2) Enable USB Debugging Mode on tablet to connect the Android device with the computer and use the Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option then check USB Debugging Mode.]
3) As the tutorial might wipe out all data of the Galaxy tablet, create a backup. If the device is having any custom recoveries such as CWM/TWRP already installed then backup the data using the recovery.
4) The Galaxy Tab should have above 80% battery charge.

Steps to root Galaxy Tab 3 7.0 (SM-T210/T210R) on Android 4.1.2
Step-1: Download root package for Galaxy Tab 3 7.0 to the computer
File name: prerooted.tar.md5
Step-2: Download Odin v3.07. Extract the Odin zip to get Odin3 v3.07.exe

Also, the ID:COM box in Odin will turn blue with the COM port number indicating successful connection
Note: If the Added message does not come then try another USB port, try the one located at the back side of the computer. In case Odin still fails to recognise the device then re-install USB driver.
