Master reset

Master reset from settings menu

A master reset restores the original factory settings and may delete your personal data on the internal storage, such as downloaded content, ringtones, images, apps, and contacts. It does not delete data stored on the SIM card or SD card.

To perform a master reset, follow these steps:

  1. Back up all data on the internal memory.
  2. From any Home screen, tap the Menu key.
  3. Tap System settings.
  4. If necessary, tap the Menu key to switch to list view.
  5. Scroll to 'PERSONAL,' and then tap Backup & reset.
  6. Tap Factory data reset.
  7. Tap Reset phone.
  8. Tap Erase everything.
  9. Review the warning, and then tap OK.
  10. Wait for the system to reset and do not remove the battery.

Master reset with hardware keys

If the device menus are frozen or unresponsive, you can master reset using hardware keys.

To perform a master reset with the hardware keys, follow these steps:

  1. Back up all data on the internal memory.
  2. Power off the device.
  3. At the same time, press and hold the following keys for 8 seconds:
    • Power key
    • Volume down key
  1. When the 'FACTORY HARD RESET' screen displays, release the keys.
  2. Press the Power key to confirm the reset. The master reset will automatically start.

Safe mode allows you to turn on the device with third-party apps disabled. Then you can easily remove all apps that may be causing a conflict or software problem.

  • From any screen, press and hold the Power key.
  • Touch and hold Power off.
  • Review the 'Reboot to safe mode' screen,' then tap OK.
  • The device restarts and 'Safe mode' appears in the lower-left corner.
  • Uninstall third-party apps as desired.

Turn off safe mode

To turn off safe mode, follow these steps:

  • From any screen, press and hold the Power key.
  • Tap Power off and restart.
  • Tap OK.

There's no need to bump your own thread, especially since it's a guide.

You should add to the OP that a full factory reset will NOT occur if the laf partition has been zero'd out to enable fastboot. Already been there and done that
