Mi A3: Diag mode and unknown device in QPST & QXDM - Xiaomi Mi A3 Questions & Answers

I am trying to enable CA on my Mi A3 device. I have unlocked the bootloader and even rooted the device. However, after enabling diag mode, QPST & QXDM is not getting full device information.
To enable Diag mode, I tried two methods and both are working.
Method 1#:
Enable "USB Debugging"on your phone.
Connect it to your PC/Laptop.
Enter below in phone app.
*#*#13491#*#*
Method #2:
Enable "USB Debugging"on your phone.
Connect it to your PC/Laptop.
Open "Minimal ADB & Fastboot" Command Prompt with administrative rights.
Type adb devices and press enter.
Type adb shell and press enter.
Type su and press enter.
Type setprop sys.usb.config diag,adb and press enter.
I have installed the latest Qualcomm drivers and device is listed under Ports(COM & LPT) as Qualcomm HS-USB Diagnostics 90DB (COM4).

However, when I open QPST it is showing the devices as Unkown even though the port is being detected.
When I try to READ or WRITE any values in QxDM, I am getting an error "Diag Error Received: Invalid Command Error Response".
Anyone else had any success with enabling diagnostic mode on Mi A3?

Never tried this, so I can't help you. But, it's an interesting matter. If you find any more things, please let us know.

Some success with the latest version of QSTP 2.7.496.1. The phone is now detected as NICOBAR which is the code name for Snapdragon 665.
However, I have only the old version QxDM v3 which won't work on the latest chipset as per below post.
How to enable carrier aggregation (LTE+) on Redmi note 5?
Hi! How to enable carrier aggregation (LTE+) on Redmi note 5 Global? Does it work on Linegae OS? Best!
forum.xda-developers.com
Until a cracked version of QxDM v4 become available, no chance of messing with LTE NV values on these new Snapdragon chipsets.

@starweb, any success dumping the QCN (XML or not) file though?
I just got an A3 and per my usual tinkering I wanted to dump it all before I start messing with it. When enabling the diagnostics I get the same 90DB port you do, and at some point I got the phone to be recognized by QFIL or QPST's Configuration, but neither of them were able to create a dump of that area.
Under QFIL the operation just timed out, QPST's Download back up function complained about not being able to write to disk. I've had no problems with older phones, although diag ports were usually 9091, not 90DB as in the A3.

I didn't try any dump.
Problem is you need QxDM v4 to mess with these new Snapdragon phones. Old version won't work.

May I ask where you got the latest drivers from? I only find drivers from 2016

XT1022: Failed to validate system image. Connect USB Cable. Device Locked - Status 0

Hello Guys,
Laid my hands on a spare XT1022 from my friend that was supposedly junk for him because of the following reason. The phone starts of directly in fastboot mode and there's no sign of a normal startup. Although i've connected the USB cable and it shows up as "Motorola ADB Device" under Device Manager, still the fastboot shows Connect USB Cable error. The exact scenario is depicted in a similar pic below :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
.
The phone is fully stock and was treated to this message upon a random reboot. I can get this back to life by flashing TWRP & Custom ROM's but for that first of all need to unlock the bootloader, for which the data cable needs to be shown as connected. USB Debugging wasn't enabled.
Would be highly obliged if someone could shed some light in the right direction and help out on this
Regards.
@lost101, Need your expert advice on this. Others, please do help.
'USB Debugging' most likely does not need to be enabled with Condor handsets in order to unlock Bootloader. That is a security feature that only appeared with later devices.
The USB issue seems obviously driver-related. The easiest solution would be to boot into a Linux Live CD (such as Ubuntu), and gain fastboot access that way - drivers are not needed in Linux. Then fastboot flash the latest XT1022 factory firmware image.
*Note: In linux, use the 'sudo' command prefix:
sudo fastboot devices​

The result was exactly the same which i get in Windows command prompt. The list of devices shows a blank. I've installed the drivers and rechecked them, the device is listed as "Motorola ADB Interface" under Device Manager :
and; shows as Fastboot condor S in hardware eject box.
I fail to understand why it isn't showing as connected only in the fastboot menu. Fastboot reason is given as "fall through from not charger boot mode". The device shows only the fastboot screen by default. If any other option like recovery etc is selected, it throws the error message as bootup failed. Scenario is exactly of the same pic which was posted in #1.
Please suggest the next step.
@BBThumbHealer - Starting to look like Bootloader corruption. An unbrick method could be applied to potentially restore a functional Bootloader. One exists for Falcon 5.1 - unsure about Condor at this time.
I would try to eliminate the USB cable as the problem by trying alternatives.

