The S60 Codes to know

The codes aren't published officially by Nokia, anywhere I've seen or read, and yet they have been covered by many sites and still frequently asked for by users everywhere. A new year seemed like a good time to review these useful codes. Use these codes at your own risk. [I will not be responsible for any damage of any form]

• *#06# - IMEI (serial number).
  Structure of the IMEI:XXXXXX (TAC) XX (FAC) XXXXXX (SNR) X (SP)
  • TAC = Type approval code
  • FAC = Final assembly code
  • SNR = Serial number
  • SP = Spare
• *#0000# - Phone model, Firmware version and date
• *#7370# or *#res0# - Full phone format, wipes everything clean. Default security code 12345 until changed by the user.
• *#7780# - Phone reset, clears settings without deleting most data. Default security code 12345 until changed by the user.
• *#7370925538# or *#res0wallet# - Deleted everything in the Wallet, in case of forgotten password.
• *#92702689# or *#war0anty# - Lifetime timer, doesn't work on some older S60 devices and with older Nokias activated additional menus which has since been disabled or removed form the consumer firmware, now requiring a special Field Test firmware.
• *#2820# or *#bta0# - Displays the device's Bluetooth MAC address.
• *#62209526# or *#mac0wlan# - Displays the device's WLAN MAC address.
• [Green]+[def3]+[*+] - Fail-safe reformat, us this as a last resort if the regular format codes do not work or if the phone won't completely boot normally.
