No VoLTE on Xiaomi.eu and Globe Miui ROMs

Hi guys
I flashed both globe miui and Xiaomi.eu ROM on my Mi5 is using TWRP. Both were based on 7.2.9 beta build. Everything went really well with zero bloats ROM was fluid but there was no VoLTE on both ROMs i tried every possible thing I could like apn , rebooting , swapping SIM cards but nothing worked. Can anyone help me out?

On my global beta ROM, the VoLTE option only appears when I set my location to South Korea but not Taiwan, presumably because the ROM enables the option only for regions where telco's have it. Perhaps you can try changing your location to another region too.

Well , i have the VoLTE switch icon but that toggle doesn't works as there's no sign of VoLTE at all

Hi @chan200606 - your "fix" worked!
It was driving me nuts - EU ROM beta for Mi 6 was working, but the "new" official, global stable for Mi 6 was not... Switching the location to South Korea did the trick...
Since this appears to be a setting, do you have any clue where to edit it? I tried this but mine was already showing "0".

i have 7.9.14 xiaomi.eu version, it gives VoLTE on T-Mobile in Germany but it doesn´t work, as i don´t hear anything

No LTE after switch from xiaomi.eu to LineageOS

Hi XDA community,
i hope this is not a duplicate thread but i could not find one that could help me (if i did miss it shame on me...).
As stated in the title i did switch from a xiaomi.eu global ROM to LineageOS 14.1 nightly yesterday.
When i was running the miui ROM, LTE was working perfectly fine and I do know for sure that my carrier offers it and also the bands supported by the Mi 5 are used in my country.
However after the switch to LinageOS LTE wont work (other networks like 3G run perfectly).
A friend of mine has a Mi 5s running LineageOS where LTE works fine, so i think i probably have some wrong settings.
I did try to change network preference in settings but it did not help.
Hope you guys have some suggestions for me.
Thanks in advance & best regards
Technical information (hope i did not forget meaningful stuff):
Android Version: 7.1.2
LineageOS version 14.1-20170627-NIGHTLY-gemini

Solved...
Thanks everbody that might've wanted to help but somehow it works now.
Might be the proof that the core IT troubleshooting technique of rebooting always is a hint.
Thx and regards!

IMS Services (VoLTE, VoWiFi) on Project Fi AndroidOne Oreo ROM

Hi all,
I just flashed PAYTON_FI_OPW27.57-25-2_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml to my European XT1900-7.
Everything appears to be fine, except for the IMS-Services. I actually lost the ability to use VoLTE and VoWiFi (aka WiFi-Calling, aka WLAN-Calling) that used to be working in the stock Nougat and Oreo firmwares.
IMS-Services are unchecked when opening test menu by typing *#*#4636#*#* in the dialer.
Anybody has a clue on how to get this working again?
Thanks

You can try to install Magisk and "VoLTE & VoWiFi Enabler" Module to it

Thanks, but in the respective thread the author states that he abandoned the module because there are too many issues.
I rather think there should be a way to grab the IMS settings from the Oreo stock ROM and import them into the AndroidOne/Project-Fi ROM....

Low mobile data rate

Hi,
currently I'm using the latest dev Firmeware fw_gemini_miui_MI5Global_8.11.22_c5d7ee6745_8.0 with Havoc-OS 2.3[9.0] and have a mobile internet data rate by around 0,03 MB/s - Independent from any locations.
My local carrier is "Klarmobil" as a sub-brand of Telekom (Germany) with H+ (no LTE). I tried a lot with APN settings. I was a bit confused as normally after installing a new ROM a APN setting SMS is received to apply profile - Not with Android 9. So I called the support and did the APN settings by hand - Nothing changed.
Same issue with Resurrection Remix 7.0.0 based on Android 9 with same Firmware. You have any idea?
Regards,
Georg

Hi,
thanks for you reply. 3 more (maybe stupid) questions:
1. I was thinking that a non dev version lock the Bootloader again?
2. I always read something about the latest dev Version in the Rom section - Is this compatible with any Android 9 ROM?
3. Can I dirty flash the Firmware or need to do a clean wipe?
Regards

1.The global stable firmware for gemini won't lock your bootloader , I have used it in the following Costom Roms citrus CAF, pixel experience,aosp extended ,havoc os ,jdc nougat , resurrection remix pie, linage os pie and several Manny
2.yes it's compatible with Android 9 the LATEST ONE
3.I recommend doing a clean flash because I never did a dirty one

Use VoWifi/VoLTE with LineageOS 17.1

Hi,
have flashed LineageOS 17.1 on my OnePlus 3T.
Ist there any way to use VoWifi/VoLTE with LineageOS 17.1?
Thanks

Yes, there is. Do you have the settings under mobile network to enable VoLTE and VoWifi? Did you check the build.prop? Do you see the following props?
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.dbg.wfc_avail_ovr=1
If not, add them to the build.prop, reboot and try to enable the settings.
I'm running crDroid 6.5 (which is based on LOS 17.1) on my OnePlus3, and I see the settings. And it's working with the German provider Telekom.

you could have asked in LOS 17.1 thread instead of creating a new thread
Sent from my OnePlus3T using XDA Labs

@meiser have edit the build.prob and inserted the tree lines.
Now i have a button to activate VoWifi
Can activate but does not work
Thint the problem was my network operator.
On my OnePlus 6T (with OxygenOS 9.0.9) i must set to H3G Denmark profile manually with special tool, only then it did work.
So i think LineageOS can VoWifi but did not work with my network operator

Well, there're howtos to enable VoLTE/VoWifi by activating the right profile via QPST.

@meiser Have searched, but foud no info or thred to Lineageos and QPST with OP3, all is only fpr original OxygenOS
Maybe you have any URL/Link for me

It was under https://android-hubo.de/thread/7983...te-vilte-vowifi-freischalten-de-nl-ohne-root/
But the site is down.
This QPST method is independent of the used ROM, it changes the profile in the EFS partition.
Sorry, can't help you more than this.
