@SteeMan you are really good person  it works when I selected through `Update and Backup` app. Thanks a lot

Often there is an 'update' app in Android that will do the same thing as the reset button.  But note that not all apps named 'update' will do what is needed.  But check if you have an update app and see if you can use it to run the aml_autoscript.zip  located in the /boot directory of your armbian sdcard.  This should cause the box to reboot and have the same effect as the reset button.
