You are already be advised to have your bootloader always unlocked just in case, or at least have oem unlock option turned on. But if you get into that situation, here's some method of fixing that,
Try forcing reboot by pressing and holding the power button until it reboot,try to see if that is fixed.
If not, try holding volume up and power button at the same time to see if you get into the recovery, if it does, it shows says no command, press the power button once and get into a menu, do a factory reset.
If not either boot into fastboot mode, change to the opposite slot (a to b or b to a) if it allows you to do that.

Boot into EDL using short points and then flash
The only way to fix a bricked xiaomi with a locked bootloader is to manually boot into EDL using short points and flash from there. It's super easy but you will void the warranty since you have to open the phone. I have a Mi A2 that was stuck on Android One logo and my bootloader was locked. I flashed it and now it works.

Did you face same problem!
I took it to a service center. The person there tried this method.but he couldn't do it.Rather he bricked my phone totally.Later flashed the patched rom again.Also he removed imei number.now imei shows 0000000000 but i can use the phone. There is no problem with network. Testpoint method is supposed to work but flashing gets stuck at 50-60% every time.
im also stuck on miui with locked bootloader. You can't flash a2 rom beacuse u have enabled arb 4. I was looking for a solution but didnt find so far

Tried to convert and locked bootloader while no system installed accidently.
The trick in my case was to press power button while pressing flash. Otherweise it would fail
Try different USB Ports too

Xiaomi Mi A2 (m1804d2sg) bricked

I just received this smartphone from a friend of mine.
The smartphone is locked on the "androidone" logo.
In the past I fiddled with different andorid devices but with xiaomi I am really puzzled, I don't know how to move.
I tried to enter recovery mode, pressing "vol +" and "power" without a positive result.
I can get into fastboot mode and try to flash the rom with miflasher but I get an error: can not file all.bat.
How can I solve it?
Is your bootloader unlocked?
first unlock bootloader (critical too) then try to flash original stock rom with miflash. Dont try to downgrade android version idk you know it or not but A2 has antiroolback projection which if you downgrade your android version (ex: 9.0 to 8.0) device will delete your phones IMEI code. And the only way of fix that is change main board.

You must boot to phone and check oem Unlocking at developer options first. You said u can't enter recovery, at mi a2 is little bit tricky, you keep power and volume + buttons until restart and enters a black screen and after u push 1 time (without keeping buttons) power and volume + button again and it enters at recovery

I have seen many videos on youtube and I realize that the system is compromised.
Recovery mode is impossible to start. Following all the steps I get only a black screen and the recovery does not start.
My question is: Can't I install the firmware via fastboot?
I saw some videos showing a jumper to send the phone to QUALCOMM mode.
Can I flash in this mode having the bootloader blocked?

I can't enter to TWRP recovery u right there is a problem with some Mi A2 devices.
Qualcomm mode is EDL (Qualcomm emergency downloader) and no u can't install firmware or any other thing with bootloader locked. I have googled the enabling oem unlock via fastboot but thats too hard and complicated thing u need to know a lot of things about Android system files, fastboot and .java files to enable it if there is a someone can try to find how to do it and give us a tutorial about that that will be great because thats important thing cuz we can get boot loop with system updates .
Here is the screenshot of the enabling oem unlock via fastboot

I haven't try this but I think you can do that. There are many persons here at forum that they have used this. Search them threads before u start to see exactly how you do this (I think it is time limited the edl mode via jumper)
Here is a similar situation, read the last messages, there is also a video tutorial.

