>If everything work fine, fastboot will detect your device.
then try these command on Command Prompt or minimal adb fastboot
Code:
fastboot devices (if drivers are ok! , it will detect device)
fastboot -w (erase all data/cache)
fastboot reboot (reboot device)>By doing this you will loss every application you have installed before (i mean factory reset- as it wipe "Data&Cache")
