Follow these steps from nokia discussion, it works:
» Click to show Spoiler - click again to hide... «
- Turn off your phone.
- Insert charger.
- Remove charger right after screen lights up.
- Wait a couple of seconds till screen turns off and just after that press power button.
- After standart vibration notification just put your charger in.
- VOILA! You can insert your PIN again and the phone boots normally!
if really cannot then do a hard reset, it will on back.
