[MI A2] Stuck at Bootloop

I tried to flash Miui 9 on my Mi A2 with this install guide (https://forum.xda-developers.com/mi-a2/how-to/miui-10-install-guide-t3844729). But when i flashed Miui 9 MiFlash showed me it was succesful, but now I´m stuck at the MI Logo and cant go in fastboot mode. Also i think I can´t go in EDL-Mode because when i try to short the test points nothing happens. So neither MiFlash or Fastboot is recognizing my phone. What can I try?

Phone got bricked randomly - QUALCOMM HS-USB QDLOADER 9008 (NEED HELP)

I was using my mi a2 and it randomly freezed, then i restarted using power button, but he didn't turned on, now it is just black screen and i can't get into bootloader mode or turn the phone on.
Bootloader was locked, never tried to unlock.
I think it got stuck on EDL mode because it shows up 'qualcomm hs-usb qdloader 9008' on device manager on windows.
Already tried to use mi flash tool to flash the last ROM, it recognize the phone but fails every time.
Neither adb or fastboot recognizes the phone.
Some errors that i had using the tool:
Failed to open the SDCC Device slot 0 partition 0 (it shows up only on version 2019.11.15.0)
Cannot receive hello packet (when i get this error, i hold the power button for a few seconds then i try again only to get the error below)
Error when flashing storsec.mbn
Can someone help me?

I downloaded mi flash tool 2016.08.30.0 and i can successfuly flash the rom, but still got black screen with no response.

A year ago i had the same issue kinda. The only thing that worked for me was flashing mi 6x stock rom and after some trial an error it flashed and it fixed. The only problem is i have a mi 6x forever. Basically download mi 6x stock rom. Try that mi flash tool and keep hard rebooting and click flash button right after it vibrates. If lucky sometime will work and flash. If nothing try older versions of mi flash tool. Good luck.
all of you have the same problem ... you bootloop into edl mode because you have ARB4 triggered ..that means the only stock you can flash in miflash is ARB4 rom ( latest most up to date )
you also need patched programmer file since flashing ARB4 requires miui account
the fix to this problem is documented everywhere and explained lots of times ...just read ..follow this guide and one-click tool to unbrick
next time read ......a little ..

softbrick mi a2

Hi
I've got a mi a2 that's softbricked. It randomly came up asking to go to recovery mode and after that, died. It now wont go past fastboot (can't enter recovery, gets stuck on the android one splash screen). I'm having a mess on with adb because the usb debugging was never enabled - any workaround?
Thankyou.

Phone stuck on fastboot

Hello everyone! so my redmi k20 pro which had a mi9t pro rom on it fell into some water. First it was ok and after a few hours it shuted down and now it stays on fastboot mode all the time.
The problem is that I can't get my 2 computers to recognize the device (tried with adb and xiaomi mi flash tool). Any suggestions before I just throw the phone away?
edit:
I managed to flash a stock rom with Mi Flash but the phone keeps going back to fastboot and I also tried to flash twrp but after the flash the phone goes back to fastboot. Any suggestions?
Any one?

mi 8 not booting

I have my friends Xiaomi mi 8. It keeps freezing on the miui screen when booting up. It simply won't boot up. The bootloader is locked and I've tried everything. I've tried flashing new firmware via fastboot I've tried flashing twrp and orange fox I've even tried tried flashing pixel experience but the bootloader doesn't allow it. I've downloaded the XiaoMitool v2 and mi flash tool but nothing is working. When I boot to recovery and try to wipe data it just gives an error saying it's failed. I tried using the edl boot bat file and when it reboots to edl it just restarts and freezes on miui. ive tried edl from the back pins on the phone but the computer isnt recognising it and ive got the qualcom drivers installed but still no luck. Also when I try flashing miui fastboot firmware the program gives an error saying something about the flash script. Is there anything I can do to fix it or to atleast unlock the bootloader remotely without the need of the phone being turned on? ive heard of the msm tool but i coulnt find anything for the mi 8 only oneplus. Any help is appreciated thanks!
