dead on arrival, no more fastboot

Hi,
today I received my Mi A2. I unlocked developer options and enabled OEM unlock.
Then I rebooted to fastboot via power + vol down and executed
fastboot flashing unlock_critical
as fastboot oem unlock didn't work (command unknown).
I got the bootloader unlock screen and commited by "unlock bootloader" + power button.
Until then the phone booted up. However I wasn't able to boot TWRP-3.2.3-jasmine-20180804.img or a magisk patched_boot.img, both attempts just hung without progress.
Now I'm stuck at the android one logo and nothing happens or at fastboot logo with no device detected.
I suspect it's bad RAM.
anyone else?

fastboot doesn't work, it's stuck at "waiting for device" and fastboot devices shows a blank space, though I see the mi bot logo.
I'll return it.
for me every single attempt to flash a file failed though it showed the unlocked logo for the few times it booted.
it even showed random behaviour (fastboot returned unknown command, etc.), took several times for fastboot reboot or did nothing, it's defective.

Change port USB, remove driver's and begin cero.
Si entiendes algo de expañol, elimina los drivers del pc y comienza como si estuvieras comenzando desde cero, cambia de puerto USB y conecta con el teléfono en fastboot se debería de instalar el driver.
Prueba también a Agregar hardware heredado, y ya sea por puertos COM o por otros lados Android Bootloader Interface.
Como yo lo desbloqueé fue con fastboot oem unlock.
Le he dejado en peores condiciones en varias ocasiones no he visto manera de pasar al Sistema después de instalar TWRP, así que me ha tocado recuperarlo en bastantes ocasiones.

cannot even reach it under ubuntu via fastboot
it's impossible that I broke it cause I wasn't able to flash a kernel (boot.img) or something else
and I wasn't able to switch a slot: "this device doesn't support slots". when I entered fastboot set_active a it returned
this device only support slots
a
b
it acted as if it was infected with an ART rootkit or had bad memory.

In my case I was trying to flash MIUI 10 the third time then it fails I was using Android One rom September update and it was working flawlessly without any problem.
After miflash tool fails to flash my phone wont be detected either of my PC and Mac
I am thinking using deep flash cable to enter EDL but is it possible for MI A2 hopefully it is because I don't want my phone to be opened, ITS NEW :crying:
Am I still covered by warranty? If not I have to send my phone to repair shop to just enter EDL mode and to be able to flash stock or miui again
About me flashing MIUI I did follow instructions to avoid Anti Rollback (Never flashed MIUI 10 via twrp instead I flash custom roms)

Same thing happened with me no fastboot no edl .
Then I flashed my phone using test points method.
And yes you need to open your phone for that.

Then I guess I need to open mine too
Is it guaranteed that the phone will work again?
Have you tried it yourself?

Yes It will work 100%....Best of luck ..Open it very carefully..Must watch some videos in YouTube how to open Mi A2.

Does it work with deep-cable? Or another option before open it? I prefer return to Amazon than open...

Fix it?

Yo intenté todo eso, el problema es que ningún PC reconoce el Xiaomi mi A2 aún cuando está en modo fastboot, lo único que sale es esperando dispositivo, no más no lo reconoce.

Did anyone solved this problem?
I've bricked my device and I can get on fastboot mode but the PC won't recognize the device.
I've tried several computers and systems, windows, ubuntu, debian...
Did the deep flash USB cable work?

You have to flash an older Firmware. for this you need to boot in Download mode (Volume up and power Key while connecting to the PC) LG disabled the service of some Lg Q6 phones.

can't install from miflash

*you probably need to unlock flashing critical, there is a tool on the forum to do that, is a fastboot command.
*probablemente necesitas desbloquear el flashing critical (algo así), usa la herramienta del foro para hacerlo, es un comando de fastboot

I have the critical unlock and I can flash in edl mode, only on the fasboot give a error in flash, the error begin in moment I flash and say Bluetooth can't flash

Mi A2 Hard Bricked (Anti-Rollback on October update?)

Hello.
I was on the September update, unlocked and rooted, but I wanted to update to the october one, so I uninstalled magisk and flashed the september boot and system images.
Unfortunately that didn't work (I still couldn't install the OTA), so I' ve decided to flash manually all the images of the october update (I got them on the OTA thread).
After that my device went on bootloop, so I decided to flash again all the images of the September update (V9.6.13.0).
When I run "fastboot flash system_a system.img" I got the error "Invalid argument" and after that my device turned off.
Now IT IS TOTALLY BRICKED, I can't turn it on and I can't even enter fastboot.
I really don't know what to do, do you have any idea?

If you have working fastboot try to Flash full September update with Mi flash tools, wipe everything and Lock bootloader.
After that you will receive ota from October.

Open your phone and flash through EDL mode by shorting test points...

