How to unlock nokia lumina 520
Sorry! As its name suggest, CellUnlocker is for unlocking mobile phones (cells) so they can be used on any network and are not locked to just one. It does not unlock a pc password. I would suggest taking the pc to computer repair shop - they can usually find a way in. Otherwise, google the question - "I've forgotten my computer password, how do I reset it"?
Phone CellUnlocker, pay a nominal fee, you'll get an unlock code and simple instructions emailed to you in minutes. Follow the instructions and in less than 2 minutes your phone will be unlocked. One thing, make sure you have a sim card from another phone company before you start. You'll need to put this in the phone before entering the unlock code.
