To hard-reset and format the C: drive of a Nokia 9210, do the following:Pull the battery out for a few seconds, then replace it. Open the case and wait for the “Nokia 9210″ splash screen (with the hands) to be displayed. As soon as it appears, hold down the following three keys for about 2 seconds: Shift, Ctrl and F. A screen appears asking for confirmation that you want to format the device. Select Format. All data on the C: drive will be lost, and the factory default settings will be restored. Thanks to Andrew, a recent visitor, for pointing out that a format is battery-hungry operation, and doing this this the charger connected may prevent a dangerous battery fail halfway through.
