Sony Xperia XZ: unlock bootloader FAILED (remote: Not necessary) - Android Q&A, Help & Troubleshooting

Hi Guys
I'm trying to root my device "Sony Xperia XZ (F8332)", and I have followed the steps in the develpoer.sonymobile.com, in the last step I faced this error:
..
..
C:..\sdk\platform-tools> fastboot devices
CB512CF1A4 fastboot
C:..\sdk\platform-tools> fastboot -i 0x0fce oem unlock 0x**********************
...
FAILED (remote: Not necessary)
finished. total time: 0.023s
Then turned on the device and then it did a reset factory, and I found the status for the OEM unlocking in the developer option says that the bootloader is already unlocked.
What does this error mean?
What I have to do to complete the root ?

[Q] How to Unlock BootLoader for Canvas A177

I have a Micromax Canvas Juice A177.
Rooted successfully by FramaRoot.
I wanted to unlock the Bootloader but was unsuccessful in doing so.
Connected phone to pc and typed in adb
Code:
adb reboot-bootloader
So my phone rebooted into fastboot with a black screen and only "Fastboot mode.." on the screen.
i dont know what to do after that....
i tried
Code:
C:\android>fastboot oem unlock
...
FAILED (status read failed (Too many links))
finished. total time: 45.669s
As failed appeared i think it was not successful also i think that "fastboot oem unlock" only works for Nexus phones.
I need help. i want to unlock bootloader so that i can take a backup of my system.img etc directly on my pc.
Thanks in Advance.

[Q] Moto G stuck at "unlock..." screen

I was unlocking the bootloader. I entered the final command fastboot oem unlock UNIQUE_KEY and the device said Unlock...
It was supposed to reboot but it's stuck. It's not completely bricked coz after 10 min or so I entered
fastboot oem get_unlock_data and got this response:

OKAY [ 0.018s]

can you boot your device normally? you need to allow OEM unlocking under developer options before using the code.
Me too, I have the same problem, please help us!
