no because ur bootloader will block it cuz ur bootloader is a higher version than nougat
I thought maybe there is a nougat firmware with the new bootloader like the S7 \S7 edge has
You can only down grade to N if you did not flash bootloader.
I skip flashing bootloader and have went back to N
Personally I lost too much going to Oreo.
the was an ota update so I guess the bootloader has been updated

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

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

Oh my god. That did the trick - and I thought it was over. How did you know what version to flash for the downgrade?
And is there anything good I can do for you to say thank you for helping me out this much? Seriously you helped me soo much.

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.

I prefer the speed and performance of marshmallow on the S7. Where are the correct files I should flash in Odin and which version of Odin should I be using to flash Android 6?
So apparently the camera isn't working after downgrade to 6?
Not something I'm willing to deal with unless the issue has been solved.
You can't downgrade snapdragon S7 models (G930U/T/V/A/P) due to the locked bootloader
Any downgrading would only work on the G930F with OEM unlock
Help root or downgrade or both?

I have a sm-g930u factory unlocked and Im also trying to get all i need to downgrade from oreo which is havoc on my battery and i dont know if its better to downgrade to laterst nougat or root it and take care of bloatware to help battery drain yet the problem will persist which is that the upgrade is designed for s8 and s9 with octacore processor and the s7 is working harder with a quad core so temp will always be hotter than before and slower than with nougat . Any help with proper step by step in downgrading my factory unlocked phone would be appreciated and any root links as i havent done it in years.

You can downgrade. You just can't root.

You can downgrade any version bit loader by flashing the combo firmware and the rooting combo firmware then flash stock nougat system image its basically what the root method is for Rev11/B. If you are just on nougat then you would have to get the combo firmware that matches the bootloader version you have because if you flash my rev11/B root method you are forever stuck on that bootloader and can never use nougat again or have oreo root as there is no eng root boot.img available for oreo root on rev11/B bootloader

you can downgrade too marshmallow from any version you have because combo firmware for s7 is marshmallow based and its available for all bootloader versions. You just use the combo bootloaders and boot.img and stock system image then root it
If your still on bit 4 you can just flash stock bit 4 marsmallow and root with marshmallow eng root img
I installed Superman Oreo rom and want to go back to the Nougat version, I wiped the phone and flashed Nougat but it just got stuck in a boot loop.It seems the bootloader was updated to version 3 and nougat uses version 2.Does anyone know how I can fix this? I tried flashing the bootloader and modem through Odin but it gives an error.
I want to do the same. Superman 3.10 oreo to nougat 2.90
Have I to downgrade the bootloader?
Thanks for answer

I tried everything i could find and nothing worked i just stuck with 3.10
Try flash first Stock ROM Nougat than Superman 2.90 ;]
I had Oreo Stock and back to Nougat Stock without problems.
Superman 2.90 could need Nougat Stock ROM
Same here.
Was using SuperMan 3.1.0 but was disappointed with Oreo.
installed stock Nougat ROM via odin 3.13, then TWRP and root, nxt SuperMan 2.9.0.
need time and patience.
Make sure your battery is fully charged. and you have stock latest NOUGAT ROM with adequate AP,BL,CP,CSC.
If you have FAIL at 1st attempt, do it again.
I had 2 FAILs before it PASSED.
Tip:
When your Odin process will FAIL, but process isnt finished yet, disconnect phone from laptop and turn off holding power button, Phone will restart into DL mode with big triangle on it saying to use SmartSwitch for PC to recover the OS.
turn it of again and when screen is off but before the vibra, press and hold PWR+Vol DWN+Home, phone will go into normal DLmode, connect then into laptop and press Vol UP to confirm Odin Mode in Download Mode.
Then using Odin, install OEM Nougat OS.
This is the method that worked for me and had successfully installed Nougat.
After that, boot the system, unlock the Dev options in setting and turn on OEM unlock before you go for TWRP and root.
hope it will help.
Goodluck.

Hope this helps:
Go back to Oreo or whatever ROM you can use
Goto settings > developer options
Enable OEM unlock
Now try flashing nougat if you stuck on bootloop then install a custom ROM that is nougat, then try to flash stock nougat. If it still doesn't work there is nothing I can do use a custom nougat ROM. I recommend ultimate nougat

So is there any method to downgrade the ****ing bootloader?
Mine is ver.3 and need to flash ver.2.
I realy not want to stuck on Oreo. Oreo realy have no Benefits.
There is no way to downgrade the bootloader. Samsung blocked bootloader downgrades starting with the S3.
But why cant we just install the nougat bootloader and modem as .zip from twrp if we are on an Oreo rom?
Is this not possible?
hello everyone,
i have S8+ with android 7 installed, not rooted and still didnt get any OTA for either oreo or Pie, so i decided to do it manually but i wanna make sure of the steps since it's been a while for me not flashing anything.
first thing i should know is that this update is going to wipe my phone due to the bootloader update
and about that bootloader update, should i flash pie bootloader first or just flash a stock ROM with odin that includes bootloader file ?
any help with this issue is much appreciated

If you are going to update with Odin flash full firmware. ( 4 files )
As for wiping your phone when you unzip the downloaded firmware there will be 2 CSC files.
CSC - Clean install will wipe your data ( same as factory reset )
Home CSC - Dirty install should keep your data
Always do a backup before doing anything.
Note: Make sure after you upgrade your firmware to update your apps so that they will be comparable with new firmware.
Is there any way to downgrade binary 6 to 3 or just downgrade android oreo to marshmallow (ik its the same thing)
If someone ask "why?" touchwiz
It is not possible to lower the binary. This is what it was introduced for.
If the phone allows you to unlock the bootloader and flash TWRP and Custom ROM, then you can try to find a ROM based on an earlier firmware version, but it will no longer be a fully trusted firmware.
