You sir are a life saver, i have had LG velvet 5g phone since september 2022, but not able to get VOLTE working in india but following your guide i had it working today. I didnt have to do 5 and 6 number option, as soon as i inserted sim to modify network apn settings, volte option showed up on top and i made the first call. please update your title to include LG velvet 5g so it comes in google search as many are looking for a fix on this thread also. many thanks to you as I was not sure what to do with this phone any more. thank you :)
[LG G8X ThinQ Guides, News, & Discussion] Vuche:
Thank you so much johndaniel!

As abeykp stated just above, it works on LG Velvet 5G, and in Europe also, finally!

It's maybe a mix of actions with the post below, as I tried it first (it did activate the VoLTE option in the network settings, but was still not working for me):

https://xdaforums.com/t/guide-how-t...owifi-viwifi-lg-devices-lg-velvet-5g.4488803/

Now I can call & receive calls in 4G/5G without my network switching to 3G!

I also confirm that points 5 & 6 are not needed, at least on my network in europe. And I used OPEN and EU (it was actually already showing up in the line in IMS settings, but not under Test in point 4.4). I guess you can also use FR, IT, ES, CH, etc depending of the country you live in europe, it works for my country, but I kept EU as VoLTE might keep working when roaming or with another sim inserted.

You can add in your short (but so usefull!) tutorial that you have to insert the sim card before point 5, or you won't be able to get to the APN settings.

And for the LG Velvet 5G, Field Test menu is accessed with code #*462633*#900#

I will test it with my LG Wing 5G and will report if it also works.

Now I still have to get to the Field Test menu on my Korean V50S (sim unlocked STK model). Didn't manage yet to pass start the flashing process to cross flash with the Korean Open firmware, any help welcomed...
[LG G8X ThinQ Guides, News, & Discussion] DON2003:
Hi, I alo have Korean V50s, does you mean we still don't have Field Test menu? so no way yt to activate VoLTE on our phone?
[LG G8X ThinQ Guides, News, & Discussion] Vuche:
I don't have access to my V50S right now, but I think I couldn't get the Field Test, probably same model as yours.

Did you test this from darrelama:

---------------------------------------

in SVC menu, go to MID Info, see if you can modify NT Code. Once NT Code is not matched with stored one, field test menu will appear

----------------------------------------

Let us now if it worked for you.

The only problem I had with the V50S was that it kept going back to 3G when calling, and it didn't have one of the frequencies that is used in my country. So sometimes I was left without being able to take or make a call.

IF only LG would let us unlock all bootloaders freely, now that they left the mobile market...
[LG G8X ThinQ Guides, News, & Discussion] Surgemanxx:
You should be able to unlock the bootloader with the LG G8 method.Same 8150 chipet and same abl enginnering file will be used.
[LG G8X ThinQ Guides, News, & Discussion] Vuche:
Thank you Surgemanxx, I will try this method to unlock the bootloader.

But I don't think it will be enough neither to pass the model name to cross flash the Open firmware on the korean SKT V50S, nor to make the Field Test menu appear.

In the meantime I could check if I could change the NT value on the V50S, but It can't be done...
[LG G8X ThinQ Guides, News, & Discussion] darrelama:
If IMPL shows 0, you can edit NT codes.

Another way is to use LGUP "PDM" mode to change NT codes.
[LG G8X ThinQ Guides, News, & Discussion] johndaniel:
Be careful cross flashing, always first keep all luna partition and other efs backup. I had 2 lg phones dead for months , cause of crossflashing. Something in lg can trigger the baseband to not match and then its down hill, like no imei and even if able to enter imei in sv menu , the phone showed locked permanent.
[LG G8X ThinQ Guides, News, & Discussion] Vuche:
Thanks for all those infos. Will first try to edit NT code to enable Field Test. If I can already have VoLTE it should be working fine in europe and I might be able to activate other 4G 5G Bands.

