T-mobile June security (NKG47L) update no VoLTE or Wifi-calling

Has anyone flashed the NKG47L June Security update for Tmobile/Fi Carriers to their Pixel? If so, did you lose VoLTE or Wifi Calling or both?
Wifi Calling and VoLTE were working fine on N2G47O and then I flashed the NKG47L OTA to my Pixel, which I am using with T-mobile, and I can no longer make a call without dropping to HSPA, and calls will not be made over wifi anymore.
I have a Verizon Pixel that I am using on Tmobile, so it wont let me unlock the bootloader to flash another image. I cant flash the OTA for NJH47B because it says its older than my current baseband.
just wondering if anyone else has the same problem so I can know if its my phone or the update.

Yes, no problems. Currently running Dirty Unicorns. Wasn't on stock long enough to check if Volte and wifi calling was working. On Dirty Unicorns with tmobile June update, it's definitely working

Thanks.
would be good if someone stock could answer as well. I'd like to know if its just my phone before I wipe and start fresh

The volte and wifi calling issue I had was fixed by a factory wipe. Sux that I had to do it, but it's working properly now on NKG47L

[GUIDE] Activate VoWiFi / WLAN Call

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...

Android 11-based custom ROMs only connect to 4G/LTE

I've tried multiple Android 11-based custom ROMs for Redmi 4X (santoni), i.e., Bliss, HavocOS and crDroid, and all of them cannot connect the phone to 2G (GSM) and 3G (WCDMA) networks even though I've confirmed that these networks are available in my area. However, 4G (LTE) works fine and connects almost instantly. When I've tried an Android 10-based ROM (ReloadedOS), I was actually able to access the 2G and 3G networks. So, is this a problem inherent to Android 11-based ROMs? And how can this issue be fixed? Thanks for all your help!

A phone's networking capabilities are preset by vendor ( read: Android's OEM part ) not by phone's Android itself.

Does this refer to the device firmware from the manufacturer? If so, I've tried flashing different available firmwares for santoni, but every time the problem still persists.
I've tried flashing the Android 10-based crDroid ver. 6 ROM and now my mobile telephony service is working as I've wanted. So, I really think there is something wrong within Android 11 that prevents access to 2G network which is easily done in Android 10-based ROMs.

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.
Much appreciated!

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.
FYI - since upgrading from OOS11 to OOS13 my model number has changing from KB2000 to KB2005 using the standard OTA upgrade process.

Oneplus 8T KB2005 no LTE/WI-FI Calling/VoLTE

Hello,
I'm on the kb2005 and i don't have any options for wifi calling, volte or LTE.
I'm on OOS 13.1 in Canada.
Before i upgrade my phone, what options do i have? What am I doing wrong?

I have the same issue on my KB2003 since 13.1. No wi-fi or incoming/outgoing calls on either SIM. Had to put my SIMs in other phones before factory resetting which accomplished nothing.
I need to downgrade to 13.0 or try a different variety of 13.1. It does not appear, based on posts, to be a widely experienced problem.
If you have found a solution, please share.

When you insert sim-card smartphone (in this example 8T) checks what carrier it belongs to and activates looks in the inbuilt profile base and activates the appropriate one for your carrier.
If the phone doesn't find the one for your carrier it activates the generic one, which may work only partially for your carrier or don't work at all if settings mismatch.
That worked generally good in OOS11/12/13, but OnePlus changed smth in OOS13.1 which makes magisk VoLTE enabler modules only partially (but still) effective, and also specified by you problems occur.
You can try to activate engineering mode (easier via magisk module) and change carrier profile manually from within phone.
It can be also done via PDC software in Windows.
If you don't want or can't do the above mentioned you can try different carrier sim cards or apply for support (carrier or oneplus).

Thanks for the suggestions. I have time this afternoon to try things.
I had no idea my perfectly configured and operating phone running T_Mo and Verizon SIMs would get crapped by a seemingly minor update. I would have waited for Android 14 if I had.
Wondering why I can't even get Wifi working. I may MSM back to 11 and try to get back on13.0 and STOP!
I don't want to keep using my Pixel 6 Pro because it's size & weight are enough to make me miss my 8T.

I have Oneplus Engineer mode unlock & VoEnabler modules active in Magisk. No icon indicating VoLTE active when both SIMs indicated VoLTE prior to 13.1 . I have QPST installed but after poking around I think I need to throw in the towel on 13.1 and somehow fastboot flash to downgrade or MSM to A11 and upgrade. How do I stop before 13.1 since I will likely only be offered a jump to 13.1?
Can I boot OrangeFox or TWRP and flash an older than current version since my bootloader is unlocked? I have the payload for OOS 13 F.63.
