Blackberry Curve 8520 Won't Unlock?

My blacberry curve 8520 wont unlock at all, i have a password on it and if i click any buttons nothing happens, whereas usually if you click the trackpad it will come up with the option to unlock, now it does nothing. 

  I have tried rebooting, hard reboot, taking out sim and battery and restoring the whole phone, nothing has worked, please help.


Many Thanks,

Hi and Welcome to the Community!

I recommend that you attempt to boot into Safe Mode:

  • KB17877 How to start a BlackBerry smartphone in Safe Mode

It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.

Good luck and let us know!

It may be a moisture problem, try putting it in uncooked rice for 2-3 days 



Hope this helps

i'm having the same problem and I figured out that if you hold down the mute button (at the top of the phone) for a few seconds, it should light up the screen and let you unlock

Hi, I sent the phone away and it was offered to repair about a month ago...
Thanks anyway,