If this doesn't work, I'll try to cross flash. Doing so with the Korean Open firmware might keep baseband, etc as it's suppose then to work on all korean networks I guess. We'll see.
[LG G8X ThinQ Guides, News, & Discussion] Surgemanxx:
The NT-Code can be edited in the FTM with a Hex Editor.Just pull it with Qfil,and look for offset 14000.Add the countries firmware you cross flashed to and it's fixed.You can beat partitions to death as long as you make sure you save all LUN 5 partitions before you begin.Modemst1 and Modemst2 is your main partitions in LUN 5 for IMEI,but it's best to save all under LUN 5.I cross flashed my V60 USC model for this very reason of this post.AT&T doesn't like unlocked devices unless they're Pixel,Samsung,or Iphones.
[LG G8X ThinQ Guides, News, & Discussion] frostt420:
it worked. but simcard has supported by provider in my country. i just selected country=ID, carrier=OPEN
[LG G8X ThinQ Guides, News, & Discussion] Cryomichel:
Please keep me updated ! I own a Korean G8 in Europe and miss calls due to no VoLTE.... First time I hear about this NT code modif ( thanks @darrelama and @surgemanx but it would be a life saviour for me as Korean G8 does not have the same cameras as american G8 so crossflash would break it.

Also, if this does not work, I'm curious about this Korean open software that I also noticed but no one seems to have ever trier it....

I have lg v50 v500n korean model crossflashed to em 40b firmware and now the problem

When i click ims settings just say not supported how to fix it?
[LG G8X ThinQ Guides, News, & Discussion] Surgemanxx:
Install this apk,and see if it will let you in the hidden menu.Also,make sure you have a folder named enable_ue in the main storage as well.
[LG G8X ThinQ Guides, News, & Discussion] rtyuakatsuki:
It cannot installed
[LG G8X ThinQ Guides, News, & Discussion] Surgemanxx:
Can you get in to the engineering menu with *#546368#*600#?
[LG G8X ThinQ Guides, News, & Discussion] rtyuakatsuki:
Yes i can get into the menu and the problem is when i touch the ims settings it prompt not supported
[LG G8X ThinQ Guides, News, & Discussion] Surgemanxx:
Like I said,make sure you have a empty folder named enable_ue in the main storage and then try.
[LG G8X ThinQ Guides, News, & Discussion] rtyuakatsuki:
Still same result
[LG G8X ThinQ Guides, News, & Discussion] Surgemanxx:
Make sure you have the underscore as well with the name of the folder,or it won't work. enable_ue just like that.That folder has to be in the root of the internal storage.

do you know what to do ?
[LG G8X ThinQ Guides, News, & Discussion] rtyuakatsuki:
Hi i've follow the instruction and the problem is when i save apn ims it wont saved how to fix that?
[LG G8X ThinQ Guides, News, & Discussion] johndaniel:
That is fine cause it already exists, certain carrier already push the apn with ims as apn. When u save u cant see cause of that. Follow other steps you will get the volte if ur carrier doesn't have whitelist for phone models.

thanks for the great post. i am using LG G8 G820QM30c android 11 .

i am from india

i done all the steps and right now i can call using volte but incoming calls not working.

in the caller phone it shows dialing screen with death silent.

ur help is much appreciated
[LG G8X ThinQ Guides, News, & Discussion] pizzaclaus:
Tried this on a LG V600TM running android 13.

The GPRI VoLTE/VoWIFi options are in their own area of the field test menu, but all the options are the same. Great guide.

Wi-Fi calling toggles are still greyed out, but VoLTE icon is at the top and a Wi-Fi calling banner will show during calls.
[LG G8X ThinQ Guides, News, & Discussion] johndaniel:
Are you using jio ?
[LG G8X ThinQ Guides, News, & Discussion] jaganeee:
yes
[LG G8X ThinQ Guides, News, & Discussion] johndaniel:
There is issue reported with lg g8x also, incoming doesnt work ,but outgoing does. All with volte enabled. Not sure if its 4g bands. This was only for jio. Other networks it works ok.
[LG G8X ThinQ Guides, News, & Discussion] C D:
I can confirm that a slight modification of this procedure gets VoLTE to work on T-Mobile USA's network on the BPT variant of the USA factory-unlocked LG G8 (LM-G820QM) on Android 11 which is not configured out of the box to get VoLTE (unlike the "open" USA variant). And the process of loading carrier profiles (MBN files) found here did not help enable VoLTE.