I was stucked in the same problem yesterday. I succeeded and recovered my Moto E to live again.
As in the screenshot you posted. Your bootloader is locked. You need to unloack the bootloader. To do so follow the steps in the link given below :
https://accounts.motorola.com/ssoau...ct/standalone/bootloader/unlock-your-device-b
Login or create your Moto ID and follow the steps as described.
After that you'll have to flash the firmware again. hope this helps.

Hi to everybody
I am trying to correctly connect my new Ticawatch Pro with WearOS to my notebook win 7 Ultimate TEST MODE
The procedure is asking to put in fastboot mode the device but I can't because I don't know the procedure
Is there any workaround ??
I want underline that on this notebook I am able to connect without problems all my android devices like Xiaomi Mia1, Mi6, LG Nexus 5X and others
EDIT
I have applied the procedure having he smartwatch switched ON (=adb mode)
Now when I connect the device to the netbook it is recognized as ADB device:
I can see it into Manage resources (as Android Composite ADB Interface),
I can see it under list of USB devices (as Ticwatch pro)
BUT I CANNOT see it into Explorer in order to explore its hard memory space
Any suggestions ??

Can't unlock the bootloader on my Xiaomi Redmi Note 5

Hey!
I am having difficulties unlocking the bootloader of my Redmi Note 5. I have already rooted a meizu phone and a lenovo tablet before and had no problems. However, with this one, I am able to enter the bootloader using the following command.
Code:
adb reboot bootloader
However, when I do this:
Code:
fastboot oem unlock
It outputs the following:
Code:
FAILED (remote: 'Token Verify Failed, Reboot the device')
fastboot: error: Command failed
The command
Code:
fastboot oem unlock-go
outputs the same results and rebooting my phone doesn't resolve the issue.
Additionnaly, using the Miui Unlock App doesn't work because it doesn't recognise my phone when in bootloader.
Please help!
Thanks in advance.
PS: I am using a Win10 64bits PC
Edit: I tried an older version of Miui Unlock and it detected my device, but couldn't unlock it. It stopped at 99% and output "couldn't unlock"
IMHO it's always recommended to check for boot-loader can get unlocked
Code:
adb devices
adb shell "getprop ro.oem_unlock_supported"
If returned value is 1, then it's supported otherwise it's not.

You are supposed to use the mi unlock tool. Not these simple fastboot commands (xiaomi wants to make unlocking complicated)
Here is a steb-by-step guide
1. Make a Mi account
2. Apply for an unlock here https://en.miui.com/unlock/
3. Download Mi unlock by clicking on the unlock now and then download Mi Unlock.
4. Download the Mi Unlock app to PC, and sign in with your Mi Account;
5. Shut down your phone manually, and hold Volume down key and Power button to enter Fastboot.
6. Connect your phone to PC using USB cable and click "Unlock".
You will probably have to wait some time (3 days, maybe a week or even a month).
it's been some time since I have unlock my Xiaomi phone so these steps might be wrong. If yes point that out please.

As I said in my post, I have tried using Mi Unlock. I have done all your steps up to the 6th because the app doesn't allow me to click unlock. I am guessing that it doesn't detect my phone in fastboot mode. About the time I have to wait, is it the time between when I apply for an unlock and when I can unlock my phone? This would explain why I can't unlock it. However I saw on another thread that Xiaomi removed the need to apply and wait to be able to unlock a phone. I don't really know how to feel about this one...

Do you have fastboot/adb drivers installed?

I'm pretty sure I do, because I have already rooted devices before. How do I check?

Seppppx said:
To check your drivers (and install) do this.
1. Plug your phone to the Pc.
2. Boot to fastboot (use googles platform tools, download below)
3. Open CMD as an administrator.
4. Navigate to the folder there you have platform tools in.
5. Type "fastboot devices" if you see no output you either have the wrong drivers installed or not installed
(Download the Google USB driver linked down)
6. To install drivers you open your Device Manager in windows.
7. Look for something like "Android Device" there. If it also has a warning sign that means that there are no drivers.
8. Right click on "Android Device"
9. Click on "Update driver"
10. Click on "Browse my computer for driver software"
11. Click on "Let me pick from a list of available drivers on my computer"
12. Click on "Have Disk..."
12. Browser for a driver under "Copy manufacturer's files from:"
13. Find the driver folder in the folder you saved it to and open it.
14. Double click on "android_winusb.inf
15. Click on "OK"
16. Click on "Next"
Done, you have installed a driver.
Download the Google fastboot/adb here https://developer.android.com/studio/releases/platform-tools
Direct download https://dl.google.com/android/repository/platform-tools-latest-windows.zip

Well, I tried and went up to step 5 and there was no output. So I continued the steps, on step 7 I saw that my Adroid Device Driver had no warning sign, meaning that I have the wrong drivers. I continued on with your steps. After step 11, the control pannel shows 2 drivers named as "Android Bootloader Interface", however before step 15, the control pannel shows 3 different drivers named as "Android ADB Interface", "Android Bootloader Interface" and "Android Composite ADB Interface". The second one is selected by default, so I click ok and it installs. However, the "adb devices" and "fastboot devices" commands still show nothing in the command prompt. Is there something I am doing wrong?

