CM 14.1 with VoLTE for Yureka/Plus : Update Guide

CM 14.1 VoLTE ROM update guide for Yureka/Plus. Install unofficial CyanogenMod 14.1 Nougat 7.1 ROM on Yu Yureka and Yureka Plus.
(Last Updated On: July 1, 2017)

CyanogenMod 14.1 unofficial build can be installed on Yureka and Yureka Plus devices to experience android Nougat 7.1 features. CM 14.1 supports Enhanced LTE (VoLTE) feature on Yureka so that you can make calls over LTE network. I had already published a guide to enable VoLTE option on Yureka by flashing AOSP Paradox ROM. In case you’re a CyanogenMod fan, this guide can be utilized to install latest unofficial CM 14.1 on your Yureka device.

The ROM itself doesn’t support VoLTE feature. That means you have to manually flash the COS (CyanogenOS) modem file prior installing CM14.1 on your Yureka. The procedure is pretty simple and I will be guiding you throughout this tutorial to manually update your Yureka to CM14.1 Nougat 7.1 and enable VoLTE feature. volte rom yureka cm 14.1
