Hey guys, can anybody recommend me a custom rom which supports VoLTE and is based on Nougat or Marshmellow? I have SM-G900W8 (klte/kltecan). My operator is Jio and it only supports VoLTE calls! CM 13 does not support VoLTE and after configuring APN, I cannot use data connection (APN settings are correct). CM 14.1 help me use data connection but it also does not support VoLTE. In addition there are a lot of bugs in CM 14.1. Any help will be appreciated.
Galaxy S5 (SM-G900T)
For the past 4 years I haven't found any roms that carries Volte Which is very disappointing and very important when it comes to being on a call and using the web. For the past few month's I believed to try every rom that's available and no Volte which is ridiculous. However, I'm writing this post in gud hopes that this matter would be taken into consideration. PS Thanks!
I will start right off the bat that I know it works very well on all ROMS for those that are in India. But can anyone here confirm VoLTE working on any custom Nougat ROM for those like me on T-Mobile in USA? It works flawlessly on 3.5.6, but as soon as I wipe and flash any custom 14.1 ROM, I lose it. The feature is enabled in SIM settings (Enhanced 4G LTE Mode) is enabled, but when I dial out, data switches from LTE to H. So this means even though the feature is enabled, it's not working on Nougat on T-Mobile in US.
Anyone?

Did you try clean flashing including system?
First install 3.5.6 and then clean flash any cm 14.1 ROM (especially the latest one from grarak). Volte works fine..
Is your VoLTE capable sim in Slot 1?

I've done that several times to no avail. First it was just flashing the 3.5.6 modem firmware while I was on RR 7.1.1. Then after that didn't work, I clean flashed OOS 3.5.6 and tested VoLTE and it worked as advertised with HD logo on calls and VoLTE logo in status bar. I was then happy and clean flashed (everything but internal storage) RR 7.1.1, enabled the Enhanced 4G LTE Mode, but that didn't work. I'm on Official CM 14.1 now with same result.

Yes it's in Slot 1.
Are you guys in US on T-Mobile? No offense to you guys, and I appreciate your help, but I know you got it working great on Jio in India... That might not be the case for us in US. That's why I want to hear from another T-Mobile customer to check if I'm not alone.
Thanks
In mean time I'm forced to stay on OOS 3.5.6 as VoLTE is working great on it.

Official CM 14.1 hasn't implemented Volte function yet, try the unofficial build from Grarak in basketbuild or andriod host.
As far as T-Mobile is concerned, if you do have Volte enabled in 3.5.6 (ie if you can make volte calls using oos 3.5.6, then i dont see a reason why it wont work on cm 14.1 unofficial).
Check out android development for OP2 to get the latest link from grarak.
Also slot 1 or 2 it doesn't matter. If you get Volte in oos 3.5.6 then in unofficial cm 14.1 you'll get it.
Dont know about RR though.

Cheers mate, there are 2 different builds one from grarak and one from Seraph08. Try either one, both works fine.
I am using grarak and its stable and latest implementation of lineage.

or

Just tried Grarak's latest build based on new LineageOS....still no go on VoLTE. The feature was already enabled under SIM 1 settings and as soon as I dial out LTE switches back to H
I'll try Seraph's build, but I'm afraid it will be the same... Are you on T-Mobile and VoLTE works CM14.1 for you?
Update: tried both builds, VoLTE is not working Again, it's enabled in the SIM settings, but when I dial out, LTE changes to H/H+.
I guess it's just not meant to be... I'll stick to OOS 3.5.6 for now
Thanks for your help!
Was downloading Seraph's build while on Grarak's and got a random reboot which never happened tocme before...
Have you enabled Enhanced 4G LTE Mode for the sim? That's the switch for VoLTE. Hope it worked
If the HD icon comes in the status bar and on notifications, then VoLTE is active.
Also set network type to LTE only for better use.

The problem is I had it enabled, but HD icon never comes up and VoLTE seems not to work on any CM141. ROM. But it works perfectly well on OOS 3.5.6. So I am not sure why this is the case... I guess I'll stay on OOS 3.5.6, unless another T-Mobile US user will confirm or disagree with my findings.
I know very well you guys have it working on JIO in India... this is not the case for me in USA on T-Mobile

This is what I see.
I guess I have to try this again on a CM14.1 ROM to see what it shows
Last thing u can try up is Clean Flash OOS 3.5.6 again and then clean flash some CM14.1 ROM
Something might work out

I assume that you did a clean flash (including system wipe in TWRP) over 3.5.6. If not the network will be unstable.
In one of the screenshot posted by you (in some above thread) I can see that Volte is enabled, is it on CM or 3.5.6 ?
T-Mobile in US is supported by 3.5.6 (Which I can see from the screenshot). So the firmware got the capability of Volte..
As of now there are 2 possibilities:
1 (If you clean flashed CM over OOS 3.5.6) : Then network is not stable, Network guru app will lock the LTE band, so give it a try with that. (If you need detailed steps with Network guru i can tell you that)
2 (If not clean flashed CM over OOS 3.5.6) : Recommend you to clean flash it. This will definitely work (suggest you to go for grarak). If you face issues after this, do let me know. We can find other work around.
Hope this helps.

Hey man, first of all I wanna thank you for helping me, I know it's an annoying topic for many.
I'll answer in order.
Yes, I did a clean flash, by wiping everything except internal storage. The screenshots I posted are from OOS 3.5.6. By the way, my hybrid TWRP doesn't get overwritten, so at least I don't have a headache reflashing recovery image after everything OOS flash. Unfortunately, it hadn't worked yet... Firmware is definitely VoLTE capable as I have it working very well now on OOS 3.5.6.
As for your suggestions, I tried both builds with clean flash, but they don't work. I kind of gave up after flashing nonstop and just stayed on OOS 3.5.6.
I think you're right though, CM14.1 definitely don't have VoLTE fully functional, at least for T-Mobile users, maybe it has to due with Band 12 (700a) as this is the band used in US for enhanced LTE.
I wanna hear from some other T-Mobile use, but appears there aren't that many...
I've tried Network Guru app when I has network signal drops, but I'm a little confused how to properly use it. I don't have a magic wand button, but through menu I can get to Band locking screen and in LTE section I had everything checked off. I know in US on T-Mobile we use bands 2 (2G), 4 (3G/4G), and new band 12 (enhanced 4G/LTE). When in the past I only locked band 12, I wasn't able to make calls at all as H/H+ were not active.
I will try to see what I have working now with VoLTE enabled on 3.5.6. I do know I'm mostly on band 4 and in some places band 12.
Hope this info helps.

Are you also on T-Mobile?
HI,
I want to ask wether VoLTE is working for you IF you have Global RN7, With custom ROM (and your carrier and SIM supports VoLTE of course).
I have Global RN7 running on xiaomi.eu based ROM.
Before I flashed ROM from xiaomi.eu based the VoLTE was working fine for me, after I disabled VoLTE carrier check. But now with the xiaomi.eu based ROM, VoLTE no longer works for me. I already asked on the forum for my rom - that is miuios.cz - but it seems they do not know what to do with it.
Besides I tried a few other MIUI base ROMs as well as pure android based like LineageOS for example but VoLTE did not work in ANY custom ROM.
So, has it occured to you too, or your VoLTE is working just fine on custom ROM?
Do you know any way to fix this?
Thanks!
search around for the build.prop edit to allow it or you can try the magisk module voenabler-v1.8.zip https://github.com/edgd1er/voenabler/releases be sure to read the README.
if it still doesnt work refer to this thread:
