by mistake I lock my bootloader with miflash. Ok, no problem, just unlocked again... nope.
Everytime I go to unlocked, miunlock give me an error: couldn't unlock and some chineses words.
I tried everything, account related, changing PC and USB port and cable, OEM unlock on and off, my phone is bound to account and shows on Mi Cloud, debug on and off, log of and login with mi account, reset the phone and flash again global dev with miflash... nothing work.
I'm out of ideas... any help?

I want to unlock bootloader of my Mi Max 3. Already follow the procedure to unlock. Login to Mi Account in Mi Unlock Tool. My phone is in fastboot mode. When I connect the phone to PC, the fastboot mode on the phone suddenly disappear. On the top left of the phone screen there is a message "Tap any key to reboot". I try few times, the problem still assist. How to solve this
try a different USB port on your computer.
Try other USB drive, still the problem still there. Should I reset my phone?

It would be easier to enable USB debug, get the unlock program started and phone connected, and use adb command to reboot to fastboot mode:
> adb reboot bootloader
I've been following the steps to unlock my bootloader, and after inputting the "fastboot flash unlock unlock.bin", the command prompt froze for a good 5 minutes. After googling a video of someone doing the same thing, I saw they got an output almost instantly, so I cancelled the operation (through ctrl c), and restarted the phone.
Since then, the phone's pop up for authorizing USB debugging never came up, I've switched the protocols, tried different PCs and even factory reset the phone, but the problem is still happening.
Does anyone know how this could be fixed, if it can at all?
Thanks in advance.
Update #2: I've been able to connect the A2 to my PC and can detect it when in fastboot mode with the "adb/fastboot" tools and with the MiFlash utility. I attempted to flash an earlier version of a ROM but I can't. MiFlash gives:
"Erase boot_a error"
I then attempted to unlock the device with the "Mi Unlock" tool but get "Sorry, your MI ID is not associated with a phone number"
Any suggestions on how to unlock the bootloader?
Update: After waiting a few minutes the touch screen started responding for a few inputs, and then stops. Toggling the lock screen a few times allows additional inputs for a few presses.
A couple of months ago the phone started displaying issues with touch input. Locking and unlocking the screen would correct the issue for a while. However, as time progressed the issue got worse.
Today I did a factory reset and since then I have been unable to input any operations. The phone is stuck on the "Hi there" welcome screen and I cannot press "Start". Power and volume buttons work fine, so I attempted to use "adb" to flash a new ROM, or a stock ROM from before July/August.
My PC won't detect the phone when in "fastboot"
What options are left?
Can I dump the stock ROM to an SD-Card and attempt to flash that from the bootloader?
Or do I need to unlock the phone prior to any ROM manipulation?
thanks for any advice

Boot your phone in system (normally).
Find build number in settings, about phone. Tap 7 times or until you've unlock developer options.
Turn on OEM Unlock and USB Debugging.
Turn off phone and boot fastboot mode.
Type 'fastboot oem unlock' and wait until it finish wipe phone.
And it's done.

Thanks, that worked. I am now able to flash an earlier ROM, will see if that fixes the screen input issue.
Flashed an earlier version of the ROM and still had issues, so I finally managed to flash an alternative ROM - HavocOS - and that experienced the issue as well. Looks like the phone has a hardware issue somewhere.
i cant unlock my mi 6 phone. When I plug it into the computer, there is a sound, it shows up in the device manager. I open the unlock tool, the device shows up but the unlock button does not appear. It says verifying device information, then it gives a failed error. I unlocked it before but then I locked it. thanks.

Hi, I wanna flash a boot.img on my Mi Pad 5 with a locked bootloader.
I tried everything to get into brom mode, didn't work.
Please help.
First of all, you can't flash images with a locked bootloader. Second, this device has a Qualcomm processor, so there's no brom mode (which is found on MediaTek devices), you'll need to unlock the bootloader.
