Modify MODEM for VOWIFI

[headshotde]

Hey Guys,

many people got VOLTE and VOWIFI activated on Pocophone, OnePlus and Mi8 by editing the Profile of Modem with Qualcomm PDC tool.
here is the tutorial for OP6 / 6T

/* Disclaimer */
This is at your own risk.
I am not responsible for broken phones, lost IMEI numbers, damaged EFS partition, whatever.

Telekom germany users:
Only step 1 & 2 are required!
However, it is recommended to use the "H3G_Denmark_Commercial" Profile, as it has no restrictions.

1. Enter *#800# and select "oneplus Logkit" --> "Function Switch" --> "VoLTE switch", "VoWiFi switch" and "VT switch".
If "VoLTE switch", "VoWiFi switch" and "VT switch" are not present, then install this APK "OEMLogKit.apk" and restarts!
Now "VoLTE switch", "VoWiFi switch" and "VT switch" should be available under *#800#!

2. After you have selected "VoLTE switch", "VoWiFi switch" and "VT switch", restart the device,
and in the "Settings" under "SIM & Network" select "VoLTE and WiFi-Calling".

3. Go to your computer and install both.

Qualcomm QPST Diag x64 Treiber
QPST_2.7.474
Important: Do not run any other Qualcomm drivers on your computer, please deactivate them before, otherwise you will get error messages!

4. Now connect your phone to your computer using a USB cable.

5. Open the phone app and enter this code *#801#.

6. Now a new menu appears and switches on "Serial" and "Full-port switch".

7. Now start the program: "PDC" and connect it to your device.

8. Right click on "Oversea-Commercial_DS" then under "Deactivate" select "Sub0" and "Sub1".

9. Now click again on "Oversea-Commercial_DS" and press Remove below.

Vodafone, Telekom and o2 Germany: Use the "H3G_Denmark_Commercial" Profile

10. Now select "H3G_Denmark_Commercial", right click and select "Sub0" and "Sub1" on "SetSelectedConfig".
Now click again on "H3G_Denmark_Commercial" and below on Activate.

11. After you have done everything, restart the device!
The "VoLTE or VoWiFi Logo" should now be visible in the expanded status bar.

I try to connect with MIA1 but no chance to get connected with 8.1 and 9.0 Roms

maybe one way is edit a Modemfile with correct Profile ????

Is it possible to enable Volte and VoWifi in Mi A1.

I am gonna say yes. I have been successful in this in a UK network.

I have been trying this for long time and almost gave up. But I was trying trying everytime to fail but at last to win.

What do you need

Stock ROM with August security patch version 10.0.12.0
A Carrier support these two function
Magisk flashable VoEnabler zip from guithub.

Instructions

Flash the stock ROM
Install magisk
Install VoEnabler
Dial *#*#4636#*#* and confirm you have Volte and WiFi calling enabled
Go to phone app, settings, WiFi calling, select WiFi preferred.
Reboot voilà

This worked for me. I hope this works for you guys.
All the best

To enable VoLTE use this in dailer *#*#86583#*#* and it should pop-up "Carrier restriction .. disabled.", works on the latest stock (may not work on some older versions). Afterwards *#*#869434#*#* and you get another pop-up notification "*Blah* *blah* disabled". If you have carrier support for both of it, after reboot and activating in settings app it'll work. Using this method from 7 till now, full stock and it survives OTA. After clean flash (fastboot) for some builds it fails (for example first pie builds).

Yeah and when I try to flash the downloaded zip magisk is complaining that it is not flashable

Dont tinstall the zip downloaded from github.
You have to create a new zip containing the "META-INF" folder etc in the root.
