didnt lie, the phone has to pass the FCC in the US for the bands they will use, so Im sure Tmo knows what bands it's capable of. they wouldnt mismark the box.
Sounds like whoever unlocked it didn't do it properly maybe.
interesting...
only reason i was interested in the phone was the fact that it supported UMTS HSPA and AWS. wanted to use it on rogers but also wind down the road.
I got it this afternoon. The source is a guy I know that buys devices from the states and brings them up to sell. I bought several phones from him his year. I only wish this worked. The unlock definitely works or otherwise it wouldn't work on ROGERS' edge network.
when you put in #*#*4636*#*# into the dialer, what options do you have under Phone Information?
any options for WCDMA only?
Are there any *# codes that have been figured out for the G2x that might get you to a "Select Bands" menu? Maybe all you need to do is find a special menu and turn on the bands.

not to call you a liar but even if your "source" ordered the phone friday with the saturday shipping... how the **** did you get it through customs in one day?
just dont understand how you got the G2x unlocked from someone that buys them in the states and had it shipped so fast....................................
i shipped a 3 oz package to Toronto and it took 4 days... FROM WISCONSIN?!?!?!?!?!
Since ATT and Tmo haven't merged yet it could be locked out of the baseband right now too- to be unlocked by a software update after the merger.

if the merger is even accepted... LG would do all the hassle to lock a baseband till a merger happens that might not happen for 10000 reasons

Well that's the point, its still a year out at least. There'd be no reason to have a carrier branded phone unlocked to those bands yet until if/when it does happen.
If so it was a Tmo decision. And itd be a simple radio update in the form of an OTA update to unlock the bands, nothing too major.

very true but most phones/devices that carry dual basebands are not locked to a carrier that i know of
There are lots of variables though. The baseband software may have just not been ready yet. They may want to keep it locked pending approval of the ATT deal, merely was put there are a precaution to not have an outdated device if it does go through.
Too many variables, but it for sure has those bands. Anyone can go to the FCC page and look up the tests.

but i wanna know how this guy got a unlocked G2x from a "source" in the us so fast... faster than anyone of us ordering it.... (mine comes tomorrow when the sun is highest in the sky)
@dgr8one, let me check that out in the dialer.
@nate420, iwish I knew how he got it up so fast. I confirmed with him Sunday morning that I wanted it and he said unlock code probably be ready by Wednesday. Then he texts me today to say it's ready. Lol

damn must have held someone at gun point to get it the 15th lol <---- joking
It's too early to freak out, one person in Canada's having an issue with one G2X. T-Mobile would be insane to advertise the phone as quad-band and allow the media to report it that way if it's not really offered. If they didn't advertise it, but it had the capability, that would be another story. I'm sure a bunch of people are going to try and use it on AT&T over the new few days/weeks. Let's see what happens then.
I sincerely hope that whoever ordered for at&t purposes that it's only my device having issues.
I tried the #*#*4636*#*# but it only shows "mobile network not found ". My sim card is in there. Perhaps they will unlock the basebands somehow on the 20th.........

Sprint galaxy s5 question

Straight Talk, maybe, or similar that uses Sprint's network. It won't work on anyone else's network, so you're stuck there. Your phone has a CDMA radio for telephony, and AT&T and T-Mobile (and their MVNOs) use GSM, and Verizon locks their network down to registered IMEIs. I think some devices can be used on Boost or Virgin. Flashing shouldn't be necessary, but having it carrier unlocked is. Do some googling. Anything more that I could tell you you can find out for yourself.

Sprint + 955FD not compatible, no wifi calling

Bought 955FD myself here in saudi.
Followed instructions to make "cumulative 5 minute call" with middle east/north africa sim: regional unlock.
1st issue: wifi calling available?
Searched settings for wifi calling. Initially something pops up, such as an option but it asked for ?phone number? I dont recall, was too excited about getting ready to pop in sprint sim from edge6.
During this search i was waiting for smart switch to execute bringing files from edge6.
When its all done i see nothing about wifi calling on 955FD.
2nd issue: activating 955FD to Sprint network.
Called Sprint, they asked for HEX gave them the IMEI number, then informed phone is not compatible.
They informed me i could go into sprint store and have them flash the device to place it on sprint's system. But that didnt sound confident. The phone is not compatible but can be flashed.
I was told once before by sprint international they have special sims to be used on foreign devices. But after failed activation informed me the international sim would not work either. I am never satisfied with first tier help/information from sprint.
I am open any advice. Last hope is to switch to TMobile which i read in another xda forum it will work. But i am concerned about the wifi calling mainly.
If you're rooted, then flash the CSC selector and select TMB. It will bring you wifi calling and Volte in TMOBILE, Not sure Exynos model will support Sprint CDMA..
I'm using it in Tmobile.. Mine is G955F

