Fastboot to Clean/OSUpdate Motorola Android Devices

Hello all,


We are working with different Motorola Devices running Android like (MC40, ET1, TC55, MC32N0...) and I'd like to know if there's anyway with the Fastboot mode to be able to Clean/OSUpdate a device from a command line using Fastboot/Adb tool.


We have managed to get the device into the Fastboot mode but it is not detected from the command "Fastboot devices"

we get <Waiting for device>.


I would really appreciate if you have a solution for us that would be greatly appreciated.


Thank you
