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?.

Hello everyone,
yesterday, a family member gifted me an s7 from the USA (SM-G930P). He bought the phone off SPRINT as a SPRINT unlocked version, and, of course, because I live in Europe and want to use the phone with a European SIM card I have the "hands free activation" mark that is sitting on the top left edge of the display. I also noticed some changes, for example the "mobile data" toggle is nowhere to be found and also I don't have the options to choose the network mode (2G/3G/4G). I love the phone and I also would like to keep using it, I only need some answers from you guys.
My first question is, if the phone will actually let me use 4G network with my European SIM card, or will I be limited to 3G?
My second question is, If I can flash an international firmware for another carrier and another country on the phone, and if so, will I have the advantages of that firmware, like the Mobile Data Toggle??
Thank you very much for your answers.
If you install the 'Network' app you might be able to change the network type.
In general you should be able to use an unlocked P variant with a foreign SIM but you may have to activate with a Sprint SIM first.
You can't flash the international version since it's Exynos and the P version is Qualcomm CPU.
I am not sure if this model has Samsung region lock which is another thing to consider.
If I was you I would try to flash the U firmware (US unlocked) as it has the most support for international 4G bands among the Qualcomm US models. It also doesn't have all of the Sprint bloatware on it.

Thank you for your reply. I am currently using the European Sim from my carrier and I have no problems with it. I managed to get rid of the Bloatware by using Package Disabler Pro, but it still sits there somewhere on my phone. So far, the phone is working very well and other than the bloat sitting on my memory and the lack of LTE, I have no complaints.
Can you tell me if someone has tried to flash the U firmware on a P model with success?

I had bought an unlocked Sprint galaxy S7 (930P) off ebay which died on me. Got it repaired from the service center and they sent me a locked device instead. The phone is currently on Software Version - G930PVPS4BQC1 and the hardware revision is Rev 0.6. I'll be using the phone in India and have a few questions.
1. I need to get this SIM unlocked from a service online. Does anyone know of a reliable place to do so?
2. If I flash the U Rom on it after unlocking it, will I lose the unlock? (I don't mind downgrading from Nougat to Marshmallow)
3. Should I unlock first then flash the ROM or flash the ROM first and then try to get it unlocked?
4. Will flashing the ROM directly unlock the phone itself?
Please advise.
...
you could try gsm zambia to unlock your phone it works i tried it myself a few days ago, also after my phone got unlocked i flash the U firmware/rom and the unlocked remained. so you should unlock your device first then flash the U firmware :good:
PS. if you one nougat better to downgrade if you can do marshmallow so when you wont have any issues flashing to U firmware. :cool

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
Sent from my SM-G935V using Tapatalk
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.
So I've spent a few hours searching XDA to find the right resources on how to flash a different U.S. carrier's GS7 Edge firmware on the T-Mobile branded device. I found out that since all the internal hardware for all U.S. devices are identical, I'd be able to flash any one carrier's firmware on to any carrier's device, provided there are no inconsistencies with the bootloader versions of the firmwares.
The phone is intended for an extended family member and I am able to purchase a T-Mobile GS7 Edge for significantly cheaper than from any other carrier. Because it will be used on AT&T's network, I wanted to make sure I got everything right before I get started. I either want to flash the AT&T version which will allow it to be fully compatible on the network, or the Unlocked version. Apparently, the unlocked version is completely debloated since it's not associated with any carrier and provides better benchmarks, especially battery life, so I'm interested in that.
I've compiled the resources I need in the following:

etc.
One question I have is whether I am able to flash the Unlocked firmware at all. I don't currently have the device in hand so I can't check the baseband version, but my understanding is that the Unlocked version is currently on a lower bootloader version whereas it is v4 for AT&T or T.Mobile. This would mean I would be able unable to flash the Unlocked firmware if the device already has a higher version of the bootloader, right? Conversely, I would be able to do so if the T-Mobile bootloader was on the same version as the Unlocked version (e.g., if the device hasn't had an update to its bootloader).. The same issue would arise if I wanted to go back to a carrier firmware. Where can I find a list of T-Mobile firmwares and their bootloader versions so that I can check? Threads I've searched are saying I can't go to 935U from 935A/T because of mismatching bootloaders but others are saying I can go back to 935A/T on Nougat (same bootloader versions?) so clarification would be greatly appreciated.
Edit: Just discovered the bootloader version can be determined by looking at the 9th character in the baseband version. Pretty simple!
Another question I have is whether flashing the AT&T firmware will give me VoLTE, Wifi Calling, tethering, etc. on AT&T's network. I've established that if I flashed the Unlocked firmware, I'll lose these functions (unless I root the phone, but that's a no-go since I need Samsung Pay intact). Just wanted to make sure that I would retain these features if I flashed the AT&T firmware on the T-Mobile device. Also, would I receive all OTAs pushed from AT&T while I'm on their firmware, even though it was a T-Mobile device? Or would I have to manually update it somehow?
Many thanks in advance.
Yes you can flash the unlocked firmware, I do recommend flashing the at&t CP (radio) though for better signal.
For tmobile all we lose is video calling, we retain everything else. I can't answer your other questions since I have not used this phone from tmobile on at&t. I have used the at&t model on tmobile with U and had no issues.

