Little genius d2 charging does not make any progress.

1. It is recommended to press and hold the power button 10 seconds, and then turn it off and on again.

2. Whether it is possible to enter the recovery and how to enter the recovery. In the shutdown state, press and hold the volume increase key first, then press and hold the shutdown key, and then let go when the boot screen appears, and you can enter the recovery. If you can enter the recovery, please switch the system and back up the recovered data.
