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 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'

Hi, how to root Vivo Y83 Pro and change the recovery to TWRP?
I tried unlocking the OEM in the developer option and run the fastboot file in the terminal(PowerShell), but that is not working.
Is this method working? is there any chance to root the device?
Thanks

how to enter fastboot mode with a vivo air lte?
by pressing power+ vol – buttons you only enter the test menu "essential test, pcba test, test report...etc"
when entering recovery menu via power+ vol + there is also no option to enter fastboot..
if i use adb reboot-bootloader, the phone hangs in the white boot screen after it reboots.

    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.

    Follow the below steps to unlock bootloader of vivo phones :-

    If You Want to lock it again then just type

    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.
