Can we repair the imei of K30 Pro Zoom by QPST Tool?
Would be good to figure out how to get the phone to connect with QPST -
Connects in device manager but not in QPST - always says No ESN.
I've tried all these but get the same result -
setprop sys.usb.config diag,adb
setprop sys.usb.config diag
setprop sys.usb.config diag,serial_cdev,rmnet,adb
setprop sys.usb.config diag,serial_cdev,rmnet
setprop sys.usb.config rndis,diag,adb

These change the ports in device manager but none work with QPST
Not sure if it's a driver issue.. I'm using the latest qpst 2.7 build 496

I'm using a Google Pixel (Sailfish) and successfully got to DIAG mode, ran QPST, exported the Backup in Software Download window... BUT I am facing issue where it seems like EFS is encrypted as I converted my IMEI to HEX and searched for it in HexEdit and also Winhex to no avail. Anyone have insight here, am I doing something wrong? Or is it just that Google encrypted the IMEI in the EFS and it can't be modified at all even through QPST?
how did you managed to get sailfish to go into diag mode?

    - QPST 2.7 ;
    - QDLoader HS-USB drivers pack ;
    - ADB & Fastboot ;


    STEPS:
    - Install drivers and QPST, reboot the PC ;
    - Enable developer settings on your device ;
    - Enable Debug on your device ;
    - Connect the phone on the PC ;
    - If don't* popup an "Diasgnostics Port COM" on device manager (usually this port is enabled in the factory rom)

    *Open an cmd window and enable it with this command "Diagnostics Port" with this commands:

    The QPST Configuration tool worked as a charm without any errors whatsoever. I have just one query. The XQCN file generated is 989 kB in size. Is that the right size? If not, what size should it be?
    Yes aren't an large file :)
