H-2 Boot Mode

This will cover how to put the H-2 into boot mode.

This is needed to force the device into boot mode to reflash the firmware.

Boot button only

You can enter boot mode using only the boot button.

Make sure that the battery is removed prior to putting it in boot mode

Make sure that there is no battery in the device. The battery will prevent it from entering boot mode.

1. Disconnect your H-2 from power. With the device facing you, locate the boot button. It’s the small black button on the right.

2. Plug in a USB cable that supports power and data into your computer.

3. Push and hold the boot button (the right button). While still holding the button down, plug in a USB-C cable into the USB-C port of your H-2 then let go of the button.

Boot and reset buttons

You can also enter boot mode with the boot and reset buttons while the device is plugged in.

1. Plug in a USB cable that supports power and data into your computer and connect the other end to your H-2. With the device facing you, locate the reset (left) and boot (right) buttons.

2. Put your H-2 in boot mode. Use both buttons, in this order:

  • Press and hold the boot button (the right button). Keep holding it.
  • While you're still holding boot, press and release the reset button (the left button).
  • Let go of boot.

Keep holding boot the whole time

Pressing reset by itself only restarts the H-2. It goes into boot mode only when boot is held down while you press and release reset.
