Downgrade G900A OF2 to KitKat or remove lock samsung account - AT&T Samsung Galaxy S 5

My friend have a refurbished G900A (OF2), and when he tried to start to configure his phone it appeared the message "anormal reset", so we decided to downgrade it but we haven't found any solution (and we researched for hours).
The problem is, the bootloader is locked, and my friend discovered after installing "Supersu", that the phone is rooted.
So, I'm asking for your help to find a solution, or at least find how to change that "anormal reset" message, because when he tried to use any solution on the internet (specially YouTube), the phone responds "Error processing" (or something like that, it's in spanish) when he tries to insert his or my Samsung account, or doesn't allow to start Samsung Apps when he tries to change the "Accesibility" options.
Best regards from Chile!
(And sorry about my english)

Additional info
By the way, I started the phone in bootloader mode. Odin starts and get stucked in "Downloading".

Reactivation lock may be your problem. If you can get it to boot up disable it in settings

Thanks for your answer!
I tried to do that, but when I unchecked the box to disable the lock, the phone checks it again.
So now I'm thinking as a desperate option, to bring the phone to a Samsung Official service center.

I brought the phone to a Samsung Service Center, and they can't fix the phone, because the AT&T Model doesn't have support in my country.
Is there any way to remove the samsung account lock in the OF2 version?

Your friend might have gotten conned. I once bought a refurbished phone and it had an IMEI lock on it, meaning it was either lost or stolen. So it's possibly a similar situation...

Depends on what version you are on. I am currently on 5.0.1 and used pingpongroot
As far as I'm aware, ping-pong root has been the only root method for AT&T S6. It worked on the first 2 builds of 5.0.2. If you are on a later 5.0.2 or any 5.1.1 build, there is currently no known root method. Read the ping-pong root thread for more details.

Try a different att store or a bestbuy with a Samsung experience shop inside. Bestbuy with SE store is your best bet

Samsung Galaxy Note 5, i need help ASAP.

This all started when i accidentally deleted a text message that i needed, i did a search on google how to recover a text message. I downloaded some software that was recommended on a reputable site, i scanned the file with Kaspersky etc and it was fine.
The software was pretty straight forward to use, you basically needed to go into developer mode to enable debugging which was easy enough and the software did the rest, it said on the site that rooting wasn't needed.
Anyway, it didn't recover the text message. After i disconnected my Note 5 from the PC i had this Security notification warning coming up which says "Unauthorised actions have been detected, restart your device", i've done that several times and nothing happens. I've tried going into the phone updates but it won't even allow me to connect to the update servers as i get a message which says
"The operating system on your device has been modified in an unathorised way. Try downloading software updates using Smart Switch on your PC or visit a customer service centre".
I've tried doing updates via Smart Switch but i can't even check if i'm upto date or not, i tried a hard reset via the home button, volume up switch and the power button but that hasn't done anything. The phone seems to function normally but it has this constant security notification being displayed.
I've tried going into the download mode to check the knox counter but a big yellow triangle comes up first with an exclamation mark inside it with a white android man underneath and it says under that "No Command , it pauses for a while then the boot and reset option list eventually appears, it's got yellow writing above the list saying Android Recovery but nowhere does it say the knox counter.
Before the above this is a UAE Note5 that is standard and hasn't been rooted, it's a stock phone.
Any ideas as to what i can try or do next ?
Do you have a link to this software you used?
One was called FonePaw, that didn't work so the one that i tried after seem to give me all these issues, that one was called Dr.Fone Toolkit for Android, version 8.3.3.64
It wouldn't let me post a link saying something about me being a new member.
This is the strange thing, ive been into the download screen a few times via the home/volume up and power button. Where normally you get a nice neat list with the actions you can do, their was a lot of yellow text at the top left, the actual list was underneath all that yellow text, it didn't have the Knox line where it usually is. I then downloaded PhoneInfo *Samsung* and that gave me a lot of info, it said the Knox was 0x0

Thanks Darren, i've updated the info from the download screen above.
One quick question, i've never flashed a phone before, i've flashed graphics cards etc. Do you need to remove the SIM card ?
Thanks Darren, do you have a link to the latest genuine version of Odin, sorry to be a pain mate, it's just i aint done it before and want to make sure i have the right version lol

No, you do not need to remove the SIM Card.
Here is a link to Odin 3.12.3 in my OneDrive account...

Works perfectly and is a stock version of Odin with no modifications.

Thanks for all the help.
I flashed the phone in Odin with a stock ROM, the same UAE one that was previously on the phone. Touch Wood everything seems to be working fine with no error messages.
All sorted.....

Help! Downgrade from Oreo N950F

Hello everyone, I have a problem, since I updated my phone to android "Oreo", it started to fail, it restarted, the battery lasts less, and sometimes it has many "Lags".
Download a version from "Sammobile", but when I try to go back to the previous version the process fails.
In "Oreo" I did all the "Wipe", but the problems aren't solved, since time later they come back out. I want to go back to android "Nougat", my "Note 8" was very good with that system, it even lasted me all day.
I attach this information:
FRP LOCK: ON
OEM LOCK: ON
Secure Download: ENABLE
Warranty VOID: 1 (0x500)

Well since you didn't read before upgrading your phone, now you're screwed and staying on Oreo because Samsung blocked downgrading.. No matter how much you try it's just going to keep failing!! All you can do now is try to fix all the problems you think it has and make the best of it and next time read about what you're planning to do first so you don't end up in this situation again!!
As mr mike said, there is absolutely no way for going back to 7.1.1 once you upgrade to 8.0.0, no way, but, you may try to flash another oreo firmware with an equal or higher bootloader version, there should be one that works for you, be patient and try

The TWRP you are trying to flash is for the N950F only.
The thread below is for your device, make sure to read the whole OP. Too, make sure you understand what rooting will do, Samsung pay etc will no longer work

I can't help you further as it is not a device I am aware of how to root.

you have to wait 168 hours with the phone on (no reboots) and then the toggle will appear in dev settings

you bet. that was the method a while ago at least. also, look for zip files you can flash in TWRP to make it to where that stupid 168 hour thing never pops up again. I think it was called the Chimera tool or something like that. and be sure to use the thanks button when someone helps you
