"reboot update" error on Mecool M8S PRO L 4K TV Box Amlogic S912

  • Bought the Mecool M8S PRO L 4K TV Box Amlogic S912. This doesnt have a hard reset button

    So I have installed the terminal. Previous to that flashed LE to memory card and also copied the dtb.img from device tree. Im having issues in rebooting.

    $pwd

    $/data/data/com.termux/files/home


    I do reboot update

    It says "No command reboot found"

    From where should I run this?

    Note:- I only copied the remote.conf from Index of /MECOOL/ as mine is pro L