Mi9 Global - Accidentally locked bootloader and stock in recovery/fastboot

Hi,
Recently purchased a Mi 9 Global version, got the OTA update to MIUI 11, and everything was well. It is a superb phone, but I like to have root on my phones (mostly for Adblocking and System2, better control overall). I tried to install TWRP (custom version for Mi9) because I wanted to install Magisk/Root or try a different rom eventually. Anyway... I made a huge mistake. After trying to reboot, I noticed things had gone wrong, and was stuck in a boot loop. I guess I panicked and tried to flash the phone back to the latest global MIUI rom (Version 11, Android 10, from official site), using the Xiaomi Flash App but I did not uncheck the "clean and lock bootloader" checkbox on the bottom right of the app, which is somehow enabled by default. The flash failed at that time, for unknown reason, but it seems like it succeeded in locking my bootloader, with an empty partition, except for fastboot access and Mi Recovery module. I have to admit I've always been pretty lucky with all my previous flashes on other devices, and I guess I got a little careless. That was pretty stupid of me, in retrospect.
Since then, I am stuck in either Mi Recovery or Fastboot, and it seems that my originally Global Mi 9 with unlock bootloader has now a locked bootloader. Any attempt at either using the Xiaomi Flash utility gives me an error message ("Erase boot error"), and if I boot into Fastboot and try to flash TWRP, I get the "Remote:Erase is not allowed in Lock State" error.
From what I understand, my options are pretty limited now. The phone is still powered on, stuck in Recovery mode and rebooting every 5 or 10 minutes by itself (probably a way to avoid screen burn-in?), but I can't seem to be able to shut it down in anyway, as there are no fastboot commands to send a shutdown signal. And no matter what button combination I press, the phone always ends up rebooting.
I tried the Xiaomi Unlocker utility, but it needs the phone to be out of recovery to check the credentials binding the phone to my account. All data on the phone has been wiped already, so that's not an option. Two options I have seen :
1. Open the battery cover (required a heat gun and risky), to short some pins and try to flash while there is a short to circumvent the security. I'm not that brave yet, and since the phone is still running and has probably about 80% battery, I don't want to use a heat gun on the device.
2. Shady stuff involving paying 30 or 40 Euros to a random guy who can somehow make everything work magically by remotely logging in on my computer via Teamviewer (Not happening in a million years).
I'm wondering if there is an alternative, other than bringing the device to an official Xiaomi store (I'm in Bangkok and they do have one official shop at Fortune Town), but even then, I don't know if they'll just tell me I got myself an expensive paperweight.
Any help/insight regarding this issue would be much, much appreciated!
Have you tried to press and hold power+vol down when your device reboots? Just before it turns on.

Every possible combination on reboot will either bring me to Fastboot or Mi Recovery. I have wiped the data partition, there is no OS on the phone as of now.

Xiaomitool V2 is completely useless. The "My phone is bricked" option is not implemented, and I cannot boot into the OS, unfortunately.
To enter fastboot mode, long press the volume down key and the power key. Then unlock bootloader with Xiaomi app.

Yep, but it has unlock option in the normal mode and it use scripts made by tool developer, so it worth to try.

From what I understand, the "normal mode" needs the tool to be able to access the OS while it's running. I don't have an OS. I will give it a shot tomorrow (3 AM here, exhausted, and don't want to boot into Windows again!), but my hopes are not so high. Anyway, thanks for the help, much appreciated! Will let you know what happens! Cheers!

Unfortunately, this is not true. I have downloaded an old version of Mi Unlock (2.2.406.5), which is supposed to work with Fastboot mode. The result is "Couldn't unlock --> Please download the latest version". And the latest version needs to access the OS to verify the Mi account credentials. I don't have an OS installed. So this won't work. Thanks for the suggestion though!

That's honestly one of the most useless answers I've read here.
To even be able to unlock the bootloader, you HAVE TO enter the fastboot mode and he cannot. So what you'r saying doesn't make any sense. Like at all.
I do have the same btw and I'm running out of ideas, so if anyone actually has something helpful to say I'd be very thankful.
Neither the button combo nor the adb reboot bootloader does work. I can see the fastboot screen for like half a second and then it reboots normally without even touching the device.
Edit: I just found a way to enter fastboot on my realme X2 Pro.
You have to click on "Start in depth test" on the official Realme App, which can be found here: https://c.realme.com/in/post-detail...64863306907648&subForumId=1197159778845982720

No, and before relocking bootloader, if your not "completely stock", you can brick your device.

I did install the testing app and i'm still having that issue where i only see the fastboot for a split second before the device reboots itself. What am i doing wrong? I also enabled developer mode - OEM unlock - USB debug.
I've flashed my device before and i've even been able to unbrick my own device after "destroying" boot image, but this is something new and it's coming from Realme and i don't appreciate it!
I'm actually looking to replace my device with something more flash friendly, what would you recommend as a good budget device to De-Googlefy?
Hey guys..I am facing the same issue. I cannot get into Fastboot mode using the key combination or adb method. With the ADB method and the unlock tool the phone reboots with fastboot written with some chinese characters for a split second and then boots up as normal.
Has anyone found any solutions?
I am on the 5th March 2021 security update.
I also suffer from the same problem, When I want to go to Fastboot, a logo comes for 2/3 seconds and then the system is rebooted.
I am also facing the same issue. Any Help?

Mi A2 bootloop even after flashing

Hi everyone
I'm having this weird situation:
Bootloader is locked, can't OEM unlock or execute flashing_critical command.
I tried flashing a couple of stock ROMs through EDL mode and MiFlash but all I find when powering the phone is just an Android One logo that just doesn't boot.
The only different thing I've found so far is when flashing 10.0.13.0, the phone shuts down after Android logo and If I keep reseting it this way by keeping power button pressed, a menu appears saying that boot failed and giving me two options: retry or power off (also tried leaving it on that menu while charging as people suggested but when retrying it just bootloops as well)
I would really appreciate some help with this...
