a5ltechn: Rebooting weirdness

[Dobby233Liu]

• Attempting to reboot to system in system will actually shut down the device
• You will not get out of recovery normally after entering it from system
  IDK if this happens on stock OS too
  To get out, perform any kind of flashing action in download mode, then manually reboot
