While the tab is switched off, press the back button. Keep it pressed and connect your tab to your PC. Now, while keeping the back button pressed and tab connected to PC press the power button 10 times as fast as possible.
Your PC will now detect the tab. You will see that it is searching for drivers if you did this for the first time. It will fail. But don’t worry. We will fix this now.
To fix this, press the windows key on the keyboard + R. You’ll see that a Run dialogue pops up.
