[HELP] I cant re-unlock the bootloader [A2]

Hi, today i tried to install MIUI 10 following this video: https://www.youtube.com/watch?v=eD5ftq6lTKo
When i could installed it, i tried to re-lock the bootloader with this other video: https://www.youtube.com/watch?v=9C47rmEKkys
But when i reboot the phone, on screen was this message: The system is destroyed, press power button to shutdown.
I tried to unlock again the bootloader to install the system but i receive this message from cmd: FAILED (remote: Token Verify Failed, Reboot the device
)
I don´t know what to do, i tried with test points to flash with miflash, i tried with miflash unlock but i don´t have an account of xiaomi.
when i use this command: fastboot flashing unlock_critical i receive this message: Command not support: the display is not enabled'
Somebody help me :crying:

Flash stock ROM with mi flash

I tried that but miflash show this message: Mismatching image and device. Only have a success message when i flash the wayne rom but ends on 1 second but doesn't install the system.
On htcmania says because the drivers are wrong but i reinstalled from the tutorial ones, google drivers, and miflash drivers and always says the same.
Now i trying with EMMC dongle program(cracked) and it seems like it´s installing the system, but since yesterday, it looks last forever.

Well that program does not did anything, i discover that when the phone is on fastboot mode and plug off the battery, miflash make a process success but it last 24s and don´t do anything, maybe that could be useful for something.
I don´t know what more to do with my phone.

If ur bootloader is unlocked try
Fastboot reboot edl
Now try to flash with mi flash in this mode
Note: your phone will look like it's turned off (black screen) in this mode
---------- Post added at 02:35 AM ---------- Previous post was at 02:29 AM ----------
I noticed that you where trying to flash Wayne images in the photo that u attached? Do u own a mi A2 or a 6x?
If you convert your mi A2 to 6x you cannot relock your bootloader
And make sure to delete system update folder and change some Dev conf file to flash miui on your android one device

That command (Fastboot reboot edl) doesn't work, when i send it i get this error: Device is already locked!
The only way my phone can be on edl mode is by Test points, and the miflash says that my phone have a locked bootloader if i try to flash the system.

What is the output of this command
Fastboot oem unlock

Fastboot isnt working..?

Hey guys
I just bought a new Mi 9 Lite and instantanously wanted to unlock it.
so i did all the steps and then tried to connect with mi unlock the first time to see how long the waiting period is
After i booted into fastboot with volume down + power i connected the phone to the computer and it suddenly went black.
Only in the upper corner it showed a cut off text saying: "any key to shut down" -> see attached photo

Mi Unlock didnt detect it, and neither did Adb fastboot...
Do you know a fix? i really dont want to send it back...
And im pretty certain this was not my mistake, as i tried it multiple times

Same happens when you try to boot into fastboot with "adb reboot bootloader" ?
BTW to see if your device is properly recognized while you are in Fastboot you should use "Fastboot devices" not "adb devices"
Also make sure you installed all required drivers (Qualcomm ones and the drivers you install from within MiFlash)

the reason is windows 10, on 7 it works

Thanks for your fast answer!
I just tried it again, and adb as well as fastboot devices do recognize the phone.
The blackscreen from fastboot only appears upon opening the mi flash unlock tool... In the exact same moment...
As you said i tried "adb reboot bootloader", but the same happened upon opening the tool.
I couldnt find the qualcomm ones though, didnt know where to install them from...
Btw. if it helps i have Windows 8.1
But havent had Problems with the Mi9 or Redmi 4 Prime unlock (which just now worked fine)

Installed it, and even re-installed all the usual drivers. Still, the black screen pops up as soon as i open the unlock tool...

Check if your phone isn't fake one.
This is unusual for an official Xiaomi device.

How would i check?
Also its not from china, but from a well known german vendor so guarantee would be no problem. But everything is fine and believable, so i would have no reason to be suspicious.
I guess i will try with another computer next week or something. Maybe its USB 2.0 or something..
At least thats what that thread suggests: https://forum.xda-developers.com/redmi-note-5-pro/help/help-press-key-to-shutdown-fastboot-t3816021
Thanks for your suggestions!!!

Is your phone recognized in device manager when you are in fastboot?
Also i heard there is some bug/incompatibility with Ryzen CPU's, do you have Ryzen or Intel?

