Is this the new bootloader stuff problem? Can't i downgrade to nougat?

I think because the latest OREO is bootloader V2 and you can't downgrade to V1.

cannot downgrade to nougat..you must install xxu2 only version

Does any nougat firmware have bootloader v2?

I think the only other solution is to install the custom roms.

at&t stock firmware galaxy s7 G930a b4

Does anyone know where I can find the stock firmware for my at&t galaxy s7 SM-930A APB4? I found APB5 but ODIN won't flash it as it's saying its the incorrect matching firmware. I have searched far and wide trying to find the firmware for my phone. It's like I somehow managed to snag the most niche phone on the planet with no stock firmware. Thanks!
PB5 should flash fine. Try a different odin
This is what I get when I try to flash APB5

A quick search I ran found that it seems you may be trying to downgrade. What version were you on prior to this? It sounds like you were either on a T-Mobile firmware or on the latest PI2 firmware (Based on that "Fused 3"). If you don't remember but you haven't taken any updates since you got it, could you provide the date you got it? Then I could help. Thanks.

I was on the newest Sept bootloader update. With the help of a couple people I was able to flash the unlocked firmware.
http://forum.xda-developers.com/att-galaxy-s7/how-to/please-shed-light-att-s7-root-failures-t3481904
Joe3681 is currently uploaded the Sept AT&T firmware so soon I should be able to flash back to at&T and be all set.
Thanks!!

1. You are not using latest Odin version ( 3.13.1 )
2. Due to boot loader versions you can not downgrade from Oreo to nougat.

5th digit from end in your firmware is you current bootloader bit number. Im gonna assume its a 5.
After you have safe strap you can then use safe strap to insall the bit 5 combination bootloader then flash any nougat system IMG that has been extracted from a bit 2 firmware and su and busy box. There are several guides posted on this now. You cannot just flash a nougat firmware which is bit 2.

With safe strap you can downgrade to nougat. As long as its a bit 5 and if your still on the oreo betas which are bit 2 you can downgrade.

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

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.

you can't downgrade 8.1 to 7.0 due to both having different Bootloaders.
