Hello All,
This query is regarding Redmi 2 Custom Rom. Is there any Custom ROM which supports VoLTE?
In India, Reliance Jio is launching 4G which will require VoLTE and hence this query. I have read that MIUI based on Lollipop base does support VoLTE but have not seen that option in Custom ROMs. Thanks in advance for help & comments
Edit
Basis feedback from users, to get VoLTE working following is solution:
1) One needs to first flash MIUI LP ROM (to get LP bootloader)
2) Second follow this by flashing ROMs like Orion, Mokee etc which supports VoLTE over LP bootloader
Read next post for details
Enable VoLTE in Redmi 2
The solution to get VoLTE working is following :
1) First, one needs to flash MIUI LP ROM (to get LP bootloader)
2) Second, flash ROMs like Orion, Mokee, RR, Project X, CM 13 etc which supports VoLTE over LP bootloader
3) Insert sim (example Jio for Indian users) and reboot. If required might have to create APN "ims"
4) In case APN "ims" doesn't work very well, pls follow this post here to replace apns config file.
That's it.. this will work.
Credits to multiple users from this thread. Cheers guys for being supportive

CM13 base Custom Roms does not support VoLTE
Im currently on Mokee with Jio sim & volte call does work. :good: I think cm13 too would work, Tesla didn't. Remember to be in lollipop firmware with volte support before flashing custom rom .

Can you try on DU latest build and confirm for me if it's working for you?
Cm-13
I am having a question.. When I'm using any custom rom and using my Jio 4G sim in any of the custom rom the performance isn't that great. For eg. If I'm getting 34mbps speed in MIUI then in any custom ROM i will be getting 0.5-1.0 Mbps speed. Can anyone tell me why is this happening and any workaround for it?

I tried d same..but calls nt wrkng..help bro
why install custom.. just install miui lollipop of redmi 2 prime and use VoLTE. it works
So in order to get VoLTE support on CM13, do you have to have Lollipop Bootloader and Modem flashed?
What about MM custom ROMs? Can anyone tell me for a fact if any ROM supports VoLTE. Also, can anyone confirm if this guide works for custom ROMs?
Can I Install the redmi 2 prime lollipop rom on redmi 2 1gb ram version are you sure it works, if not then what rom supports VoLte on 1gb redmi 2.
For me volte working perfectly
Cm 13, Zephyr, aicp, mokee

I read this somewhere in CM13 thread. Try these APN settings it should work
For volte go to network setting then select apn.
Add new apn with below details for volte
Name - jio
APN - ims
APN Type - ims
Rest of things you can keep as it is.
Also for 4g internet
Name - jio4g
APN - jionet
APN Type - default
Hi there! Unfortunately, i never got VoLte working on any rom besides miui and aosp 5.0. K kept on following all the guides found here and there for the fix but never got Volte working. At first i thought i'n the only one unlucky but there were some other users too like me searching for a fix. If you're the one then follow this guide to get Volte working on Nougat roms.:fingers-crossed:
Note: Make sure to follow the exact same procedure.
Prerequisites:-
Efs backup of Miui mm
cm14 firmware link - https://www.androidfilehost.com/?fid=385035244224398629
cm13 modified radios link-https://drive.google.com/file/d/0B_oG85LcjcuRbE1mQ25MMmYxYVU/view
Any Volte supported Nougat Rom
Steps
First flash miui mm rom and let it boot. If you see Volte then reboot to recovery and make efs backup (use alka or zcx recovery).
Now clean flash any Nougat rom i flashed RR 5.8.0, then flash gapps and flash cm14 firmware and reboot.
(IMPORTANT STEP) If Volte is not working for you then reboot to recovery and flash cm13 modified radios (no need to wipe anything) and then finally restore efs and reboot.
Now you'll see hd icon but no service in sim 2 since we flashed cm13 radios. So, now do this final step. Now reboot to recovery and flash again cm14 firmware and then restore efs and reboot.
Now you will get Volte working and sim2 too.
Trying right now on aoscp!

I'm sorry but it seems Aoscp rom doesn't support volte by default. It needs to be patched. Volte patch for different roms is available here -> http://forum.xda-developers.com/redmi-note-3/development/volte-patches-nougat-based-cm-roms-t3509257
If still Volte is not working for you then follow my guide. It's just a guide to get volte working for some users for those volte wasn't working.

Well aoscp does support volte in a test buid which the dev posted in the thread. It has not been added in OP yet. Anyways, I tried this guide but didn't work for me.
please hlp
i tried almost every thing avilable on xda and miui forms ... follow the exact thing on the guids ..but no luck ho... really fed up can any one help me???? tried al most all roms avail on xda which supports volte but no luck
Volte in sim2? R u sure??
Didn't worked...I had the efs backup of 6.11.3 version miui so didnt flashed it...n followed the procedure as mentioned but no success.
Volte works flawlessly on 7.1.0 version ROMs n not on 7.1.1 versions ROMs (for me)
Can me tell me what you modified with cm 13 radios zip .u deleted others except modem aka Non-Hlos.bin.also flashing cm 14 firmware and restoring efs again cause no volte issue except on official rr and Abhishek's cm and santhosh cm.
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.

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

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?
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.
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:
