Hi!
maxresdefault-e1507640029694.jpg

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.

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
Downloadvivo_fastboot For Linux

Download : Vivo_fastboot_v2 :- Linux Windows
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.

If you are using linux then type

sudo ./fastboot bbk unlock_vivo

If you are using Windows then type

fastboot bbk unlock_vivo

Voila ! Your Vivo Phone is now Unlocked.

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.
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.

I discovered a new method few months ago, & it works well on new vivo devices:-
This method is unofficial & may brick your device (in 1% cases)
I'm not responsible for any loss or harm done to your device, sdcard, PC, home, ferrari etc.
If You are using this method to unlock bootloader, use at your own risk !

Downloads :-
BLUnlocker_v1.zip
QDLoader_HS_USB_Driver.7z
Steps to unlock bootloader :-

1. Extract the BLUnlocker_v1.zip (You have done this already, trust me, i know you did it :)
2. Install Qualcomm USB Driver for Qdloader 9008 mode.
3. Get your phone, press vol up & down buttons together & connect USB at the same time.
4. Extract your firehose file from your stock firmware (It's usually named like 'prog_emmc_firehose_****.mbn') & place it in the current directory.
5. Check the port number your device is connected to in WIndows Device Manager. (Looks like COM*)
6. Double Click the 'dump_devinfo.bat' file.
7. Enter the port number (from step 5) & press enter
8. Edit your devinfo.img using HxD Hex Editor as shown in my video (Or you can comment on my channel with a link to your devinfo.img)
9. Double click 'unlock.bat'

I was able to get the full firmware (11gb) of vivo x50 pro (that's as X51 5G is labelled in some markets).
But on it there is only a firehose with .elf extension.
Unfortunately in the video we are talking about a firehose .mbn

Tried this on Vivo Y1s (2015), bootloader "k65v1_64_bsp-3461ff4-20210119145118-202". Using v2 with "fastboot vivo_bsp unlock_vivo" doesn't work - locks up on "waiting for device" on windows, the original goes "remote: unknown command". Using FTOS 10.5 build PD2014F_EX_A_1.12.17, regional link to Russia. Security patch as of 01.01.2021.
Did anyone have luck recently? Apparently this indian guy did, on android 11:
