iam currently using the old method,
Updates the modem using QPST,
Choose the profile India vodafone,
And the LTE, Vowifi work great,
But the device returns to the default setting Oversea Profile,
from time to time.


in this guide the default profile is what I choose ?
Have you tried deleting the default profile?

Here are the original mbn files extracted from OOS 10.0.1 and used to activate VoLTE at Vodafone Egypt via Vodafone India profile and also working via Telefonica uk too.

    Working like a charm with OnePlus 7T (HD1900 with Oxygen 11 stable) I used Telia Sweden profile for the Mexican carrier Altan with the MVNO Diri. I think should works with the rest of the Altan's MVNO as well.

    what does this suppose to do?
    Just like using the logkit?
    This is Magisk module that activates the toggle of VoLte and VoWifi in setting.

    Hi everyone.


    Code:
    /*
    * Your warranty is void. Or vaild, probably?
    *
    * I am not responsible for bricked devices, dead SD cards, Ebolation X,
    * thermonuclear war, or the current economic crisis caused by you following
    * these directions. YOU are choosing to make these modificiations, and if
    * you point your finger at me for messing up your device, I will LMAO at you.
    */


    First you will need that apps:

    EFS Modded 1.2
    EFS
    mbns-mi9t.zip can use this or can use this Pixel mbns
    OEMLogKit_1.0-1.apk
    EngineeringMode.apk

    1. Enter * # 800 # in the stock dialer, and then click oneplus Logkit - next - Function Switch - next - activate VoLTE switch, VoWifi switch and VT switch.
    2. Reboot device.
    3. Install Qualcomm QPST Diag port x64 / QPST 2.7.474 software on your computer
    4. Unzip EfsTools from above, open up a cmd window and cd to the directory where you extracted it. Depending on how you connect to diag you will need to modify EfsTools.exe.config - if you're connecting via USB you most likely won't have to do anything as it will find the port automatically, unless you have more than one port, in which case you can simply change port from Auto to the COM port of the phone (for example COM13).
    5. With your phone connected via USB enter *#801# and check Engineer Mode Toggle switch to ON.
    6. You can test the connection by running this in the cmd window:

    Code:
    EfsTools.exe efsInfo

    Should return something like this:
    View attachment 5200327


    This should report back some info if everything is working.

    7. Extract efs.zip from above to the same directory as EfsTools.exe, and make sure the mcfg_autoselect_by_uim file is there. Now simply run this in the cmd window, one line at a time:

    Code:
    EfsTools.exe writeFile -i mcfg_autoselect_by_uim -o /nv/item_files/mcfg/mcfg_autoselect_by_uim
    EfsTools.exe writeFile -i mcfg_autoselect_by_uim -o /nv/item_files/mcfg/mcfg_autoselect_by_uim -s 1


    If everything worked you should see no error messages.

    The mbn directory structure is generally laid out like this: <region>/<carrier>/commerci/<country>/mcfg_sw.mbn. For example, the one for my carrier is eu/h3g/commerci/se/mcfg_sw.mbn. Copy the mcfg_sw.mbn file to the same directory as the EfsTools.exe, then go to the cmd window you opened and type this:


    Code:
    EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -v
    
    EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -s 1

    8. If it has worked you should see a bunch of output, but no errors. Try rebooting now, and hopefully after it has booted you will have fully functional VoLTE and VoWiFi.

    If you manage to activate VoLTE/VoWiFi using this guide please let us know your Country--Carrier--MBNS that you used.

    Proof:
    Yes! This is really works for my OnePlus 7 Pro with Android 11

    I am from Hong Kong and my carrier is CSL
    The mcfg_sw.mbn file I am using is under
    sea\hkt\commerci\hk

    I have extracted the MBNs from OP7 Pro. Hope this will help someone.

    Same method worked fine for me, though I got the information and files from different sources, as I have been looking for some days for a solution. Also, it's possible to set the engineer mode using adb, rather then installing the Engineer apk, by writing in adb shell setprop sys.usb.config diag,adb
    I used the Telefonika_UK_Commercial mbn from Pixel 4, so far it seems a lot more stable than the one from OOS (on OOS10 it was continuously switching between VoWiFi/VoLTE every few minutes).

    Romania - Digi.Mobil - Pixel's 4 EU\Telefonica\Commercial\UK, if it makes any difference.