^^^^^this man is correct. Also, is the device you want to flash Carrier unlocked? Even though youre flashing a different carriers firmware or even the U firmware I believe the IMEI still needs to be unlocked from the original carrier. Obviously just pop the at&t sim card in the t mobile phone to see if its unlocked. hope this helps.

flashing the at&t firmware will just be like having an original at&t s7 edge so yes. The Unlocked firmware will be lighter with no video calling(no carrier apps, no carrier boot animation, some of the quick toggles will be different) you will retain VOLTE HD calling, wifi calling(if at&t has that) and with the at&t you will have all the bloat (about 2-3 GB of used storage plus more a tad bit more use on ram usage) which will use more battery. remember like stated above, if you do decide to flash the U firmware, make sure you flash the latest At&t CP being you will have better coverage since youll be on the at&t network.

2) Will Android Pay Work?

I Flashed an AT&T S7 Edge with T-Mobile firmware and:
1) Status remains unmodified
2) Android pay works (as well as Samsung pay)
3) I've already got 2 T-Mobile pushed firmware updates that installed without any issues.
Don't know if this helps, but I'd think it would be the same going from T-Mobile to AT&T.
I did also have to use a modified version of "ODIN" and flash a "PIT" file because T-Mobile has a different partition than AT&T.

Am I doing everything right?
Should I just flash all U files (including Radio) and flash ATT Radio later?
Please advise
Hi team
I have the tmo ime version of the s7 edge, but flash the ATT firmware BQC2 and now I can not go back to tmobile firmware or the U firmware I got the following error in Odin:

I have a at&t Galaxy S7 active unlocked and i transfer my service to T-Mobile but I am not able to get updates can I flash T-Mobile firmware so I can have the T-Mobile interface and updates. What do I need to do to get the updates.
All US variants can flash the firmware interchangeably. Just download the corresponding firmware and flash everything(Except for the modem if you'd want to keep the original modem). You dont need anything special. If the default odin dont work, then try the comey "cracked" version.

Why is it that we use the CP for AT&T; however, use the Unlocked CP for TMobile? Are the radios the same for the unlocked and T-Mobile variants? Where would I get this information if I needed it in the future?
I have a GS7 edge locked to T-Mobile with the Device Unlock app. Will flashing G9350U firmware unlock my device and bypass the Device Unlock app or will I still need to use this app to unlock?
Radios are different. I flashed ATT Radio after I flashed U firmware. Though honestly I cannot tell the difference

you did the sae thing that I am currently doing. going from tmobile (I believe) to AT&T firmware. I am going from verison (which shouldn't matter) but when I did it the first time odin 3.12.7 gave me a message of success after only one "sector" of the whole thing went green. but the phone rebooted to an error message. did I do something wrong? help??

Sorry not an expert, but I read several times here to use Price COmsy ODIN and I use that one. Please try
OTA Update is not working after changing to U firmware.
I had stock T Mobile last firwmare installed, but I was sick of poor battery and lag
so installed this firmware https://forum.xda-developers.com/tmobile-s7-edge/how-to/6-8-t-mobile-935u-firmware-qe2-t3619151, full wipe.
Now I have worst battery performance. 12% draining overnight (6 hours) without touching the phone at all. It shows a new update but it fails when I OTA update. looks like the update it's being installed but fails at the end. Don't know what's wrong but totally hate battery.
Edit: Android pay is also not working..

I Flashed an AT&T S7 Edge with T-Mobile firmware and:
1) Status remains unmodified
2) Android pay works (as well as Samsung pay)
3) I've already got 2 T-Mobile pushed firmware updates that installed without any issues.
Don't know if this helps, but I'd think it would be the same going from T-Mobile to AT&T.
I did also have to use a modified version of "ODIN" and flash a "PIT" file because T-Mobile has a different partition than AT&T.

