Which Magisk module you are referring to? I am not using any Magisk module for VoLTE/VoWiFi.

The path modify /data/user_de/0/com.android.phone/files/carrierconfig-com.android.carrierconfig-XXXXXXXXXXX.xml where is it exactly? Is it in the root directory of the phone or somewhere else because I can't find it?

Also, the link in your quote https://developer.android.com/refere...rConfigManager doesn't work.

Can you please specify the steps on how to do this so that I can replicate it?

Many Thanks

I applied this method volte/vowifi worked.

But, when I do twrp wipe cache, IMEI addresses have been deleted, operators are not working right now.
[OnePlus 5T  Guides, News, & Discussion] renzs:
you didn't backup EFS partition before doing it?
[OnePlus 5T  Guides, News, & Discussion] rideordie16:
Installing the EFS backup did not fix it.

I did a clean installation, fixed.

But this method is not safe, IMEI addresses will be deleted when updating ota or wipe cache.

Which mbn did you use? I'm using the vodafone india one I found in the firmware folder
[OnePlus 5T  Guides, News, & Discussion] Joolz78:
I used the Telstra file within the AUNZ folder.

Let me know how you go.
[OnePlus 5T  Guides, News, & Discussion] VoltaGe86:
very odd

I tried that file and I got an error on the first sim

Error on upload file '/ims/imshandoverconfig'. EFS error. Code = 26

The second sim was fine

reboot and no change. *#*#4636#*#* says IMS not registered :(
[OnePlus 5T  Guides, News, & Discussion] markstein:
Same error message here. EFS scattered. Had to reflash to get phone working again. Does not work on 5T.
[OnePlus 5T  Guides, News, & Discussion] VoltaGe86:
Well somehow I've managed to get VoLTE functioning on Telstra here in Australia with the OnePlus 5t! I'm not entirely sure what I've done though :|

Some or all of these steps may not be required.

1. Followed step 2 and 3 of https://xdaforums.com/rog-phone-2/how-to/guide-enabling-volte-vowifi-v2-t4028073)

2. Followed step 4 of https://xdaforums.com/rog-phone-2/how-to/guide-enabling-volte-vowifi-v2-t4028073) using mbns-mi9t\aunz\telstra\commerci\mcfg_sw.mbn

3. Reboot, no change

4. Repeated above, using mcfg_sw/generic/apac/vodafone/volte/india/mcfg_sw.mbn from the phones firmware folder

5. Reboot, no change

6. Tried manually adding APN from https://xdaforums.com/oneplus-5t/ho...n-carriers-t3817542/post81465467#post81465467

Add two APNs as follows

APN = ims

MCC = 505

MNC = 01

APN Type = ims

APN Protocol = IPv4/IPv6

APN Roaming Protocol = IPv4/IPv6

Bearer = LTE

APN = hos

MCC = 505

MNC = 01

Authentication type = PAP

APN Type = xcap

Bearer = LTE

7. Repeated above using https://github.com/JohnBel/Qualcomm..._sw/generic/aunz/telstra/commerci/mcfg_sw.mbn, the rationale here is that the other two mbn files are from phones not approved by Telstra, however the Nokia is. Absolutely no idea if this has anything to do with it.

8. Reboot, success!

Initially vowifi worked but it has since stopped working. VoLTE remains functioning and works when calling, the little HD logo shows up and has been functioning rock solid for the last few hours. VoLTE persists when rebooting or toggling aeroplane mode.

VoWIFI would be nice but since I've been trying to get VoLTE working over the last few years I'll take what I can get!!

Hope this helps someone.

EDIT: when sending the mbn on the first sim I get the error Error on upload file '/ims/imshandoverconfig'. EFS error. Code = 26. Unsure if this is an issue, fixable or not but I am still able to get VoLTE functioning on reboot.

[OnePlus 5T  Guides, News, & Discussion] SGH-i200:
The link to the Android documentation is only helpful, if you like to learn which VoLTE config values do what.

Check the 'What does this module change?' section of the Magisk module description: https://github.com/edgd1er/voenabler/blob/master/README.md
[OnePlus 5T  Guides, News, & Discussion] panoramixmeister:
Ι will have a look and try to figure this out. Thanks

Also....

he path modify /data/user_de/0/com.android.phone/files/carrierconfig-com.android.carrierconfig-XXXXXXXXXXX.xml where is it exactly? Is it in the root directory of the phone or somewhere else because I can't find it?

You need to be rooted to be able to edit the files in this directory.

I am already rooted but can't seem to find this path even when using root explorer.
[OnePlus 5T  Guides, News, & Discussion] Flying Scotsman:
Could not for the life of me get QPST (kept failing to install) or the other tools to work, but for some reason just using the Magisk module to enable VoLTE and VoWIFI was enough to get at least VoWIFI working but it keeps disappearing at random (i.e it'll be in the status bar then disappears before coming back again) and I'm not sure if that's intentional or not.

