Install Odin, ADB, Fastboot, and Samsung ADB Drivers, 7zip

choco install adb

Get the samsung adb device drivers.

Download Odin.

Note that having upgraded your OS to the latest is a bad idea if you want to root

The XDA people generally figure out the older versions first.

T290XXU3BUC1 has some info on it from Talich52, but not the latest.
