If you're unfortunate enough to encounter a problem on your Nokia N8, a hard reset maybe what you need to do. This wipes the entire phone memory and settings fresh to how it was (or should be) when you bought it. It's also useful if you're also unfortunate enough to have to send away your Nokia N8 for repair or exchange, or maybe in future you maybe selling it and don't want your information/details/media stored onto your device for someone else to access.
Hopefully unlike the N97, the N8 will not encounter hard-reset bugs where we constantly have to hard reset.
To hard reset the Nokia N8:

1) Turn off your phone
2) Hold "Volume Down + Camera Key + Menu Key" and press power button until your phone vibrates.
3) Wait until screen show properly... and welcome back!!

how can u take the battery out ov a nokia n8, it is a sealed unit doesnt have a removable battery.....

If you had had virus problems or if this started to happen after a software installation, you better try restoring your PC to an older state. Go to Start->Accessories->System Restore. Select a date before the problem started. Restore your PC. If the problem still remains, comment back. Also if you have ZoneAlarm, try uninstalling it. That might be the problem in some cases

plz change your lcd
