I am not able to figure it out yet. not working at all . i am trying to use it in india JIO 4G volte sim, so neither 4g volte is working nor 5g is working because band is different here. Baljeet had mentioned in another thread https://forum.xda-developers.com/t/...itching-the-firmware-on-lg-velvet-5g.4484481/ that swithing the firmware to em could work but im not 100% sure.
try this guide, i had it working just today for jio 4g volte https://forum.xda-developers.com/t/...all-carriers-unlisted-countries-also.4575655/
Yes, point 5,6 and is not needed to be followed, as soon as you insert sim after point 4 volte option will pop up in some time. AlsoI can confirm wht abeykp stated above, this guide works for LG Velvet european models:
I will try to keep this post as small as possible. This will enable Volte for Phone ranging from Lg g8x, g8 and V60 without root or modifying the system files. Many have posted ways to get it, Iam only trying to help out the small bits missing...forum.xda-developers.com
It's probably for us a mix of actions made first with the present tutorial, and then with johndaniel guide. Anyway, it works now! You get the (very) small VoLTE icon showing up on the left of the 4G/5G icon, and you don't fall back to 3g when receiving or making a call!
Keep in mind that the Field Test menu on the Velvet is accessed by code
#*462633*#900# and not the one mentioned in the other guide. You should also only need to go up to point 4.4, the APN point is not needed apparently for the Velvet.
I'll try it on the LG Wing, I guess it should work the same way.
I). Switch On The "VoLTE"
J). Now To Double Check That Your Smartphone Now Truly Has VoLTE Enabled,Repeat Steps A&B.If Done Correctly The Menu Should Now Say "VoLTE Provisioned Video Calling Provisioned Wifi Calling Provisioned " -If These 3 Are All Switched On Then You Have Successfully Force Enabled VoLTE On Your LG Velvet 5G LM-G900, Congratulations!
Great tutorial. But:
Even if I activate and turn on VoLTE by creating a config in UE, the phone still switches to 2G (GSM) when connecting a call.
So data does not work during a call.

Perhaps the problem is in a non-functional IMS? (three dots at the top in Testing Settings Menu/Phone info - IMS Service Status).
