[Need Help] G935A Bootloop - Samsung Galaxy S7 Edge Questions and Answers

Now I've searched just about all of Google on this, but I haven't been able to find a solution yet. Everyone here seems to know the most about this kind of stuff so I figured I'd make an account and explain my situation.
Backstory / How it happened
So, earlier today I figured I'd root my AT&T S7 Edge, I used a tutorial from Max Lee (I can't post links yet but if you need to find it I'm sure you can Google it) to get the job done, and after a while I managed to get the thing rooted. I knew absolutely nothing about what the hell flashing, roms, bricked phones, bootloops etc. were and now I only know a bit about them. So the phone was rooted just fine, I had SuperSU running, and a few other root apps, but then I figured I'd install xposed installer. So I went ahead and downloaded the wrong version (whoops) and it installed its framework and then said it needed to reboot my phone, low and behold we have a bootloop. It stays at the AT&T logo indefinitely if I'd let it. I'll happily admit to that being completely my mistake, I read the warning that it may cause a bootloop but I went ahead and installed it anyway thinking I could fix it if it happened. (This thread is my walk of shame I suppose)
Solutions I've tried
Now that the background has been explained, I'll go through the list of solutions I've tried, mind you I'm no expert at any of this so some of the info I give may seem redundant or nonsensical.
- Rebooting into recovery and clearing cache and factory resetting in every order you can imagine
* Only interesting thing I could find is that it still says custom on both the download mode (the one where you press vol down, power, and home) and when you reboot the phone and it goes through the initial animation, it shows custom with a little settings-looking icon just before it goes through the AT&T animation and takes a **** on my self esteem.
- Waiting ~1 hour for the AT&T logo to change to something other than an AT&T logo (I was desperate)
* Yeah nothing came out of that one...
- Flashing every stock firmware I could find on the internet, with every version of Odin I could find.
* Kept getting the same error, "FAIL! (Auth)". I looked it up and all I found was old threads from 2013 on the Galaxy S4, with some now-irrelevant information, I couldn't seem to get it to work, but I'm positive that's what I need to do unless you guys know another solution. Here's the full log:

Don't know what I did but after that at the download screen it says at the top left "SW REV CHECK FAIL : [aboot]Fused 4 > Binary 2
Sorry for the wall of text, I tried to format it as nicely as possible to make it somewhat readable. If anyone needs more info let me know.

Can you flash TWRP? If you can maybe you can boot into TWRP and then try to flash any rom from XDA and see if it comes alive...

Thank you for the response
I've tried getting TWRP to work, but apparently there still isn't a way to get it working on the AT&T, I was under the impression that it was only for international and Korean versions. I haven't been able to find any version of TWRP that works for my device.
However I just did try some newer stock firmware from, "theandroidsoul" which partially worked, being that I'm desperate and don't know what I'm doing I just tried flashing all three:
G935AUCS4API2 - This one worked more than the others, but it seems at some point it disconnects for whatever reason, causing it to fail. After that my phone gave me the whole "You messed up go use smart switch" deal, and smart switch was saying my device was unsupported. That said I'm not sure what is causing the fake USB disconnect cause I can hear the windows sound for the USB disconnecting, but I'm not sure why.
Here's the log:

I found it interesting that it got even less far than before.
G935AUCS2APH1 - Stopped at lksecapp.mbn then went to FAIL! (Auth). There was no disconnect or reconnect
G935AATT2APG1 - Same as above

I seem to be stuck in a similar situation. Did you ever find a fix?

I had the at&t s7 edge before and had the same problem but not sure if it was the same odin error.
But this is how you flash a stock rom on the at&t:
-You must use the princecomsy odin (search for it on google)
-Here is the stock rom with the latest security update (type "G935AUCS4BRA1" in the google search bar)
(I wasn't allowed to post links)
unzip and flash
tell me how it goes

I really need help, it is bricked.
Use this app from your computer, with your phone in download mode. It saved me. I believe it's because you may be trying to flash to a previous version of firmware. http://support-us.samsung.com/VerizonSoftwareUpdateWin
Did you get this fixed?

This error has happened to me before. Don't use the HOME CSC file, use the other one that wipes your phone. The Home CSC never worked for some reason.

S7 Edge Odin write fails - Samsung Smart Switch cannot recover firmware due to error

SM-935F from XSG region. Unlocked and Qualcomm processor. Never enabled debugging mode or OEM in developer tools. I tried to flash my phone with the following firmware. However when I tried to do it, Odin failed. Also Smart Switch Samsung doesn't initiate/emergency recovery says cannot proceed due to an error.
​Samsung Smart Switch shows the below data while trying to initiate the recovery which eventually fails. ​
PDA: QH8 / CSC: QG2 / PHONE:QG3 (COS)
Phone doesn't go to recovery mode at all. I can get it to Download mode however everytime I try to run a firmware, it shows "Complete(Write) operation failed."
Also tried to do abd enable reboot which said "device(null) not found". Just need this working and I don't care about losing data. Please let me know how to proceed.

Cant reboot Phone or power it off and back on without removing Battery

Solved!
now im sure the emmc chip a.k.a. the storage on the mainboard is not working correctly I have to buy a new Mainboard. Does anyone know how much note 4 phones are affected by this?
If I try to reboot my Phone is wont start again. I need to remove the battery and wait at least 20 sec before I can boot up the device.
My phone curently operates with RR/N (restruction remix nugat) I have instaled this firmware over TWRP accoring tho this tread https://forum.xda-developers.com/note-4/snapdragon-dev/rom-resurrection-remix-5-8-0-t3523130
I had installed this rom on the same day I recived the phone (I dont think the error comes from the rom)
even in TWRP the boot to system doesn't work it seems like the phone stucks somewhere while reboot.
somtimes when I boot up the phone it automaticaly goes in the download mode and at the top line stands:
coud not do normal boot
mmc_read failed
In odin sometimes the feedback is PASS! and Sometimes failed
I have downloaded modem, bootloader and Stock_ROM from here https://androidfilehost.com/?w=files&flid=26335 and flashed it over odin:

the auto reboot funktion from odin seems to work well.
sometimes, after removing the battery and ~20 sec waiting the phone does not respond to the press on the powerbuton and seems to be dead. but if I plug it over usb in to my windows computer the system sound corresponding to "Error in device connection" comes.
After removing the Battery and waiting around 20 min sometimes less, I can sometimes turn it on
what should I do? buy a new Motherboard on ebay or is there something i can doo to fix it?
thank for your responses
PS: sorry for my bad english i'm from switzerland and 16 yo

kies is useless. your drivers are properly installed if Odin recognizes your device.
Download Odin 3.13.1 and try it again
Thanks I'll try when I am back home. I Cann only access download mode BTW. Else I stuck in a boot loop with this blue installing update screen.

as long as you can get to download mode, youre in good shape. From there, its merely a try-and-fail process of different Odin and firmware versions
Ty I was getting pretty despred after hours of fails and disappointment

it can get that way especially if youre downloading your firmwares from sammobile.com/firmwares directly. Takes FOREVAAAAAAR and then when it fails it gets SUPER irritating. Get the Frija firmware download tool here and the speed difference will blow you away. There is another firmware download tool out there too and i have it on my computer at home, but i cant remember what its called and the Frija tool is as good as that other tool anyways.
