Help Downgrade G920A Nougat 7.0 (G920AUCU6EQCF) - AT&T Samsung Galaxy S6

Friends, colleagues and colleagues.
I hope you can help me in the next problem. I have a Samsung Galaxy S6 Flat G920A from AT & T. I updated it via ADB to Nougat 7.0, but the truth is that it gives me little performance in screen usage, it would be as long as 3 hours, so I want to downgrade it, I remember when I updated Nougat I had to find the official AT & T ROM Stock that Was compatible to be able to update ie download the ROM that mentioned my previous BASEBAND followed by TO and then named the new BASEBAND.
It was something like that.
ANCIENT BASEBAND? TO G920AUCU6EQCF.
Now my question is the following as I can know which file I should flasehar on my G920A to return to MARSHMALLOW ask because I do not want to cause a softbrick or hardbrick to my device.

[Q] Need to Upgrade from KitKat 4.4.4 rooted to Lollipop 5.0.1

Im trying to upgrade my Note 4 N910T to Lollipop 5.0.1. I've been looking around and haven't found a straight answer. Don't really care if I lose root. I just want the Upgrade. CAN SOMEONE HELP?
And I'm guessing you don't have access to Odin/PC or Mac? Then the only way is for someone to upload a Twrp backup of a lollipop stock based rom. That might work.

U need odin till someone makes a zip to update all. Baseband boot and rom. That would be a huge risk. Get to a pc and use odin.

No, that is just the Kernel, You need to flash the entire Firmware. Remember this is an entirely different OS.
Check out pop rocks forum in development. Has stock rom and auto root with how to.

Samsung has a piece of software called Kies that can be used to upgrade your ROM.

Got your solution, i am also having the same problem, and i use At&t , please can you help if you got your solution.
Follow step 1 of OP ( downloading and flashing build PA2 with Odin) that should give fairly recent build of lollipop.

Hi I'm quite new too in the note 5 section and just got a used mint one because my N6 broke down.
Anyways, you can just do an odin flash for your said model (+ if it's a carrier model, be sure to check too).
If you want a custom rom, you just too just flash TWRP on top of you current rom then flash what ever custom rom you want. I'm currently on XStock V2 going as a daily driver
any have a firmware SM-N920S for delete account samsung note 5
please share link or firmware
Here is the official 7.0 firmware for the N920S.
https://www.sammobile.com/firmwares/galaxy-note5/SM-N920S/
Flash with Odin in download mode.
Just get it downloaded for now. I/someone can elaborate on the instructions once you've acquired the rom. The download time is quite long.

I'm chiming in here because I have been on a rooted version of 5.02 for over a year. I want to update from 5.02 to 6.0 to 7.0 if possible before I sell my phone on e-bay.
Current baseband is G920AUCU2AOF4
IS there a thread with the files need and a path to follow to get there?
Thanks to anyone who can help!
Add one more to this list.....
I rooted my S6 when I first got it 2 years ago and haven't messed with it since. Still running CleanRom 1.1-OE2 5.0.2 baseband AOE2 ......
I also have another S6 thru work. It's all stock. Recently updated to 7.0 and got the itch to update my personal S6 to a more modern version of Android but dont want to loose root.
Is it possible?
Any guide?
Remember it's been a while (almost 2yrs) since I've hacked on a phone so I'm a newb again lol!

Hi guys sorry for my english but i need your help. I tried 20+ methods and firmware and i see all XDA post about but nothing working for me. How i can downgrade my SM-N920C 7.0 csc XSG to any version of android 6.0.1? Thanks in advance.
You may try an older custom 6.0 ROM, but Odin will refuse to install stock firmware.

So there is no way to downgrade my phone? I have knox 0x1, i have no longer guarantee and i can't put the version of firmware that i want?
Nobody kwows how i can do this?
The only way to downgrade your phone now at this point is to install a MM 6.0.1 based custom ROM
You will not be able to do it with official Samsung software

Thanks for your reply. Can you suggest a good rom for me?
I'm just curious, why are you downgrading to 6.0? Are there any issues with the newer Android versions on the Note 5? I have a Note 5 with Extreme Debloated ROM 3.3 with Android 6.0 and i have been thinking of upgrading for a while now but i can't find a better custom ROM since the new custom ROMs have a list of nasty bugs and actually, my current ROM works fine so i'm not sure if Samsung has released any worthy upgrades, for the camera, for example?
