To perform a hard reset on a Samsung i220
- first make sure handset is off
- press the power button
- as the SAMSUNG logo starts to appear press and hold the LEFT SOFTKEY and the RETURN KEY (the curved arrow next to the power key)
- when the REBOOT MENU comes up PRESS OPTION #1 and the screen will turn pink and say its formattiing and thats it!
THE HANDSET RESTART SLOWER THAN USUAL! Dont worry that's because it resetting back to default factory settings.
