First of all a BIG thanks to ed-gonzo
He made this possible
This is the instruction to activate VoWiFi / WLAN Call on the Poco F1
Its tested and verfied to work with EU ROM (Oreo , Pie and Q based) and german provider o2 (Telefonica)
Before you read on i want to make clear that I am not responsible for bricked devices !
Basic requirements are root rights to do this mod
Maybe latest 2020 Qualcomm Diag QD-Loader Windows 10 Drivers signed are needed for this to work.
!!! Before doing this Mod you should backup EFS-partition !!!
- download QPST tool and install
- enable USB debugging in Developer settings
- now either go to terminal app and type:
Code:
su
setprop sys.usb.config diag,serial_cdev,rmnet,adb
or
adb from PC
Code:
adb shell
su
setprop sys.usb.config diag,serial_cdev,rmnet,adb
- connect Poco F1 with original USB cable to PC
- start PDC (from QPST tool) on PC
- Poco F1 should be recognized by PDC (if not install Qualcomm driver and check Device Manager)
- activate corresponding profile (in case of german o2 its DT_Greece)
- install VoLTE & VoWiFi Enabler Magisk module (optional) or activate setting with dialer code *#*#869434#*#*
- restart Poco F1
- Voila
FAQ:
Q: What are the requirements for VoWiFi
A: A provider resp. plan which includes VoWiFi
Q: How to know if VoWiFi is working ?
A: Put phone in airplane mode and reactivate WiFi only. If you are able to make a call then VoWiFi is working.
Q: Does this only work with MIUI ROM ?
A: No ... its reported to work also on Custom ROMs like LOS, crDroid ...
Thx for this guide! Have been waiting for this.
Does this work with custom ROM (LOS)?
in case of german o2 its DT_Greece? are you sure? german carrier and greece?

Ok thx will give it a shot as soon as I get access to a windoze PC :highfive:
Ok this definately didn't work on my Poco-f1 with latest LOS16 and 8.11.15 vendor/fw. Funny thing that VoLTE now seems to be gone (Device switches back to H+/E). Got it back by restoring efs. Has anyone else been successful with this running custom ROMs? Even without this "hack" I have been able to activate VoWIFI after 8.11.5 update but it didn't work so I guess this depends on FW version.
Two things - a little offtopic though: Any Idea if this can be tried on the MiA1? I suspect that xiaomi doesn't include support in it's firmware for this device at all and I 'm afraid to cripple both my devices (Poco and MiA1) at the end .
Has anyone had success getting HDVoice with BT headsets on the Poco-f1 with custom ROMs? Sorry for asking this here but in the LOS thread I seem to get ignored with this question / bug report.
@saski4711
to bad that its not working for you.
It defintively works with EU ROMs based on Oreo or Pie.

Yeah bummer. Will give it another shot the next days maybe I messed up somewhere. Isn't this device supposed to get VoWIFI by default with the Pie update anyway? Maybe this will work OOTB with final pie?
not works with EU pie rom to me too. from Sri Lanka we have VOWIFI network. tried switching many profiles but not works .

Dont know ... i'm on Stable EU ROM 10.0.6.0 (based on Oreo)
I know for sure it worked out of the box after pie update on stock beta with a service provider in Greece.
Can make settings appear with *#"#vowifi#*#* but being in India don't think providers support vowifi so doesn't work.

2 diff statement.
Can enable with code but doesn't work in india.
It worked for a friend in Greece without doing anything immediately after pie update.
What I was suggesting that maybe and just maybe if provider supports it ,vowifi can be enabled simply by code.
It is working perfect. I did some test calls on wifi. Thumb up..... BTW I'm on German Telekom D1

