G920T : "dm-verity verification failed..." Help.

Hello, I currently have a G920T that had been working alright for quite some time. The problem is that yesterday while using it normally, it suddenly froze. Thought it was the app, but saw it was the phone itself. Thus, I decide to turn it on again. When I do that, the phone does not continue after the logo and has the LED light white, while blinking on an off. When I manage to enter the Android Recovery menu it gives me the error shown in the title. The phone's rooted and was unlocked, so I could use it with AT&T.
I attempted doing a full reset, upgraded it to Nougat, and I am still stuck. Any help's appreciated in advanced.
Would like to say, when I installed the official Nougat Upgrade for my phone, upon starting, it began installing some things and then preceded to start Deleting. Afterwards, it just froze again. Did I do something wrong?
To get past this issue you have to Root with SuperSU, this will patch the Kernel to disable DM-Verity and will allow you to boot normally.
If you don't want to get rooted then reflash stock firmware via odin. never do OTA updates as i have always say the come "Dirty"
EDIT: Sorry didn't read you were rooted, just re-root again with SuperSU (To get your Kernel patched again) for DM-Verity

So I use (what I previously used) cf-autoroot again? I ask this, since it seems their website have the recovery for marshmallow version and not for nougat (if I am not able to downgrade to 6).

Root with TWRP and superSU zip, i don't recommend CF-AutoRoot
Before flashing the Zip do the following on a Terminal in TWRP
Mount o- bind /dev/urandom /dev/random

You can use CF-AutoRoot for 6.0.1 and 7.0.

When I use CF-Autoroot and attempt to boot it into recovery I get the following message, "recovery is not seandroid enforcing".
So I'd take I try installing a custom ROM first before attempting to start it in recovery?

Oh, that means CF-AutoRoot has not updated to work on 6.0 & 7.0 bootloader for G920T (It is updated and working on 6.0.1 & 7.0 for G920F)
Flash the stock ROM again. After that, flash TWRP and than flash latest SuperSU zip via TWRP.

I tried doing that, but wouldn't get past the main ROM's screen. I tried a custom ROM then (I think nemesis or such) and lasted longer, but again froze and loops with the white LED light on.
Any suggestions?

downgrade from Oreo to Nougat - success but can't to install custom rom

Hi all
Currently on Batman V2.0.0 Oreo - S8+ SM-G955F
Reason for change is due to poor battery life and intermittent fingerprint scanner.
I have downloaded stock Nougat 7.0 - G955FXXU1AQF7_G955FOXM1AQF7_BTU, flashed this via Odin and everything booted up fine. The next step was to root and device and install twrp.
1. Downloaded TWRP and installed
2. Installed dm-verity and force encryption disabler
3. flashed Magisk.zip
had full access to twrp and had root.
Now i am trying to flash batman V1.50 via twrp. The installation goes fine, when rebooted it stays on the Samsung screen. it will not let me load a OS. The system states no OS installed. i have tried with 2 other Nougat roms and still no joy, i even flashed the correct bootloader and modem and still hangs on logo. is there something i am missing here? all your help would be appreciated. Oreo update is not for me.
Restored a twrp backup to go back to my working version of batman oero again, stuck with this until a solution

What command you use. You have Android 7 or 8 right now
Android 7.0 I have been using that app. That boots it into recovery then tries to flash it. I tried to get the adb cmd to work but it doesn't find the file. I know this all sounds like gibberish but that's why I'm lost.

Downgrade Android 8 to 7 - Binary 3?

Hello,
I am attempting to downgrade from Android 8 to 7 on Galaxy S7. When I attempt to flash the old firmware I get the error 'Device 3 - Binary 2'. Does anyone know if there is a workaround for this yet?

Odin will not let you flashback to a previous boot loader version, you have to do it through TWRP. So either flash the nougat firmware with TWRP first or any nougat based rom, then flash nougat via odin which will remove root and TWRP.

Are there any instructions for this?
Will secure apps (Banking etc) work again after removing root?
I was under the impression you could via Odin if OEM unlock was enabled, without needing TWRP or root. https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-downgrade-android-oreo-8-0-t3821495
edit: As for banking, if you go root then flash back to stock you should have no issues. Even if you stay root, things like Magisk will hide root status from apps and pass safetynet. Your biggest issue would be the loss of Knox, which voids warranty and breaks some Samsung apps.

It is not possible as per some of the replies to that thread. I spent a few hours playing TWRP yesterday and it was not possible either.

Ok so listen, it can be done as i said but it's not easy. The choice you have of course before attempting this is to just install a android 7 custom ROM? many nougat ROMs are just stock with the bloatware removed and the boot-loader version isn't checked during flash.
Here's another way to go back, i can't guarantee it will work though i haven't tried it on an S7.
Downgrade to an older firmware with an older bootloader even if one keeps the newer bootloader on his device.
So what's how's it done?
Download the firmware file (.tar) which you want to downgrade to and open it with an archiver application (7zip). Extracts all the files to a folder and repacks them again in a .tar file but leaving every file out which ends in .bin (e.g. sboot.bin etc.). This .tar file can now be flashed like any other firmware file via Odin and it should run through it without any problems.
Hope this helps.
