UPDATE : JIO VoLTE APN Settings for Meizu M3S (Only for Flyme 6 China Firmware) Check my Threadhttp://forum.flymeos.com/thread-15591-1-1.html

Very First Flyme 6 China Firmware has been released on 30 December 2016! <strong>Main Thread of Flyme.cn</strong>

Dont worry just flash with wipe option select. Its fully english supported. Sims are working too in my M3s. Select the English Language as usually after flashing, on language selection section. And on my m3s, i am not getting VoLTE, but the option is there.
If you want to go back to normal Flyme, Just Flash Global/Indian Firmware ZIP of Flyme on your phone with Wipe Data (RECOMMENDED)

Visit the download site with Google Chrome to translate. select public version with all phone or your sim wont work most probably. And its in beta, so after that select Trail (which means BETA).


Flash like normal upgrade. but dont forget to select wipe data option(RECOMMENDED) !
