Help? How to switch from ATT to Verizon software on S8? - AT&T Samsung Galaxy S8 Questions & Answers

Can someone please list the steps for flashing Verizon software on ATT S8? I do not want to use the unlocked software (need mobile hospot to work).

Search for threads started by me. I posted the latest QK5 firmware from my Google Drive. Flash it and since it's an all carrier update if you have a Verizon sim it will install all the VZW features.

BTW, idk where you read hotspot doesn't work but I usually run nothing but unlocked and it's never not worked.

[Q] N910T on verizon networks

I see the general consensus is that the tmobile note 4 cannot be used on verizon. Is the radio purely software controlled? Could I just flash another baseband and modem?
I did notice when I installed cm12 and inserted my verizon sim I was able to get 4g and data access but not on the stock tmo rom. Voice did not work as well. Is there anything I can do? I dont really want to have to shell out for the verizon version with an unlocked bootloader.
Thanks

Which G930U firmware for Sprint phone on Verizon network?

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....

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.

Installing AT&T firmware on unlocked Verizon S7 Edge SM-G935V

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.
Clicking from Edge of Galaxy.
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.

Been out of the rooting/flashing scene for awhile..

I'm still using my tmobile gs7 edge and I would like to continue doing so, but I will be going to xfinity mobile and they use Verizon...i bought a pair of burner phones to activate service...
I've read that simply putting the sim in wont work, that I have to flash the verizon firmware or "U" firmware, but I'm seeing a lot of bootloader 4,5,8 and such. I'm not sure what to do.
I'm currently on the latest tmobile oreo stock 8crj1 firmware. Is flashing still possible? Or am I sol? Anybody that can guide me in the right direction? I appreciate it
Well as an update, I was able to figure it out. But in the event someone else has the same issue.
935U firmware does not work with Xfinity mobile.
If you would like to use your own byod for Xfinity you will need to install the 935V version. (Verizon)
Everything works as it should.

Latest firmware/ROM to use for Verizon on Tmobile S7E (root preferred)

I have an old Tmobile S7E on old ass firmware (Android 7.0 BQE1) and it's already rooted. I just went through Tmobiles Device Unlock process and I believe the phone was unlocked successfully. I'm looking to upgrade to the latest firmware that still allows rooting. I've looked through the Custom Roms threads and can't tell which one is the latest. I am also wondering if I need to use Verizon firmware or stay on Tmobile firmware.
For instance, this thread here: by jrkruse, he mentions to another user in the comments "This one or verizon one? This one just has the Tmobile csc stuff added and a build.prop for gsm carriers thats it" so it made me wonder if I'm using Verizon service but it's a Tmobile phone if this would work. I know Verizon is CDMA so him saying gsm carriers made me think it may not work.
I know this device is old and this thread doesn't get browsed as much anymore so hopefully I can get some answers. If I can't get this working I guess I'll just be getting a new 2020 model phone :highfive:
Thanks guys!