Here are some details and differences from the procedure in the original post:

Initially going into Field Test -> IMS Setting gives a pop-up message saying something along the lines of "not supported" even though I previously already created an empty folder named "enable_ue" in the main internal storage and then went to Field Test -> Universal Enabler -> Create New Config and checked the VoLTE, ViLTE, VoWiFi, and ViWiFi boxes.

So I repeated creating a new config and checking those 4 boxes again under Universal Enabler, removed my SIM card (not sure if this is necessary), and restarted the phone.

After that, IMS Setting under Field Test was accessible, showing the SIM slot / carrier, and tapping on that revealed the options in Step 4) of the original post. For Step 4.3), the GPRI VoLTE/VoWiFi options are in the main menu outside Field Test.

For Step 5), the SIM card has to be inserted in order to access the APN settings.

There is no VoLTE icon showing up at Step 6), but that may be something specific to American models as I have never seen a VoLTE icon in my other LG phones (V20 and V50) with working VoLTE. In the Phone information menu from dialing *#*#4636#*#*, the "VoLTE Provisioned", "Video Calling Provisioned", and "Wifi Calling Provisioned" switches are all grayed out but in the enabled position. Looking at the 3-dot menu on the top right and going to "IMS Service Status" shows that IMS Registration is registered, Voice over LTE and Video Calling are available while Voice over WiFi is unavailable.

VoLTE works fine as the LTE data icon stays up during calls. There is a Wi-Fi calling switch under Settings -> Network & Internet but enabling it either has no effect or just crashes Settings. And there are no video calling options in the phone dialer, so it can be assumed that only VoLTE is working. To get at least Wi-Fi calling to work, I guess cross-flashing the "open" USA firmware would be needed, which is something I'll try next.
[LG G8X ThinQ Guides, News, & Discussion] StvOchi:
Thank You Very Much @johndaniel :)

The process successfully worked on my LG G8 Sprint unlocked variant crossflashed to OPEN CA Android 12

After trying the other methods, even rooting this process finally brought volte to my device.
[LG G8X ThinQ Guides, News, & Discussion] StvOchi:
After enabling volte now all incoming calls in the call log are indicated as unknown.

Anybody know a fix?

thanks johndaniel for the detailed explanation

happy that i managed to get it working on my verizon unlocked G8

i notice some days the volte will disappear off the menu (easily solved by restarting ims service)

but this occurrence (volte disappearing) seems rather random and there are times when i did not notice for a few hours and ended up missing calls

does anyone face the same issue?

any way to make it more stable? (ie not to disappear randomly) or any idea what the underlying reason could be?

any way to make the phone alert when volte is lost so that I can manually go and restart the ims service?

thank you in advance.

If someone call me it works great ?!?! So right now I need to togle of Volteand call and tell them to call me and I can turn on volte and await their call :-) Not that great... So question is if I have some setting still in the IMS that kind of make this happend... I just checked the ones that you highlighted didnt change anything else that where maybe from the start enabled and needs to be disabled...

Hi,

I followed the guide and did as you and created an enable_ue folder as well as created a new config with checked Volte, Vilte, Vowifi and viwifi. And after continue following the guide the Volte sign appeard on my LG-V50, but I got this problem that when I call someone the call directly hangs up? But when I get a call it works great ?!? and If I slide the Volte button in the normal setting off I can make call (in old 3g) but then I cant take calls ?!?

Do you have any clue whats going on?

[LG G8X ThinQ Guides, News, & Discussion] C D:
Not sure. Seems like the configuration isn't quite right for your V50. What are your country/region carrier and V50 model?
[LG G8X ThinQ Guides, News, & Discussion] glidarlars:
LMV500EM a Hungarian version if I understand right...

IMEI 355826100132942

Country Sweden and carrier Vimla.

I set the country to EU as I saw someone else did and carrier I run as open.

[LG G8X ThinQ Guides, News, & Discussion] C D:
Looks like the fitting configurations may not be there since you are on the Hungarian firmware and there's no specific Sweden region available. You could try your luck with cross-flashing the firmware of one of the other regions (UK, Switzerland, Italy, Spain, Australia, and South Africa found here) and see if they work better.

