Okay, so it looks as if Fastboot is disabled on my device. I went into the Stock Rom, and I found there is a switch on the Stock Rom that turns Fastboot on and off. It says: Allow Oem Unlock.
I've heard of some folks bricking their Phones this way by flipping this switch in the stock rom. Is that true?
My choices seem to be:
1. Use SP Flash Tool to Flash TWRP. Then TWRP to load AOSP Extanded, or Lineage.
2. attempt to use that switch to see if it will let me do a fastboot oem unlock.
I'd like to try the second, but I want to know if thats a land mine to a bricked Phone if I flip the switch to allow OEM Unlock of the bootloader.
$ fastboot-android oem get_identifier_token
...
FAILED (remote: unknown command)
All attempts to use fastboot to unlock the device have met with this error.
It will fastboot reboot, but nothing else. I have a feeling something like the fastboot DirtyCow Exploit will be needed.
Hi!
What happens if you don't have permission to unlock bootloader and you still try to do it using fastboot oem unlock on Xiaomi Phones?
I have already got the permission and I've rooted my phone, so I didn't really try it because I was simply afraid. Has anybody tested that?
Also, if I relock my bootloader again using fastboot oem lock, will I be able to unlock it using fastboot oem unlock or will I have to use MI tool?
Aaaand the last question - I haven't installed custom rom or TWRP - I booted TWRP using fastboot boot xxx.img, then installed SuperSU package. Is it dangerous to lock bootloader with phone rooted? Recovery is still stock, so ....
Hello!
Today i was trying to return to factory conditions on my mido (recovery, ROM, bootloader, etc) but i locked the bootloader with "fastboot oem lock" instead of doing it with miunlock.
Now i am unable to flash anything, from fastboot roms, to custom recoveries, to anything.
Is there any way i can try and revive my device? I tried using miflash, unlocking again with miunlock, all to no avail.
Thanks in advance,
Carlo
Try this
Boot into bootloader and then connect to pc install mi flash tool and then after downloading rom click on clean and lock
Solved by using miunlock version at this link http<colon><slash><slash>en<dot>miui<dot>com<slash>forum<dot>php?mod=redirect&goto=findpost&ptid=204866&pid=
I unlocked the bootloader succesfully (amazingly!), flashed the fastboot rom with miflash and phone revived!
Hope this can be helpful to people with my same problem!
Hey I am trying to flash a custom recovery in order to install a new ROM but I can`t unlock the bootloader.I tried using fastboot oem unlock and fastboot flashing unlocking but the bootloader remain locked
Hi, so several months ago i installed MIUI 12 weekly to my Xiaomi Mi A3, and now I wanted to upgrade to the stable release. When i was flashing a boot image file, after restart, my twrp dissapear. I tried to flash the rom using Mi Flash on PC, but i touched the cable and the phone disconnected, locking the bootloader in the process. I have no OS, my bootloader is locked. Is my phone truly dead?
I also forgot to uninstall Magisk root from my phone, so it's my full mistake. adb doesn't recognize my phone. I can only turn on the phone, leave it on boot until the battery drains, or the fastboot. Is there any chances that I can save my phone?

I can't. It says i cannot flash while in Lock State. Basically i can't do anything without unlocked bootloader.
well unlock it, you have 2 comands to put.
fastboot flashing unlock
fastboot flashing unlock_critical
FAILED (remote: Token Verify Failed, Reboot the device) after i used the commands you told me.
What should I do next?
And Mi Unlock tool can't unlock the device, because I need to change some settings in Developer Options, and I have no rom.
did you try switching slots?
fastboot getvar current-slot
Getvar Variable not found
f###,
then only some recovery option with
mi tools.
Download mi a3 platform tool file then download fastboot and fastboot unlock critical file paste these both in platform tool folder then plug device through fastboot to pc then first click on fastboot unlock and then fastboot unlocking critical it will be unlocked then install the rom through mi flash
