Hi, I'm on the latest build of nitrogen OS currently, It seems the rom does not support VOLTE. Does anyone know a fix around it? My jio does not seem to work :/

Do some searching around. Not this thread, but other ones. Some threads say latest Nougat firmware will restore volte. Some say you have to do a full flash of an oos ROM (official, beta, or custom like freedom os) then clean flash this ROM on top of it.

The problem is that the ROM is unified, but the firmware to download in sourceforce is for 3T. Flashing 3T firmware on 3 will brick the phone, for sure. That was my mistake too...

Yes, firmware.. Hard brick.. Not very pleasant.

I use the ROM for about 2 weeks and I am really impressed. Just right amount of features, very smooth and stable, decent battery life. I have just one issue.. when I reconnect my BT head phones sound is terrible till I disconnect and connect media to Bluetooth.. And it can be caused by arise and sauron.

The recent sRGB changes appear to have made the effect really subtle. I can't really see the difference between sRGB on and off.

I am using this ROM for two weeks now and I am very suprised.
No bugs, random reboots or call echo, etc.

This is the best Oreo ROM so far.

    There is an official Thread now, so this Thread is out of order!


    I am NOT the owner or developer of this ROM!
    All credit goes to @xyyx
    We are all very thankful for his work!

    Please if you want to post something on this thread, do NOT
    -post something that was already said before
    -tell us bugs which are already well known
    -ask for new features as I am not the developer!
    -blame @xyyx for bugs or better, don't mention him at all!


    Link to the ROM

    OpenGApps unofficial

    Magisk Beta
    Firmware for OP3

    unofficial TWRP


    What is currently not working?
    - VoLTE, but Vo2G is working fine.

    Please do NOT tell us bugs which are already well known!
    It can be very annoying if everybody is reporting the same bug again and again.


    xyyx for his wonderful ROM!
    @topjohnwu for Magisk!
    @eng.stk for TWRP!
    @Nezorflame for his OpenGapps build server!
    @jamal2367 for the Firmware zips!

    They gave you a solution you don't want to try. If you aren't willing to change something to make it work then don't post issues and ask for help

    At the end of the day it's your ROM.

    Frankly all this VoLTE talk is incredibly annoying. If people want it so bad, they can learn to code and make their own.

    VOLTE is the main reason why I don't make thread here. Because volte's guys are very annoying. I tried caf telephony. It has some trouble with AOSP code. And I don't want to use hacks from Omni.

    As I wrote in Kenzo's thread:

    I don't force you to use my ROM. I fix bugs that doesn't require many commits from CAF.
    If you don't like something, please, use another ROM and don't write in this thread. Please.
    We should really curb this VoLTE thing for now because it's taking over the thread again it would seem. Just wanted to put the info up a little higher.

    For those of you who need VoLTE, there is currently no support on this ROM. The ROM developer does not use it, and doesn't want to code a workaround like in Omni. If you need VoLTE, I'm sorry to say it but you should go on Omni for now at least. Currently it also appears that magisk workarounds and system file editing doesn't really help either.

    The reason it isn't working is because the caf telephony sources have not been updated for Oreo, so that means that developers cannot get it to work officially because they need the base code to build on. Omni developer Maxwen decided to code support for it himself and that's why it works. It is safe to say that when the caf sources are released that all 8.0/8.1 AOSP ROMs will support VoLTE due to it being much easier and quicker to build off.

    Currently, if you depend on VoLTE, you're outta luck. If you have it but don't need it, switch your networks to GSM/wcdma if you can't disable VoLTE while keeping LTE connection.

    Just keep in mind that ROMs come AS IS, and you really don't have a right to complain too much. This is especially the case here on this thread. The developer here didn't even publish this ROM to XDA which means they didn't want to deal with the XDA community or anything. They make this ROM for themselves, and it's still nice enough that they let us use it. Some developers in the past when they haven't shared work on XDA flip out (within reason) when someone else does it, so thank you to the developer for being so chill about it!
    My VOLTE was going away after one reboot on latest OOS beta FW...

    All those VoLTE posts are USELESS.

    Once for all, no Oreo ROM will be able to fix it because it's UPSTREAM CAF thing. So stop flooding with 'it works', ' oh s*** it went away after a reboot' 'i tried firmware xyz and it doesn't work'

    It's a chipset manufacturer driver not yet available for 8.1.So if VoLTE is vital for you just don't use those roms and use STABLE roms. Using experimental ROMs has a price, be ready to pay it.
    Can someone share screenshot of this new fresh UI because mine is the same like previous..

    Here you go.
