Resetting a Kyocera Domino phone will take around an hour, so make sure you don't need the phone for a while. Remember to jot down your phone number, passwords, activation codes and other important details before you perform the reset.
- Charge your the phone's battery to its maximum. Turn off the Domino, then remove the battery. Wait for 30 seconds then replace the battery and turn on the phone.
- Access the settings menu. Select 'privacy,' then 'factory data restore.'
- When asked, confirm that you do wish to delete all personal data. If asked whether you want to delete the SD card, select 'yes.'
- The Domino will then begin to reset, and this could take 30-60 minutes, depending on how full the memory was to begin with. Once it's done, you can input all your personal details and settings.
- If you've lost the manual to your Kyocera Domino, you can download another copy from cellphone.manualsonline.com. Or mymobilenation.com/_media/images/support_library. It is strongly recommended that you consult the phone's user manual before performing a reset on your Domino.
