  2. Check for updates
     
  3. Install.

  
  

  Make sure you have at least 40 % battery, to prevent your phone from bricking.

  You can simply reset your Android to factory settings through "Backup and Reset" feature available in settings.

  However, this won't work if your phone has got hanged or you have forgotten the password.

  
  

  Here is a Quick reference to hard reset your phone:

  1. Power off your phone (If the phone is hanged, directly perform the next step)
     
  2. Press and hold Volume Down and Power button to enter recovery mode. (Old phone might use home button as well)
     
  3. After the Android logo, you'll be presented by a menu.
     
  4. Select "Wipe Data/Factory reset" from the menu.
  5. Press the Power button to confirm.
     
  6. Scroll to "Yes" and confirm with Power button.
     
  7. This will start the Reset Process.

  To root your phone manually, you need to turn on USB Debugging. 

  1. Go to Setting, Find kernel version in About.
     
  2. Tap it seven times, at which point you should see the message, "You are now a developer!" With that done, tap Settings, About Phone, Developer Options, and then tick USB debugging." Then tap OK to approve the setting change. 
     
  3. Now turn it ON  in fastboot mode and unlock the bootloader.
     
  4. Install a recovery to help you with flashing.
     
  5. Flash a supporting custom ROM and gapps.

  You don't need to enable VoLTE. Insert the Jio (VoLTE enabled) in any slot. By default, VoLTE will be active. If it is not, you can change the network preferences from Network option in settings.

  
  

  1. Go to Settings > Call Settings (Sim and Network)
     
  2. Tap Cellular networks > Enable Voice over LTE On/ Off.
     

  Alternatively, you can follow a much easier way:

  
  

  1. You can simply dial *#*#4636#*#* 
     
  2. Choose Phone information.
     
  3. Click " Phone Information" and Toggle VOLTE Provisioned.
     
  4. Restart the phone and you are done.
