I'm having a really odd problem with my Nokia E71 phone. I've set up the security lock code to a numeric code (8 digits). As it's a well known date for me, I'm pretty sure to know the code but I can't unlock it anymore. I've tried every possible combination for a date (yyyymmdd, yyyyddmm, yymmdd, ...) but it still refuses to unlock.
I've pressed the FN-Key 2 times to activate numeric typing - maybe it's related to the input method?
The Nokia care center in Munich want to have 30€ to unlock but I don't want to pay if this is a problem of the phone and not me unable to recognize the code I've entered just hours before...
I'm really shure to have the right code but the phone won't unlock.
Anybody having the same problem or any hint how to reset the security code wihtout paying 30€?
The security code has been known to reset to the default under certain circumstances so I would definitely suggest trying the 12345 default code just in case.
Also look here for more information, but it is likely that you will have to spend the €30. They will probably also require proof of purchase/ownership.