could you please tell us which ROM you are using and which profile you activated within PDC ?
I'm using 8.11.27 global beta and I modified the DT_greece section. Set sub0 and sub1 to active.
Opened dialer and dialed *#*#vowifi#*#*
ok this works, just needed a bit more work for WoWiFi in my case
after a reboot it kept returning to my default carrier config (VoLTE working just fine anyway)
so what I did was to remove my carrier config from within PDC Tool, just that by doing that it defaulted to a non-VoLTE config
well, removed that also and this time it kept DT_Greece config on both subs
VoLTE works and VoWiFi also (carrier Orange Romania)
ps. don't restart phone if you want to test new configs
just click on activate and enter airplane mode then exit (keeps testing faster)
I've gotten as far as I can with my Mi Mix 2S, works on both AOSP and MIUI to allow the radios to be enabled, and the settings to appear in MIUI (AOSP usually shows them anyway).
With this said, I tried only enabling the WiFi option on the carrier that already had the sim activated...
I see many people here on different carriers in the EU who enabled the DT_Greece options and voila. Is this an accurate conclusion? I'm wondering if I just need an answer from a carrier other than my own to acknowledge the WiFi option exists to turn it on? Being in the US it seems as if the DT_Greece config could cause some problems, but it's not an option in my list. I don't know at this point.
Edit:
Tried all the US bands and even a few others, specifically ones that said WiFi. None worked so far, I'm going to cry! :crying::crying::crying:
I tried this on a Redmi Note 5 Pro but after selecting the device in PDC it throws an error message and doesn't show the list of carriers.
I've tried QPST 2.7.420 and 2.7.474 and a couple different pie roms, windows 7 and 10 but it always fails.
I can use EFS Explorer and dump the NV data just fine though...
I bought a Chinese version Xiaomi 12x recently and was trying to enable the VoWifi. I've tried to use *#*#869434#*#* and succeed to see the VoWifi option in the settings. But after I enabled it, nothing happens. Is there any way to enable it in Chinese version ROM? I have set this phone up with my needed APPs and data so I really do not want to flash it and set it again Or is it possible to enable VoWifi by flashing MIUI EU or Global?
Thanks!
I read some xda/reddit posts on this topic. It seems:
- OOS 11 is the only option to stably run kb2005 (oneplus dual sim) firmware on kb2007 (tmobile single sim). And a dual sim card tray can be used so that the second sim works for volte/vowifi (wifi calling).
- MSM Tool is the way to go to flash kb2005 firmware on a kb2007 phone to rebrand as EU version KB05BA, per this thread https://forum.xda-developers.com/t/...m-unlock-or-bootloader-unlock-needed.4188491/ . From there, kb2005 firmware can be installed with Local Update option.
- If OOS12 is installed and rollback is needed then this thread is very helpful https://forum.xda-developers.com/t/downgrade-oneplus-8t-kb2005-from-12-to-11-stable.4424381/
Does this sound about right? Or am I missing something on this issue? Thanks in advance!
Okay the device has arrived. I plan to stay on OOS11 for a while. 1) No real benefit added by OOS12; 2) VoLTE and Wifi Calling on US carriers like T-Mobile have been reported stabler on OOS11.
Below are the steps I took:
1. Use EU MSM tool; follow the instructions here (run MSM tool .exe file with administrator permission; can use adb tool to get into edl mode easily): https://forum.xda-developers.com/t/...m-unlock-or-bootloader-unlock-needed.4188491/
2. Download Oxygen Updater, from the device list, select oneplus 8T;
3. Enable advance option in Oxygen Updater; now kb2005 firmware should pop up, download it, and then follow the instructions about "local update" using this file.
oops this automatically brings me to OOS12.
Trying the OnePlus official rollback apk now...
Okay rollback apk doesn't work and quits when I click any firmware.
These are the correct steps:
0. Use carrier unlock from the setting to unlock T-Mobile carrier lock first.
1. Use EU MSM tool; follow the instructions here (run MSM tool .exe file with administrator permission; can use adb tool to get into edl mode easily): https://forum.xda-developers.com/t/...m-unlock-or-bootloader-unlock-needed.4188491/ note: after reboot I have dual VoWifi working already on KB05BA firmware.
2. Just use system update if it is showing 11.0.13.13.KB05BA.
This sticks to the EU firmware, as dual VoWifi already works on T-Mobile USA.
Hello, could you confirm that dual sim is working by following the steps above? I just received my T-Mobile 8T yesterday and found out it has only one sim slot.
Yes, it was actually just that simple. SIM unlock. MSM tool. And one system update.
You might have to be careful with the last part tho because the latest system update may bring you to OOS12 and dual SIM will break. You might need to search for Oxygen updater and find a way to update to the latest OOS11 firmware. Oh also Global is the best among all firmware versions.

