Hello,

I am running this procedure:
https://xdaforums.com/t/howto-aquaris-x2...k.4239267/
to unbrick an Aquaris X2.

I run a PC with Windows 10.
I installed:
- ADB drivers
- Qualcomm USB Driver V1.0 (HS-USB QDLoader 9008 Qualcomm driver)
- QPST tool

I managed to enter EDL mode, the PC correctly recognize the phone under HS-USB QDLoader 9008 (COM3), and I could flash the emergency package. Unfortunately the IMEI are gone.

So, I rooted the phone with Magisk.
I installed Qualcomm_Diag_QD_Loader_2016_driver
I run the commands:
adb devices
adb shell
su
setprop sys.usb.config diag,adb
Then, in Device Manager, I see under Other devices: Active 1 (my phone), but no way to get the HS-USB Android DIAG 901D.
I tried to reinstall, remove the drivers, no luck.

Any idea how to troubleshoot this?
Thanks

What did the phone get detected as before and after you ran the adb shell command
Did you try reboot after running the command then checking if its detected correctly in device manager?

Thanks for helping.

When I connect the phone to the PC, in Device Manager there is a new line appearing:
> Universal serial bus devices
> ADB interface

When I run adb devices: I get the serial number, no changes in Device Manager
When I run adb shell, then su: no changes
When I run setprop sys.usb.config diag,adb: I see the phone under Other devices: Active 1, with an exclamation mark.

After that, as you suggest I run the command: adb reboot
After the reboot is completed I see:
> Universal serial bus devices
> Active 1 (no exclamation mark)

Then after around 15 seconds, it is back to:
> Universal serial bus devices
> ADB interface

Rerun this command
setprop sys.usb.config diag,adb:

send a screenshot of what your phone is detected as in the device manager

Hello,
Here are some screenshots, after I run:
adb shell
su
setprop sys.usb.config diag,adb

I also tried to uninstall and install the Qualcomm drivers.
I noticed that in Programs and features, there is only one line: Qualcomm USB drivers, appearing after I install the driver "Qualcomm USB Driver V1.0". But there is no new line when I install "Qualcomm_Diag_QD_Loader_2016_driver".
Is this normal?

Is the device baseband known or unknown?

Baseband is unknown, yes

I will suggest you flash full factory firmware first to fix unknown baseband, then write IMEI in diag mode

I tried to flash the full factory firmware, from:
[ Login to download]
The phone is unlocked, I passed the command:
fastboot flashing unlock_critical
Then in fastboot mode, from the folder containing the above firmware, I run:

C:\Users\Morbac\Desktop\BQ X2>fastboot devices
AAB00012877 fastboot

C:\Users\Morbac\Desktop\BQ X2>sdm636_fastboot_all_images.bat
error: no devices/emulators found
Device does not match ZANGYA and cannot be flashed. Check the FW.
Press any key to continue . . .

So it happens that I cannot flash the original firmware. Can you help on this?

It says the device you want to flash doesn't match the device (ZANGYA) the firmware is intended for
