Hi, I want to extract qcn file of my pixel 3 and followed other steps. After stressful searches, I was almost done with the following links

1) https://forum.xda-developers.com/pixel-2-xl/how-to/guide-qxdm-port-activation-pixel-2-xl-t3884967

2) https://forum.xda-developers.com/pixel-3/help/qxdm-pixel-3-limited-success-help-t3887152

steps I followed
1) bootloader unlock
2) factory image (android 9) from official google
3) Twrp recovery
4) Magisk from link 1
5) Module (Pixel 2 diag port.zip) from link 1
6) Mi5 Qualcomm drivers from link 2

and with that, I got diag port somehow opened but it only gets on MTP connection via USB but no proper detection in QPST. I tried to backup qcn file with partial detection of COM port but it says "checking connection" and then "backup failed no phone attached".

Is there any way for this? I'm really stuck with my mobile network problem. :crying:
P.S: just to make it clear, my question is not for VoLTE or PDC.


Update:-
I managed to get detected properly via Modem port but not in QFIL.
1) Magisk and Module from link 1
2) "QUD.WIN.1.1 Installer-10037.3 Setup" Qualcomm Drivers
3) Put phone in MTP connection
4) Following commands in adb
Code:
adb shell
su
setenforce 0
setprop sys.usb.configfs 1 && setprop sys.usb.config diag,serial_cdev,rmnet_gsi,adb
5) open "QPST Configuration"
6) Add port
7) Add Modem port

With these steps, i get manage to get detected in QPST Download and able to make a backup of "*.xqcn". But after editing and restoring, there is no such change. Am i missing something?
