Please Master help me. I want to root my phone but first, i have to unlock bootloader from this phone (Vivo V20). I already use Command Line " fastboot flashing unlock ", " fastboot oem unlock ", " fastboot bbk unlock_vivo ", "fastboot bbk vivo_bsp unlock_vivo". Nothing Works...
Maybe someone here know how to see command line to unlock bootloader manually from system file, please help.

1. You need to Enable developer mode on your phone
2. You need to enable USB Debugging inside of developer options
3. Also, enable OEM Unlock inside developer options also ( If you dont see this option, good luck with rooting.. )
You will also need to set up ADB platform tools sdk on your computer if you are going to root
SDK Tools Setup - https://www.xda-developers.com/install-adb-windows-macos-linux/
Unlock Bootloader - https://www.lifewire.com/how-to-unlock-bootloader-android-phone-4689186
Be carefull please Dont brick your device... make sure to do your research and verify that your specific phone can be rooted...

Vivo doesn't allow their devices' bootloader getting unlocked, so you can't unlock (most of) them.
On their support page, they stated "BL cannot be unlocked" (which is false), and "suggest you not to try it".

If you really want to unlock your bootloader, nah you can't, the only way might be selling your Vivo for something else (OnePlus, Xiaomi, etc.) that allows bootloader unlocking.

Edit 1: For some older Vivo (and Oppo), you might be able to use EDL to flash a custom recovery. OR for even older ones, you can actually unlock.

Edit 2: I believe most Vivo (including Oppo) doesn't even have the normal aboot bootloader mode.

Can those 3 varieties of phones you listed be rooted even if its a US Version phone?