What pit file did you flash? Did you flash the the pit file Odin pulls from your phone? Did you flash an att specific pit file?
I got the official Oreo on the u firmware, does anyone else have it and what are your thoughts i.e. Battery and screen on time, it seems a little faster to me.

I just flashed the stock Oreo G935UUEU4CRG2 firmware (Vzw) today. I will run it bone stock for a week and report back. I should be able to tell if there's a significant difference in battery life and performance from the stock V firmware because I've never rooted my S7 edge and have run the stock Verizon firmware since new. With this Oreo U firmware, I do hate how Samsung Pay has that quick launch edge feature at the bottom of the homescreen that can't be removed.
I am very interested in the U version of the firmware . I have the Verizon Galaxy S7 Edge G935V w/ Android 8.0 but use it on Straight Talk with their AT&T sim card.
I had to change it from CDMA to GSM, also had to add a new APN for Straight talk.
It works but the phone is missing LTE bands 12 and 17. Band 17 is used in my area and without it the phone connects
to a different band and its weak in my area.
I am trying to learn if I can put the G935U (AT&T) firmware on the G935V and will I get band 17.
I know band 17 is in my area because of my previous phone of a week ago, Nexus 5.
Would you know if it can be done, and where would I find recent info how to do this
along with what bands and features would be offered or not available.
Thanks,
Ken

On my G935V, flashed with U Nougat firmware I have received the Oreo U upgrade.
It works great, the only issue is that it reverted the LTE bands to the typical V version bands. I had to re-activate the other LTE bands, just because... I can. My provider is still a Verizon MVNO, and VoLTE is working.
What I like about the Oreo is the Bluetooth codecs - besides the aptX and Samsung HD (UHQ) now Google provided native support for LDAC (Sony). I couldn't wait to get that, because I really wanted my Sony's MDR-1ABT headphones to be used in their full glory (LDAC codec).
PS: To appreciate the quality difference you need to listen to FLAC files.

Ken, first check out the supported bands between the Verizon and the AT&T S7 edge in the link below. It will confirm the discrepancy in supported bands between the two models.
https://www.phonemore.com/compare/p...5v-vs-samsung-galaxy-s7-edge-sm-g935a/3296028
Then go to this link and download, extract and Odin flash the AT&T "U" firmware and see if that will open up the AT&T bands for your Verizon S7 edge. It very well might. I think you should also choose the option in Odin to "Clear EFS" before you flash so that it can be rewritten fresh upon bootup with your AT&T sim card. Do this and report back your results. Good luck.
https://updato.com/firmware-archive-select-model?record=0A1AF06A906411E89F15FA163EE8F90B
Thank you for your reply.
I am downloading the firmware G935U (AT&T) firmware now. Its going to take several hours because I am not a member of that download site.
I did he A/B comparison and both phones seem to be identical except for the band coverage. The AT&T has band 12 which from my reading
is 700MHz and it includes the segment band 17 has so if I understand it right if I have band 12 I should be in good shape.
It also seems to have all the bands of the 935V except for band 13. The 935A has actually more bands of coverage.
Could you clear something up for me. Once I do this I am reading I can't go back to the Version S7 Edge G935V.
However would I be able to convert it to one of the other carriers like T-mobile ?
You are the first that stated to check the EFS box.
With ODIN I will be choosing all 4 files but making sure I do NOT choose the HOME file, is that correct?
After flashing are there any other special instructions I need to do or will the phone right after flashing just
need to go through the normal setup along with possible adding the same APN config I am using with it on Straight talk w/ the straight talk AT&T sim?
thank you,
Ken

Yes you can go back to the stock verizon firmware.
There's two csc files in the firmware pack CSC_HOME will not wipe everything and the regular CSC wipes everything. You need to choose the regular CSC so it wipes everything. So backup your internal storage if needed. You may or may not need to manually enter your straight talk APN. Your SIM and APN should be detected upon first boot. Just make sure you choose the regular CSC file and not the CSC_HOME. You want to wipe everything and start fresh. If your APN doesn't automatically populate after flashing the rom then enter it manually. You should have no problems with this version of the U firmware.
G935V to G935U (AT&T)
If its written I have not found it yet but it would be nice to have a before and after as far as what you will gain and what you will loose after the firmware flash. It would cut down
on all the follow up questions, especially for me.
After flashing, you said I can return to stock firmware. Its strange I am reading you cannot return due to a BL that will not be compatible anymore with the Verizon firmware.
The G935V has been taking updates when it was on Verizon. Will this continue after changing it from a G935V (Verizon) to a G935U (AT&T) while on Straight Talk with their AT&T sim?
Does this G935U (AT&T) flash change any specific characteristics of the phone like its serial number and model #? I ask because the Samsung Smart Switch program besides
backing up your phone can also return it to stock (in case something corrupts it) and I am wondering if I give it the current serial# and model number G935V, will there be any problems since its model number firmware will be different.
I was advised when using ODIN under "Options" to check "Phone EFS Clear" . Does this still sound right. All other settings should stay as is.
Thank you,
Ken

