Be Glad your the lucky person as of today morning Jio Forced Pushed some update on my device, Launcher was Blank nothing loading, connected the keyboard and was able to switch applications and use them but no access to home, using remote i was able to open livetv. jio cinema and my jio apps only,
When pressed Home, it got stuck to Blank Black Screen (so be safe just incase if this happens to you do not try to reset button in the bottom)
Finally i deciced to use the reset button and it formatted everything and now everything is gone.