[LG G8X ThinQ Guides, News, & Discussion] Lookasso:
Hi!

First of all thanks a bunch, I don't know what I'd done without your post.

I've a v60 LM-V600TM, and I confirm DE works for Germany.

The only thing is that it now takes a bit longer at startup before registering on the network.

I've some questions.

1. why removing the SIM?

I did the first time but now I had to hard reset for another reason (no volume control when listening to voice messages in Whatsapp/Telegram with the phone on the ear like it was a phone call and the display off. Do you by chance have a solution?), and I had to redo the whole VoLTE thing, and as I have nothing to remove the SIM here with me, I tried without removing it and it worked perfectly.

4.2) what are those for? It feels weird to select all those things without even knowing why 😬

4.3) you have the GPRI under IMS?

I have it under Field Test, and after clicking on GPRI I need to click on IMS to find those 4 options.

5) I skipped this point and it worked anyway. In my case the settings installed automatically by my provider have Name "O2 Internet", APN "internet", and APN type "default,dun,mms,supl,xcap". So, no IMS.

Do you think I should still create what you recommended even if it all seems to work already?

6) I guess you made a mistake, it should be "open IMS Setting, then Test"?

But I guess that the people who come here are capable enough to figure that out.

And some extra questions:

- in Field Test / GPRI / IMS, below those 4 options there is "common". If I click on it I find "use of usim or isim authentication". Is it important? I chose "both", just in case.

And at the bottom it says VoWiFi and if I click there there's the option "use geolocation information". I don't like to be geolocated so I left it in false, but should I rather set it in true?

- below "common" there's "registration".

There is find VoLTE and VoWiFi.

Under the former there's "VoLTE indication", and under the latter there's "VoWiFi" and "airplane mode". This last one was already selected. The other two I selected them just in case? Does it do anything?

- under "GPRI / IMS" there's also a "Ut/Xcap" voice, which can be activated or not. I activated it just in case?

That.

Thanks!

Not working for now on ky Korean G8 on LGU+ stock ROM with root and unlocked bootloader. The Telegram VOLTE FIX G8 module enabled the Field Test so I was able to do those steps but VoLTE still not working witht this method... I've tried ims names OPEN/FR, SFR/FR and OPEN/EU but it does not seem to work sadly. Any clue ?
[LG G8X ThinQ Guides, News, & Discussion] C D:
The phone probably still doesn't have the right configuration files for your carrier in Europe.

Next, I would try getting the European carrier MBN files from a KDZ firmware file from one of the other LG phones with the Snapdragon 855 chip that has a European model, like the V50 or G8S, by following the steps in this guide which you have probably seen before. I haven't seen specific firmware regions corresponding to France, so I'm not sure which particular available country would have similar or compatible configurations to your carrier.

If that doesn't work, then you could go one step further by extracting the OP partition from a KDZ file and manually copy it to your phone which you can do now since it's rooted (this is how I used to get VoLTE for some of the American carriers to work on my rooted Sprint V50 several years ago before they started enforcing IMEI-based whitelists).
[LG G8X ThinQ Guides, News, & Discussion] Cryomichel:
Thanks for your reply, was not able to find the MBN configuration files on several european G8S, G8X or V50 ROM. They seem to have a different way to manage network on a software level, even with the same SoC...

Could you please detail a bit more the OP Partition process ? I don't understand why I need to be rooted to do this ? Is it not possible to do it with QFIL ?
[LG G8X ThinQ Guides, News, & Discussion] C D:
I'm not familiar enough with QFIL to know about replacing subsections of partitions for it, but if you know a way to replace parts of the OP partition, then you can try that.

Otherwise, you need root access because you need to copy some files from the OP partition to the /product/op and /product/op/config folders which lie under the root directory. Without root access, you won't be able to write anything to these locations. In my case, the files I copied were cust.prop to the op folder and apns.xml, custom_apk_list.cfg, and telephony.xml to the op/config folder (of course I backed up the original files before doing this).
