i think that the second raspberry pi3B power cable is not good, it is able to continue with installing after i have changeed my power cable.
i have checked the xiaomi socket with 3USB, it's only output 2A. i have used ipad charger to take the place of xiaomi socket.

ubuntu@ubuntu:~$ sudo sh -c 'echo 0 > /sys/class/leds/led1/brightness' ubuntu@ubuntu:~$ sudo sh -c 'echo 0 > /sys/class/leds/led0/brightness'
Yes, you can turn off the LEDs on the raspberry pi model 3. This was tested on the raspberry pi model 3 B+ The line below is used to turn off the power LED sudo sh -c 'echo 0 > /sys/class/leds/led1/brightness' The line below is used to turn off the action LED sudo sh -c 'echo 0 > /sys/class/leds/led0/brightness'
reference to How do I control the leds of raspberry 3?
The LED can be turned on and off using the 'brightness' file. The minimum brightness is 0, and the maximum is 255. As there is no variable brightness support, any value greater than 0 will turn the LED on. echo 1 >/sys/class/leds/led0/brightness echo 0 >/sys/class/leds/led0/brightness