Not rooted. Never tried that before. Trying to stay away from that effort.
Must it be rooted to be used on Tmobile?

As SBR said above, Exynos does not support CDMA. Sprint is CDMA. Your rep was correct.

Thank you. Would them offering to flash the device be worth a try for experimental purpose?
No. The Exynos chip does not support CDMA. That is only in the Qualcom chip. The problem lies in your CPU, not software.
You have two different types of cellular networks, CDMA and GSM. Sprint and Verizon use CDMA while everyone else (in the world) uses GSM.
Kind of just an FYI, in which case your phone will work on T-Mobile, but not sure about the extra steps with WiFi calling (though, if it's on these forums, then you should be set there too).
Will update about wifi calling feature after I speak to Mobile in few weeks upon returning to stattes.
Thanks.

WiFi calling on TMobile requires the TMobile firmware (which isn't available on the 955FD model, obviously).
Even unlocked US phones from Samsung can't use WiFi calling on TMobile unless they flash TMobile firmware.
You cannot flash the TMobile firmware on your device.

So my only option is to use DIGITS app by tmobile. Not bad but overall happy with my choice to buy this model...so far.

Getting AT&T features to work on unlocked S9+

Does anyone have a definite solution to this problem? I've read many opinions but haven't run across a solution. I have a Samsung unlocked S9+ running official AT&T firmware and userdata but the carrier specific apps and features still don't work. The best infomation I've found is that the IMEI numbers of the unlocked devices are not in AT&T system so the features/apps won't work.
If this is the case, has anyone had any luck getting AT&T to register their IMEI and get the features working?
What worked for me and others (see the at&t fw thread) is to call or chat with AT&T and give them a imei from a carrier branded phone(with your sim in, though this might not be required). Tell them you are trying to get wifi calling to activate and it is failing at the provisioning step and they will input your imei and it will reprovision. Then pull your sim and put it into your s9/+ running at&t fw and it will allow volte, wifi calling and call protect to work (these are the only ones I use).
Good luck
I talked with someone in AT&T technical support and they remoted directly into my phone, reset all app defaults and network settings.. This of course didn't fix anything so they opened a trouble ticket. They told me my IMEI was in their system and was OK. Haven't heard back yet.
why not just flash ATT U firmware?
I'm running AT&T official U firmware G965USQS2ARF4. What just occurred to me was that I didn't do a factory reset before or after applying it via ODIN.

Yes your IMEI is in their system. But it's not an IMEI from a branded ATT phone. You have to have the IMEI from an ATT phone like others have said, and like i had to do or you will not get the features, no matter what firmware you flash. This has been discussed in many threads. You have to have ATT change your IMEI in their system.

Wont help unless you have a 965U or the IMEI from an ATT phone . ATT Features will not work on 965U1 IMEI. AT&T told me theses features wouldn't work on an unlocked phone and asked if i had the unlocked version. I told them no, it was an ATT phone i bought from Best Buy and it has an ATT logo (not the truth, got it from Samsung) and that i read in the forums that there were some issues with the S9 and that changing the IMEI fixed everyone's problems. I said i had my s8 here that everything works on and she said it's worth a shot to try and she changed mine in their system to the IMEI from my AT&T Branded S8 that i provided them. 965U1 has worked flawless ever since. All features work.

sounds about right.. i mean you can switch csc while on U1 depending on the sim card inserted but U1 isnt meznt to have all the carrier crap they need for the special features to work so u get the bare minimum..
while on U firmware, it seems the csc doesnt fully switch like they did on the S8 devices.. i tested this on my sim unlocked vzw s9+ with an att sim and a sprint sim and although data and calls worked,it stsyed on verizon bootani and bloat etc etc no matter what i did.. before on s8 devices after a reset it would have changed the boot ani,bloat and woulda had all the carrier features..
im also surprised they changed your imei lol.. i thought that was illegal lol.. i guess if the carrier does it then its fine haha

Hard to believe that they would just accept another IMEI and register it to your phone. I thought these were all unique numbers that couldn't be used on more than one device. How did that change affect the phone that originally had the branded IMEI?

