Firmware Downgrade from Oreo - Samsung Galaxy S8+ Questions & Answers

Hello XDA community,
I got an interesting notification from Samsung while browsing through the internet.
Android wants me to "update" to their 7.0 Nougat firmware with the december security patch. So far so good, firmware updates by samsung take ages anyway but there is a big problem
I already flashed to Oreo 8.0 with Odin 3.1
My question is how can I remove that forced software update? Samsung support told me Odin wouldn't be an official programm and that they won't help me with rooted devices..

From the little I've read here at XDA, the BL has not been blocked, so you should be able to re-flash the firmware you wish.

Updates for 6.0.1 without installing 7.0

I had installed Nougat as soon as it was available for my S7 and never really liked the battery life. Maybe I could have tried to fix it but instead I downgraded back to 6.0.1 through Odin.
So far every thing is fine. But the first and only update that I received is the 7.0 upgrade again. Ofcourse I didn't install it this time. But it looks like I'm not getting any other updates or patches now.
When I look at the Security patch level, that is from Dec. 2016.
I think I don't get any updates for 6.0.1 now because the is an upgrade waiting to be downloaded and installed.
Is that how it works or am I missing something.
Thanks.

Install the last (newest) 6.0.1 ROM, and that is the last update you will get for it, it's not like Windows
If you want to stay up to date with security updates you MUST be running the latest available ROM, which is 7.0
Thanks.
I have the latest rom I could find. And was hoping I would get at least the latest security updates for 6.0.1.
Looks like I will have an other look at 7.0 again soon.

Nope, mobile OS's are discontinued once a new major OS version is released
iOS/WP/Android all the same

No new updates

Hello
Forgive my noob question but I searched a lot and couldn't find an answer
I bought my phone about 4 months ago
It's build number is BLL-L22C636B160(marshmallow)
Until now,I didn't get the OTA update
I downloaded the build BLL-L22C636B384
It said : fullOTA-MF
What does MF means? (I'm not a native speaker so I couldn't know)
I jst want to check :is this the official nougat update?
And could anything wrong happen to my device if I updated it instead of waiting for the OTA update?
Thanks a lot
Use firmware finder for update and check for firmware access if approved then use in app proxy

how to update ATT S8+ G955U model G955USQU3CRD7 to CRE9 ?

Hi ,
I am a new android user and have never used odin before. My ATT S8+ is on CRD7(may security)software right now which I downloaded from Samsung science firmware website. I would like to know how I can update to latest ATT release so that I can receive OTA updates in future. Would appreciate if someone can provide me with download links and steps to install the software.
Thanks,

Locate the updated and correct firmware. Perhaps via Samware.
Flash with updated Odin, as normally done. It is pretty straight forward. Checkout the how to's on this site, via search. Search is your friend.
Note. if you are updating to CRED version OS, you will not be able to downgrade.
Voila.

Samsung Galaxy S10e Downgrade 11-10 or even 9?

Hello dear XDA forum friends, I have one question, I was Apple user for a long time and I got Galaxy s10e.
Its a nice phone but it dont work well on Android 11, battery drain fast, phone is to hot and more and more..
I was wondering if I can downgrade it back to 9 or at least 10?
Long time ago I remember I used to flash custom ROMS and downgrade old Android phones but looks like now if they lock Bootloader you stack where you are.
So here are some infos:
One UI Version 3.1
Android 11
Baseband Version G970FXXSBFUE6
Kernel Version 4.14.113-21644994
Build number RP1A.200720.012.G970FXXSBFUF3
Knox 3.7 API level 33 TIMA 4.1.0 DualDAR 1.3.0
Service provider software version SAOMC_SM-970F_ODX_CRO_RR_0008 CRO/DHR,CRO/CRO
Welcome to XDA
Congratulations on ditching the sour Apple.
Post on that device's forum for best results.
The firmware you have probably also upgraded the boot loader version which may make it impossible to down grade. I'm have zero experience flashing these so I may be mistaken or a workaround.
Try a factory reset unless you already have after the upgrade or if you used SmartSwitch to transfer data from another model.
I've tried to downgrade even an Exynos phone- sadly Odin couldn't do it due to bootloader
Nope, the last update that would have allowed you to downgrade to Android 10 came out back in February
