        1. Hello Naresh Kumar,

          I have done all those procedure u said above.
          I can see the HD option and I can able to make jio calls.

          But because of installing this developer stock ROM ( Le 1S EUI 5.8.419D Dev Rom).

          LETV live gone
          APP lock gone, Battery temperature, quick charge,
          Playstore etc etc all gone.

          Though I select english before booting up I still see most of the things in chinese.
          I have managed to installed all indian playstore apps but is there any permanent fix for this?

          Most apps crashes and goes to trouble reporting page.

          WHAT SHOULD BE DONE TO LOOK LIKE A INDIAN PURCHASED LETV PHONE ALONG WITH JIO FEATURES.

          ** EVEN WITH DEV ROM ALSO THE JIO ENGG SETTINGS GO AWAY AS AND WHEN U RESTART THEN WHATS THE PURPOSE OF THIS DEV ROM ?? **