Q: After flashing, you said I can return to stock firmware. Its strange I am reading you cannot return due to a BL that will not be compatible anymore with the Verizon firmware.
A: When you flash a different U.S. firmware it has a bootloader included in the firmware. They can be flashed between the different U.S. firmware with no issue. the only time you may not be able to flash a firmware and bootloader is when you attempt to "downgrade your firmware to an earlier version.
Q: The G935V has been taking updates when it was on Verizon. Will this continue after changing it from a G935V (Verizon) to a G935U (AT&T) while on Straight Talk with their AT&T sim?
A: Yes, but the updates may not come as often as the carrier version of the firmwares such as Verizon, sprint, T-Mobile or AT&T. But you will get updates. It seems the carrier firmware will bring more frequent security patch updates than the "U" firmware.
Q: Does this G935U (AT&T) flash change any specific characteristics of the phone like its serial number and model #? I ask because the Samsung Smart Switch program besides
backing up your phone can also return it to stock (in case something corrupts it) and I am wondering if I give it the current serial# and model number G935V, will there be any problems since its model number firmware will be different.
A: No. The model#, IMEI, etc will not be affected. Only the software version will be affected as well as carrier specific update compatibility will be lost due to the "U" firmware.
Q: I was advised when using ODIN under "Options" to check "Phone EFS Clear" . Does this still sound right. All other settings should stay as is.
A: Yes. If you are having issues with network configs, you can choose to wipe efs so that it will rebuild upon first boot of the new firmware. This is only recommended if you have issues connecting to the network. Otherwise don't do it.
Since I'm on a roll I have another quesiton,
I dd a side by side comparison on this site
https://www.phonemore.com/compare/p...5u-vs-samsung-galaxy-s7-edge-sm-g935a/5532054
The phone called G935U has several more bands than the 935A (AT&T). Would this be a different G935U flash as compared
to the G935U (AT&T) ? If so would that not be the firmware to go with? It covers CDMA as well as GSM with the extra GSM bands.
This would be very similar to my G935V which offers CDMA and GSM.
Do I have it right NO CDMA capabilities on the G935U (AT&T) firmware?
Thank you for your replies its been very helpful. Its been a mystery trying to find out
what features you end up with with G935U and if their is a non provider version like in the above link.
Thank you

G935U Product Code USC vs. G935U (AT&T
Last night I flashed my G935U. It took 3 tries with the 3rd working after switching to a different ODIN reversion.
The phone works fine, no issues except I am disappointed I lost all the CDMA capabilities should I want to try straight talk with a Verizon sim.
After I flashed the file from the updato.com site I searched and found another G935U with Product Code USC. USA
https://updato.com/firmware-archive-select-model?record=05B44581906411E89F15FA163EE8F90B
A little more research and I found this is the unbranded version (correct me if I am wrong) The unbranded version appears
to retain CDMA plus have more GSM bands than the G935U (AT&T)
Could anyone offer some details on this firmware and could I have flashed this instead of the G935U (AT&T) to have retained
the CDMA and get more GSM bands.
Thanks, Ken

In my experience flashing another version will not add the bands. My case - I have flashed the "U" version on my "V" branded S7 Edge and the bands remained for Verizon. The modem firmware will read something that is flashed in the modem hardware and activate only those bands. There is a way to force other bands (see below).
More so, having the "U" Nougat, with modded LTE bands, I got the "U" Oreo upgrade from Samsung. After the upgrade to the "U" Oreo, the LTE bands reverted to the "V" ones (I had to re-enable them again).
I did "force" in the NV the new bands on my V using QPST and QXD professional Qualcomm tools, but since I don't really have a T-Mobile SIM I can't verify if the change works or it is something hardware (like RF amps) that is really missing.
How to: https://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
The stock value for the "V" hardware, in the NV cell #6828 is 4190. That corresponds to LTE bands 2,3,4,5,7,13 (check with the LTE calculator).
I have changed the value to 2062440470751 that corresponds to bands 1,2,3,4,5,7,8,12,13,20,25,26,29,30,38,39,40,41 (close to what U would have natively). Again, I couldn't test if the software change is sufficient for them to actually work, but I have a feeling it does not.
When I traveled recently to EU, I have used cellmapper to check the LTE bands. I never saw B20, even if, on the map of that country, B20 was available in that rural location. I had only 3G.
G935U vs G935U
I posted the wrong link
This is the one I have my question on
https://www.phonemore.com/compare/p...5u-vs-samsung-galaxy-s7-edge-sm-g935a/5532054
This compares a G935U vs. a G935A
To get to the chase, what firmware would I flash to get the features of the G935U (left picture)
I just flashed my phone with the G935U (AT&T) and although it works fine with no AT&T bloatware it is missing
some of the GSM bands of the G935U (Left picture) and all of the CDMA bands.
Thank you,
Ken
Like I said above, the different firmware does NOT change the LTE bands.

