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?

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.

thanks for replay.

I tried to unlock the bootloader with adb commands but the console returns an error.

I remind you that the phone does not start.

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

Arrivo alla schermata nera, ma poi non entra in recovery, premo i tasti ma non va.

I get to the black screen, but then it doesn't go into recovery, I press the keys but it doesn't work.

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.