VoLTE doesn't seem to work even though the toggle is there and it's enabled (probably because I can't enable the Serial etc option with that *#801# code).

This is for 3 UK on a OP5 (using OOS 10). Could not flash the EFS due to the tools not installing (or the tools linked in the OP leading to a dead page). The dialler codes also don't work (I installed Engineering mode seperately just in case but the codes still do nothing).

Not sure how to go about this as every guide I've seen so far either links to a dead tool, uses QPST (which just fails to install regardless of the version) or uses dialler codes which don't seem to work (numpad just goes blank).
[OnePlus 5T  Guides, News, & Discussion] vipsms:
It is well-known here that QPST/PDC doesn't work for OOS 10 neither on Oneplus 5 nor 5T. But to enable it on OOS 10 or any AOSP Android 10 rom, there is a method mentioned in PE telegram group that I followed last week, and worked with me successfully. I'll sum it up here for everyone [Thanks PE Team].

Requirement :-

- Unlocked bootloader

- TWRP recovery installed, no need root

- OOS 9.011 FULL rom zip

- OOS 10 Firmware ONLY zip

- OP Qualcomm Softwares [QPST_2.7.460 And QUD.WIN.1.1+Installer-10037.3+Setup]

Before you start: Create a TWRP backup of your [EFS And Modem], and store in your PC (recommended)

Instructions :-

1) Make sure you're running OOS 9.0.11 rom with TWRP installed already

2) Boot in TWRP, and Flash OOS 10 Firmware ONLY zip, then reboot system

3) Open the dialer: *#800# --> oneplus Logkit --> Function Switch --> enable VoLTE + VoWifi switch

4) Connect your phone to PC via USB, Open dialer app and enter *#801#

Set Serial and Full-port switch to ON

5) Run " PDC " as Admin, deactivate overseas modem then remove it. Then, close " PDC " app

5) Run " PDC " again as Admin, scroll to the bottom of the list to find [India-VoLTE-Vodafone]. Active it for sub 0 and sub 1, then press on the activate.

6) Close " PDC " and eject the USB, Reboot to TWRP recovery, and create a backup of your new [EFS And Modem] and name it VoLTEoos10 as an example

7) At this point, follow the steps to install your favorite android 10 rom (whether OOS10/AOSP) as normal.

8) Before rebooting system, restore your new [EFS And Modem] backup [VoLTEoos10].

* This way you will be on the required firmware with your modified modem/efs.

* if you installed OOS 10 full rom, repeat step (3) to enable VoLTE + VoWifi switch
[OnePlus 5T  Guides, News, & Discussion] markstein:
Too difficult

Not practical for users already on OOS 10 and far too difficult. No other way to revive PDC?
[OnePlus 5T  Guides, News, & Discussion] Flying Scotsman:
Thanks for the post.

Still have an issue with using the dial codes however. The code is definitely correct, but it never launches the associated app (it just clears the input screen). Weirdly NO dialler codes work and I haven't changed anything (still using the stock dialler etc).
[OnePlus 5T  Guides, News, & Discussion] redcord:
sounds not very hard, but where can i get "OOS 10 Firmware ONLY zip"? There are only full ROMs all around the internet
[OnePlus 5T  Guides, News, & Discussion] vipsms:
It actually isn't imo, I found the firmware at crdroid's link (thanks CR).

Oneplus 5T:

https://sourceforge.net/projects/crdroid/files/dumpling/6.x/firmware/

Oneplus 5:

https://sourceforge.net/projects/crdroid/files/cheeseburger/6.x/firmware/

If you installed the latest "OOS10 hotfix full zip" , then install "10.0.0-H1 firmware" .

---------- Post added at 08:30 AM ---------- Previous post was at 07:40 AM ----------

I haven't tested the oneplus dialer codes on OOS 10 since I am on android 10 custom rom atm. But I am sure the codes work fine on OOS 9 pie.
[OnePlus 5T  Guides, News, & Discussion] rahatbek:
GOOD

it's working for me too at 5t
[OnePlus 5T  Guides, News, & Discussion] twinsen.net:
Let me understand it more - the clue is to wipe out the phone and install previous Oxygen OS (Android 9), then make changes in EFS with well known PDC as before, make backup of EFS, upgrade to Android 10 and restore EFS from the backup - that makes VoLTE and VoWiFi working? And at every update, just restore of EFS will make the trick? The bad is that I didn't think about the EFS backup before upgrading to Android 10 ;)

EDIT: please tell me if to install TWRP I only need to unlock bootloader, and I don't need to have a root (because I heavily use Google Pay) - so Safety.Net checks will pass?
[OnePlus 5T  Guides, News, & Discussion] vipsms:
Unlocking bootloader only results in "uncertified" play store status on OOS, so Safetynet fails. Usually flashing Magisk certifies the device but I haven't tried it on OOS.