Indeed it is recognizes in adb as well as in fastboot.
It's an old Thinkpad im working on, so its an Intel. I still only have simple Usb-ports.
But im surprised as it has worked with the Mi 9 also a few weeks ago...

Yet another unlock bootloader question

I have a Nokia 8 model TA-1052 (this is NB1, correct?). It has a locked bootloader and is running Android 9.
I understand the HMD service for unlocking the booloader is no longer available and the only option now is using a Hikari's website.
Before I try Hikari's method I want to make sure that fastboot is working (I understand it is required?).
With the phone connected, the command "adb devices" show the phone listed but any fastboot command seems to not being able to find the phone (e.g. "fastboot devices" returns nothing).
Am I missing anything?
Thank you.

Assuming you are on Windows what does device manager show when you put the phone into fastboot mode?
Obviously you need a working driver for fastboot mode which is separate from the adb driver - how did you install the drivers and which ones did you use?

I don't have any specific Nokia drivers installed. The only USB driver showing (that seem to be related) is "ADB Interface".
I know that for some people the Nokia driver comes on the phone but mine isn't. Where can I get the driver from?
EDIT: in download mode the Win10 Device Manager shows an unknown "Android" device under other devices

i just unlocked my phone with this tool and somehow it's back to android 8.1 oreo, is that the normal behavior?

Hi, i used the methode in the link above but now my phone is stuck on the Nokia logo and won't boot to OS.
I can let the batterij drain and power it on but then i get this message in the picture.
Manually getting it into download mode is impossible (holding combo keys volume down and power looks like that doesn't work)

Some idea how to fix this? Luckely its not my daily driver but a testdevice.

I have it working again, let battery fully drain, then i could get into download mode (holding vol- while plugging usb) then I could run the tool again (had to request new OTP) and now it just boot normally

if you have deleted the cow partitions you can flash the payload.bin via fastbootd (the payload.bin can easily be flashed with FastbootEnhance via fastbootd)

People really need to stop trying to flash with fastboot. You should have used Fastboot Enhance. It's pretty straightforward and if you accidentally cleared one partition you shouldn't have in FBE (it's kind of hard to tell with your English if you did or not, sorry), you could have tried to flash just that one partition with fastboot instead of using a script. OnePlus is your only hope now.

Will it go back into to fastboot...?
If you can try and set slot to A . if you get back to fastboot do this
" fastboot getvar current-slot " it should tell you what slot you on...A or B
if you on B then use this to set A active . Use this command to set A active
" fastboot set_active other " or " fastboot set_active a "

If you can't get to EDL or otherwise then it'll most likely be a swap or a board change.
Unless they have a lower level flash which I'm not aware of.
None of this can be done remotely.

You can take the back off ...Ground out test points if your up to that...or send back save yourself the head ache .

Can't unlock bootloader on redmi 9 [SOLVED]

I've already searched for it and can't find anything. The closest I've got is to installing the USB driver. I opened driver_install.exe and still can't find the driver in Device Manager. I have OEM unlocking and USB debugging on. I also have my MI account linked and the unlock folder in C:\.

Cant unlock bootloader with several versionsofunlock tools.
Latest tool v2 alpha builds recognizes phone when it is started mi ui. Then it reboot phone to fastboot , windows gling glang sound and then tool shows no phone connected. Tried wuth 2 cables. Checked devicemanager- when mi note 9 in fastboot it appears as android with esclamation mark.
Tried to reinstall adb drivers and also usb qualcom. Same.
In windows or in ubuntu note 9 is always recognizes and can accesss its internal storage.

Use the official tool and install the drivers (remove the drivers previously installed before and restart).

Tried version in link- same situation.
Looks like problem is that windows is loosing connection when phone goes in Fastboot.
This is how device manager looks like when phone in fastboot

Tried to turn off signature verification, but then bittlocker started to behave strange at boot up/couldnt enter code - 8 numbers.
Then tried to reinstall one of 4 ubuntu laptops. There got boot failure, prepared usb with another tool, then got another boot failure.
Maybe there are tools for Linux to do bootloader unlock?

I had the case with an Intel W10 PC, as soon as I launched Miunlock the device disappeared, I tried all without success but with an Amd W10 PC, no problem (sometimes it's the opposite).
There are other ways to unlock the bootloader but I don't recommend them (do a search), too risky, anyway if you have a driver problem it won't change anything.