Do you get an output to "fastboot devices" that's the thing that matters when unlocking. I managed to my redmi note 4 to unlock without adb.
You also can get adb in the classic system where you boot. That works for me.

No, "fastboot devices" has no output on my computer, but it has one on another computer for some reason. On mine it doesn't and I need it to on mine.

Okay guys I figured it out. I was missing a step. I indeed had to use the Mi Unlock tool, but before doing so I had to enable an option beneath the "OEM unlock option", I don't remember how it was called but everything's fine now!

Question Help with hard bricked K40 Pro. How to flash recovery in EDL?

Hi, I've recently hardbricked my redmi k40 pro when trying to flash some custom roms and custom recoveries. I managed to get it into EDL mode hoping to flash a working recovery from there. However when I try to use the miflash tool it gets stuck on "ping target via firehose", or goes to "write time out, maybe device was disconnected" and I cannot get anything to work. I realized that even if i get past that part that I still require an authorized xiaomi account to flash in EDL mode. So I thought i'd try it using QFiL, however that requires the programmer file for the phone, and from my understanding that's a proprietary file that only xiaomi has and you can only get from leaks and such.
I was wondering if anyone knew where to get the programmer file or if you knew how I could get an EDL authorized xiaomi account so i could use the miflash tool to fix my phone.
Also does anyone know how to fix the "write timeout, maybe device was disconnected"? I have tried different usb ports and different usb cables and I can' get anything to work.
Also is any snapdragon 888 programmer file usable? Or do I have to have one specific to my phone?
Any help would be greatly appreciated as I am very new to EDL mode.

Question fastboot command not working | waiting for any device

Hi all,
first of all: yes, I've used the search function but I couldn't find a solution.
I have a Nord 2 5G device and want to install Evolution X Custom ROM.
I followed the instructions in this forum (and other websites) and managed to downgrade to OOS 11 in order to get into fastboot. The adb command to boot into fastboot mode also worked and my device is saying
fastboot_unlock_verify ok
The device is in fastboot mode which is only for debug Android devices. If you want to exit fastboot mode, please long press volume up and power buttons simultaneously.

However, the fastboot command to flash TWRP does not work. On the command line I can only see

After opening the properties, I can see this:

The drivers for this device have not been installed. (Code 28).
There are no compatible drivers for this device.

So obviously I need additional drivers. I have downloaded the USB drivers from this website: https://developer.android.com/studio/run/win-usb, chose install from hard drive and pointed to the directory I have unzipped the driver set but Windows can't install them. I have also downloaded the OnePlus driver set from https://oneplusdriver.com/download-oneplus-driver and installed them.
Still, it doesn't work.
I am at the end of my rope now. What did I do wrong?
Thanks in advance!

Hi all,
first of all: yes, I've used the search function but I couldn't find a solution.
I have a Nord 2 5G device and want to install Evolution X Custom ROM.
I followed the instructions in this forum (and other websites) and managed to downgrade to OOS 11 in order to get into fastboot. The adb command to boot into fastboot mode also worked and my device is saying
However, the fastboot command to flash TWRP does not work. On the command line I can only see
and I continuously hear the Windows device attached/device detached chime. The device manager shows this:

Have you try to use platform-tools? It has adb and fastboot. I have always used that and no problem
SDK Platform Tools release notes | Android Studio | Android Developers
Android SDK Platform-Tools is a component for the Android SDK.
developer.android.com
Look in Eigenshaften > Details > "Device instance path" (k.A. Gerätepfad?).
What's the VID/PID?
Is that in the stock INF file in android_winusb.inf?
If you want, you can just use Zadig drivers. I can give you "fastbogus.exe".

Select "WinUSB".

Yes, the thing is, I've installed the drivers in the wrong way. I'll try to give a step-by-step guide:
Go to Device Manager and find the Device (will have the yellow triangle. Right-click on it and choose upgrade driver (hope that's what's shown in the english version of Win 11). You'll see this:
Click the second option. You'll see this:
Here, choose the second option at the bottom. That's where I did it wrong. I selected the drivers in the dropdown menu and that doesn't work.
Click there...
and click there to select the diver *.inf file in the usb_driver folder.
That should work. It's important that you use the official Google Drivers (at least it was important here).
Hope that works.

Hi,
I managed to install the ADB google drivers so I can now at least see Fastboot devices response properly but I do not know how to unlock the bootloader as the command "fastboot oem unlock" is not recognized and there is still no menu for the bootloader unlock (only the message on the black screen)
If anyone could help I would be be very grateful.
Thank you.
Best Regards
Lad
