    2- there is an arrow there when you click on it , it should show the qualcomm modem.

    No need to Reboot your phone .
    If your phone is not showing on the PDC please follow this :

    1- Download the Qualcomm Drivers :

    http://www.mediafire.com/folder/5mzfw32i8dlp5/Qualcomm Drivers

    2- Connect your phone to your computer via USB.
    said:

    3- Go to Control Panel – Device Manager .. you will see two an unknow device.
    Right click on the first one – Update Driver – browse my computer drivers - Let me pick form a list of available drivers- click on Have Disk ..- show all devices browse then go to the Qualcomm Drivers that you download earlier.
    Then do the same to the other unknown Driver. choose 9018 for both unknown drivers.
    Then follow the steps to Enable VoLTE .

    I can't get past adb reboot ftm. I just get the OnePlus logo, no Chinese text or reboot. I just have to force power off by "Volume up" and "Power" press. Any ideas?

    Hi!

    Thanks, but not working one OP7.

    First, no chinese text after reboot, but adb shell seems to work. Second, PDC throws error: "QMI connection not ready please use usb driver version 1.00.32". Any idea?

    Thanks.

    Hello Guys:

    Do you have lost VoLTE/VoWiFi after rebooting the device? After a reboot I need to run the procedure again to enable it. Is there a way to enable it permanently?

    Thanks in advance.

    You shouldn't loss the VoLTE and Wi-Fi Calling after reboot/ restating the phone .

    Any how , you will lose the VoLTE and Wi-Fi Calling ..after any new update from Oneplus .
