  • The instructions given in this guide are meant for the European variant of Galaxy Note 4 with model number SM-N910F and SM-N910G only. Verify device model number by navigating to Settings > About Phone.

  • Back up data and settings using a recommended custom recovery tool, like ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup. In Recovery, choose Backup and Restore and tap Backup.
  • Verify correct USB drivers for the phone are installed on the computer (download Galaxy Note 4 USB drivers).
  • Enable USB Debugging mode via Settings > Developer Options (if running Android 4.0 or above) or Settings > Applications > Development (if running Android 2.3 or earlier).
