it means you're using the wrong command
use the "fastboot oem device-info" command instead, refer to page 1

Nothing comes up when I run command "fastboot devices". When I run command "adb reboot-bootloader" my phone simply switches off. I've also tried manually booting into bootloader through recovery mode, but the device also switches off. Please what could be wrong?
