Your unit should be fully charged
OEM unlock and USB Debugging enabled and allow your host computer

Steps:
1. Connect your tablet with your host computer
2. Open prompt and locate to your adb folder (platform-tools) and enter
Code:
adb reboot download
If it doesn't work, look at your tablet to see any prompt to allow your host computer
3. Open your Odin. Make sure auto reboot is not checked (but TWRP isn't overridden). Choose AP and locate your TWRP file. You may see secure check failed. Don't worry. Just press and hold power+volume down+home key together and wait for few seconds.
4. Enter TWRP by pressing power+volume up+home key together. You should see the boot screen. Keep pressing these buttons until the boot screen disappears. You should enter TWRP.
5. Locate your memory card. Flash systemmode SuperSU first, go back, and flash padded image as "boot".
6. (Optional) wipe cache and dalvik cache.
7. Reboot
8. It may take a while to boot up
9. You tablet rooted.

Instructions weren't clear enough, got **** stuck in toaster...

Nah jk, it worked man!

EDIT: This is a lot harder than I thought it would be.... I lost root and did a reset and did it all again. This time after I got it rooted, I got rid of the SuperSU and downloaded the one from market. It updated binary easily.

I keep getting Custom Binary (Recovery) blocked from FRP lock. Did you get this as well?

Make sure you OEM unlock under the developer settings.

Thank you :) Sorry, I haven't rooted an android device since the EVO 4G. Things have changed in the meantime.

Does anyone know how to disable the OTA update notification once I am rooted ?

After Step 3 it takes me to a warning screen with two options 1. Vol up to continue 2. Vol down to restart device.
So I go with option 1 but instead of taking me to TWRP it takes me back to download mode and at the top left corner this is what is shown.

ODIN MODE (In Red)
SECURE DOWNLOAD: ENABLE (In Blue)
MDM DOWNLOADBLOCK: O (In Red)
PRODUCT NAME: SM-T280
CURRENT BIN: CUSTOM
SYSTEM STATUS: CUSTOM
FRP LOCK: OFF
USB Init Start!
USB core reset done

I made sure to uncheck auto reboot but couldn't find anything about TWRP not being overridden so maybe that's the problem, what am I doing wrong?

Sorry for the dumbness, but i have never used this adb, this is only confusing part.
I laptop running windows 10, all drivers, files on sd card as you state.
Any further guidance i would appreciate.
Best wishes

i advise you to search youtube on how to use adb. This is how i learned. Its too complicated to write it. But when you see video its easy. In simplest way adb is cmd opened in adb file. Than in cmd you write commands like adb flash, or adb format and stuff

    Success on a Samsung A6 SM-T280 (version 5.1.1 if memory serves).

    adb makes much problems, better use heimdall

    on my linux (Ubuntu 16.04) adb doesn't recognize my Samsung T280 (but lsusb does), therefore I use heimdall (tested on 3 different PCs). heimdall ist on the repositories.

    sudo apt-get install heimdall (or use synaptic, software-center ...)

    extraxt recovery.img from your TWRP-file,
    reboot your T280 into download mode (press home/vol down/power)

    sudo heimdall flash --RECOVERY /your_path/recovery.img

    Reboot your T280 into recovery mode (press home/vol up/power), TWRP recovery starts.
    Bingo!
