Work needs SM-T837A to run Oreo 8.1 for compatibility with MDM. OOTB 9.0...

We got some new tablets and apparently Android 9.0 breaks functionality with a feature we need in our MDM. Anyway to flash back to 8.1?
I used to flash to and from different roms with my Galaxy S3 but that was a young mans game and I'm out of the loop now.

SM-A505GT, latest update (Android 11). Where can I find a safe root guide?

I can't find any guide for this model (SM-A505GT)
Any help is much appreciated

Also i could not find a full guide for a505f. They all pass some steps. I guess unlocking the boatloader is the first step. But all guides starting with "make sure the oem is greyed out" how to do that. If there were understandable guides stey by step, many people would root. We need guides like explaning a child. 1,2,3.... with all steps. And i see that many people having issues with custom roms. Is it possible to root stock rom ? Android 11 ui 3.1. I just wanna have root access.

Samsung Note 10 + N975U won`t update

Hi all.....
I live in middle east and I bought unlooked Samsung Note 10 + USA version with Android 9 and I don't have AT&T sim card so when I tried to update through OTA it says "you have the last update" but others got android 11 and I still at android
is there any solution ? Please help

Updates ( read: patches ) get rolled by OEM / carrier if they deem it necessary.
What you probably mean is Upgrading from Android 9 to Android 11. IMO this you only can achive by flashing a Custom ROM based on Android 11 what is suitable to your phone.

Thanks for your answering I meant that my phone stuck at Android 9 and I couldn't upgrade since I had the phone So my question was can I upgrade to Android 11 by Odin and still get official updates?
And I actually didn't know what is the right rom for my phone

try oneUI 4.0 and rollback ?

Hi,
I am reading horrible stories about the oneui 4.0 update causing for a lot of trouble ?
For that reason i have not updated since 1 dec ( = one ui 4.0 update ).
Is there an easy way of trying the update on my device and rolling back when the update is too problematic ?
thanks,
tom

I would not. Wait until the bugs are worked out.
I'm still running on Android 9 and 10 on my 2 N10+'s with no issues. Not going change the firmware as they run well... and are fulfilling their mission.
You rolled the dice every time you update especially when the device is running well.

thanks for the reply, but i am very concerned about security updates.
The phone hasn't received any since 1 December since they are combined with the one UI update.
Is there a way you can install samsung security updates separately ?

[FIRMWARE] [ODIN] Samsung Galaxy in softbrick after Android update

Yesterday I decided to upgrade the Android version of my Samsung Galaxy A50 from 9 Pie to 10 (and after that I wanted to upgrade it to Android 11), buy after the installing process of Android 10 finished, my phone was not able to start anymore, showing me the Android Recovery page and the error “/system/bin/tune2fs is missing”. The upgrade to Android 10 didn’t work.
I think I should install some firmware with Odin, but I never did that before. Also, my phone isn’t rooted. Can someone tell me how to do it? And, in view of the fact that I want Android 11 at the end, should I search for Android 9, 10 or 11 firmware? Can you “jump” from Android 9 to 11?
