I flashed my S7 Edge with the US Unlocked firmware so I could use it on T-Mobile, and recently I sold it on Swappa and advertised it as running the unlocked firmware so it could be used on any carrier. The buyer is using it on Verizon, and said he can't get Verizon Cloud to work, and isn't getting voicemail notifications. Is there anyway to get this to work short of flashing the stock Verizon firmware?
I think the buyer may have to root the phone to get Verizon cloud working. Similar to getting Verizon voicemail working on the 935U firmware.

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.
Do not use the stock Sprint software Numbers will not come formatted correctly when you receive phone calls.
For instance when you get a call it should show like this.
+1-808-123-1234
But on the Sprint software with a non Sprint Sim Card it will show like this.
+808-123-1234
So anyone who's saved in your contacts it won't show there phone number. And you also can't easily call them back from your call log.
And this also prevents blocked numbers feature from working correctly.
If you flash the unlocked firmware or you flash the carrier firmware of your choice this issues will go away.

Hmm, maybe this is why Google Voice can't send mms for me? I'm DSU'ed on G935P and using a Mint SIM (T-Mobile). When I try to send a mms from Google Voice, it says mms can't be sent to international numbers.

Sim unlock.
So if I flash the unlocked firmware. Will this affect my sim unlock that I just paid for?

Nah it wouldn't reverse the unlock status, I'm 200% sure it wouldn't change anything. I personally unlock and flash the latest G955U1 and G950U1 firmware AQH3 on 6 S8+ and 1 S8. It's works great on All US carriers, you can also flash each 4 individual Carrier firmware. I have flash all of the firmware each carrier release on my SPRINT S8's with zero problems. Enjoy
Were did you get their stock firmwares? Looking for,sprints and you used a modified Odin to flash?
Hi, I'm trying to get my unlocked sprint s8 plus to be used on Verizon but no luck so far. Is this even possible.. Any advice would be appreciated. Thanks

Hello,
There is no root forum on here. How did you find out how to flash?

Did you ever get your phone unlocked ?
I have a Sprint Galaxy S8+. It has been unlocked by Sprint. I am giving it to my daughter and want to change the firmware to MetroPCS firmware for her. I have the latest T-Mobile and MetroPCS variant firmwares. Do I need a special ODIN to perform this? I'm a little confused because I keep seeing discussions about modded ODIN versions for the Galaxy S8 and S8+
I'm on Verizon and I don't want to switch carriers but I also want the perks of having a factory unlocked phone. Can I buy the Verizon s8 and then change it to the stock unlocked g950U firmware?

Today the wife and I jumped ship from Verizon and brought our own S7 Edges(935V) devices to Tmobile. My phone is running the 935U Android 8.0 firmware already from Verizon and works great on TMobile service. Her phone on the other hand is G935V on official Verizon firmware still. Her phone works great on TMobile just as mine but her phone is still on Android 7.0 Verizon official. As far as taking updates now or reflashing with Odin,would it be safe to flash her phone with U firm from TMobile? Are all the U firms the same? Would flashing the TMo firmware help any at all with the tmobile radios and such? Any help greatly appreciated! Enjoying the TMobile service so far! Way better service here in Lansing,Michigan with Tmo than the Verizon.
I've used both the G935U and the G935T firmware on my S7 edge from Verizon no problem on the TMo network. People have said the U Firmware radio doesn't have quite the signal detection range as the others, but you might just be sacrificing a bar of service for more consistent connectivity.
Eventually I ended up using the G935T firmware instead because the TMobile bloatware helped my wife manage her account and such. If her phone was still on Verizon Official and needed flashed for a non developer, I would go with the Tmobile firmware just for less confusion.
The Verizon S7's really were never carrier locked in the first place, and the S7 has universal modem firmware.
I bought a replacement S10+ for my AT&T account. I got it from Samsung and chose the Unlocked version. Come to find out, it appears the unlocked version does not support AT&T NumberSync. I have a Galaxy watch that I wanted the NumberSync feature with my S10+. Can I download an AT&T firmware and flash it to my phone to have it work with the AT&T features such as NumberSync, VoLTE, etc. Is it as simple as just downloading the AT&T firmware, launching Odin, rebooting phone into Download / Odin mode, selecting the files and flashing? Thanks.

If you can find the AT&T firmware to flash you should be able to switch. The problem is that unlike Sprint, Verizon and T-Mobile AT&T apparently doesn't release their firmware to third party sites like Samfirm and it isn't available to download on the XDA thread with carrier specific firmware links.

I read the thread in this forum that linked the firmwares, and there was AT&T, but I'm confused now on the bootloader version. Do I have to flash to a SM-G975U then to an AT&T firmware, then to U1 again? idk. Also, I found this from a google search and downloaded it the other day, an AT&T firmware: https://www.sammobile.com/samsung/g...SM-G975U1/ATT/download/G975U1UES1ASDB/273101/