Some AOSP ROMs passes the safetynet out-of-box without flashing magisk like Derpfest (i'm on it atm) and pixel-experience I believe.

In my opinion, since you use google pay heavily, I suggest you stay on stock oos10 until a new method of activating VoLTE appears in the future.
[OnePlus 5T  Guides, News, & Discussion] VoltaGe86:
I don't use it often but I can confirm Google Play works for me. Android 10, unlocked bootloader latest twrp blu_spark and magisk installed.

I'm an unrelated issue-My banking app was force closing if magisk was installed. I used the magisk hide function in the settings which renamed the app then added the bank app to the hide list and it works now :)
[OnePlus 5T  Guides, News, & Discussion] Pedimento:
Tried it and at the beginning it didn't work, because I couldnt enable volte or wifi-calling from #*801# because there was no option in function switch, finally I followed procedure and flashed xXx 11.6, after reboot it worked. I use OOS.

Hi friends, we had volte problem with new update, old PDC method gives error. I saw another method in a few places, before me there was post about it, but was so complicated for read. On 4pda site was written so easy., if you know how to use command director on windows, it is not a troublesome process.

Step 1: Download https://4pda.ru/pages/go/?u=https:/...EfsTools-0.10-modded-1.2-win32.zip&e=97287430 and https://drive.google.com/file/d/1PiVhB35MPx19sxqxQ4svgOvPXL1dxobt/view open both to a same new folder on the desktop.

Step 2: than dial * # 801 # and turn the serial and full port switch buttons on and connect the phone to the computer.

Step 3: In the lower left corner of the screen, the command directory appears in the search as CMD. Type "cd desktop" into the current directory, you switch to the desktop, if you know the name of the folder you opened, type "cd (folder name)", going into the folder, write "EfsTools.exe efsInfo", you can copy and paste it. When you press enter, the port number and some text are displayed on the screen.

Step 4: then we close the mcfg file: write " EfsTools.exe writeFile -i mcfg_autoselect_by_uim -o / nv / item_files / mcfg / mcfg_autoselect_by_uim " into this script and press enter, then write it: " EfsTools.exe writeFile -i mcfg_a_u_a_a_a_select / nv / item_files / mcfg / mcfg_autoselect_by_uim -s 1 "

Step 5: Download https://drive.google.com/file/d/1Unr8reL3_nLJK9hBs85huXdV_HBXKjaf/view?usp=sharing file and open it in the previous efs folder.

Step 6: We write this in the " EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -v " directory and press enter.

Also for the 2nd sim

write " EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -s 1 ".

voila. go to the phone to recovery, make wipe cache and reboot. Wait a while when it is fully open, the volte text will appears, if not, try the same steps with another usb port, i do it on first try.

i have no root, no bootloader open.

After update OP5T to Android 10, missing switches to VoWiFi and VoLTE.
In this tutorial i will show how to fix this.
It is enabling VoWiFi and VoLTE even in Poland with T-Mobile, Orange and Play carrier.

0. Make sure that you just enabled the VoWiFi and VoLTE in your carrier first !!!
1. Download and install the old LogKit: https://www.dropbox.com/s/8kk77qzo4..._1.0-1_minAPI28(nodpi)_apkmirror.com.apk?dl=1 or https://www.apkmirror.com/apk/onepl...lease/onepluslogkit-1-0-android-apk-download/
3. Type *#800# --> oneplus Logkit --> Function Switch --> enable VoLTE and VoWifi switch
4. Open Settings --> WiFi & Intenet --> SIM & netwok --> enable VoLTE and VoWifi switch
5. Connect your phone to PC
6. Type *#801# in Phone app and enable Serial and Full-port switch
7. Download and unzip the EfsTools with config files includes: https://www.dropbox.com/s/aslwvbmegy0dbin/EfsTools-0.10-modded-1.2-win32.zip?dl=1
8. Open CMD on the PC, navigate to the folder when you extract the files (eg. cd c:\EfsTools-0.10-modded-1.2-win32)
9. Now execute the following commands:
EfsTools.exe efsInfo
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
EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -v
EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -s 1

Thats it. Commands with "1" on at the end are for the second SIM card.

I have tried the method from OnePlus forum, but this is not working for me. All commands pass, but no effect. I have tried few MBNs - no result. No idea what could be wrong. I own OnePlus 5, not rooted, not unlocked and for SIM1 I use PlusGSM (Polkomtel, Plus Internet na Kartę), for SIM2 I use nju mobile (Orange branch, contract). In Android 9, the MBN which was working for me was for the Everything Everywhere UK, but now it's not working. Tried for Orange, Plus, some generic ones - nothing. I think, we would need some explanation, how this modification works, what if defines, and how the phone tries to connect to the server, on which port, and so on... Could it be, that the operators disabled OnePlus devices on the network level, as those are not VoLTE/VoWiFi certified? Are those MBNs are for pretending that our devices are something else like some certified manufacturer?
