Enter a Puk code

To unlock blackberry curve 8520 password screen, you must entering any password 10 times and your blackberry automated erase all your data and you can setup new password for your phone. But make sure you have backup data before you doing that since after your blackberry unlocked there is no chance you can save your previous data.

Just enter the incorrect password x10 times and your Blackberry will be wiped. Your personal data will be gone, but you can then enter a new password and start again.

only solution is to enter password wrong 10 times, beware by doing this you will loose all your phone contacts messages etc. then it will wipe the handset and ask for new password.

Best thing would be to backup (if you have not already) the data on the phone using blackberry desktop software..

And then reset the phone..

enter 10time wrong code your phone will be master rested and all data will be erased

Try entering password using blackberry desktop manager, then blackberry desktop manager will prompt you to enter password .

If you are locked out you can enter the wrong password several times and the phone will restore to factory settings. The downside to this is you lose everything unless you used the backberry server and saved!

What do you mean? Did you forgeting your blackberry password? If yes, you can unlock blackberry curve password with your puk code, just type any password until your phone asking you to enter puk code. PUK code can you found from your sim card bundle if you don't have it just call your service provider, they will give it to you. After you put that puk code your blackberry unlocked from old password.

Enter 10 wrong codes, then your blackberry will prompt you to set new passord .

you need to enter the code incorrectly 10x for it to reset , this will blank all information.