Thank you so much
I followed the steps above but for some reason the Oxygen Updater still update my device to OOS12. I managed to downgrade back to OOS 11. I am still waiting for my dual sim tray from Amazon. Just to confirm, the latest OOS is 11.0.13.13.KB05AA right? Also, on the "About phone" page, the model is still KB2007, is this ok?

Hi PPLs,
Has anyone managed to force VoLTE Calling to be enabled on OOS12? I am using the OnePlus 8T and my wife uses the OnePlus 9. I have had to rollback both phone the OOS11 after testing OOS12 and realising the OnePlus Log Kit app no longer works, therefore no way to enable VoLTE calling.
For now we are holding on to OOS11 (with the Log Kit fix) until we find a fix in OOS12, otherwise we both might be forced to look and another brand of phone, which I really don't want to do.
Just as a side note, I was using a Realme XT which I bought in 2020 which had VoLTE enabled by default as soon as it recognised the SIM, so the network is capable, but I get no support from Vodafone AU as the OnePlus phones are imported as they are not generally sold in Australia. It seems the same story with all Australian carriers.
Also, my main reason for not rooting the phones is since we use them as daily drivers and need to use secure banking apps.
I know a few people have asked similar questions before, however I'm hoping there might be some progress on this soon.
Thank you!

Actually there is a way, but not straightforward and if you mess up, you can brick your phone.
First of all you need to unlock engineering menu in OOS12 and in MBN section try to enable VoLTE. If after this volte still doesn't work, enable diagnostic ports via engineering menu, and only after via QPST and PDC activate carrier profiles for your region (Vodafone Australia).
P.S: Making it via root is easier, as Volte is enabled via Magisk module, and diagnostic ports for PDC & QPST are enabled via basically two commands in adb.
Why not try LineageOS 19.1(Android 12)?
Volte works fine out of box.
You just need gapps, magisk and some module to pass safteynet check, then it's all good.

Thank you for the tip! I'm pretty comfortable with digging around like that.
I'll definitely give that one a go in the near future. It's my daily driver at the moment so I need to pick a time or use an old backup phone for a while.

Will give it a go on my wife's OP9 which I've kept on OOS11 because on this.
FYI I recently bought a OP10 Pro EU version and everything works perfectly including VoLTE & VoWIFI.
Looks like maybe the Global versions are having VoLTE issues in Australia on some carriers.
Only just bit the bullet 2 weeks ago with the OP8T and installed LineageOS 20. Works great out of the box.
I might consider re-flashing the stock OOS13 ROM on the 8T just to try this fix too.

Thank you so much @ghost.ign !!
I finally got around to unbricking my almost forgotten OP8T KB2005 International Version using MSMDownloaderTool and tried the tweak using the link you provided. It worked!
Best part was, it worked on the current OOS13 and persists after reboot, as well as removing & reinserting the SIM. Very happy!
It's now time to update my wife's OP9 and do the same. Fingers crossed.

I'm unable to confirm, maybe someone else can. I can however suggest that there's is likely no harm trying. I believe it should work across all carrier unlocked models.
Give it a go and report back if you can share.

Recent updates have made this method a more dangerous option. I can't go back
If you know how to put it back together, I'd love to know.
i am running the t mobile version with the global firmware. i updated with the indian version before everyone realized that it wasn't a global version (like every past OOS update). had the no signal issue (i'm assuming the indian version doesn't have the right radio bands for the us versions). i rolled back to OOS 11 and got my data signal back, waited for the global/us version (which just came out) but when I try to flash it I am still getting the same no signal issue. Oxygen Updater still thinks i have the Indian version, it says:
"It looks like you've selected the wrong device, "OnePlus 7 Pro" instead of "OnePlus 7 Pro (India)"
In Android Settings, phone is listed as GM1917 (Global/International Version)
Any help would be greatly appreciated!
I was able to regain tmobile data by flashing the modem.img from oos11 to finally fix this. Give it a shot go here. Do a data backup in case.. I had no problems until I did a data wipe after setting up the phone. I am not sure if this is a good fix or not but it works on my phone. Anyone else have a suggestion I am open to it.
So to do this I need to unlock my bootloader and setup TWRP? Right now everything is stock other than the global firmware...
