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.

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

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.

Hello hai to everyone..
Recently i flashed official lineage 14.1 os custom rom on my zuk z1 but I'm faced calling sim switch problem And i found that calls with option is disabled..Not able to enable it,I think it's a major bug...can anyone fixed please let me know.
I tried with both airtel Sims and as well as airtel and jio sims but problem is still unresolved only one sim is working to make a call even i though I'm using two airtel sims but not able to switch between them.
But I'm receiving messages as well from second sim only calls switching between sims is not working...first sim always enabled as the default sim to make a call.
I'm also unable to see the call screen while in a call therefore unable to hang up or dial numbers during a call. It simply does not appear at all (after selecting the person to dial it just rings them in the background)
I am also face this problem
I think this is one of the major issue every Zuk Z1 user is facing. Same here. Probably we should ask the users who has upgraded from CM 13 to LOS 14.1 and check even they are facing this dual sim bug or not...also I think flashing Zui will solve the problem, but is the image/zip file for Zui 2.5 (Android 7.0) is available anywhere?

Hexagon for Z1? I flashed the same on Yu Yuphoria and in the first boot, the boot logo kept on animating for half an hour, I gave up hope and flashed RR (Nougat). With Z1, any such issues did you face? And sim bug is gone or what because after LOS 14.1, I flashed RR 5.8.2 hoping the bug will go away, but that's not the case.?

sims working perfect and I haven't faced any problem but before flashing make sure that you have to wipe data,cache,system,boot folders.Take a backup before doing this process.
thank you.

I also have sim switching​ problem in my zuk z1 after installing Los 14.1.......
The call switching problem occurs since the baseband is not updated to correctly interact with Nougat. (As far as I know)
Flashing the ZUI zip corrects that since the modem is also updated, ZUI being an official software, and the company providing the updated modem files.
You can try updating the modem only, using fastboot commands in the bootloader with the modem file from ZUI zip and onto the modem partition.
Or you can wipe the device and do clean installs twice with ZUI, and LineageOS again.
Here's the link for ZUI 2.5 (Nougat) I used :

Try flashing NON-HLOS.bin from the zui zip using "fastboot flash modem *filename*" in bootloader mode.
**I haven't tried this so do take backup.**
And my problem was solved by clean flashing ZUI only. I used 2.5.115 beta version. I am currently using LineageOS, latest nightly from 4 April.

I'm facing a serious problem. Whenever I try to call through my Jio SIM card via VoLTE I constantly lose signal. While calling signal disappears completely on both sim cards, jio and airtel. I'm currently using latest miui 8. I tried using developer and stable MIUI rom and the problem still persists. I also tried using AOSP based ROM but the problem stil persists moreover, on AOSP rom I'm facing random reboots while calling. :crying:

Need help!
I'm currently on resurrection remix (unofficial build).
I'm using two sims on my phone(Airtel and Jio).Data from Jio sim is working perfectly fine but volte is not working .
Guys if possible please help!
Thank you in advance.
Flash the latest OOS firmware and check again. It is supposed to fix all that stuff
I unlocked my phone then flashed recovery by a rooting method provided on this forum. After getting 64bit recovery and root access I flashed PixelExperience Rom 64 bit on which i didn't checked if i had Volte working.
Now after changing several other roms (64bit Oreo) I m now on NitrogenOS without Volte working.
I haven't downgraded to stock after updating to oreo so why am i facing the same issue as "Volte gone forever".
I have tried voenabler magisk module and other sim changing method but nothing works.
There are people with same carrier(Jio) and same rom as me with volte calls working without issues.
Is there anything I can try? Switching to Nougat Roms would help? Will it also break Volte?
Maybe another person's EFS backup may help who has volte working on oreo?

Try switching any custom ROM apart from stock ROM, stock ROM is what broke VoLTE.
Nitrogen had VoLTE problems in the past builds but the latest build has fixed that so also check if you're on the latest Nitrogen.
Changing to nougat custom ROM will break volte?

I am having the exact same problem. I flashed RR Rom but after that I flashed back the stock rom and bricked my phone after installing an update. Although I recovered my phone and now I am using PixelExperience Rom but the Volte is not working.
I was able to fix, for the most part anyways, voLTE using the method described here:
Solved-volte-fix-lost-flashing-stock-rom <-Should be a link, but the forums are a bit crap.
8m now back in RR 8 1 with voLTE working. I lose it about once a day, but a restart fixes it.
Slightly annoying, but solely the fault of Lenovorola dragging their feet with regards to offocial Oreo on our devices. Their updated ROM should take care of any libgering issues from the move to 64-Bit. Unless they're straight up incompetent and fail to issue a proper fix for us.
