SM-G920F Downgrade from 7.0 to 6.0.0.1 failed

Hi XDA Members,
I have a very curious problem and hope somebody has an idea what could be wrong.
I have a stock phone that has been updated by a friend to 7.0 but now he wants to go back.
I have flashed a one part stock rom with Odin with complete sucess but after reboot (even showing the erasing process)
the phone boots up and 7.0 is still there and even all the apps and data are still available.
So I tried a 4part stock rom and to my surprise the same thing happened. Odin finished with sucess, phone reboots now it
even installs the bloatware apps and yet it is still running 7.0
I am loosing my mind here. Do I need to flash a pit file? Do I need to root before I flash? What am I doing wrong or will I be stuck with 7.0 forever now?
kind regards
Piko

What's the build number of the rom that you're trying to flash?

You need flash rom which starts with G920FXXU5D or G920FXXS5D if you want to downgrade to 6.0.1
Btw, you don't have to flash 4 part rom.

I have just flashed the G920FXXU5DQA7_G920FDBT5DQA3_G920FXXU5DPL3_HOME.tar.md5 but now if
I start the phone it says "SYSTEM UI STOPPED" when I hit ok - it just says this again and again. Guess this was the wrong
rom once again? I just hope I did not brick the phone yet. Should I flash it again with another ROM? Could you maybe point me to the correct rom I need to download?
many thanks in advance

My main reason is that they changed some core things. I now cannot stream anything from the phone (screen capture) without root. Also some oculus apps just keep crashing all the time.

Hello I have had the same type of trouble only with mine is >/
I have a Samsung Galaxy S5 from Walmart. It's the Straight talk variant SM-S903VLUDU4APH3. MY phone came with 6.0.1 Mm. I flashed the stock rom 4.4.4 kk using Odin3 V.3.10.6 but upon completion of a successful flash the phone does the reboot process but boots into factory recovery and says installing system update. The says erasing then reboots to where I started from same rom, it's like it allows the phone to get the update but then reboots and does a factory reset.

[Updatable][MOD][ROOT][SM-T585/580 stock][6.0-8.1]with TWRP for Odin][2x1]

Hey. I did and successfully tested the mod of stock firmware 6.0 T585XXU2AQA2 SEK region (Ukraine, although it does not matter).
The bottom line is that, you install via Odin the firmware itself and the custom recovery - TWRP , that is, two in one . And after successfully installation firmware via Odin automatically opens immediately TWRP, where I recommend immediately to install SuperSU or latest magisk and then fix or attach below . In result we have a stock firmware with TWRP and root.
Notice. Do factory reset before flashing.
P.S. I tried this mod over current 6.0 rom with installed TWRP. I think if try this mod without installed TWRP you need checked internal memory. If you have 0mb you need to do Format data before flashing supersu and fix.
Downloads : https://www.androidfilehost.com/?fid=673368273298975848
UPDATE. I did mod based on the 8.1 OS firmware
Latest builds no need fix only magisk!
Downloads all builds for SM-T585 and SM-T580(Updatable)
Importantly :
If you have issue with download change your browser to Firefox or use downloader.

Hello, I have a simple question. I am getting the SM-T585 soon and found your thread while searching for TWRP for that tablet. I like the idea of having stock with the custom recovery. I have currently the Tab 9.7 with uses a single file for firmware. The question I have is where in odin do I put the HOME file? or can that one be skipped? Thanks in advance for any responses that answer this. Peace

I have used your "Simplest method to get ROOT & TWRP"(https://forum.xda-developers.com/galaxy-tab-a/how-to/root-t3674409) to get root with SuperSU : it works perfectly.
I have used ODIN to flash TWRP : no problem.
After some modifications on the Settings,I made a BackUP.
Now my question : is it possible to install this Backup via ODIN ?
Thanks for your advice

Boot animation problem

Hi
since i flash my update rom android 7.0
i have two Boot Animation
first is for honor
second is huawei
how remove second one?
plz help me

Try to clean flash your firmware through dload method, trying to be accurate while flashing. Something surely went bad while flashing the update you're talking about. Maybe you flashed the 7.0 for another variant, and now it messed up the firmware. Go on hwmt.ru site -> firmware database, and recover your ROM update package.
You have to pay attention and flash ONLY packages that matches your build number first 9 characters. Like "BLN-L21C432Bxxx", for example, will work only on a BLN-L21C432Bxxx. Flash only packages with PV at the end of the name.

Downgrade Android 8 to 7 - Binary 3?

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.

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.

No, i have LiteRom v. Oreo.
I have latest TWRP of course too.

Bootloader apparently prevents downgrade via Odin, but you can still downgrade via TWRP. You need to flash a custom nougat ROM that includes an older bootloader version.

Odin 3.13. and latest Nougat ROM available for your phone.
Did downgrade without any issues.

You can't downgrade the bootloader.
Stock nougat on an Oreo bootloader will cause problems with wifi, data, and possibly lose the IMEI.

You may be able to run a custom nougat rom on the Oreo bootloader but not a completely stock nougat ROM.
