Hard Bricked 4x

Hi,
I have a following problem with my Redmi 4X. I tried to flash new rom and reboot my phone on twrp. When the phone shut down nothing happens anymore just black screen. No fastboot or recovery mode. When I contact the phone to Windows pc it shows in device manager: Qualcomm HS-USB Diagnostics 900E (COM20). I have tried to flash new rom with QFIL and Miflash (tried to change the driver to Qualcomm HS-USB QDLoader 9008).
With QFIL the error is: Download Fail: Switch to EDL FailFailed to switch to Emergency Download mode.
With Miflash the error is: Cannot receive hello packet. MiFlash is trying to reset status!
Any suggestions?

Already tried that. Doesn't seem to change a thing.

Shouldn't it turn the driver to "Qualcomm HS-USB QDLoader 9008" after test point method?
This is what shows in command prompt:
C:\Windows\system32>adb reboot edl
error: device '(null)' not found
C:\Windows\system32>adb devices
List of devices attached
C:\Windows\system32>

After the test point method you will see a new "9008" device in the Device Manager.
Then all of the above commands will be completely irrelevant and useless.
In the 9008 mode use MiFlash, not QFIL/QPST, to reflash your phone.
Cheers!

The test points seems to change nothing. I think that after the " adb devices" command I should see my device listed but that is not the case and therefore impossible to flash rom. Somehow I should be able to change the "900E mode" to "9008 mode" without changing the driver manually and I think the test point method should do just that.

Here is video of what I have tried to do. If someone could point out what to do differently to get the flash work I would be very grateful.

Windows 10 will not accept the 9008 driver because the driversignature ist not signed from Microsoft.
If you will unbrick it with Windows 10 64bit look here: https://www.youtube.com/watch?v=2d8KEruHWPg
and here: https://www.maketecheasier.com/install-unsigned-drivers-windows10/

Had allready done that also. Gave it another try without success

Is the Qualcomm 9008 driver now installed?
Did you start the mi-flash tool with administrator privileges?

I installed the Qualcomm drivers but device manager still shows 900E driver unless I manually change it to 9008.
edit:
I finally succeeded with test point method. Now flashing. Im so grateful to you ConradB.

Thank you buddy .. Your 4 years old post help me to turn on my hard brick redmi 4x.
I don't know the actual reason of hard brick but The situation was my phone was in condition like
1. Possible to go in fastboot mode
2. When turning on there is only mi logo for fraction of second.
I tried test point method as described . It turned on in one attempt..I just want to add something. I face some issues after test point flashing . So I just flash miui again . Then It's working perfectly fine. After Test point flash check your battery. Maybe fully drained. Just charge it and turn it on..
I am posting this just for Information..

Bricked 9T pro

I bricked my 9T pro when I mistakenly flashed it with 9T rom
Now the phone is recognized in device manager as QUALCOMM HS-USB QDLOADER 9008, It won't let me go into Fastboot mode to flash with Mitool.
screen is black all the time, no vibration while pressing power button.
Is there any solution for this, guys? I really need a phone to do my job and I'm kinda in a pickle right now :crying:

Download proper drivers of qualcomm from below link (all instructions are given)
https://xiaomifirmware.com/downloads/qualcomm-hs-usb-qdloader-9008/
Then use xiaomi tool v2
https://www.xiaomitool.com/V2/
It will detect your device

Thank you for the reply! I already had installed that drivers and the problem is, that Mitool V2 says No devices in fastbood mode found. I can't put my phone in fastboot mode :crying:

EDL mode
Put your phone in EDL mode and then flash the official ROM with mi flash tool (search on google how to put Mi 9T pro in EDL mode) do it with your own risk as it involves removal of back glass panel and shorting of 2 pins on the motherboard.

Question Mi unlock/USB keeps connecting/disconnecting

I was wondering if anyone experience the same.
I want to unlock my bootloader but everything I connect my phone (in fastboot) to PC I hear windows connecting and 2 seconds after that disconnecting in loop.
Mi unlock therefore doesn't see my phone, and in device manager you see "Android" appearing and disappearing.
I used the original USB cable.
I've installed mtk drivers as well as the Xiaomi USB drivers.
It's only in fastboot, normal mtp mode does work well.
But I can't unlock my bootloader this way.
Please help.

where did you find the drivers? I am looking for them

Found it on xiaomitools website. (Googled for Xiaomi mtk drivers)

I had the same problem and how I fixed it was just going into device manager in windows and installed my drivers manually from there and now the phone is detected as an "Android adb interface" when it's in fastboot.

Which driver did you use? I've tried installing drivers when they pop up in device manager but it somehow wouldn't let me install them successfully.

Have you tried this?

I just solved the problem. You have to disable signature enforcement and then download the driver installer from here (Pick Redmi Note 10S and then choose the Mediatek Driver or click here). Follow the guidelines and that should be it!

Bricked flashing custom ROM then locked the bootloader

I made a mistake while I was flashing a custom ROM PixelPlus UI in my device Redmi 9
after seccessfully flashing it I locked the bootloader and now my doesn't turn on either going in fastboot mood.I need help to fix it..plz plz plz

Hi, make sure that your battery is full, then hold VOl + and power key together and connect USB cable and see if is detected. The other things is to flash with edl mode but you need testpoint and flash tool like MRT... See over the internet for your model...

Vol+ and power key doesn't shows any sign.

Try then with VOl - and power but keep pressing and plug usb cable, if that doesn't work you need edl flashing....

Does edl supports in MTK processores?

Hi, sorry I mixed your device with Mi 9 model.... For MTK chipset you need BROM mode, so try to hold both VOL + and VOL - and plug usb cable and see if is detected... If it doesn't then send your device to nearby service center in order to flash with service box...

It shows something in ports......and few seconds later it goes away.

Good sign, then follow this flashing... use only if you have same chipset!

Mine is Mediatek G80 / MTK6769

Have your issue resolve and if so what exactly have you done, one of my friend done the same and facing the issue.

You are screwed if you locked the bootloader. Nothing you can do. At all.

Connect phone to pC using test point and follow guides

Trigger device to 9008 mode-
1. Remove USB cable and battery (Change a new chipset, UFS
should be empty)
2. Connect the battery
3. Device will boot into the emergency download mode
4. Confirm that the device manager has detected “Qualcomm HS-
USB QDLoader 9008 (COM x)”.
& Its may help too
