I have a Verizon branded note 3 that I am now using on Tmobile. It works fine but it still has verizons firmware and I want to get rid of it... so either Tmobiles firmware or an unbranded one. Ideally an unbranded one.
Please direct me to the correct thread with directions. I am a noob and I don't know exactly what I am doing.
Regardless of whether the bootloader is or is not locked, you cannot flash stock Tmobile firmware on the Verizon phone.
If the bootloader is unlocked, you may be able to flash a custom rom based on the stock T-Mobile firmware.
There is no unbranded firmware for the Verizon note 3 as that model is exlusive to Verizon.

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.
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:

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:

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

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.

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?

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 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.

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.
Hello! I've been out of the Android scene for a few years so I have a question that I can't seem to find the answer to by searches.
Can I flash the unlocked U1 firmware to a Verizon S10+ and use it on AT&T? I know I'll lose VoLTE and WiFi calling, but I don't really care about those. Mainly, I'm just trying to see if I can use a Verizon S10+ on AT&T. Ideally, I'd like to flash the AT&T firmware on the device but from what I've gathered, that firmware isn't available yet.
I had a Galaxy S8+ when it came out and I used Odin to flash between U1 and AT&T firmware so the process isn't entirely new to me.
A bit of background:
I'm looking to jump off of the dead iPhone train and hop back into Android with the S10+. I'm currently trying to sell/trade my iPhone XS Max in order to make the switch.
I have someone who is willing to trade me their Black S10+ for my iPhone as an even trade but their S10+ is from Verizon. It's unlocked but it's still running the stock Verizon firmware.
I just want to know what I have to do with this trade in order for it to work for me. I want to make sure I get a phone I can use. Any advice or input would be greatly appreciated!
Thanks for any help!
I'm not entirely sure if this will work on the S10+, I haven't tried it yet, but when I had the S8+(it was from Verizon as well), I'd take it internationally with a different sim card, it would just prompt me to reboot the phone and it would automatically apply the appropriate CSC settings. I was on stock VZW firmware as well and VoLTE worked (wifi calling didnt).
You should be fine either way though, people have successfully flashed the U1 firmware on their VZW devices for the S10+, so you shouldn't have any issues getting your AT&T sim card to work on it.
Edit: link to get the U1 firmware

I wish Samsung included the BYOD update in the S10+, that would make it so much easier. I think I'm just gonna make the trade.
I've read through that thread and that's what I think I'm going to do. I'd much rather flash the AT&T version, but seeing as how it's not available, the U1 will do fine until it's released. I'll just need to switch to a different voicemail service in the meantime. lol
I got a Verizon S10+ and it is running build PPR1.180610.011.G975USQS2ASGB, I have confirmed that putting an AT&T SIM gives me network ability to call and what not. I want to flash the stock U1 branded firmware, is it okay if I flash G975U1UEU1ASD8 with Odin?

Hello! I've been out of the Android scene for a few years so I have a question that I can't seem to find the answer to by searches.
Can I flash the unlocked U1 firmware to a Verizon S10+ and use it on AT&T? I know I'll lose VoLTE and WiFi calling, but I don't really care about those. Mainly, I'm just trying to see if I can use a Verizon S10+ on AT&T. Ideally, I'd like to flash the AT&T firmware on the device but from what I've gathered, that firmware isn't available yet.

HEY I know have the same problem... Does it work.., I have installed the firmware and all so should I go for it.., waiting for your reply
I have Verizon unlocked phone and I'm able to use internationally where there is no Verizon, but I'm not getting updates so I have downloaded latest firmware should I flash it, also now I don't need any Verizon sim after flashing right ?
Yes you can flash U1 firmware to a U device and vica versa. The U means Universal, so you can flash AT&T, Verizon, T-mobile, or unlocked firmware to it. You gotta use the patched version of Odin though.

As Just changing csc without installing the system is more than enough. Even the company logo changes. Just look for the samkey program and you will see
