As mentioned, when you go to download mode on your device and when you type fastboot oem unlock, it get stuck on the command, and there's no serial when you type fastboot devices as well which means that the fastboot driver is not recognized by your PC, in this case, Nokia is blocking OEM unlocking from its side and.
