[GUIDE] Activate VoWiFi / WLAN Call

[T00bN00b]

Did anybody got VoWiFi working on Pocophone with new Andriod 10 MIUI ?
Since I've updated to it, PDC-Tool keeps telling me "QMI connection not ready, please use USB diver version 1.00.32 or later and fix connection before using PDC tool"

Update:
I got it work. Using a different version of QPST-tools solved it.

I can't activate Vowifi either because I can't modify the build.prop file. an error message prevents me from each modification of the file. My Pocophone is rooted on Mi-globe Rom 11.0.4. stable.
----
later
------
I finally succeeded, I changed my root explorer ... and the command on build.prop works fine :
persist.dbg.ims_volte_enable=1 persist.dbg.volte_avail_ovr=1 persist.dbg.vt_avail_ovr=1 persist.dbg.wfc_avail_ovr=1 persist.radio.rat_on=combine persist.radio.data_ltd_sys_ind=1 persist.radio.data_con_rprt=1 persist.radio.calls.on.ims=1


I have Vowifi on my Pocophone in android 10 (Miui 11.0.4)

Thank you thank you thank you.
been working in a subterranean office for a few months now with a PocoF1 running LineageOS 16.0 (25thjan2020)
On EE in the UK I couldn't get VoWiFi working and no amount of *#4636#*#* was going to fix it.
setup PDC as shown. Disabled EE Commercial on Sub1 and enabled DT Greece on Sub0 and Sub1
As soon as I rebooted I started to get calls !
Icon didn't change, but now shows a signal and in the quickpulldown actually says "EE Wi-Fi Calling"

I would like to get vowifi working on my old Xiaomi Redmi Note 3 pro (Kenzo) running very latest HAvoc and most up to date Xiaomi firmware.
The problem is no one with this phone has found a way to make PDC work with it.
So does anyone know a manual way to install DT Greece and remove the default ?
Any help would be much appreciated.

Hey mate,
which version of QPST did you install? I have the same problem with my Mi8 (but on Pixel Experience) and tried many QPST versions and different drivers :/

Check post #68, probably your ROM doesn't have the correct USB mode set and the small APK did the trick on custom ROMs.

Will try, thanks. The problem was not the detection of my phone. It gets detected in PDC as 9091 but I always get the driver version error. But I will report back :good:

I used QPST 2.7.480 and latest drivers from qualcomm.
However, I needed to set usb connection to automatically switch to file transfer mode in developer options first.

Best of luck to you.

Didn't work. -.-"
None of those commands worked:

setprop sys.usb.config diag,serial_smd,rmnet_qti_bam,adb && setprop sys.usb.configfs 0
- or try -
setprop sys.usb.config diag,serial_smd,rmnet_bam,adb && setprop sys.usb.configfs 0
- or try -
setprop sys.usb.config diag,serial_smd,rmnet_ipa,adb && setprop sys.usb.configfs 0

The device does nothing afterwards. With the app the same. After this I can't change sys.usb.config anymore and I have to reboot. If I use:

setprop sys.usb.config diag,serial_cdev,rmnet,adb

(which worked last year with AOSiP and Android 9) the phone gets detected in PDC but with driver error.

Didn't work for me. Always getting driver error...

I wrote you to use the app, not the commands - did you try the app?

I tried with app at first but it's exactly the same >.>

Edit:
This is from logcat if I press the "Enable Diagmode" button:

Did you read my whole answer?

I tried to help. You wrote "Didn't work. -.-"" and then listed the commands which didn't work - which I didn't tell you to use - thus the "Didn't work. -.-"" to me was connected to a different context and was ambigoius to me, that's why asked back.

Last advise: Make a good TWRP backup, go back to MIUI, do the modificaions running on official MIUI and go back to your original ROM via TWPR. The modifications are done in EFS thus after you finished your work it will work on any ROM that supports it.

But you know what, IDC, GL;HF

Why so vicious?

My hope was not to do the whole flash thing with miui. I thought I get it to work without. I don't know why or what does not work :/ But thank you anyway.

But why did I had to do the procedre again after updating from Miui11 A9 to Miui 11 A10?

No problem with that, I'm just curious.

Probably it had some modem mcfg updates.

After upgrading to latest crdroid 6.2 with 11.04 firmware on my Poco f1 I too lost VoWifi. PDC won't connect anymore with same error as described here. Installed latest MIUI11 11.04. neither PDC nor *#*#869434#*#* helped there either so I guess that upgrading to 11.04 borks VoWIFI for good. Hopefully there is a way to use PDC with 11.04. All described solutions described in link below don't work.

Hi there, anyone has any luck with which carrier profile to use for Australia (Optus or Telstra)?

 

[Maximus1a]

From german ISP:

öffne die Telefontastatur
gib dort *#*#86583#*#* ein
eine Rückmeldung "VoLTE Carrier Check disable" sollte erscheinen
unter “Einstellungen --> SIM Karten & Mobile Netzwerke” sollte es jetzt möglich sein, "VoTLE" einzuschalten

Los user here with an issue.
I've followed the instructions to the letter and I've activated DT_Greece, however this doesn't stick. Te moment I reboot the phone, DT_Greece gets deactivated and everything reverts to how it was before I started. Any idea how to stop it from doing that?

 

[agstn.tanmay]

is it gonna work with any custom rom?
