help Bootloader unlock and connection adb failed

I have a problem,

By unlocking the bootloader.

I first checked if it works and I can unlock the bootloader

then I'm on sony and got me because unlock code for bootloader me

then I downloaded ADB, with the respective drivers for the Sony experia z3 D6603 downloaded

then I checked whether the connection is now exactly that is a problem it is a connection but if I want to fastboot then nothing happens

I entered that
adb reboot bootloader

and then you do not care

I need a support as soon as possible what I can do there

Since I have to root the device for a friend

I thought his bootloader would be unlocked
