Its because you don't have drivers installed properly.
I m using minimal abb and fastboot.
Install zuk usb drivers then enable usb debugging connect phone to usb.
Type in cmd
adb devices.
Give permission and tick allow always on prompt.
Then adb reboot bootloader.
Fastboot devices.
If u see your device proceed ahead otherwise install drivers properly.

if you have installed drivers properly, then this is happening due to permission issues ,
use this tool : drive.google.com/file/d/1WHHKKhs3pI4m9jNHhHmFL1fQeqtNS-3X/view
steps ;
1. click on run it will fix the permission issue (phone automatically boots to fastboot mode)
2. use fastboot provided in the tool to unlock, it should work ..
Its easy bro.mere saath bhi ho raha tha pehle ye batao ki aap computer se kar rahe ho ya laptop se .

Are you using the latest FASTBOOT.exe?
Can you screenshot the CMD?
unknown commands usually indicate an error in the command not the execution of the command.

Unfortunately I am at work and only have the C to C cable that was in the box.
My sdk/platform tools files are the same ones I've used with my 6P since 11-2015, and unlocking the 2 XL bl worked on the first attempt.
my process:

open cmd prompt in platform tools folder
fastboot devices (recognized my device)
fastboot flashing unlock
use vol up to select UNLOCK MY BOOTLOADER

I started off with what I was using with my pixel XL and that didn't work and I have installed about 10 different version thus far and still nothing
I basically ended up using another cable, different version of adb, and another computer. Hard to tell what the problem exactly was since I changed 3 things at the same time between it not working and working. My guess is the cable and/or the computer.

The easiest way is to flash vbmeta using this command "fastboot flash vbmeta vbmeta.img". This has to be done from PC of course.

maybe this helps, run fastboot, go to adb folder open command window type "fastboot devices" if your device ID shows up or not ,
if not reinstall adb drivers,
, also check your data cable

Solved without edl or other stuff lol
Hello guys:
One month ago i bought a Redmi note 8 pro, when it comes after a long time (almost 3 weeks) it comes with bootloader opened so i couldn use for example NFC pay. I looked for information to lock the bootloader i followed steps and bootloader was closed but phone was bricked too, so only can put smarthphone in fastboot or in recovery mode. I tried flash some roms by Fastboot using CMD in pc but appears this message
C:\adb>fastboot flash system system.img
target reported max download size of 134217728 bytes
erasing 'system'...
FAILED (remote: not allowed in locked state)
finished. total time: 0.004s
that was expected because bootloader is closed, but now i dont know if its posible to unlock bootloader and flash a new rom or beeing bootloader closed, flash a new rom for unbrick the phone.
To solve this problem I heard something abou autoriced xiaomi accounts and something about waiting seven days for unlock but i dont know nothing about it.
Thank you guys.

I have tried to flash with fastboot and with miflash pro, and it always fails, I imagine that the flash tool will do the same as miflash pro and it will also fail, I will try anyway.

I'm sorry for answering late, but I'm very busy with the current health situation.
What I have done is focus on unlocking the bootloader, and later will flash a new rom.
To unlock the device i have download "mi flash unlock tool"
Software recognice my phone
Click on "unlock">"unlock anyway">"unlock anyway"
Verifying device-ok
Unlocking-Fail
Couldn´t unlock
Please add your account in MIUI´s Settings > Developers option > Mi Unlock status
This way doesnt work.

And well...I dont know what to do now.
It won't unlock because your device is already unlocked. You need to flash stock rom from custom recovery. Install custom recovery via adb. when you go back to stock rom device will be oem locked again. Also original account that was used to oem unlock device may be required that is why it might be failing.
https://forum.xda-developers.com/re...de-unlock-bootloader-flash-twrp-root-t3995919 (useful software here)
After flashing stock rom In fastboot try
Linux: adb fastboot-linux oem lock
OSX: adb fastboot-mac oem lock
Windows: adb fastboot-windows.exe oem lock
I've tried to unlock my device with enable OEM unlock in the developer options, because it is needed for enable VoLTE in my regions(with QPST). But it seems that device doesn't recognize it's allowed to unlock. Every advanced fastboot command in fastboot mode returns "FAILED (remote: 'Command not supported in default implementation')".
Is this possible to you who using the device to unlock the bootloader with fastboot? Or, OTA updates I've received blocked that?
How unlock the bootloader?My HTC U20 5G no download mode in bootloader !!!!!
Try

Try rebooting to the bootloader screen instead of directly rebooting. This solved my problem.

Hi, Just manually enter the fast boot mode with power key+Volume Up or Down depending upon the model and make, You can search this online how to enter Bootloader mode for one particular device. Once you are in Bootloader, Try Fastboot mode and Enter your commands. Should work
Anyone figure this out on Nord n200 5g T-Mobile variant? Please help
