The default security code for Nokia is 12345. You can recover the password. The best way is to download a file manager to your phone. I use Best Fileman for my N70, from http://www.smartphoneware.com/ It’s for series 60and 40. The trial version should be enough. In the file manager (when installed on your phone) you’ll find under- C:\System\mmcstore -the file you’re looking for, you have to rename the file- mmcstore.txt -then send it to another mobile (best way) or your PC via luetooth or USB, open it on the other phone and your password will be revealed. Rename that file- mmcstore.txt -to just- mmcstore -there might be another file named- mmcstore.txt -to view your password rename one or the other- mmcstore1.txt -one is for your phone PIN number the other your MMC card.
If you reset (format) your phone you will lose all the data stored on it. Resetting sometimes gives negative results. You can reset it through your menu, if you can switch the phone on of course.
Using the reset code is not recommended,so keep it the last chance.
Try this for hard format: Take your SIM card out.Make sure your phone battery is fully charged.Press * 3 send at the same time and turn the phone on. Keep them pressed until the reset screen appears.
Give it time to reset.