Yep, your last hope is attempt to flash through edl mode by shorting those pins, that's why I always re-install stock rom using Mi flash through edl mode booted from fastboot

Thanks guys, I hope to find a method which doesn't require to open the device.. if I fail I'll try the test points one.
However my device is still recognized by Windows and by MiFlash as Qualcomm QDLoader 9008 and I've read that some people managed to flash a fastboot rom in this mode (on the Mi A1).
Isn't this EDL mode already?
Looking at this guide it looks like the whole point of "test points" is to get the device recognized as QDLoader 9008, isn't it?

When phone is recognized as qualcomm it means it's bricked so it entered edl by itself, you can use mi flash to get back to september patch, then boot into fastboot and flash it again, then ota
EDIT: anti rollback is still not activated in october patch

Whoaa that's great! (well, obviously it isn't, but at least I don't have to open the phone)
Are you sure about the anti rollback? So am I safe flashing the September fastboot images?
Thank you very much, I really appreciate your help

Yes, all A2 firmwares got ARB set to 2, I'm on 9.6.15
also, I was on first october build 9.6.14 but I had modified vendor, so I flashed september patch then got the ota to 9.6.15 so I'm sure, there's no ARB yet

I can enter un fastboot mode but my PC doesn't recognized my device, Someone can help me?
I have all drivers installed but always the same issue.

Hi guys.. Thanks for this article!!!. It was very useful. I had my Mi A2 bricked, I was in QDLoader 9008 state, but I didn't need to disassemble the MI A2, I think as Lurensu my device was already in the QDLoader state. I reached this state trying to manually update to the November patch, then "fastboot" didn't flash the aboot_b image, yes sure; I didn't realize this until the reboot.
I had the error "Cannot receive hello packet" with fails trying to flash with MiFlash, but the solution finally, was to have pressed the Power button for various seconds then the device was again ready for flash, and finally this was flashed to the September patch. I had this image files from some tools for rooting and updating.
Thanks again!...

I'm pretty sure your problem is more simple than you think. Perhaps this is not the more adequate Thread, you need the windows drivers for Mi A2. This trouble is easily "googleable" :good:

Con la herramienta Mi Flash de Xiaomi lo puedes recuperar fácilmente, todo está en Google. En parte es tener el programa MiFlash y que te bajes una ROM OEM de este sitio, lo flashees y queda como nuevo; todo esto suponiendo que no tenga un daño peor, pero eso es raro

Bootloop Redmi 9 (lancelot)

Hello i have flash TWRP on my Redmi 9
and on my computer i have typed this command
"fastboot reboot fastboot"
for acces to the fastbootd mode
and now i have
REDMI
Powered By Android
black screen
and
Redmi
Powered By Android
and this loop
my english is very bad
bye

I have this problem too!!! could you fix it? it happened to me when I did this too

try to hard reset

I had the same problem after trying to flash the TWRP custom recovery on my Redmi 9 (lancelot).
In case that someone still needs to know, following was my solution:
I needed to flash back the stock firmware on my device with SP Flashtool. For that you of course need to download the firmware and take the scatter file of it. Then grab a custom Download Agent File and an authentication file from the web.
Also you need the MTK_bypass utility with the right payloads from the github website (Redmi 9 is MT6768, just take the master collection payload, it worked for me). You need that tool to disable the DAA und SLA protection on your Redmi 9. (Except you have access to an authorized Mi account of course, then you can just flash it with Mi Flash tool, but usually, one doesn't have that.) Follow the instruction on the web, there are detailed ways how to install the right drivers and run the bypass utility correctly.
In my case I had to format my device with the automatic flashing in SP Flashtool before the flashing worked, but that was it - my Redmi 9 is working fine again.

thank you for the input as it really cleared my head after i took a break at trying to get this thing out of a bootloop.
this does work, using sp flash tool but the device will auto detect through usb and you've gotta have the scatter file and firmware for the device. after using the brom utility don't restart the phone, you will reverse the process.

I had the same issue, I was not able to enter neither recovery mode nor fastboot mode. But you are able to enter EDL mode, the Emergency Download Mode - in my case at least. From there I was able to unbrick the phone. I was able to enter EDL mode without opening the phone and using test points. Turning the phone on and connecting it to the computer in the same second as the screen goes on let me enter for some seconds, it was enough to let me run the tool to bypass the DAA and SLA protection of the device. Then I was able to flash back the stock firmware with SP-Flashtool. In my case I needed to format the device before the flashing worked, but then it booted back up alive.
Just be aware you probably need to install the proper drivers first to bypass DAA and SLA protection with LibUSB.

I have the same problem, help
I already tried all the methods in this post, my phone cannot access fastboot or recovery mode, and when I connect it via usb it starts immediately
