SM-935V

I would like to know if it's possible to flash the firmware for
T-mobile I'm looking to leave verizon I know that the Verizon variant does not have 2 of the lte bands that T-mobile uses can I use Odin to Flash the 935t firmware to get the band's or am I asking something that is not possible. Thanks in advance

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?.

Want to Flash AT&T or Unlocked Firmware on T-Mobile Device - A Few Questions

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:
https://forum.xda-developers.com/att-s7-edge/how-to/firmware-att-s7-edge-g935a-official-t3412312

http://updato.com/firmware-archive-select-model?q=SM-G935U&order=date&dir=desc&exact=1
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.

Yes, it'll be unlocked, so there won't be problems there. If I flash the AT&T firmware and not the Unlocked firmware, I will retain video calling, yes?

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.

I was able to flash back to T mobile from the U, I never tried anything with a At&t variant or the at&t firmware

I am also interested. If I flash
1) Will the device status remain "Unmodified" - I use Good for Enterprise for work email and it won't function on rooted or modified devices
2) Will Android Pay Work?
3) Will I get Software updates directly?

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.

Thanks! I am almost ready. Final checks
- I downloaded 935U firmware from here https://forum.xda-developers.com/tmobile-s7-edge/how-to/4-28-t-mobile-935-firmware-t3597866 (File is G935UUEU4BQD2_G935UOYM4BQD2_TMB.zip)
- I am planning to use ODIN 3.12.7
- Since I am on ATT Network I will use ATT Radio (CP File). I downloaded ATT firmware from here => https://forum.xda-developers.com/att-s7-edge/how-to/odin-files-to-s4bqc2-g935a-t3582874
I will use this CP => CP_G935AUCS4BQC2_CL10280464_QB12904088_REV02_user_low_ship_MULTI_CERT.tar
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:
Error device info
Who can help me,?I going to gift my s7 edge to my brother and he is on Tmobile network

Galaxy S7 active
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??

OTA Update is not working after changing to U firmware.

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..

AT&T Galaxy S7 Edge (G935A) on Sprint?

I got a brand new AT&T S7 Edge (G935A) and requested the unlock code to AT&T. I have a few questions I was hoping someone could answer:
1- Once unlocked, would it work on Sprint?
2- If it would work, would I face any constraints such as no LTE, higher than normal battery consumption, loss of features, etc.?
3- If it would nor work, would it work if I flashed the Sprint stock ROM and in this case, what is the most current and where to find it?
4- Any suggestions or advice?
Thank you all in advance.

I just came back from sprint and they couldn't make my phone work, systems says it's not supported.
Same thing as yours, G935A unlocked using unlock code provided by At&t as the phone was paid in full.
Not sure what to do now?!

Have you tried calling/chatting with Sprint & providing your 935A's IMEI number to try to add your phone into Sprint's network? Also, where did you get the Sprint SIM card from? AFAIK, the SIM card has to be a newer type in order to support newer Sprint phones.

I am in the same boat. I went to sprint and ask them to add G935A's IMEI number into their network and it's system is not taking . Any suggestions.

Sprint uses CDMA, AT&T phones doesn't have cdma, that's why doesn't work

Based on the specs of the Spring Galaxy S7 Edge, Sprint seems to operate both on CDMA and GSM. See here
So, the question is: installing a carrier neutral ROM (from the G935U) on an unlocked G935A and configuring the APN to Sprint's specifications (see below), wouldn't it work?
Name: APN2 LTE Internet
APN: n.ispsn
MMSC: http://mms.sprintpcs.com
Multimedia message proxy: 68.28.31.7
Multimedia message port: 80
MCC: 310
MNC: 000 // Do Not CHANGE!
APN type: default,supl,mms,dun,fota
APN Protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
Bearer: LTE

But why Sprint is not taking IMEI into their system?

In the same boat. Bought the SM-G935A outright. Got it sim-unlocked by AT&T. Flashed it with the SM-G935U rom. Sprint won't activate it because it's not in their system. None of the reps seem to know how to add it to their system. Makes no sense. ALL S7's sold in the US have the exact same hardware. This phone should work with Sprint without any issue. The SM-G935U firmware has support for all Sprint bands.
This appears to be all on Sprint's side. Their janky provisioning system won't add new devices.

Did any of you guys ever manage to connect to sprint using the at&t s7 edge??? I've been trying and have had no luck. I even got an SIM unlock key to work and nothing.

It won't work. Sprint doesn't let you change phones by simply changing sim cards. You have to add it to the sprint database and it won't accept the at&t number.

When You get into Recovery mode what do you see? What is the ROM version displayed? For example for Sprint you will see PU5QJ3 or PU5QK1 at the end of the name/version for the latest ROM and my guess you are seeing it has a 4. If you try overwriting with a 4 from a 5 then it will fail no matter what. I think it's an update to the chipset in the phone itself. A firmware update. Coming from ATT maybe try downloading the last version with PU4 in the name/version. Then take it to the store and have them convert it.

Have you tried using odin with a pit file? It worked with b3 and b4. Haven't tried it between b4 and b5

Can a G935A work on sprint? I think it is a GSM only phone. Sprint uses CDMA. I know the G935U has both CDMA and GSM and will work for most carriers in the US. If sprint had GSM, I would buy a oneplus in a heartbeat lol

Yeah from what ivevread over the last few wweeks, it seems that it has the proper radios for sprint cdma, but sprint themselves wouldn't add the phone to their system.

It looks like a lot of people are having the same issues on the sprint forum as well. from what I saw the reps are getting a lock error when adding the unlocked at&t phones. I am not sure if maybe at&t has them locked somewhere, sprint's database sucks, or something else. Sprint techs tend to give up pretty quickly when it comes to unlocked phones. Have you tried going to your sprint account and activating the phone on the site your self?
If all else fails, I would try to see if you can switch it out with a factory unlock version. If you bought the phone less than a year ago, you maybe able to persuade Samsung to swap it out since it has a one year warranty with them.
UPDATE: Looking at the sprint site, the special edition s7 and s7 edge are the only compatible unlocked phones for sprint. Since it does not state the at&t version sprint will give you issues trying to port that phone over.

Thanks I went ahead and scrapped my s7. Battery was having issues and was lagging to much.

at&t to verizon

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
Sent from my SAMSUNG-SM-G935A using XDA-Developers Legacy app

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.

G935T to G935A

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?

unlocked us s8 to tmobile.

I've been searching and can't find a definitive way of flashing TMobile firmware to the unlocked s8.

I assume you have US Unlocked S8....
Normally you don't need to flash it with T-Mobile firmware because most of features are supported such as: VoLTE, Band 12 and WiFi Calling. If you do decide to flash here is the tread: https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817

Yes US unlocked. The TMobile radios are better and utilize the new tech that TMobile uses. I'm assuming I can use just the radios, but there aren't any definite answers.

I am trying to get figure out the same answer.
I also have the G950U1 and would like to flash the T-Mobile firmware to obtain the 256qam and 4x4 radio.
I'm still searching for an answer.

There is also T-Mobile firmware that doesn't have bloatware, but I don't know if it is missing any feature that you guys are looking for. I do have an unlocked S8, but haven't flashed it yet.

I've attempted using both Odin, and the modified PriceComsy Odin to flash the T-Mobile G950u firmware onto the Unlocked G950U1, and it results in FAIL! (DeviceInfo).

Ended up just flashing the modem. Just need to see how this thing works now

In case anyone wanted to know how the T-Mobile modems work on the unlocked variant, I'd say quite well with all TMobile features working

But what kind of speeds did you have before that?

I am going to go off the limb and suggest that flashing the 950u T-Mobile Firmware doesn't give us the 4x4 MiMo Radio and 256QAM. I've not seen a difference in call quality, data speed, or signal strength. Can anyone let the community know what the three TMB/TMB/XAA mean?
This should be a big decision differentiator when selecting between the S8 unlocked and S8 T-Mobile branded device on the T-Mobile network.

The fastest speed that is in the screen shot, half of that. Also I've noticed I don't get random lte to H drops anymore where I normally would in weak TMobile areas.
