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.

Hey everyone I use an ATT I717 unlocked on T-Mobile but it is on 2.3.6... Is there a flasdhable zip to bring my phone on a T-Mobile stock rom that is current? Also if there is will it contain the T-Mobile modem if it is necessary. Using the ATT phone I get normally LTE signal in most places. Thanks
Hello XDA!
I'd like to buy a Note 5 to use on AT&T but I'd like to have all carrier logos and bloatware removed without rooting. I found that the N920C has no carrier branding or any applications, however it has some LTE issues on AT&T.
I know this post is under the Note 5 but here's what I experienced with an S7.
I wanted to acheive the same goal on my S7 by flashing the unlocked firmware, and it worked. I installed G930U firmware on a G930A by flashing CP & BL from the A firmware and AP & CSC from U, given that they both are on the same version. (I downloaded the G930U firmware off Sammobile which said G930U AT&T, so I'm assuming it contains the AT&T modem and bootloader, since it mentions AP and CSC to be G930U). I've been using it since, and I get LTE just fine, even LTE+, though I lost a few carrier features like VoLTE and WiFi calling.
I read that the reason why this worked is because the hardware is identical across all S7s, and that the software is what enables certain radio bands. Is this true? I've always had the notion that different carriers have different hardware. I also read that the bootloader is locked. Would that be a concern while flashing official firmware? It's worked for me so I'm a bit confused.
Anyways, my main question is: will this work on a Note 5? Is it possible to buy an N920A and flash N920C AP & CSC with CP & BL from the ATT firmware? Will the modem inside the N920A designed for the AT&T frequencies be enabled while under the N920C + ATT modem & bootloader hybrid?
On the subject of hardware, if all Note 5s are the same internally, could I do this to any other carrier phone like a N920P instead of an N920A?
Apologies for the wall of text. I wanted to provide as much information as I can.
Update
I ended up buying an N920i as other users here have reported compatibility with AT&T.
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.

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.
Verizon is my carrier and I am upgrading to an S10 from an S7. I bought a new S10 loaded with the first Verizon version of Android 10, G973USQS2CSL1. I want to get rid of the bloatware and go back to Android 9. My plan is to flash the U1 firmware, G973U1UES2BSIV, using all 4 of the U1 files. Then flash the Verizon CSC file from this firmware, G973USQS2BSIV, so I can get the "Advanced Calling" for Verizon. I was going to try to do that on my S7 but never got around to it. Here's a thread I created on the S7 forum that said that's what I would need to do to run the unbranded firmware on the S7 but also have Verizon's Advanced Calling (wifi calling, video call, hd calling). https://forum.xda-developers.com/galaxy-s7/help/install-verizon-advanced-calling-g930u-t3997525
I noticed the S10 Verizon firmware now has a 5th file, a USERDATA file. Will I need to also flash that?
I wanted to point out, my new phone is currently locked, but Verizon automatically unlocks it after 60 days. https://www.verizon.com/about/consumer-safety/device-unlocking-policy Will it be a problem if I flash the unbranded firmware on a phone that is still locked? Since Verizon is my carrier, I will obviously be using a Verizon SIM card.
Thank for the help.
You can flash any firmware to your phone as long as it's for the U or U1 models as the "U" means Universal. Bought a phone from AT&T? Flash the Sprint or T-mobile firmware without issues. Same for Verizon and other U.S. carriers firmware.
Flashing the unbranded firmware will get rid of the bloatware, but will also get rid of other features like wifi calling, advanced calling, etc. The user data file is just all of Verizon's bloatware and info crap.
As for going back to Android 9, you can do that as long as you're still on the v2 bootloader. If you've upgraded to the v3 bootloader via OTA, you won't be able to return to Android 9.

I'm on v2 bootloader. Have you heard of flashing the VZW CSC file on top of the U1 unbranded firmware? Apparently people have done it on older devices, like the S7, that only took the 4 files when flashing. I'm trying to run unbranded firmware but still have the Verizon Advanced Calling (wifi calling, HD calling, video call).
Okay if you're on bootloader v2 then you can go back to Android 9. I haven't heard of flashing the carrier CSC file with the unbranded U1 firmware. It might work or might also brick your phone.
