Thanks man.. now my phone (Oneplus 7T HD1900 global OOS 11 stable) is running with volte and vowifi enabled without root. I searched for many forums and tried many methods including root also, multiple times i had to use MSM tool to restore also, but root was not best for me, so i was looking to enable it without root. finally, i am able to enable it. Thanks man, you are life saver. ...
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:

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.

Hi, I went to activate the volte and wowifi to digi romania but doesn't work so I'm off the plane.

Adica am reusit activarea cu metoda ta, dar in mod avion nu merge apelarea. VoWifi nu functioneaza. VladVlad12, am folosit ca si tine mcfg de la H3G. Vreo solutie ?

    Incearca sa folosesti altul, e posibil ca pentru digi sa fie altul.

    Ai activat de la *#801# Engineer mode toggle? Incercat sa activezi și da comanda după

    Da. Engineer mode toggle, usb debug on, USB file transfer connection.

    Cred ca am probleme cu qualcom driver. Am dezinstalat, si am reinstalat Qualcomm QPST Diag port x64. Dar tot aceasi eroare.

    Cand am activate Engineer mode toggle, in device manager nu am qualcomm, si eroare under "other devices"

    Thank you sir!
    it worked like a charm.
    OnePlus 7T Pro McLaren edition .
    Network: Kuwait - Zain.
    Profile used: apac\vodafone\commerci\india

    I used to use PDC to enable VoLTE , but after getting OOS 11 stable update the phone is not detected under PDC .
    keep in mind it only worked for VoLTE for me, I could not get VoWiFi to work before and I did not care . if you have better profile for Zain Kuwait network , let me know!

    again thank you for your solution and steps .

    Salut Vlad,

    Thanks for this tutorial. I have activated VoWifi and VoLTE on my OP 7T Pro. But...

    Using Pixel/APAC/Airtel/pixel_Commercial/ with Vodafone Romania. When i am latched to 4G and using VoLTE, the GPS is not working anymore. If i lock it to 3G, the GPS works back. Can you test also?

    What other configs you recommend to test?

    Cheers

    LE: After trying several configs, i have found one that works with OP7T Plus Vodafone Romania.
    \mbns-mi9t\eu\vodafone\commerci\ireland
    WoWiFi, VoLTE & GPS works alltogether.

    Good luck!

  • Today took the time to update my firmware (in preparation for new crDroid release)
    So by doing the update to OOS 11, ofc I've lost my VoLTE
    Now let me get to share my steps that worked for me (yeah was lazy to follow all those steps from the tutorial)

    Note that this version needs root so if you are unrooted, root your OOS I guess
    1. Download QPST, Tiny ADB & Fastboot (used portable version) and OEMLogKit_1.0-1.apk
    2. Extract the zip and install QPST.2.7.496.1.exe and Qualcomm USB Driver V1.0 (from Driver folder inside archive)
    3. Install OEMLogKit_1.0-1.apk
    4. Open phone app and dial *#800# and navigate to Function Switch and toggle VoLTE switch and VoWiFi switch and reboot
    5. Make yourself a dev (how nice it sounds) by tapping 5 times build number and navigate to System -> Developer options to toggle USB debgging
    6. Extract Tiny ADB & Fastboot v1.1.6 Portable and open "Open CMD" bat file
    7. Now in the cmd window, we make sure adb works by issuing below command in
    Code:
    adb device
    8. Next step is to enable PDC port connection by issuing below commands one at a time (you'll get magisk grant root propmt on issuing su command, so grant that)
    Code:
    adb shell
    su
    setprop sys.usb.config diag,serial_cdev,rmnet,adb
    9. Open PDC app installed on step 2
    10. Deactivate set profile by right clicking it and activate the one you feel it works (used VoLTE Vodafone India)
    11. Enter airplane mode on phone and exit then check if VoLTE works

    Have fun!

    Hi,
    Thanks for the tuto, vladvlad12
    It helped me a great deal.

    I managed to activate VoLTE and VoWIFI for both SIM cards (DIGI and Vodafone Romania) on my OP7 Pro.
    I used the MBNS file from the Pixel4 archive (profile Vodafone Germany : EU > Vodafone > VoLTE > pixel_Germany)

    VoLTE and VoWifi are working great!
    Thanks again!

      Thank you @vladvlad12, worked successfully on my 1+ 7T (HD1900) OOS 11, non rooted.

      Region: APAC
      Carrier: DITO Philippines
      Country: Philippines
      I used Pixel\APAC\Vodafone\Commercial\pixel_IN and it worked. VoLTE activated.

      Hello guys.

      VoLTE and VoWifi has been disabled after updating OOS from 11.0.0.2 HD65AA to 11.0.1.1 HD65AA.
      Then I tried reenabling VoLTE and VoWifi using EfsTools, but executing `EfsTools.exe efsInfo` fails.
      it returns result like below (even with admin command prompt).


      View attachment 5320459

      Does anyone know solutions to this problem, or have same situation?
      Here's my conditions.

      Device : One Plus 7T HD1900
      Oxygen OS : 11.0.1.1 HD65AA

      Note : I've had had my phone VoLTE enabled when OOS 11.0.0.2 with EfsTools before.


      I've just solved the issue by myself.
      5. With your phone connected via USB enter *#801# and check Engineer Mode Toggle switch to ON.
      this time, this step does not work for me, but turning Full-port switch ON works and my op7t got VoLTE enabled again.
      if having the same issue, try turning Full-port switch ON.
      Thanks guys.

      Hi everyone.


      Code:
      /*
      * Your warranty is void. Or vaild, probably?
      *
      * I am not responsible for bricked devices, dead SD cards, Ebolation X,

      * 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

      NOTE: ON custom ROM OEM and Enginer mode does not work. See step 5.1 for custom ROM.
      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

      5. With your phone connected via USB enter *#801# and check Engineer Mode Toggle switch to ON.
      5.1. If you are on custom ROM you activate the enginer mode by entering in adb shell and run the next command:
      setprop sys.usb.config diag,serial_cdev,rmnet,adb
      5.2. Also if you are on custom rom you can use this method or the PDC one, also not using OEM and engineer, just run command from 5.1 and you should see your phone in PDC.
      6. You can test the connection by running this in the cmd window:

      Code:
      EfsTools.exe efsInfo

      Should return something like this:
      efsInfo.PNG



      This should report back some info if everything is working.

      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.

      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.
