there is two ways to do this and both worked cuz i tested it
first one is when you have disabled the security code and forgot it
..so when you try to get it back ..you don't remember what is the code ""you can see that you still have access to the phone but can't lock it again ""
okay ..so send this program to your phone "unlock me " install it >> and let it find the code for you
that was the basic
Now ...you forgot the security code and its not disabled "maybe you found a phone and it has a security code "
okay ...you will need a card reader for this take the memory card from the phone >>put it in the pc >> show the hidden files copy the file THC-NOKIA-UNLOCK.MDL into the folder "System\recogs" in the memory card put it back on the phone ...a screen will show up and say the security code has been reset to 12345 :) now put the card again in the pc ..delete that file so it don't keep reseting the security code and turn of the phone ..."by taking the battery out and put it again "
this works on S60 Nokia cells ...try it on your cell and tell us what model is it and if it worked or not
