How To Unlock Bootloader Of Vivo Phones ?

[ssanjeet]

My vivo y11 2019 refuses to unlock bootloader due to this command

C:\Users\Jun Evergreen\Desktop\vivo_fastboot_for_windows>fastboot bbk unlock_vivo
...
FAILED (remote: unclock fail.)
finished. total time: 0.002s

Did you try other methods for Vivo Y11? Worked or still stuck on it? Apparently, I also have Vivo y11 2019 so want to know if you were able to do it

Hi!

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'

If all went good, your bootloader is unlocked now!
Thanks me later, go break some eggs !
Peace !

fastboot oem enable_camera_hal3 true
why this command not working for camera2api?

 

[Chupool_Rodel]

everything went according to plan but the dumped devinfo.img is empty?? the complete file is only zeros??

Is this working also for Mediatek?

Hi All!,

Is there an update on how to unlock bootloader of Vivo Y30 2019. I still get the unknown command bbk. I need to root my phone to recover all my deleted files due to accidental reformat/reset.
I need to recover all my important files.


Thanks everyone.

Unlocking bootloader/ rebooting in edl without testpoint Vivo Y31 2021

Unlocked models with this method: Vivo Y31 PD2050F 2021 A12 6.7.20 Vivo V21e PD2107F A12 6.6.19 I did it from rooted Samsung J120F, I didn't try from PC///bc no PC =( My guide in Russian {Mod edit: Link removed} Custom fastboot for vivo in...

forum.xda-developers.com

 

[Pervokur]

new vivo model unlocked with my guide - vivo v21e PD2107F A12 6.6.19

the key of success
1. fastboot flash xxxx yyyy.img
should start uploading, error shouldn't be immediately
2. fastboot vivo_bsp unlock_vivo
should return "failed check Signature fail"

Person with v21e used another rooted phone like me, but you can try my two terminals attack from pc (windows, linux, linux in wsl windows, etc)

Managed to unlock my Vivo x70 Pro Plus thanks to you two guys.

Any idea how to figure out the "fastboot boot" command for vivo?
Right now its "FAILED (remote: unknown command)", would be great to boot into TWRP to backup.

I decompiled abl.elf and there is no such command
no boot, no fetch

Actually you can flash any recovery and reboot immediately into it.
After 1st normal boot it will be patched to stock recovery by install-recovery.sh from /vendor/bin

There seems to be some kind of other check as well though. Flashing a combination of FunTouch Firmware actually converts the recovery to english but flashing any kind of other image (ported TWRP to lahaina) ends up in endless loading. Not enough knowledge here to figure anything out sorry.
