I need some help. I have a Verizon S8. I flashed the unlocked firmware and am running the phone on T-Mobile. The problem is, I cannot seem to flash the phone back to the Verizon Firmware. It's also not acting like an unlocked phone, but rather a T-Mobile phone (complete with T-Mobile splash screens, even though I never flashed the T-Mobile firmware). No matter how many times I flash the Verizon Firmware using Odin, the phone still boots up as a T-Mobile phone. Any ideas?
I flashed my Verizon s8 with the files from this page, everything works flawlessly, no bloat.

Hi all,
I bought the Galaxy S6 from AT&T when it came out, but switched over to T-Mobile from AT&T last year. Because of this, I have been unable to get any updates and have been stuck on Android 6.0 when the current release is android 7.0, so I've been thinking of flashing my phone. I was curious as to whether I'm able to flash my G920A with Tmobile's G920T rom? Would it work? And if so, after I flash it, would I be able to receive updates normally from T-mobile's servers, as I'm currently using a T-mobile sim, or would I have to flash every subsequent update?
Thanks
Doubtful, since AT&T has a locked bootloader. If the bootloader was unlocked you might be able to try.

You cannot flash a G920T firmware on a G920A. First off, Odin won't let you because the G920T firmware is only signed to be flashed on the G920T.
And even if you somehow rooted and used FlashFire to force the firmware onto your device, the firmware would brick the device, and without a USB jig or SD card port, the brick would be permanent.

I too am seeking answers on this as I have an SM-920A I brought over to t-mobile. Unlocked the phone, installed the t-mobile SIM and the phone works fine, except, it still has all the old ATT apps I no longer need or desire to be there AND without the T-Mobile apps installed, I cannot use their LTE Signal Booster. Is there any way I can install these t-mobile apps that would have come with the SM-920T load?

Just do this and remove the AT&T apps you don't want completely.

So, what can be done -- if anything--to solve this issue?

I originally bought and used this phone on AT&T. I have since moved to Mint Mobile which runs on the T-Mobile network. Some features (like wifi calling) would be availible if I had a T-Mobile rom instead of an AT&T rom.
Is there any physical difference in the Phones (baseband, kernel etc.) that would preclude me from using Odin to flash an official G920T rom on my phone?
You can see from my signature I haven't been here for a while .. lol
Thanks in advance

G920A has Band 30 antennas, while G920T does not. Locked bootloader on G920A will prevent you from flashing G920T firmware. It's not like the S7 where the hardware is identical and software locked.
You can do the reverse, though: flash G920A firmware over G920T as unsigned firmware. But you still won't get Band 30 as it is physically not present.
Hello,
I have some noob questions to ask before trying this out on my G920T (Baseband version: G920TUVS6FRC1 - which is running Android 7.0). Here's a little bit of background about my situation, I was with Tmobile Prepaid up until the end of December 2019. I ended up getting my phone unlocked by Tmobile and transferred my number to an AT&T Prepaid account.
I was looking to try and get HD Voice/wifi calling working on my unlocked G920T. My question is, when flashing different carrier firmwares, does it matter what the storage capacity of the phone is? Would I be able to flash G920A firmware (no matter if it came from a 32GB Samsung S6, or 128GB (not sure if AT&T ever had a 128GB version of this phone)?
Also I read that it is better to use the princecomsy (my apologies if I messed up on the name) version of Odin rather than the non-cracked versions. Is that correct?
Would I be able to flash different carrier firmwares regardless if my bootloader is locked?
Thank you to anyone that can help.
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.
