Any Custom ROM Supporting VoLTE ?

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

Which Mokee, Lollipop or Marshmallow?

Hi.. I don't know why. But jio 4g sim is not working in my cm13. I was rocking the stable miui 7 build that's v7.5. Its working fine in that. I have had no luck in making it work in cm13. Please help

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

[Guide] VoLte fix on Nougat Roms (for some users)

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.

Had you taken the official Nougat OTA update? If so, you are out of luck... you will have to restore stock and wait for updated ROM's after the kernel source is release (30-90 days). There was a change in the partitioning and RIL that prevents custom ROMs from working at the moment, so you will have to go back to stock.

Yes, and for that kernel source and binary blobs to be implemented into custom ROMs, until then custom ROMs will not work properly.

I downgraded to official marshmallow rom and then the custom roms started working fine. But that can be very risky and you can brick your device.

Just flash global Dev. ROM from miui site, then once you in lolipop firmware, install twrp & flash the nougat rom ( no need fastboot, it's more difficult )

I don't think redmi 2 prime variant will work on this device as this device has only 1 gb ram where as prime has 2gb ram
Correct me if I am wrong..

Im using the same device 2014818 1gb variant.
It is wt88047.
U can use custom roms on KitKat firmware without any problems.(no volte)
Dont flash miui Lp coz soon when u switch to kitkat again from lp miui u will face sim card switch issue due to changed baseband. And miui lp will be slow on 1gb ram variant. But in kitkat firmware , linagge os and other 6.0.1, 7.1.2 ROMs will work.

1.For MM Stable Nx Rom by Anderson is stable and Tesla Os MM Stable.
2.Bootloader ( Firmware) There Are 2 Firmwares Available One is of Kikat and lollipop (Lp Firmware for volte ) they both are 50 mb. They can be flashed in twrp.
If ur using 2gb prime phone then flash lp firmware. Get it from xda threads.
Then flash a custom rom or miui lp and get volte function.
3. Manually set to 4g network from dialing *#*#4636#*#*
Enter into phone information and select lte , it won't go back to 3g or 2g then.
If u want the firmware links PM me.
4. Once u flash lp firmware u won't be able to work on miui kitkat. So when u flash miui lollipop the phone performance will be so slow due to 1gb ram..it isnt enough for background apps to run. So if u want to revert and go back to miui KitKat just make a backup of miui kitkat (System, boot , firmware ,Efs <- (efs is important coz it contains imei number which gets sim working) before flashing lp firmware. So u can restore easily from twrp.

Yes all custom roms doesn't provide gapps...install arm pico gapps
Mokee rom i tried few months later, it had battery draining issue.
Root access is already available in developer options no need of supersu.
Im having the same device as u have. Don't flash custom kernels it has overclocked cpus nd gpu and doesn't provide good multitasking.

How to deceive bootloader check

Hi guys, i have a custom kernel to flash in order to make my Nethunter app work properly on a s7edge, but this kernel is based on 6.0 marhsmallow kernel, and now i have a 8.0 oreo android version, that means i cant downgrade to 6.0 becouse of the damn samsung bootloader.
Do you think it is possible to flash a 6.0 custom rom (i found on internet that bootloader check works on official rom firmware only) and then flash the kernel? Do you think it could work? Thank you
