Hi all.
I have a G930P just unlocked (USB/hardware method via GSMZambia). Currently has older OTA-restricted ROM to allow the unlock.
I'd like to update to the newest G930U firmware to get rid of all the Sprint stuff.
We are Verizon (USA) customers, and will uset he phone on the VZW network. I have already confirmed this works after the unlock (using the SIM from my own VZW S7).
Question is:
Which G930U firmware do I use? on the download pages they are specified for Sprint, Veriozn, AT&T etc.
Do I use the G930U for VZW because that will be the carrier? What is teh difference between these, I assume it is the splash screen and which radios are set as the default?
Thanks
Wanted to follow up on this.
After some careful comparison I realized that ALL the "u" firmware files listed - for each of the different carriers - are in fact all the same file. Which make sense b/c it's intended for a phone that starts off life w/ possibility to go to any network.
So after putting the "u" firmware on my formerly Sprint phone, it works flawlessly on Verizon. As far as I can tell all the relative radio bands are working equally well as my other G930V (native Verizon) phone.
Hopefully this will be helpful to somebody else in the future....
who did you get lte and voice to work. for some reason i can only get one or the other to work. not both

I didn't do anything special at all.
I literally installed the reference ROM, and it worked. It has since auto-updated itself several times, and works flawlessly.
It's my wife's phone, I have a G930V w/ Verizon firmware etc (never done anything special w/ it) and the function the same. Just a few skin differences where Verizon has added extra stuff to mine AFAIK.

I have a Verizon HTC 10, which I have converted to US Unlocked and run LeeDroid, which mostly works, but it requires me to dial *#*#4636#*#* to select radio after every reboot.
I plan to stay on LeeDroid ROM, so don't need or want to take OTAs. I just want everything to work, including Samsung gear for my watch, advanced calling (HD calling mainly), visual voice mail and Android pay might be nice.
Now that Verizon firmware for nougat is available and I could convert back, dues it make sense? Is there any advantage to running US Unlocked or Verizon version? LeeDroid ROM provides everything for Verizon to fully work (or will very soon), so is it just fine to install the latest Verizon firmware and radios onto the US Unlocked version?
If you're just gonna use the phone on VZW, common wisdom states you should stick with VZW software, especially if/when Nougat is now available.

That's not required...LeeDroid has always run perfectly well on Verizon firmware and not needed any dialed codes like that.

The latest version of LeeDroid has Advanced Calling working for most Verizon users. For some reason, it's not working on mine, but there are reports of it working perfectly for a handful of other folks.

It's been discussed on here before (can't remember which thread, sorry) that it's always better to use Verizon firmware + radio when on the Verizon network. It's tweaked to work the best with Verizon's towers and signal.
It might be overkill, but since you are coming from US Unlocked firmware, I'd recommend using the full Verizon RUU and starting from scratch. That way, when you flash LeeDroid, you don't have any funky remnants of the old setup.

Yeah, but it wouldn't be 'sticking with' VZW software, it would be re-converting back to VZW software, which isn't so cut and dried.

Actually, no, it doesn't work perfectly well on Verizon if your using nougat firmware, the codes are required.
However, it does seem it is all working great now that we have VZW firmware for nougat, so I will probably convert back now.
I just wanted to see if there was any other reason to stay on US Unlocked, but it seems there isn't.
Off to find the no wipe firmware now.
Thanks for all the feedback.

I've purchased an unlocked Verizon S7 Edge, model SM-G935V, but haven't received it yet. I'm an AT&T customer. The phone should work on AT&T's network since it's unlocked, but I just realized it'll probably still have Verizon-ified firmware, and might not work with certain AT&T-specific features like HD voice, video calling, or voicemail. How will the Verizon firmware behave when it's on the AT&T network? Can I install the latest AT&T firmware on this phone instead, using a similar method to what people are doing for the 935U firmware? I prefer a stock AT&T firmware rather than a beta or rooting. Thanks in advance!
There's another thread in this forum "Stock Firmware for SM-935A (AT&T)". Should I just flash that to my unlocked SM-935V, and essentially turn it into a 935A? I believe the hardware of all S7 Edge models is identical, so I'm hoping that will work.
I did this and applied the 7.0 update - and now I can't seem to revert to any other software. If I were you, I'd flash the U update and forget about carrier-specific garbage.

Thanks. Did you have any problems getting LTE data to work with your 935V once it was on the AT&T network? I saw a few mentions from people saying they could only get slower data connections, until they called AT&T to "provision LTE for their SIM" or something. I get the impression it's not enough just to have an AT&T SIM card - like the AT&T network has a registry of phone IDs, and non-AT&T branded phones won't be in it, and so won't get LTE data.
From browsing the 935U thread, it sounds like that firmware is receiving updates much more slowly than the carrier-specific firmwares. The U firmware also wouldn't provide the missing AT&T-specific features I was looking for, like HD voice or WiFi calling, so I'm not convinced it would really be an improvement over just keeping the Verizon fw. But maybe I'll feel differently once I actually get my hands on the phone and play with it - all I'm doing now is reading forum threads and checking my mailbox.
Honestly couldn't tell you. I'm on Verizon with my main device (S7e on U FW). I only flashed the AT&T FW (PK1) so I could flash the unreleased Nougat files.
Now, I can't seem to flash anything but an AT&T rom.
Also FWIW, the U firmware is getting updates slower than carrier roms, but it's still the better rom - untouched by the carrier's bumbling idiot of a dev team, no pre-loaded carrier junk you can't get rid of (only disable), better battery life and better performance.
More FWIW, I don't care about HD Voice or Wifi calling - both those are irrelevant to me.
At&t release today on 2/17/17 official update to Nougat 7.0 build BQA6 with February security.

I want to do the opposite - flash G935V onto G935A, with the intention of eventually being able to flash back G935A. Not sure if I could do this, though.

I've got my phone working now. The short answer is yes, as far as I've found, you can flash any carrier's firmware to your S7 Edge. There may be some limitations if the bootloader version on your phone is different from the new firmware's bootloader version, but fortunately I didn't run into that. I went from the Verizon firmware to the AT&T firmware and then to the unbranded 935U firmware.
But for best results, a branded S7 Edge should be used with the same branded firmware, and on the same network. Otherwise you may run into some problems, or certain carrier-specific features won't work. In my case, my Verizon-branded S7 Edge is unable to get Wifi calling and HD Voice (aka VoLTE) on the AT&T network with an AT&T SIM card, no matter what firmware version I use.

Really? That's strange. I successfully flashed V firmware on my A and HD voice & WiFi Capping are active

So you did the opposite direction of what I did? I've read that AT&T is more restrictive about these features than some other carriers, which is maybe why it didn't work for me. I can't find it now, but there was an AT&T community forums thread in which a rep straight-out said that those features won't work on a non-AT&T-branded phone or other unlocked "bring your own device" phone.
To be fair, I'm not certain HD Voice isn't working, since there doesn't seem be a definitive way to test for it. With the AT&T firmware, attempting to turn on wifi calling would give me an error saying it couldn't be activated on my device. With the unbranded 935U firmware and an AT&T SIM card installed, I don't even see an option for turning on wifi calling.
I just picked up a used s7 edge from a at&t customer, every thing that I could find said once unlocked it would work on any network. I unlocked it via at&t, checked that it works on an at&t sim and Tmobile but it is not working on my Verizon sim and their techs can get it to work either.
Will an At&t s7 edge work on a Verizon network? if so how? Or should I find a different phone?
Thanks
Andy
That is an interesting question. I believe all the US based Snapdragon S7 and S7 Edges have the same hardware, so you would just need to flash Verizon or unlocked firmware over the AT&T image. That part is confirmed, as people have gone from V to U and A, and A to U and V. If I were you, I'd probably go for the unbranded firmware, but that's a personal preference.
The real trick is getting Verizon to properly provision it.
At&t is gsm and Verizon is cdma not compatible with cdma you need to give carrier imei that's how cdma works not just with SIM card

The US (Snapdragon) S7 and S7 edge share the same physical hardware. There is a better than average chance that if he flashes the U or V firmware, and can get Verizon to put on their network, it will fly.

Question: to convert from one firmware to another do I have to install U first? I want to convert my G935T to G935A to be able to use wi-fi calling. My phone is unlocked and everything works on At&t except for wi-fi calling (Or VoLte as I see it referred to often)

If this is your first device with AT&T to support WiFi calling, you may have to get a new SIM (or get your current SIM provisioned correctly).
So are you saying I don't need to install the G935A firmware?
I have a rooted a s7 and rooted note 3 (both at&t) and trying to use both on the sprint network. I managed to sim unlock both and still can't connect either to the sprint network. Is it possible to even use either?
Perhaps if you use the modified version of ODIN floating around and flashed the carrier-unlocked or sprint ROM onto your S7 you could get it to work (IIRC all S7s in the US have the same hardware, just different ROMS to support different carriers)
The Note 3 has no chance of working. It's missing the correct radios.
I will say this, while I think technically the S7 has the hardware for it, and you could technically use it by flashing another ROM, Sprint may still not allow you to use it because when they try to add it to their system via IMEI it will come up as an AT&T phone, and they will likely deem it incompatible.

Yep after digging around that's the same conclusion I came up with. I'm just gonna end up getting an unlocked phone with all the proper radio bands. Thanks nonetheless

The above link indicates the G935U phone as having more radio bands than the G935A
I am confused if I flash my S7 Edge G935V to the G935U (AT&T) do I end up with exactly the
same radio bands as a G935A or do I have the bands of the G935U as shown on this site?
Where I was told to download the 935U firmware I see no choice other than pick a 935U for a specific carrier as for
example AT&T. However the G935U on the above list has more GSM bands than the G935A.
Can someone clear this up for me?
Thank you,
Ken
All of the US variants have identical hardware - as in, there is physically no difference between an Unlocked, AT&T, Verizon, T-Mobile, and Sprint device. You can swap between all the carrier firmware versions (and the unlocked variant) at will with the right version of ODIN. Obviously, Verizon and Sprint make it a bit harder to bring a "foreign" device over, but if you could get it registered, your A device with V or S firmware would work.
HOWEVER, each carrier customizes their devices for their networks, and one of those modifications is to turn off support for channels that they don't support. If you look at the missing channels, you will see that AT&T doesn't use them. Thus, the A firmware turns them off. (This also keeps you from taking an unmodified AT&T device to Verizon - which uses 13 for their LTE)
I haven't tried, but I believe installing the U firmware should restore those frequencies.

2 phones are shown. 935U on the left and 935A on the right.
The 935U has more network bands. But it doesn't say if it is AT&T, T-mobile associated like all the download firmware
I have been looking at.
Is there a different version of firmware for the 935U shown in the link? If I install the 935U (AT&T)firmware do I end up with a AT&T
with no bloatware and less bands than the 935U (Left side) in the link?
This has me puzzled. I would prefer the bands to the one on the left side. It would appear to me
to be more compatible with GSM along with it retaining all its CDMA capabilities as well.
Could use some help clearing this one up.
Thanks

I decided to go for it. The first to attempts led to a FAIL. The 1st FAIL put the phone into a boot loop. The second try FAIL.
I tried the latest ODIN with a Patch. This time it worked and all went well.
What I am so far is a little disappointed the CDMA feature no long exists like it did as a 935V.
I was hoping that was not the case with the 935U firmware. The good news is I am now connected to band 12.
On the final boot up after flashing the phone instantly found AT&T band 12 and it also automatically added the correct
APN settings for straight talk with their AT&T sim. There was also a couple AT&T APNs and 2 straight talk APNs.
The one chose as default is working with text messages. I have not tried sending a text with video yet.
Thanks to all who offered me a little hand holding during this process. It was a little scary especially when the phone
starting the boot looping thing but I just tried again and on the 3rd try with the patched version of ODIN it worked.

Help describing this firmware and its features.
On this site I found this firmware
https://updato.com/firmware-archive-select-model?record=05B44581906411E89F15FA163EE8F90B
The Product code is Product Code USC and when I did a search on it I found it to be
USA unbranded. The Samsung Galaxy S7 Edge G935U has CDMA and GSM capabilities with more
GSM bands than the G935A. Would anyone know any info on this firmware and what you end
up with when flashed to a S7 Edge?
Thanks,
Ken
