To unlock bootloader:
you must start your phone normally. (if it was already configured, re initialize it) . When asked, configure wifi, ignore google configuration and so on BUT when its asked by google, you must configure the pin code.
Then ignore the rest.
When configuration is finished, open Settings. Go to the last section: "about the phone " and open it.
Locate "information about the software". Open it. Locate "Version number".
Click 7 times on it to activate developpers options. You'll see a message saying its activated.
Then go back to Settings you will notice a new section called "developpers options".
Open it. You'll see OEM unlock option. If not activated, do it. AND activate usb debugging too.
Then restart the phone. IF it worked normally you'll see a message on start screen about bootloader.
Shut down the phone. And start it in download mode as i explained previously
lauch Odin with administrator privilege
Et voilà