Didnt affect original s8 i used at all. or the s9. I replaced the s8 with the s9 when it came out so i just used the sim out of the s8 when the s9 arrived. s8 is just a spare phone now. I asked the operator if this would disable the other phone that the IMEI came from and she said no. I put sim from s9 in s8 afterwards just to test and it worked fine. They arent changing the IMEI of your actual s9, it still shows your original IMEI in your phone settings. They are just using the IMEI you provided on their end. What is actually going on behind the scenes i dont know. Maybe somebody that works in carrier support or may just have knowledge on how this actually works could chime in. I'm guessing they just use the IMEI to activate the features, since the unlocked one isn't eligible. I saw a better explanation in one of the firmware threads, if i run across it i'll post the link.

I will reiterate what is said above and clarify my post. You aren't asking the support team to change your phones imei. I think as stated previously that is a forbidden/illegal maneuver. The support request is to change the imei which is active in the at&t system as only carrier branded phones are able to use certain at&t features.
If you have an old AT&T phone its imei can be used to "trick" at&t into activation/provisioning. Then you can put your sim into a U1 phone using at&t firmware and use carrier specific features.
Hopefully, this is easier to understand and clears up some of the confusion I may have introduced in my original reply.

I presume I can use the IMEI from another brand of working AT&T phone such as an iPhone 6S (in this case, my wife's)?

Another thought... Say I get an old Galaxy S6 which uses the same size Nano SIM as my S9+. I move my S9+ SIM to the S6, update it to the latest AT&T firmware and enable WIFI calling. If I then move my SIM back to my S9+, will the carrier features now work?

This is exactly what I'm doing. I use an older LG phone and the sim/IMEI then swap it to my u1 with AT&T fw after the device is provisioned.

I previously had an AT&T branded S8+ with the same SIM that I'm using in the unbranded S9+ but I guess I never provisioned (enabled) WIFI calling. Dunno.
The "trick" of giving them an IMEI from an ATT branded phone doesn't usually work any more, maybe it used to, years ago.
This is why I won't buy OnePlus phones any more. I love their devices, best bang for the buck on the market, but no amount of my fiddling would get ATT to recognize it and provision VoLTE... so no wifi calling, no HD calling... when you make a call, your data drops to 3G, etc...
My Essential, somehow was on their "BYOD" plan and so it would give me VoLTE and HD calling, but no wifi calling. No wifi calling is stupid, because you aren't using their network at that point, so why should they even care?

"maybe it used to, years ago"... That doesn't apply in this context does it as carrier features VOLTE and Wi-Fi calling weren't even in existence years ago. And I'm not sure you have to give them anything. The claim by some is that just provisioning the features with your SIM on a branded device is enough.

And as someone who has repeatedly tried it, it doesn't seem to work. You can give them an IMEI from another phone, but it usually doesn't work. Either the IMEI is "on their list", or from a phone that is on the BYOD list, or it isn't. It's not the phone's fault, it is that AT&T is kinda being dicks about this... They want you to buy their phones, because most people sign a contract to get the cheaper price, or use their NEXT financing to spread the costs out. That creates a barrier to exit for most customers and protects AT&T's revenue stream from monthly invoices.
While bringing your own device makes them just as much money from the monthly bill, it doesn't help them "retain customers by locking them into a contract", so they usually don't give you full functionality...
I have had a working SIM from an ATT branded phone that was properly provisioned, popped it into my other device, and VoLTE went away. I would call them up and give them the IMEI from the phone, or one that I know worked, and still no go. The one exception was the Essential, and that was because for whatever reason, Essential went to the effort to get it on their BYOD list.
Trust me, if it was easy, I would be doing it and buying OnePlus phones exclusively every 6 months and that would be the end of it. LOL
