Green light seen during flashing.

I followed these instructions from the librem5-flash-image script:

            Turn all Hardware-Kill-Switches off
            Remove battery
            Hold volume-up
            Insert the USB-c cable: (red light blinks, no green light)
            Reinsert the battery: (red light is constantly on, the script will continue)

This happened in reality (if I remember correctly):

            Turn all Hardware-Kill-Switches off
            Remove battery
            Hold volume-up
            Insert the USB-c cable: (red light blinks, no green light, after a while alternating green and yellow light, the script will continue)
            Reinsert the battery: (yellow light is constantly on)
