Hello,
This might be a repeat question, but somehow I am not able to get a stable solution.
So I am on G930A ATT and just received Nougat update. However, I would want to go back to Marshmallow 6.0.1
My device is NOT rooted and is locked to ATT.
Any suggestions how can I get back MM 6.0.1 ? Can someone please guide me with detailed steps and tools which can be used.
Thanks.
Baseband Version:
G930AUCU4APJ4
Security Patch:
October 1, 2016
Build NUmber:
MMB29M.G930AUCU4APJ4
Don't think you can as your S7's bootloader is locked meaning downgrading won't work, only upgrading

Thank you for response.. But could you please elaborate a bit.. so I can't downgrade due to the fact that my device is locked to ATT..
If it would have been unlocked, then I could ? Trust me, Nougat update is really annoying and I really want to get rid of it..

It's the bootloader of the US model S7s (Snapdragon) that prevent it, along with preventing flashing custom recovery afaik
Usually you would just use ODIN and grab the ROM you want to flash from updato.com or sammobile but I'm almost certain downgrading is blocked if the bootloader is locked
Not specifically anything to do with your AT&T carrier, it's the phones themselves that are locked
Some info here about snapdragon S7s and their locked bootloader

Hi all, currently running my pixel 2 on latest Dec security patch. 8.1. However due to bug in bootloader (66) unable to unlock the device. I can RMA but still want to know is there any way to revert back OTA update ?
I tried using OTA side load from Recovery but its giving me error saying current timestamp is newer than OTA so failing.
Any tweak to downgrade ?

As far as i know u cant downgrade. Regarding the bug in bootloader unlocking, that has been solved. Restore factory your device and you should be able to unlock bootloader.

I tried but facing issue. Its toggling but at the time of flashing fastboot command its saying locked.
I doubt something broke in 66 version of bootloader. That's why wanted to be on previous version to check the solution

Prolly yeah. But i was able to unlock bootloader on 2 pixel 2 phones running 8.1. mine and my fiance. Prolly weird and rare bug
hello guys , i need some help .
my device is s10e,G970U1 with unlocked bootloader. today i flashed the bl,ap,cp,and csc from oneui3.1 by odin ,and i get a locked bootloader ,so i want to downgrade to the unlocked bootloader,is here anyway to do that .
maybe i do not need the twrp but magisk is a necessity ,but i cannot flash the patched ap in odin ,what can i do now .
i just unblocked the bootloader at feb 14 ,and now i can not use it ,i am not felling well lol.
I haven't figured it out - trying to flash TWRP or flash the Magisk AP soft bricks. The UI 3.1 bootloader version is 5, and the old one is 4 and it won't let you downgrade since it is, technically, locked now. Though KNOX is still obviously tripped, so samsung pay still doesn't work on my watch.
I don't think it can be unlocked again.
G9700 Snapdragon with OneUI 3.1 and bootloader 5 is working with Magisk v22 and OEM unlock too...

If bootloader is same that you want to downgrade to then yes. If your bootloader upgraded from let's say U1 to U2 or S1 to S2 then no you cannot downgrade back to U1 or S1. And on 3.1 on some devices you do lose the bootloader unlock I believe.

Samsung pay didn't work because Knox was tripped, and it still doesn't work on my phone even after being re-locked.
Given the update apparently bypasses the token used to unlock the bootloader, I think we are SOL. People waited years for such an option, and apparently Samsung is working to lock that down.
Now I need to consider if I want to drop $350 for a new S10e still on original firmware, and then another $75 to unlock. I suppose if I can get $150 for my current phone that's not an awful deal.

you are right, but now it is really hard to find a S10e with 8g ram

They are out there. Some new and refurbs for $250-$350.
In any event, I had mixed feelings about rooting in the first place. I pretty much only used it to limit constantly charging my phone to 100% every night. Not going to throw any more money at a phone already over 1.5 years old. A few years from now, I'll probably regret losing root.
hello, I have Galaxy S10E (Snapdragon) SM-G970W with bootloader v6, can anyone help me to unlock this so I could able to flash custom from, TIA.
I'm on the March 1st security patch therefor i cannot use unlock method from afaneh92 and i need to downgrade back to Feb 1st or older security patch. Anything has some instruction and links how i can perform this? Looking to pay for root once im downgraded.
You'll need to reflash it.
A Samsung Experience center at Best Buys can do that.
What issues are you having?

No issue but to get root and unlock boot loader i need to downgrade per this thread https://forum.xda-developers.com/t/...unlock-for-samsung-us-canada-devices.4215101/
How to downgrade from HarmonyOs 2.0 to Android? Wishely 8 one. Is it even possible with locked bootloader?
Thankful in advance for answers.
It is possible
thakns to community for useless.
It's possible to downgrade via hisuite using "update" mode - it allows to downgrade on previous rom version. so, after 3 or 4 flashes I got 8th android 167 rom. what is impossible - flash another rom, just proposed by husiute only. also impossible to unlock the bootloader. sad
