title: Reboot MTK device in metamode
body: <p>I have a lenovo s860 with broken power button currently in meta mode. Is there any way to halt it or better reboot it trough shell? As adb doesn't react with offline devices.</p>
  
  <p>Also I cannot remove the devices battery.</p>
  
  <p>(currently using ubuntu)</p>
  
  <p>Any suggestions would be wonderful!</p>
  
  <p>Kind Regards.</p>
