  • Android USB drivers for your device should be installed on your PC, or you can download USB drivers for Google Nexus
  • Keep your battery charged or at least your device should contain at least 80% charge before the flashing operation.
  • Enable USB debugging and check the Allow Mock Locations option too. To enable USB debugging in your device go to Setting >> Developer options >> USB debugging. USB debugging is meant for the development purpose hence it will ask you for the confirmation so tap OK to confirm.

Tap it 7 times until a pop up arises with a message that you are now a developer, that’s it now go back and the Developers option is visible in the settings menu.
