A couple ways that have worked for me:

1. Turn off the screen by pressing the power key. Then hold the circle button, volume down, and the power button. Push the reset button with the stylus.

2. Screen can be on. Hold Volume Down and Circle button. Hit reset button. While still holding the 2 buttons, immediately hold down on the power button as well.

Both times, continue holding all 3 buttons until you get a grey screen with blue letters
