    upload_2020-12-11_20-30-53.png

    when you connect your phone and go into engineer mode then select Rndis what mode does your phone go to or do you set it at? mine automatically goes to "tethering" mode and if I switch to files transfer it disapears but im able to view it in file manager and if i switch to no transfer then i get my phone twice (IN2025) with a yellow triangle. which i take to mean no windows access but I can still see it with ADB devices

    ok, ok.. i kept re reading what you sent last and so I put my phone onto no transfer mode and had the 2 IN2025 with trianges show up, I updated the drivers to the one you suggeted, tried it, no change, rebooted the phone and laptop still nothing changed the drivers from Qualcomm HS-USB MDM Diagnostics 90B6 v2 to v1, no change, unplugged and replugged the phone and voila.. efsinfo gave me the info.. and of course everything else worked as it should from that.. I rebooted my phone and now can conform that I I VoLTE and VoWIFI workinng great on OP8 Pro on OS11.2.2

    Thanks, confirmed working here on a 7Pro, Freedom Mobile on Android 11 OB1.

    I had to use this mbn file instead: https://mega.nz/file/KcFCzSzS#tgoVBtdaWqLW4ZMyDXbuuIimDD7vhjQZsqwNSL7yiDw and to get PDC to display my phone, I had to run adb shell, su, setprop sys.usb.config diag,serial_cdev,rmnet,adb after enabling full port mode. I also used the drivers given here: README - Google Docs

    If anyone has any problems with the steps just tag me. Tip: try copy pasting EFSInfo command, I would get an error if I didn't do that even though the command looked the same.

    Wow, this is really interesting. Any idea if it would work with Public Mobile? Technically on the Telus network but not sure if they even support VoLTE.

    Sorry about this, but I'm back looking for information once again.. I just installed OS 11.0.4.4 and lost VoWIFI and VoLTE again.. and once again I can get everything done up until the efstools part.. where all I get is the

    Use serial port 'COM5'
    Critical error. Bad command

    Ive tried many of the qualicomm drivers all with the same result. (it always wants to revert back to driver Qualcomm HS-USB Diagnostics MDM 90B6)
    Thanks for new ideas and help. if there is a secret or way to find out what driver efttools wants with new update Im more than willing to learn and help others where I can

    thanks

    So I am under the impression that we are still not able to use the volte and vowifi. I don't understand why OnePlus keeps bringing out updates for us without just unlocking these features to begin with

    Please help. I'm getting the exact same error. How did you fix it?

    I am making sure my EngineerMode - Engineer Mode Toggle is ON; My USB Debug is ON; and that USB file transfer is turned on (I can see the phone in Windows Explorer).

    What am I doing wrong?

    We can't have VOLTE working on OP9 pro until Koodo officially supports the phone....which will never happen...sadly....

    Not 100% right because it worked on my OP6T. Just needed to ask the customer service to enable it in my account. when its activated you can see it in self serve -> add ons

    I can confirm this works even if your on Koodo it will add VoLTE to your profile as an add-on which most Koodo CSR won't do or know how to do. WiFi calling will work and if OnePlus ever gets official carrier support your VoLTE will work right away without doing anything.

    Thanks to all your tips I managed to get everything done with no errors on my new oneplus 8 pro, 11.0.5.5.IN11AA (no root) with Shaw (freedom).
    I had no luck getting 'EfsTools-0.10-modded-1.2' to work without the 'critical error Bad command', but 'EfsTools-0.10-modded-1.1' worked for me. Even though everything seemed to go smooth I still haven't been able to get VoLTE or VoWifi to work at all. Just to confirm I performed some of the steps correctly:
    • in PDC I selected 'Commercial-TMO' and confirmed that it stuck after reboot.
    • I copied the 'mcfg_sw.mbn' file from 'Pixel 4 android 11 mbn\Pixel 4 android 11 mbn\mcfg_sw\generic\Pixel\NA\Freedom\pixel_VoLTE' downloaded from a link above into the EfsTools folder.
    I just bought this phone and would really like to get this working or I will have to return it so I'd appreciate any tips. Would it make any difference if I root the phone? I would be willing to root but would like to avoid if it's not necessary.

    It just worked for me.
    I have a one plus 7 with OOS 11.0.1.1 in France
    My operator is Orange, I used the efs method, I copied the Bouygues Telecom mbn from a mi 9t that I founded on phonandroid.fr, then contacted Orange to enable volte and vowifi and everything works fine
