What is it mean? How to do that?
Sorry.

Run EFC explorer “as administrator” and connect to your phone if not done earlier.
Backup to PC “carrier_policy.xml” and “carrier_policy.xml_Subscription01” from “/policyman/” folder.
Replace “carrier_policy.xml” and “carrier_policy.xml_Subscription01” from “carrier_policy_14032021.zip” package with “Discard” “Clean-Up Option”. (Right click on file, “copy Data File from PC..”)

Maybe I'm wrong with this line?
"package with “Discard” “Clean-Up Option”. (Right click on file, “copy Data File from PC..”)"

"Discard & clean-up?"

Im just doing right click, copy data from pc and replace the file


edit: idk why but in PDC india was "inactive" and when im activate it again im get error
but when im start again PDC its "active" its ok?

You should make all changes in PDC in moment of EFS Eplorer connecting and scanning file system.
Also don't forget to deactivate and then remove "Oversea-Commercial_DS" profile. It's important step. Read carefuly manual and repeat the instructions exactly.

After reactivation profile "efsprofiles" folder always overrided with default config. You have to make sure, that “India-VoLTE-Vodafone” Sub0 and Sub1 is active, and “Oversea-Commercial_DS” is removed in PDC. Then, repeat this steps:
Run EFC explorer “as administrator” and connect to your phone if not done earlier.
Backup to PC “overideconfig” and “overideconfig_Subscription01” from “/efsprofiles/” folder.
Replace “overideconfig” and “overideconfig_Subscription01” from “Audio+codec+EVS+HD+.zip” package with “Discard” “Clean-Up Option”. (Right click on file, “copy Data File from PC..”)

I did it all,
I'm desperate, I do not understand why it does not work. I did exactly one by one see my last comment with the pic

To be safe, make a backup via TRWP of your EFS partition BEFORE you flash anything! If you're not rooted, do a nandroid backup via fastboot

Steps:

1) Set your stock dialer app as default
2) Download and install “Logkit+v1.0.apk”
3) Open dialer app and enter *#800#
Scroll down to Function Switch and then tick-mark the “VoLTE”, “VoWifi” and “VTSwitch”. Exit from app and reboot phone. Go to Settings->Wi-Fi & Network->Sim & Network->Sim 1 and enable “VoLTE” & “Wi-Fi Calling” options. Repeat step for SIM 2 if necessary. Reboot phone.
4)Download and install to PC “QPST_2.7.496” + “qud.win.1.1_installer_10061.1.zip”
5) Enable Developer options and “USB debugging”
6) Download and install “engineeringmode_V1.01.0.171117173719.25c8842-26.apk”
Open dialer app and enter *#801#
Set “Full-port switch” to ON
7) Connect your phone to PC via USB and allow USB debugging on phone
Run ADB as administrator (if you haven’t download and install to your PC)
In CMD:
ADB reboot ftm
You should see some Chinese characters on display
8) Go to Device manager. You should see two "IN2010" devices in "Other devices" section. You need device with PID "MI_00", in my case it's second one. You could check, who is MI_00: Right click on device, properties, Events tab (look at screenshot).
When you find correct device, right click "Update Drivers", "Let me pick from a list...", select "Ports (COM & LPT)", select "Manufacturer -> Qualcomn Incorporated, Model -> Qualcomm HS-USB Diagnostics 90B6"
9) In CMD:
ADB shell
setprop sys.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb
10) Run “as administrator” PDC from QPST package. Select “Qualcomm HS-USB WWAN Adapter 9091” from list. In some cases PDC can’t connect to your phone. There is a strange solution:
Run EFS explorer from QPST package “as administrator”, select device with filled "EFS" and "Banner" fields and connect to your phone. In the moment of connection PDC works as excepted. Listing of EFS explorer takes a lot time, but after successful connection PDC stops working again. Close EFS and repeat step to finish all following steps in PDC.
In PDC right click on "Oversea-Commercial_DS" and deactivate “Sub0” and “Sub1”
Click on “Oversea-Commercial_DS” again and click remove.
Select “India-VoLTE-Vodafone”, right click and SetSelectedConfig for both “Sub0” and “Sub1”. Then click Activate button. Close PDC.
11) Download and extract “Audio+codec+EVS+HD+.zip”
Run EFC explorer “as administrator” and connect to your phone if not done earlier.
Backup to PC “overideconfig” and “overideconfig_Subscription01” from “/efsprofiles/” folder.
Replace “overideconfig” and “overideconfig_Subscription01” from “Audio+codec+EVS+HD+.zip” package with “Discard” “Clean-Up Option”. (Right click on file, “copy Data File from PC..”)
12) In ADB:
ADB reboot
13) Install “com.oem.oemlogkit_1.0.200929184727.270d7d2-1.apk” to return stock logkit.
14) Open dialer app and enter *#801#
Set “Full-port switch” to OFF
15) Disable USB Debugging if necessary.
16) Set back your custom dialer if necessary.

That’s all. You have VoLTE/VoWiFi/ViLTE/EVS HD+ codec. Icons in dialer and curtain.

After update to latest version VoLTE was not working again. I think we should repeats this step after every update, until OnePlus (if) fixed this issue.
Hi, sorry but can you explain how to do nandroid backup via fastboot? My phone is not rooted.

Hi, sorry for the interruption again. I tried following the same method on my OP7T, and it gives me this error. My phone is neither rooted nor the bootlocker unlocked. Does it require to unlock bootloader? And one more thing, after using the command ADB reboot ftm, my phone reboots but no any Chinese language appears on the screen. May be my phone is not compatiable? Model is HD1900 OP7T. OS running 11.HD65AA.
