Flashing stock firmware

I want to get rid of the AT&T updating process and their branding on the phone entirely. I am running MJ5 4.3 JB, and from what I was able to do with my S4, I can flash an international version without the branding. Is this correct with the note 3?

[I Need] S6 AT&T Stock recovery 5.1

As it's mentioned in the title i need an AT&T stock recovery for my phone ( G920F it's written on the back ) (and G920V on the download mode) but im blocked with a blue screen which says "System Software not authorized by AT&T" so i need to get back the stock recovery
G920F is not the AT&T variant. G920A is the AT&T variant. G920F is a factory unlocked phone. Look in this forum for your phone.

"secure check fail = bootloader" when flashing metropcs firmware on sprint galaxy s6

"secure check fail = bootloader" when flashing metropcs firmware on sprint galaxy s6
I have a Galaxy S6 that was on Sprint. I had Spring unlock it. I am trying to get it flashed to work on T-Mobile or MetroPCS.
I have downloaded Odin 3.12.5 and the latest factory Android 7.0 firmware for T-Mobile G920T and the variable for MetroPCS G920T1 .
I load Odin and click AP and load the firmware. I put my phone in download mode. It shows FRP off and Secure download enabled. I then hit start in Odin. Checksum passes but Odin fails after seconds. When I look at the phone's screen it shows the error "secure check fail = bootloader" .
I have read and read and watched videos, but cannot get past this error unless I flash a Sprint firmware to the phone.
What is weird is I had no problem whatsoever doing the same T-Mobile firmware flash to my Sprint Galaxy S7.
I prefer to flash it with T-Mobile's G920T1 version. But at this point I just want to get it flashed to be used on the T-Mobile network.
Is there a way to fix this error or can I flash the firmware in recovery on the S6? I read something about it but wanted some more confirmation.
Thanks in Advance

Downgrade current binary of my SM-G920T

II have a Samsung Galaxy S6 with carrier T-Mobile (SM-G920T) that was flashed with stock ROM G920TUVS6FRC1with android 7.0 but the security does not work, I tried to flash it with G920TUVU1AOCG_G920TTMB1AOCG_TMB with Android 5.0.2 through Odin but I have sw check fail device: 6 current: 1. So I used ASSAYYED_KITCHEN_V1.82_STABLE and create a zip with system.img and boot.img of the second ROM and flashed it with TWRP. Everything seemed to go well, the only thing that left was carrier unlock that I did it with Octopus Box but when I insert my sim the mobile go into upload mode. I need to flash it with 920TUVU1AOCG_G920TTMB1AOCG_TMB or, if exist, with any other ROM with Android 5.0.2 but for that seems that I need bypass bootloader check. Any suggestion?
