Hi!
vivo_bootloader_unlock
I’ve seen a lot of users struggling around the internet to find out the way to root vivo phones.
And, Yeah, There are a lot of tutorials available explaining how to unlock bootloader and root vivo phones, but , nearly all of them do not work.

So, After a bit of research, here’s what I got :-

Vivo developers modified there bootloader to used a different command for bootloader unlock/relock than the the stock android commands.

Also, On some phones like vivo y51l (Upgrade to PDF1510_2.6.7), you'll need to upgrade to the latest version available.

And That’s Why we need a modified fastboot binary to unlock bootloader of vivo.
vivo_fastboot on Github
WARNING! It’ll void your warranty.

Follow the below steps to unlock bootloader of vivo phones :-
I've compiled fastboot binary with necessary modifications which you can download from below

Download vivo_fastboot For Windows
Download : Vivo_fastboot_v2 :- Linux Windows

Download vivo_fastboot For Linux

Extract the downloaded files on your Computer and open Terminal/Command Prompt in the extracted directory

Now power off your vivo phone and enter fastboot mode by pressing power+ vol – buttons simultaneously.

vivo_lock

If you are using linux then type

sudo ./fastboot bbk unlock_vivo

ubuntu_vivo_unlock

If you are using Windows then type

fastboot bbk unlock_vivo

Voila ! Your Vivo Phone is now Unlocked.

vivo_unlock

If You Want to lock it again then just type

fastboot bbk lock_vivo

In case Of linux type

sudo ./fastboot bbk lock_vivo

UPDATE :- I discovered a new command for some Vivo phones, it isn't working for me but many user asked to make a fastboot binary with that command. Thanks @DjKinGinfo for asking me.
The new command is fastboot vivo_bsp unlock_vivo (Type fastboot help to get list of supported commands.) If this method isn't working for you, don't worry, I have another working method ( posting soon...)

Now you can port and flash twrp recovery and Custom Roms on your vivo devices.

Download the modified fastboot instead of using an official version.
For windows : https://drive.google.com/open?id=0Bw...GRRYTJkWXAzcUU

For linux : https://drive.google.com/open?id=0Bw...0VKd3JKai1oQnM

It seems like you have already installed fastboot systemwide.
To use the fastboot binary in current directory
Use this command : .\fastboot bbk unlock_vivo
Or just use command prompt instead of powershell on windows.

It looks like something is wrong with the bootloader or the firmware version installed in your phone is not supported (unlocking) yet.
As mentioned in the post some phones need to be upgraded (like vivo y51l).
If you have time and patience, try using different software version from vivoglobal or just reflash the current one.
Is oem unlock enabled from developer options ?
