Try unlocking other vivo smartphones, it may be similar to all at a time coz everyine from v9 are updated to funtouch os 9.0 this says a uniformity among all so try to see flashing of other vivo phones and follow the same among ur phone too.

if we flash our android into another vivo kernel.

I just unlocked the bootloader on vivo y85a（the china version v9 youth-pd1730）using https://forum.xda-developers.com/general/rooting-roms/how-to-unlock-bootloader-vivo-phones-t3686690
the key is that the prog mbn file:you can't use the file from the firmware.In chinese forum someone said that if you want to flash the firmware to the phone,you should use different prog_emmc_firehose_8953_ddr.mbn.Here is the different file:https://drive.google.com/file/d/1KeWMM22g8x-aTKhjqS-pmW1iY7z6ZAs4/view?usp=sharing

I'm using this guide to unlock the bootloader.But I found noting can do after unlocked the bootloader.
Vivo add some verify in boot and recovery partition.I tried to port a twrp for y85a and flash it to recovery partition,but it cannot boot.Only "fastboot boot"can boot the twrp,and all of the partitions are report error.

i need Twrp or any custom recovery for Vivo V5
(Vivo 1601).
Please Help.

hello guys ,
i tried every method for unlocking boot loader , finally i found one of the easiest method to unlock boot loader .
Step 1. Boot Vivo V9 in to edl mode
Step 2. Use Qualcomm ultimate tool for unlock boot loader ( Software is free but you have to pay for UMT dongle it will cost approximate 35$ to 45$ depends on your country )
Step 3 . After unlocking boot loader grab your os from your emmc using JTAG
Step 4 . Patch boot file with Magisk .
Step 5 . Copy Magisk patch file in to your device and boot the device .
( BBK electronics vivo official website does not have updated fun touch os file , please don't use any online file , Use your own emmc storage os file for patching magisk )

Is your device detected on Device Manager?

What sort of commands are you using? I mean bootloader unlock doesn't happen via flashing anything or typing commands from a power shell on this device. All you gotta do is sign up in-depth test then after reboot your bootloader will be unlocked. With power shell/cmd you can flash stuff and custom recovery like twrp.

I've done the in-depth test and it's on the Fastboot screen but when I type fastboot flashing unlock in a command window it just shows me the help text for fastboot, which doesn't show any command or option for either flashing or unlock, so how can I get it to work if those aren't valid commands?
fastboot devices shows my phone, so the device is recognised.
EDIT: I'm still on Android 9 A.15. I understand that there's no unlocked for Android 10 yet.
EDIT: Nevermind. I was using adb/fastboot from the link in this guide, which is v1.3 https://www.ytechb.com/how-to-root-realme-5i-and-unlock-bootloader/
After I updated to minimal v1.43 from here it worked https://androidmtk.com/download-minimal-adb-and-fastboot-tool

My problem was same. But i successfully downgrade to color os 6. I guess you can try it too.
Enable USB Debugging and Allow unlock boot loader option in USB debugging.
Connect your mobile with PC and use following Command.
adb reboot bootloader
fastbook flashing unlock
Check mobile for unlock option.

How did you downgraded to colour os 6?
I'm trying to root my realme 5i that i upgraded to 10.

So can someone plz help me with how can i unlock bootloader of my oppo f9 pro any help would be really appreciated a lot

If in phone's Android -> Settings -> Developer options the option "OEM unlock" is available then enable it and re-start phone afterwards.
On PC-side you also have to install Oppo F9 Pro MediaTek VCOM Driver

Thanks for replying,
I would like 2 tell that i have already installed all drivers for my phone and my phone is fully connected via adb to my pc plus the OEM unlock is available and is of no use(the OPPO official service themselves says that OPPO phones don,t have any bootloader) ,then it simply means the OEM unlock is useless ,and i have tried it a million times using that vol.up/down + power button (OR) by adb commands nothings works.
So since my phones doesn't have any fastboot mode then how can i even unlock bootloader plz help

Wondering - because you stated your phone doesn't have a bootloader what OPPO officials confirmed - why then you try to unlock phone's bootloader?
BTW: ADB commands operate on Android OS, not on phone's bootloader what in fact Fastboot commands do.
Example commands sequence:
Code:
adb devices
adb reboot fastboot
fastboot reboot fastboot 2>nul
adb get-state

ok bro i got my answer thx

Did you root your oppo f9?

I want to root my Nokia 1.4

How can I root my Nokia 1.4 Android 11(Go edition)

Unlock bootloader and flash magisk. Since the device is new, I recon that you will need to wait a couple of months for a guide to pop up. Or you could try your hand with generic guides on web and risk it. Either you unlock and root your device or you hard brick it. Nothing a trip to the service won't fix.

I unlocked bootloader

Bootloader

Can you tell me how to unlock bootloader please on Nokia 1.4 and root the device so that I can install twrp on it. I'm not a pro in these stuff

Just… go to dev options and enabwl oem unlocking then download platform tools on pc, boot into bootloader, and do an unlock command. Just find a generic, no-Samsung guide.
