My last phone was a Nokia 3568i and while it was a solid little phone it was definitely time for an upgrade. When I went to give the phone to my wife to replace her aging Motorola V60 I tried to reset the phone so she would start fresh but was stopped by a ‘Lock code” that I didn’t have. The phone was supposed to ask for a 5 digit Security code after 3 successive failures to enter the lock code. Unfortunately it wasn’t prompting me for the security code. The following code let me enter the programming mode of the phone where I was able to clear it’s contents and reset it to the factory defaults.
*3001#12345# Programming for CDMA/TDMA (12345 is your security code if you haven’t changed the default)
*#837# lets you check your PRL and software version.
*#639# will allow you to manually program your phone with the MIN and SID.
*#7780# Will restore factory settings
These codes saved me a trip to the cellular dealer!
