Only those who have gsm gadget (a gsm box and a modified cable) can read the phone lock code(mobile phone technicians).

The only way to remove the phone lock code is by resetting or formatting the phone.To do this just simply follow this guide.

* turn off the phone and make sure battery life is at least 50%
* simcard and memory card
* turn the phone On and wait until insert sim appears on home screen
* tap "call" button then type this ----> *2767*3855#
* a black screen and eeprom reset appears,wait until the phone process is done and it will automatically restart your phone.

Now your phone is back to its original settings and all codes is reset to 00000000 (8 zeros) including phone lock code.

Take note that this procedure will delete all data in your phone,If you don't want important data to be deleted(such as contacts,calendars,messages etc.) then it is better to bring the phone to the nearest mobile phone shop near you and they will do it without deleting any of your important data.
