I have lineage-14.1-20171001 on my op2.
Till now I had to use a heavy(drains a lot of battery & cpu) app for Volte functionality (on Reliance Jio ).
I went through some threads on how to get volte working on lineageOS(op2) and found this one
https://forums.oneplus.net/threads/how-to-get-volte-on-lineage-os.505343/page-2
Someone posted oos firmware links : https://androidfilehost.com/?w=files&flid=53150[/url] by @Spannaa
I flashed OOS 3.6.0 firmware and Volte started working!!
And I got a new "HD" icon on the status bar as well as "Device is HD capable" notification.
I tried calling using the dialer and it was smooth.
Sorry if it's an obvious solution , just wanted to share.
EDIT1: I have franco kernel ( if that helps )

I assume this is for Indian market with A2003 model of the phones, right? I'm in US market with A2005 model and I cannot get VoLTE on any custom ROM, except OOS 3.6.0...

Damn! I hope lineage makes one working volte build by combining new oos firmware but I am still confused why the same method is not working for your phone ? What's the difference between a2003 and a2005 except memory ?

As far as I know everything is identical even memory. The only difference is with 4G/LTE network bands.
A2003:
LTE Cat4 800/850/900/1800/2100/2600 (Bands 1, 3, 5, 7, 8, 20).
TD-LTE 2300/2500 (Bands 38, 40, 41).
A2005:
LTE Cat4 700/850/900/1700/1900/2100/2600 (Bands 1, 2, 4, 5, 7, 8, 12, 17).
Somewhere here is the cause of the issue internally in all the custom ROMs that is not the case with OOS 3.6.0. But since most if not all development is done on A2003, this will never be resolved, unfortunately.

It's a known fact that VoLTE is not supported in any custom ROM for this device as of now. I saw some people saying that flashing the radio zip enable the "Enhance 4g Mode" in settings. I'm on slim ROM without any radio files. If you have flashed the files and see that option, please let me know. Because I don't wanna fix anything that is not broken.
BTW, what does the radio file contains? MM Bootloader? And if I flash it, will I be able to go back to MIUI 8 global(5.1) backup that I made with TWRP without any issues. Your help will be appreciated.

Hello all,
Does somebody know about official CM 14 if will be soon available for onyx device?
I saw the latest releases are for oneplus 1 and 2 and the only missing device in oneplus is the onyx device.
Thanks in advance for your replies.
It will be available soon..if OnePlus One gets the official nightly then the next is onyx's turn.have patients.
Still some huge bugs to work out with data and camera. If you want a taste of Nougat I've personally tested Aosp-Ext and Tesla-N. Both stable and full functional. Just need footej app for video recording.

I've already tried it, from twrp41. And also tried flash cm-14.1-20161220-NIGHTLY-onyx-recovery.img from fastboot.
I think it could run if I make factory reset, but I don't want loose data(reinstall apps, configure it), I just want update. Maybe, I can do backup, then factory reset, then install cm14, recover backup? So, for this variant, what data I need to backup?

I think the kernel is faulty in this version because it doesn't boot for me either. I updated from the last unofficial version to first nightly and got stuck at 1+ logo bootanimation.

Thanks Philliped346 for those links. Where is the thread about los16 on 4PDA ?*Is it in the global thread related to Redmi 3 / 3*Pro ?*Because I didn't found it. Do you know if it will be monthly updated with security patches ? I suppose there will be no ota since it's unofficial.
Currently testing it, seems to work fine, but I have a problem with usb connection with the computer. I cannot connect it, everything is grayed out (see screenshot). Same for you ?

ambient display doesn't work at all
try O2 kernel ===>stuck in mi logo
so much lag in paly pubg
finger-print so slow
just a bit LOS16 better than RR7
and overall i've experience gsi so much smoother than these even for usual daily usage

It all depends on your carrier whether they've implemented Volte in your location or not, no extra steps are needed.
