I was wondering if anyone knows if we can flash stock T-Mobile onto the AT&T G925A? Main reason I am trying to figure this out is for WIFI calling.
Maybe if its possible to odin the tmobile stock rom and the odin the at&t kernel?
WiFi calling only works on tmobile branded phones far as I know
thanks for the commenting..
Hello,
Can someone please post the complete Nougat Firmware. It will be 4 separate files the actual rom file, the modem file, the boot file and lastly the csc file.
I would like to switch my unlocked Sprint Galaxy S6 to Tmobile firmware but in order to do so I need these 4 files to flash via odin. I have done this on my unlocked Sprint S7 so I am confident it will work but need all 4 files.

Official nougat for T-Mobile isn't even out yet for the S6. For now, G920T models are getting nougat via custom ROMs such as LineageOS or AOKP
Thanks I guess I need to ask for newest marshmallow files then.
Hi I'm trying to flash the T-Mobile firmware from sammobile.com, but whenever I try, I get an error at 32% when it says Installing System Update. I attempted to flash CSC,AP,BL, and CP with it saying PASS in Odin. I really need the T-Mobile firmware and am wondering if it is possible to do? I determined that I cant install CSC files and get the error when I try. Any Solutions?
SM-G950U
Odin 3.12.3
T-Mobile Firmware:
PDA: G950USQU1AQD9
CSC: G950UOYN1AQD9
I'm having the same problem with an ATT phone flash with the US "U" unlocked version firmware. When I don't flash the csc it will start up only with the USB plug in but shut down after the beginning startup
Search for a "modified Odin". It was what I used to be able to flash unlocked firmware on a 7 and 7 edge a few months ago. The "normal" Odin wouldn't let me do it, but the modified one did. Though you may need to wait until it's been updated....I haven't checked it in awhile.
Still no solution to avoid the error to 32%?
Try this Odin. This is the one I used to flash the Canadian firmware on mine.
I managed with odin version 3.12.5! But only with BL AP and CP!
When I add CSC I get the error at 32%!
So a priori everything works, I no longer have the Verizon overlay (nor the logo at startup) more by cons I have duplicates in the settings menu ...
What is the CSC file?

The Canadian firmware you got it or? On sammobile I find it not:
https://www.sammobile.com/firmwares/galaxy-s8/SM-G950U/
The Canadian firmware is stock or operator?
I would have access to all the bands?
Its the firmware with the "w" at the end. Please read this thread for all the information on doing this and make sure you want to do it.

so to do this we actually have to go to the canadian firmware first, do the csc change then flash the Tmo firmware? You can't just flash the Tmo Firmware via the modded Odin? Just to save confusion.
I would imagine it's worth it just to get the proper network options, VOLTE, WiFi calling and such.

This is the exact thread that I used. Follow the steps and you can skip engboot. If you flash the full Canadian firmware, its impossible to reverse. So, only flash whatever is in the steps. I successfully went from Verizon To T-Mobile and then back to Verizon. https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487
This tread also helps, who wants to flash their phones: https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817
I started with a Verizon Note 9 that I put the above Unlocked Firmware onto, now that I'm putting the device onto AT&T's network, I'd like to take advantage of the special features that AT&T offers. What files would I need to go about flashing the AT&T Firmware onto the device? I feel pretty comfortable with Odin, I just need help finding the correct files to use with the new boot loader. I can't find them for the life of me. Any help would be very much appreciated. Thanks!

Did you ever get this answered?
My guess is that it's possible that you'll need to flash the U (not U1) carrier firmware to get ATT features to work??
Hi all, I just got a SM-G973U1 (unlocked snapdragon) to replace my old S7 international version that doesn't have working VoLTE. AT&T is shutting down 3G in February, so I need to set up this new phone so that it works in LTE only mode.
I'd like to use TWRP recovery and Magisk root, but I doubt any ported ROMs will work because of Samsung's proprietary drivers for VoLTE/HD voice. What's the best stock-based ROM available for this device? Alternatively, where can I find detailed instructions for installing these items myself and removing Knox and other safeguards from the existing stock firmware (possibly using adb shell)?
If necessary, I'm willing to use the ATT CSC code on this phone. This is not the current CSC on this device.
I'm returning the phone because I haven't found a way to unlock the bootloader.
