Nokia Symbian smartphones have few important secret codes which retrieve important information such as phone’s firmware version, imei number, bluetooth device address and can also come in handy for doing soft and hard reset. If Nokia 5230 is your first symbian smartphone you may be unaware of these secret codes.Let’s go through them one by one.
*#0000# – Shows software/firmware version. Check the software version of ur phone and if its not the latest one follow this Nokia firmware update tutorial.
*#06# – It tells the IMEI number of your Nokia Cell. The IMEI (International Mobile Equipment Identity) number of each phone is different, its like finger print different for each and every mobile phone.
*#7780# – Soft Reset Code, It restores the factory setting without affecting your contacts, messages, files etc.It’ll ask for the lock code. The default lock code is 12345.
*#7370# – Hard Reset Code, on entering this code it’ll show you the same message “Restore all original phone settings” but this time it’ll erase all the data stored in the phone memory. So, use it only when some serious software problem occurs such as virus attack.Take phone memory data backup on memory card or PC before doing hard format.
*#2820# - Bluetooth device address for manually connecting to a Bluetooth device.
