AT&T Software Update OTA

I'm using an AT&T Note 3 for T-Mobile. I believe when 4.4 first came out I did not want to update so I froze the AT&T Software Update, however I now want to update OTA from 4.3 to 4.4.4. How do I re-enable the software update OTA? I tried doing a factory reset thinking it would recover it however it didn't. Whenever I go to Settings>General>About Device and tap Software Update nothing happens. I also tried using Samsung Kies 3 to update however it says I'm not the latest firmware, 4.3. Which I believe is not???
Any help is appreciated to update from 4.3 to latest android.
Thank you!
Found the answer to my question.
Use Odin.

If you are rooted right now you will not be able to get ota updates. The only way to update is to go through odin and update or flash a rom with the newest update or unroot your device and then update.
I'd like to answer your second question but I would like some clarification on the question.
And the update to 6.0 could be from a couple of weeks to a couple of months or even longer. It depends on you carrier and samsung of course.
The phone is the international variant 920c dual sim
I have not rooted yet but will love to do it.
If marshmalow is near them i will wait
No rooted phones of Samsung will receive OTA updates. Unroot by flashing the stock rom with ODIN and look for OTA. Or else, download latest stock firmware from samobile or similar websites and update with ODIN. Then re-root if you want.

Galaxy S5 Active AT&T (SM-G870A) Software Update Help?!

Hello guys;
First of all, Let me post my phone software info:
Android Version: 4.4.2
Build Number: KOT49H.G870AUCU1ANG3
Phone Location: out USA
I tried all methods available to update my phone at least lollipop not even Marshmallow! and every time i get the message "The is the latest software update available to your phone"!
I tried the software update inside settings, Kies 3 (also emergency recovery method), Smart Switch, AT&T SIM Card inserted with USA VPN...etc)...non of them worked for me!
Does any one manage to have a legit Lollipop or Marshmallow Odin Stock Flash?!
I saw some methods over recovery with OTA update packages but it is too risky since there is no Stock ROM for the device in Sammobile also i am afraid to brick the device or losing IMEI and no service Box is supporting it!
looking for your help!?

Thats becuz there isnt for att yet. Therr are over the airs for 5.0 but nothing else. And the update to 5.1 but its stock and unrooted you have to be rooted im sure for that and using flashfire for it so it just changes rom and not bootloader . Allowing you to still downgrade back.

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?

T-719Y Downgrade from Nougat to Marshmallow

I just bought a T-719Y off eBay, and it comes with Nougat installed out of the box despite the description saying it is Marshmallow.
I have tried simply downgrading the device with Odin using a .md5 for my specific device. However, the Tab shows an error saying
[aboot]Fused 3 > Binary 1
Click to expand...
Click to collapse
I assume this is because the bootloader for Nougat is newer than Marshmallow.
Is there anyway to downgrade the bootloader itself? Or am I mistaken about this assumption? Searches on downgrading this device seem to imply that flashing the file with ODIN is enough. Is an unlocked bootloader necessary for a downgrade?
Thanks for the help!