G935U with Product Code USC is the "U.S. Cellular" network. I believe the way it works is the software will use the installed SIM to configure the network compatibility mode that will be available in network settings. The true "U" model of the S7 edge will have hard coded support for whichever bands samsung determines for that model number. The different versions of the "U" firmware are specific for whichever carrier/network the phone will be used on. I'm not sure which firmware would allow both GSM and CDMA networks to function simultaneously, but there is an app in google Play store called "network mode" and you could give it a try and see if it will open up simultaneous GSM/CDMA support in your network settings. I do know that Sprint's firmware does have GSM and CDMA support and I'm familiar with that because I have had sprint for nearly 10 years and have a lot of experience with the samsung software as I've built several ROM's including port ROM's over the past few years. Try the Sprint "XAS" firmware. That's the global version.
Hey Everybody,
So I've come to realize that my unlocked US S10+ on AT&T didn't have VOLTE or Wifi calling as options in the communication/call settings menus. this is pretty disappointing as it seems that using the unlocked phone with Verizon you get these features, and they make a decent impact on my use of the phone.
My understanding is if I flash the ATT firmware to the phone I would get the functions, so being an amateur I followed some simple guides to SamFirm AND ODIN, and downloaded the ATT CSC firmware for my model number. However after going through the Odin process and resetting my phone it is still showing the same Software information as prior to my installation, and I do not have the features.
I saw a thread on the board stating that the ATT firmware isn't available yet, so I'm not sure if what I downloaded was actually any different than what is on my phone,and my phones "Service Provider Software Version" did already have ATT in the description, which is a bit confusing to me.
Am I correct in understanding the only way to get the features would be through a firmware flash? And would anyone know if I had flashed the right firmware, and what the original firmware CSC would be for my model if I needed to revert?
My information is:

If it's anything like the S9 was, you can't just ODIN the firmware/CSC. You'll just get the bloat with none of the features you want.

I've heard this as well. If you want those features on a Samsung phone, it has to be at&t branded. I ordered an at&t phone from Samsung since I make good use of wifi calling. It works fine on my unlocked P3XL but no dice on the Samsungs.
I have the same phone and service and when I went to update my imei they told me it could not find the phone. So I was without lte/4g for a day until I gave them a imei to a s8 active. Now I have data at least

I noticed the service provider software version to be : SOAMC_SM-G975U1_OYM_ATT_PP_0033( thirty three at end),
so anyway to update the service provider version? does that come from the SIM ??
I have an unlocked S10 plus and I flashed the AT&T Firmware. I now have VoLTE and WiFi calling unlocked on my phone using AT&T. You need to make sure you flash the U version of the firmware, not the U1 one. Unlocked S10 is using the U1 firmware already so flashing that one again changes nothing.

I kinda doubt it but did any of you with unlocked phones that flashed the AT&T firmware get any better service? I've been considering it to get VOLTE but just wondered

At first like you I downloaded the wrong version and nothing changed. I finally flashed G975USQU1ASBA and now have VOLTE/WIFI Calling and of course all of the bloat. But at least those two functions are working. Make sure that you complete a clean flash when I did a dirty flash I had problems sticking on the loading screen.
I believe you just need to call in ATT to take care those carrier specific features .
Which firmware can I flash with Odin to my S10+ Xfinity Mobile unlocked to get AT&T OTA updates? Currently have ASF7 flashed from the latest unknown firmware uploaded to Sammobile. I flashed w/o USERDATA. I just want to be able to get future OTA updates as I just switched my carrier from Metro by T-Mobile to AT&T. I was using U1 US unlocked firmwares on my Note9 & S10+ but want to use carrier perks now with AT&T.
What's with AT&T being the only ones to not release update files? You would think they all would be required to release them. More AT&T customers need kick up a fuss about it.
