Lately, after using this separate phone(Vivo V7+) for 2 years, I've been trying to root it.
The basic drill I found to root this phone is,
- Unlock bootloader
- Install TWRP
- Root it using Magisk/SuperSU

I've tried most of the methods mentioned online to unlock the bootloader,
While trying to unlock it using vivo fastboot, An error occurs.

Command: fastboot bbk unlock_vivo
Result: FAILED (remote: unlock fail.)

Another command: fastboot oem unlock
Result: FAILED (remote: unknown command or device is lock)

When rebooting device into fastboot using: adb reboot-bootloader the developer option, oem unlock & usb debugging all was turned all.

Much help appreciated, Thank You.

I have same issue to unlock the bootloader for vivo
I typed the methods, and it's not working
People said for new phones use this command: fastboot bbk vivo_bsp unlock_vivo
But I tried that to my new vivo phone and it's not working also
I'm thinking that people who failed need unlocking bootloader tools or download firmware of the vivo and remove bootloader (Make sure the stock firmware must have higher version, and your phone not updated)
Note: people have to downgrade to low version of vivo if they want the cmd method(if still not working)
